karate run specific feature file karate run specific feature file

We can define each scenario with a useful tag. Karate can read *.csv files and will auto-convert them to JSON. It is important to note that myFile above is the field name within the multipart/form-data request payload. In the above example, the end-result of the call to my-signin.feature resulted in the authToken variable being initialized. In the first feature file creating a Git Repo. You can organize multiple common utilities into a single re-usable feature file as follows e.g. 'test1.feature', * def result = responseStatus == 404 ? 3 Day Blinds is the leading manufacturer and retailer . Karate was based on Cucumber-JVM until version 0.8.0 but the parser and engine were re-written from scratch in 0.9.0 onwards. JSON objects become Java Map-s, JSON arrays become Java List-s, and Java Bean properties are accessible (and update-able) using dot notation e.g. Either - it can be assigned to a variable like so. This approach is indeed slightly more complicated than traditional *.properties files - but you need this complexity. And yes, variables can come from global config. The structure should be a def keyword followed by a variable name and a value. This is a core feature and does not depend on JUnit, Maven or Gradle. It is worth mentioning that to do the equivalent of the last line in Java, you would typically have to traverse 2 Java Objects, one of which is within a list, and you would have to check for nulls as well. Do new devs get fired if they can't solve a certain bug? What this means is that you are free to use whatever makes sense for you. Heres a reminder that running any single JUnit test via Maven can be done by: Where CatsRunner is the JUnit class name (in any package) you wish to run. The $varName form is used on the right-hand-side of Karate expressions and is slightly different from pure JsonPath expressions which always begin with $. Here I have defined a variable expectedOutput with def keyword. This enables more concise tests, and the file can be re-usable in multiple, data-driven tests. The call keyword provides an alternate way of calling JavaScript functions that have only one argument. Calling a feature file from another file. } Heres thearticle. To learn more, see our tips on writing great answers. """, """ convenient way to execute an OS specific command and return the console output e.g. The example below shows the difference between embedded expressions and enclosed JavaScript: So how would you choose between the two approaches to create JSON ? Look at multipart entity for an example. { Here is an example of what is possible: Not something you would commonly use, but in some cases you need to disable Karates default behavior of attempting to parse anything that looks like JSON (or XML) when using multi-line / string expressions. But one pattern that you should be aware of is that JSON is actually a great data-structure for looking up data. In the example below, note the use of the karate.get() helper for getting the value of a dynamic variable (which was not set at the time this JS function was declared). Only recommended for advanced users, but this guarantees a routine is run only once, even when running tests in parallel. Karate is an open-source general-purpose test-automation framework that can script calls to HTTP end-points and assert that the JSON or XML responses are as expected. This is useful when you ship a JAR file containing re-usable features and JavaScript / Java code and want to default a few variables that teams can inherit from. Step 3: Add steps to run a sample GET API request. height To create a feature file, right click on the Project explorer, choose New >> File. You should take a minute to compare this with the exact same example implemented in REST-assured and TestNG. all the key-value pairs are added to the HTTP headers. Karate has the following short-cut symbols designed to be mixed into embedded expressions: For completeness, == and != also belong in the above list. Now it should be clear how Karate makes it easy to express JSON or XML. 1234 If you are familiar with Cucumber (JVM), you may be wondering if you need to write step-definitions. It is a great example of how to effectively use the unique combination of Cucumber and JsonPath that Karate provides. } Instead of using call (or callonce) you are always free to call JavaScript functions normally and then you can use more than one argument. Defining the request is mandatory if you are using an HTTP method that expects a body such as post. Note that regex escaping has to be done with a double back-slash - for e.g: '#regex a\\.dot' will match 'a.dot'. A few more useful transforms are to select a sub-set of key-value pairs using karate.filterKeys(), merging 2 or more JSON-s using karate.merge() and combining 2 or more arrays (or objects) into a single array using karate.append(). It is worth repeating that in most cases you wont need to set the Content-Type header as Karate will automatically do the right thing depending on the data-type of the request. Refer to the cats-java.feature demo for an example. JavaScript functions have some limitations when combined with multi-threaded Java code. Ideally you should return only pure JSON data (or a primitive string, number etc.). 