""", # attempt to detect and ignore antialiasing, # customize color / brightness tolerances, # switch to `original` grayscale SSIM algorithm, # JS math can introduce a decimal point in some cases, # but you can easily coerce to an integer if needed, # or you can do the same on multiple lines if you wish, # set headers or params (if any) BEFORE the method step. The syntax is easy to understand by non-programmers. Remove elements from a list in karate? Step 5: Now we can run this TestRunner class as JUnit. Note that Content-Type had to be enclosed in quotes in the JSON above because the - (hyphen character) would cause problems otherwise. var JavaDemo = Java.type('com.mycompany.JavaDemo'); Since paths are expected at the end of the command-line options - if you want to only over-ride tags, use the = sign to make argument values clear. height Use a variable in the called feature instead, for e.g. for example on a Mac you can use this command: it is recommended that you stick to these defaults, which should suffice for most applications, if you really want, you can change this globally in, even if the driver is instantiated (using the, you can route multiple URL patterns to the same Karate mock-feature, the format of each array-element under. Step 4: Run this feature file and get the report in target > karate-reports > karate-summary.html. """, "function(e){ return getComputedStyle(e)['font-size'] }", # this shorter version is equivalent to the above, # get text for all elements that match css selector, # now you can have multiple steps refer to "e", # find all elements with the text-content "Click Me", # perform some API calls and initialize the value of "token". When your project gets complex, you can have separate karate-config-.js files that will be processed for that specific value of karate.env. Each item within responseCookies is itself a map-like object. 1. Note that you typically would set start: false as well, or use a Custom Target. Since a scroll() + click() (or input()) is a common combination, you can chain these: This returns an instance of Mouse on which you can chain actions. Also see this explanation. The function argument is the row-index, so you can easily determine when to stop the generation of data. The most common use-case would be to partition your tests into smoke, regression and the like - which enables being able to selectively execute a sub-set of tests. And similarly - for specifying the HTTP proxy. What started as a powerful, scriptable framework combining API and UI test automation, is adopted as a best-practice today - in teams around the world. In rare cases you may want to suppress the default of Scenario-s executing in parallel and the special tag @parallel=false can be used. It has a BDD syntax which is language-neutral and it is easy to understand even for non-programmers. For convenience, some stats are logged to the console when execution completes, which should look something like this: The parallel runner will always run Feature-s in parallel. If you find yourself needing a complex helper or utility function, we strongly recommend that you use Java because it is much easier to maintain and even debug if needed. Note how we can even serve an image with the right Content-Type header. Note: desiredCapabilities has been deprecated and not recommended for use. if you are using Karate to create a Java application, LOGBack will look for logback.xml. Note that all the short-cut forms on the right-side of the table resolve to equality (==) matches, which enables them to be in-lined into a full (single-step) payload match, using embedded expressions. { By default, the value of karate.env when you access it within karate-config.js - would be null. Alternatively, if using Gradle then add the following sourceSets definition. In such cases, the function can do nothing or return an empty JSON. { Note that def can be used to assign a feature to a variable. Now you can use the path of the batch file in the driver executable config. Watch launch recording here. You can also sort arrays of arbitrary JSON using karate.sort(). Get method in HTTP is used to read or access data or information. For JSON, you can also use the JS delete operator via eval, useful when the path you are trying to mutate is dynamic. Note that the mvn test command only runs test classes that follow the *Test.java naming convention by default. Since the eval keyword can be omitted when operating on variables using JavaScript, this leads to very concise code: Refer to eval for more / advanced examples. The last boolean argument is whether the karate-config.js should be processed or not. But we recommend that you do this only if you are sure that these routines are needed in almost all *.feature files. ] It is also possible to invoke a feature file via a Java API which can be useful in some test-automation situations. 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>. So in dev mode you can easily set this behavior like this. Something like this: For HTTPS / SSL, you can also specify a custom certificate or trust store by setting Java system properties. By default, all actions such as click() will not be re-tried - and this is what you would stick to most of the time, for tests that run smoothly and quickly. : * param myparam = 'value' or url: * url 'http://example.com/v1?myparam'. If you are looking for ways to do something only once per feature or across all your tests, see Hooks. You can experiment for yourself (probably depending on the size of your test-automation team) if this leads to any appreciable benefits, because the down-side is that you need to keep switching between 2 files - when writing and maintaining tests. var results = innerText('.js-tree-browser-result-path'); Note that for. Karate Labs is an industry leading open-source test automation solution unifying API & UI test automation. There is no need to escape characters like you would have had to in Java or other programming languages. 