{ "roomInformation": [{ "roomPrice": 618.4 }], "totalPrice": 618.4 }, 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. Now we can right click on feature file and run it. using the set keyword. This is really convenient in dev-local mode. If you want to dynamically and programmatically determine the tags and features to be included - the API also accepts. The wildcard locators are great when the human-facing visible text is within the HTML element that you want to interact with. function() { Do note that if you prefer a pure Java API - Karate has that covered, and with far more capabilities. And you can consider a driverTarget approach for complex needs such as using a Docker container for CI. When you are in a hurry, you can pause a test in the middle of a flow just to look at the browser developer tools to see what CSS selectors you need to use. You can see what the result looks like here. That said, if you really need to implement conditional checks, this can be one pattern: And this is another, using karate.call(). Karate is the only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. And you can mix API and UI test-automation within the same test script. if you want to conditionally stop a test with a descriptive error message, e.g. This is super-useful when you need to wait for say a table of slow-loading results, and where the table may contain fewer elements at first. Of course it is an option to have Karate tests in a separate stand-alone maven project and folder, while still being in the same Git repository. The above example would save the file and perform auto-embedding into the HTML report. There are two forms. Karate, created by Intuit a few years ago, has matured into a stable tool with unique functionality. Notice how once the authToken variable is initialized, it is used by the above function to generate headers for every HTTP call made as part of the test flow. Since this is a frequently asked question, the different ways of being able to re-use code (or data) are summarized below. if so, is the configured value a JavaScript function ? Refer to the section on dynamic port numbers for an example. return sdf.format(date); For example: So this is just for convenience and readability, using configure driver can do the same thing like this: This design is so that you can use (and data-drive) all the capabilities supported by the target driver - which can vary a lot depending on whether it is local, remote, for desktop or mobile etc. {}, """ predicate marker to validate that the value of totalPrice is always equal to the roomPrice of the first item in the roomInformation array. As a convenience, you can call a tag directly, which is a short-cut to call another Scenario within the same feature file. This is perfect for those cases where it really doesnt make sense - for example the Background section or when you use the def or set syntax. That said, the syntax is very concise, and the convention of every step having to start with either Given, And, When or Then, makes things very readable. An image comparison UI will also be embedded into the Karate HTML report with detailed information about any differences between the two images. Normally an undefined variable results in nasty JavaScript errors. When using call (or callonce), only one argument is allowed. var sdf = new SimpleDateFormat('yyyy/MM/dd'); 2. _ > 0' }, # when validation logic is an 'equality' check, an embedded expression works better, Then match temperature contains { fahrenheit, # when the response is binary (byte-array), # incidentally, match and assert behave exactly the same way for strings, # if b can be present (optional) but should always be null, """ The steps which are defined under background will run before each and every scenario for a feature file. This will also do automatically perform a karate.embed() - so that the image appears in the HTML report. Or - if a call is made without an assignment, and if the function returns a map-like object, it will add each key-value pair returned as a new variable into the execution context. A great example of how you can extend Karate, even bypass the HTTP client but still use Karates test-automation effectively, is this gRPC example by @thinkerou: karate-grpc. Can be expressions that will be evaluated. But note that you can use the negative form of a tag selector: ~@region=GB. # but karate allows you to traverse xml like json !! Here is a summary: Note that for the afterFeature hook to work, you should be using the Runner API and not the JUnit runner. A working example of calling a SOAP service can be found within the Karate project test-suite. Other errors could be a java.net.URISyntaxException and match not working as expected because of special or foreign characters, e.g. Calling any Java code is that easy. You can even create (or modify existing) JSON arrays by using multiple columns. * url myUrl. 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 example if you have the JUnit class in the com.mycompany package, *.feature files in com.mycompany.foo and com.mycompany.bar will also be run. The documentation on how to run tests via the command line has an example of how to use tags to decide which tests to not run (or ignore). Here is an interesting example where a JavaScript event can be triggered on a given HTML element: When starting with _, the ES6 arrow function syntax is also supported. Also take a look at how a special case of embedded-expressions can remove key-value pairs from a JSON (or XML) payload: Remove if Null. You can change the com.intuit.karate logger level to INFO to reduce the amount of logging. Headers: In this section we can defined additional details of API to process the request. id: 1, """, # very useful for validating a response against a schema "super-set", * match karate.filterKeys(response, 'b', 'c') == { c, * match karate.filterKeys(response, ['a', 'b']) == { a, # generate a range of numbers as a json array, """ math returns the operating system details as JSON, for e.g. Here are some example assertions performed while scraping a list of child elements out of the JSON below. 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, """ Here is an example of waiting for a search box to appear after a click(), and note how we re-use the Element reference returned by waitFor() to proceed with the flow. Teams typically define complicated JSON (or XML) payloads in a file and then re-use this in multiple scripts. Hello World Index Capabilities Simple, clean syntax that is well suited for people new to programming or test-automation All-in-one framework that includes parallel-execution, HTML reports, environment-switching, and CI integration You can lock down the fact that you only want to execute the single JUnit class that functions as a test-suite - by using the following maven-surefire-plugin configuration: Note how the karate.options can be specified using the configuration. This is useful when you want to express a one-off lengthy snippet of text in-line, without having to split it out into a separate file. 1. To use the recommended --security-opt seccomp=chrome.json Docker option, add a secComp property to the driverTarget configuration. Although it is just a few lines of code, take time to study the above example carefully. Now we will create a scenario in feature file. a named JsonPath or XPath expression - e.g. To avoid flaky tests, use waitForUrl(). For example, here below is an actual report generated by the cucumber-reporting open-source library. It short-cuts to the pre-defined variable responseHeaders and reduces some complexity - because strictly, HTTP headers are a multi-valued map or a map of lists - the Java-speak equivalent being Map>. The final piece of the puzzle is to set up a batch file to start the server: The exec is important here so that Karate can stop the node process cleanly. You would typically use these to simulate a user sign-in and then grab a security token from the response. So you can use Karate to set-up data via API calls, then run the UI test-automation, and finally again use Karate to assert that the system-state is as expected. Also see the option below, where you can data-drive an Examples: table using JSON. To signal the end of the data, just return null. In such cases, you can always fall-back to a waitForUrl() or a more generic waitFor(). Karate is a great fit for testing GraphQL because of how easy it is to deal with dynamic and deeply nested JSON responses. . And it is used to create a variable. Here are the configuration keys supported: If you need to set any of these globally you can easily do so using the karate object in karate-config.js - for e.g: In rare cases where you need to add nested non-JSON data to the configure value, you have to play by the rules that apply within karate-config.js. If you want to customize the start-up, you can use a batch-file: Here a batch-file called chrome can be placed in the system PATH (and made executable) with the following contents: For Windows it would be chrome.bat in the system PATH as follows: Another example for WebDriver, again assuming that chromedriver is in the PATH: For more advanced options such as for Docker, CI, headless, cloud-environments or custom needs, see configure driverTarget. You can find more JSON examples here: js-arrays.feature. There are 2 variants, one that takes an integer as the param, in which case the frame is selected based on the order of appearance in the page: Or you use a locator that points to the