3) Go to TestRunner.java file created in the step above and run it as JUnit Test. And this assertion will cause the test to fail if the HTTP response code is something else. Karate is flexible, you can easily over-write config variables within the Java or JUnit runner - which is very convenient when in dev-mode or rapid-prototyping. path to file containing the trust chain for your server certificate. In the rare case that you need to mutate a Map or List returned from Java but while still within a JS block, use karate.toJson() to convert. Read the documentation of the stand-alone JAR for more - such as how you can even install custom command-line applications using jbang ! The Background is optional. For advanced examples, refer to some of the scenarios within this demo: dynamic-params.feature. So how can you get this value injected into the Karate configuration ? Contrary to the docs, Karate does limit us regarding values we pass between feature files. There is a neat way to tag your tests and the above example demonstrates how to run all tests except the ones tagged @skipme. You can find a lot more references, tutorials and blog-posts in the wiki. Difference between "select-editor" and "update-alternatives --config editor". One pattern you can adopt is to create a factory method that returns a Java function - where you can easily delegate to the logic you want. "arr": [ Another good thing that Karate inherits is the nice IDE support for Cucumber that IntelliJ and Eclipse have. To make dynamic data-driven testing easier, the following keywords also exist: params, headers, cookies and form fields. So the only way to call this Scenario is by using the karate.setup() JS API. This comes in useful because depending on how you organize your files and folders - you can have multiple feature files executed by a single JUnit test-class. How can I see who wants to message me on Messenger? The tests eecutes fine if i use maven command or run from runner file( .java). The special tag @report=false can be used, and it can even be used only for a single Scenario: In cases where you want to mask values which are sensitive from a security point of view from the output files, logs and HTML reports, you can implement the HttpLogModifier and tell Karate to use it via the configure keyword. JSON arrays), see. mvn clean test-compile gatling:test -Dgatling.simulationClass=Performance.GatlingTest Gatling script with Karate feature file. This means that even when you have dynamic server-side generated values such as UUID-s and time-stamps appearing in the response, you can still assert that the full-payload matched in one step. Set the read timeout (milliseconds). "c": 3 This is very common in the world of Maven users and keep in mind that these are tests and not production code. UI for debugging the Test. { Note that the parallel runner will run Scenario-s in parallel, which means they can run in any order. It is also possible to invoke a feature file via a Java API which can be useful in some test-automation situations. Assertions and HTML reports are built-in, and you can run tests in parallel for speed. bottom: 893, Notice that in the above example, string values within the table need to be enclosed in quotes. You can always use a JavaScript function or call Java for more complex logic. You can also compare images using Karate path prefixes (e.g. subType: { name: 'Smith', deleted: false } When re-running tests in development mode and when your test suite depends on say an Authorization header set by karate.callSingle(), you can cache the results locally to a file, which is very convenient when your auth token is valid for a period of a few minutes - which typically is the case. Soumendra Daas has created a nice example and guide that you can use as a reference here: hello-karate. cucumber. This is for evaluating arbitrary JavaScript and you are advised to use this only as a last resort ! response is a built-in variable in karate that stores HTTP API response. If you have to set a bunch of deeply nested keys, you can move the parent path to the top, next to the set keyword and save a lot of typing ! It consists of the diamond-shaped Singapore Island and some 60 small islets; the main island occupies all but about 18 square miles of this combined area. Note that any cookies returned in the HTTP response would be automatically set for any future requests. Karate API Test Script. And there is another example in the karate-demos: schema.feature where you can compare Karates approach with an actual JSON-schema example. Refer to karate.tags and karate.tagValues. Note that def will over-write any variable that was using the same name earlier. HTML form fields would be URL-encoded when the HTTP request is submitted (by the method step). Some characters such as the hyphen - are not permitted in lenient JSON keys (because they are interpreted by the JS engine as a minus sign). After one year KarateIDE have reached Version 1.0.0.The best user experience for KarateDSL, by far!! so if you are going to pass any special characters as data via URL you need to % encode them to avoid conflicts. ##(subSchema) To do that, add the following: And then the above command in Gradle would look like: The recommended way to define and run test-suites and reporting in Karate is to use the parallel runner, described in the next section. Other