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. The signal to stop the loop is to return any not-null object. 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. Use either the param keyword, e.g. But normally a match statement is preferred unless you want a really descriptive error message. Here is a recap of symbols that can be used in JSON embedded expressions: There is a shortcut for match each explained in the next section that can be quite useful, especially for in-line schema-like validations. API testing basics and Karate framework 2. Simple, clean syntax that is well suited for people new to programming or test-automation. It is worth internalizing that during test-execution, it is upon the method keyword that the actual HTTP request is issued. There is a neat way to tag your tests and the above example demonstrates how to run all tests except the ones tagged @skipme. If you really need to re-use a Java function, see Java Function References. Here are the few things you need to know. String interpolation will support variables in scope and / or the Examples (including functions defined globally, but not functions defined in the background). Here are the rules Karate uses on bootstrap (before every Scenario or Examples row in a Scenario Outline): Advanced users who build frameworks on top of Karate have the option to supply a karate-base.js file that Karate will look for on the classpath:. A very powerful variation of waitUntil() takes a full-fledged JavaScript function as the argument. Valid options are, Function to be called when displaying image comparison rebase in Karate HTML reports (e.g. If a handler function (returning a boolean) is provided - it will be used to complete the listen wait if true is returned. Sometimes, because of an HTTP re-direct, it can be difficult for Karate to detect a page URL change, or it will be detected too soon, causing your test to fail. 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. They are param, header, cookie, form field and multipart field. You would typically use these to simulate a user sign-in and then grab a security token from the response. Most of the time you will prefer the short-cut boolean-expression form that begins with an underscore (or !), and Karate will inject the JavaScript DOM element reference into a variable named _. Refer to the section on dynamic port numbers for an example. 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. See Chrome Java API. It will inject all top-level keys of the JSON file into the Karate context as global variables. }, The following method signatures are available on the karate JS object to obtain a websocket client: These will init a websocket client for the given url and optional subProtocol. The answer is no. With the above in place, you dont have to keep switching between your src/test/java and src/test/resources folders, you can have all your test-code and artifacts under src/test/java and everything will work as expected. This is super-useful for re-use and data-driven tests. Since templates can be loaded using the classpath: prefix, you can even re-use templates across your projects via Java JAR files. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. Emulating a device is supported natively only by type: chrome. The above example would save the file and perform auto-embedding into the HTML report. A common use case is to mix API-calls into a larger test-suite, for example a Selenium or WebDriver UI test. { And the right-hand-side can be any valid Karate expression. Assertions and HTML reports are built-in, and you can run tests in parallel for speed. See also responseStatus if you want to do some complex assertions against the HTTP status code. return jd.doWork(arg); 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. Finally, using karate.response.header(name) can be simpler to just get a header value string by name, and it will ignore-case for the name passed as the argument: You would normally only need to use the status keyword. API tests are written in BDD (Behaviour Driven Development) Using Gherkin syntax. It validates the entire payload in one step and checks if the kittens array contains all the expected items but in any order. It will default to { browserName: '' } for convenience where will be chrome, firefox etc. """, """ For convenience, non-existent keys (or array elements) will be created automatically. countryId: '#number', 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. When using Playwright you can omit this in which case Karate will default to Chrome (within Playwright) and the default browser window size. returns the last HTTP response as a JS object that enables advanced use-cases such as getting a header ignoring case: returns the last HTTP request as a JS object that enables advanced use-cases such as getting a header ignoring case: get metadata about the currently executing, sets the value of a variable (immediately), which may be needed in case any other routines (such as the, where the single argument is expected to be a, only needed when you need to conditionally build payload elements, especially XML. Karate will also run Scenario-s in parallel by default. status: '#number? Pay attention to the fact that the includes() function you see in the above example - is pure JavaScript. 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