errors could be a java.net.URISyntaxException and match not working as expected because of special or foreign characters, e.g. We will use karate.properties [user.dir] which will automatically pick users working directory and then append it to the path of our project files. Later, in the runner file, we can decide which specific tag (and so as the scenario (s)) we want Cucumber to execute. Karate supports JUnit 5 and the advantage is that you can have multiple methods in a test-class. It also details how a third-party library can be easily used to generate some very nice-looking reports, from the JSON output of the parallel runner. For example: While the tag does not need to be in the @key=value form, it is recommended for readability when you start getting into the business of giving meaningful names to your Scenario-s. This behavior where all key-value pairs in the returned map-like object get automatically added as variables - applies to the calling of *.feature files as well. Other options are the quickstart or the standalone executable. This implies that MantisBT issue is created in the bug tracker tool. What is the point of Thrower's Bandolier? { id: 42, name: 'Wild' } The answer is no. if you want to conditionally stop a test with a descriptive error message, e.g. if an API needs to be called to get a JSON array, you can call a separate Scenario to set up this data. The specific value here varies from request to request, so check the response value using Fuzzy Matching provided by Karate. So when you use the combination of callonce in a Background, you can indeed get the same effect as using a @BeforeClass annotation, and you can find examples in the karate-demo, such as this one: callonce.feature. auth tokens) only once for all of your tests. Note that url and request are not allowed as variable names. When using call (or callonce), only one argument is allowed. And when you read your JSON objects from (re-usable) files, even complex response payload assertions can be accomplished in just a single line of Karate-script. Since it is internally implemented as a JavaScript function, you can mix calls to read() freely wherever JavaScript expressions are allowed: Tip: you can even use JS expressions to dynamically choose a file based on some condition: * def someConfig = read('my-config-' + someVariable + '.json'). Note how JS functions defined at run-time can be mixed with custom Java code to get things done. Format of the trustStore file. # and even ignore fields at the same time ! Reading files is achieved using the built-in JavaScript function called read(). Billie But the when using Run option on an individual scenario, i get the following error The built-in karate object is explained in detail later, but for now, note that this is also injected into print (and even assert) statements, and it has a helpful pretty method, that takes a JSON argument and a prettyXml method that deals with XML. The examples above are simple, but a variety of expression shapes are supported on the right hand side of the = symbol. In This video explained how to set up the runner class so that the parallel execution is possible Follow me on LlinkedIn - https://www.linkedin.com/in/krishn. function() { Since replace auto-converts the result to a string, make sure you perform type conversion back to JSON (or XML) if applicable. You can also find a nice visual comparison and explanation here. After every HTTP call this variable is set with the response body, and is available until the next HTTP request over-writes it. OR: To run every feature that has either of the @F1 and @F2 tags (runs both) {@F1,@F2}, Combining OR and AND: To run feature that has either of @F1,@F2,@F3 tags but not @F4 tag. For convenience, non-existent keys (or array elements) will be created automatically. XML and XPath works just like youd expect. Short story taking place on a toroidal planet or moon involving flying, Doesn't analytically integrate sensibly let alone correctly, Full text of the 'Sri Mahalakshmi Dhyanam & Stotram', Equation alignment in aligned environment not working properly. So you have the following type markers you can use instead of def (or the rarely used text). Comma delimited values are supported which can be more convenient, and takes care of URL-encoding and appending / between path segments as needed. Karate makes re-use of payload data, utility-functions and even other test-scripts as easy as possible. an initial 'sign-in' that retrieves some secure tokens, every subsequent. Mac: Cmd+V. To force a null value, wrap it in parentheses: An alternate way to create data is using the set multiple syntax. Observe how the get shortcut is used to distill the result array of variable envelopes into an array consisting only of response payloads. Learn more. If you don't want to run Gatling tests as part of the normal Maven test lifecycle, you can avoid the <executions> section as described previously.. Gradle . name: 'Billie', Even Java interop and access to the karate JS API would work. There should always be karate-config.js in the root folder, even if you dont have any common config. Variables can be referred to within JSON, for example: So the rule is - if a string value within a JSON (or XML) object declaration is enclosed between #( and ) - it will be evaluated as a JavaScript expression. #string You can use karate.callSingle() directly in a *.feature file, but it logically fits better in the global bootstrap. """, * configure imageComparison = { onShowConfig, # don't embed the image comparison UI when the latest image is the same / similar to the baseline (e.g. You can easily select (double-click), copy and paste this file: URL into your browser address bar. VNC server exposed on port 5900 so that you can watch the browser in real-time. All feature files should be in src/test/resources and create the Cucumber Runner class as CucumberRunnerTest. note the wildcard '*' in the JsonPath (returns an array), # when inspecting a json array, 'contains' just checks if the expected items exist, # and the size and order of the actual array does not matter, # the .. operator is great because it matches nodes at any depth in the JSON "tree". Sometimes when dealing with very large numbers, the JS engine may mangle the number into scientific notation: This can be easily solved by using java.math.BigDecimal: Karate has a built-in HTML templating engine that can be used to insert additional custom HTML into the test-reports. Instead, Karate gives you all you need as part of the syntax. Do note that when passing JSON, the default Map and List representations should suffice for most needs (see example), and using them would avoid un-necessary string-conversion. A common requirement is to pass dynamic parameter values via the command line, and you can use the karate.properties['some.name'] syntax for getting a system property passed via JVM options in the form -Dsome.name=foo. The classpath is a Java concept and is where some configuration files such as the one for logging are expected to be by default. The following are some features of the Karate Testing Framework: Makes use of easy-to-understand Gherkins language. And in case we have multiple Gatling simulation files and we want to choose only one to run, we may use the following command. Instantiating a Java class and using this in a test is easy (see example): Since karate-config.js is processed for every Scenario, you can use a singleton instead of calling new every time. Because of the last rule above, note that string-concatenation may not work quite the way you expect: Observe how you can achieve string concatenation if you really want, because any valid JavaScript expression can be stuffed within an embedded expression. For this, Cucumber has already provided a way to organize your scenario execution by using tags in feature file. The following short-cut is also supported which will disable all logs: When you use a re-usable feature that has commonly used utilities, you may want to hide this completely from the HTML reports. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. { For suppressing sensitive information such as secrets and passwords from the log and reports, see Log Masking and Report Verbosity. For JSON and XML files, Karate will evaluate any embedded expressions on load. Let's have a look over the a very simple and plane gatling script which uses Karate . 7 How to pass data from one feature file to another in karate? Step 1 - Create a Gradle project. b But the recommended way is to use the karateEnv(name, value) or systemProperty(name, value) API on the parallel-runner. Something worth mentioning here is that you would hardly need to use assert in your test scripts. Parallel testing is the core functionality that is provided by the Karate itself, hence we need not depend on Maven, Gradle, etc. How to change the query variable in WordPress? #10, #15: There must be a structure expected as a response of the API. Assuming you use JUnit, there are some good reasons for the recommended (best practice) naming convention and choice of file-placement shown above: For details on what actually goes into a script or *.feature file, refer to the syntax guide. This is useful in any situation where you need to concatenate dynamic string fragments to form content such as GraphQL or SQL. And for dealing with binary content - see bytes. Type the following commands: mvn spring-boot:run & mvn test -Dtest=KarateTests. Here we want to call a file only if a condition is satisfied: Or if we dont care about the result, we can eval an if statement: And this may give you more ideas. Refer to the demo karate-config.js for an example and how the demo.server.port system-property is set-up in the test runner: TestBase.java. When the level is DEBUG the entire request and response payloads are logged. For example, here below is an actual report generated by the cucumber-reporting open-source library. Here is an example JavaScript function that uses some variables in the context (which have been possibly set as the result of a sign-in) to build the Authorization header. Since the karate object is injected within karate-config.js on start-up, it is a simple and effective way for other processes within the same JVM to pass configuration values to Karate at run-time. mass Any valid XPath expression is allowed on the left-hand-side of a match statement. If you really need to re-use a Java function, see Java Function References. Karates callonce keyword behaves exactly like call but is guaranteed to execute only once. Billie,LOL The only rule is that on start-up Karate expects a file called karate-config.js to exist on the classpath and contain a JavaScript function. The Runner.Builder API has a dryRun() method to switch this on. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. } Now I can dynamically able to select the list of features at run time :) Regarding the karate.abort() Now the result for the particular step is marked as 'SKIPPED', but the results for the steps below it still shown as 'PASSED'. Because Karate strips trailing slashes if part of a path parameter, if you want to append a forward-slash to the end of the URL in the final HTTP request - make sure that the last path is a single /. You can use karate.abort() like so: Using karate.abort() will not fail the test. Use this for building multipart named (form) field requests. params, headers, cookies, form fields, multipart fields and multipart files take a single JSON argument (which can be in-line or a variable reference), and this enables certain types of dynamic data-driven testing, especially because any JSON key with a null value will be ignored. It typically ends up being a one-liner that appears in the Background section at the start of your test-scripts. So if you tried to re-use the same feature but with multiple arguments, things will not work as you expect. After you define the URL, you need to define a path to send a request. Karate Tests you can immediately run, with validation, inline payload examples and . Note how triple-quotes (""") are used to enclose content. So it is recommended that you directly use a Java Function when possible instead of using the karate.toJava() wrapper as shown above. So if you return complex objects such as a custom Java instance or a JS function that depends on complex objects, this may cause issues when you run in parallel. Karate can run tests in parallel, and dramatically cut down execution time. Although all properties in the passed JSON-like argument are unpacked into the current scope as separate named variables, it sometimes makes sense to access the whole argument and this can be done via __arg. function(x, y, i) { Run Karate Test. See also match header which is what you would normally need. all There is only one thing you need to do to switch the environment - which is to set a Java system property. karate-chrome. This is super-useful for re-use and data-driven tests. function (config, downloadLatestFn) { For advanced users, Karate supports being able to query for tags within a test, and even tags in a @name=value form. This is typically combined with multipart file as shown below. Mac: Cmd+R+1. The name of the class doesn't matter, and it will automatically run any *.feature file in the same package. In some cases where the response JSON is wildly dynamic, you may want to only check for the existence of some keys. This means that all your. You can then skip the next few sections, as the pom.xml, recommended directory structure, sample test and JUnit 5 runners - will be created for you. Linux: Ctrl+Shift+R+1. you can use pure JsonPath expressions (notice how this is different from the above), # and even append to json arrays (or create them automatically), # and for match - the order of keys does not matter, # you can ignore fields marked with '#ignore', # you can even set whole fragments of xml, """ You need to be familiar with Karate in order to understand the Calling Custome Java Code in Karate API Teststutorial. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. The primary classes are described below. data: { The syntax will include a = sign between the key and the value. [{ Also note that you dont use @Karate.Test for the method, and you just use the normal JUnit 5 @Test annotation. This is what is normally expected and simulates a web-browser - which makes it easy to script things like HTML-form based authentication into test-flows. This is technically not in the key-value form: multipart field name = 'foo', but logically belongs here in the documentation. Below is a simple example that will compare a baseline image to a more recent latest image. Custom header manipulation for every HTTP request is something that Karate makes very easy and pluggable. How to run a specific feature file in karate? ] In this file, we will write out the test scenarios that need to be executed for performing the API Testing. Heres how it works for XML: This comes in useful in some cases - and avoids needing to use the set keyword or JavaScript functions to manipulate JSON. Important: do not use the @RunWith(Karate.class) annotation. Although it is just a few lines of code, take time to study the above example carefully. Typically you would examine the value property as in the example above, but domain and path are also available. If you find yourself struggling to write dynamic JsonPath filters, look at karate.filter() as an alternative, described just below. a JSON array). For every HTTP request made from Karate, the internal flow is as follows: This makes setting up of complex authentication schemes for your test-flows really easy. Install Karate VS Code Plugin. Provides supports for the Data Driver Testing that is built in-house, hence no need to depend on external frameworks. A very useful capability is to be able to check that an array contains an object that contains the provided sub-set of keys instead of having to specify the complete JSON - which can get really cumbersome for large objects.
