As a convenience you can use the Chrome concrete implementation of a Driver directly, designed for common needs such as converting HTML to PDF - or taking a screenshot of a page. Note how even tags to exclude (or include) can be specified: Note that any Feature or Scenario with the special @ignore tag will be skipped by default. Also refer to the eval keyword for a simpler way to execute arbitrary JavaScript that can be useful in some situations. 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 path blog?page=2. Ping me Now! It will default to { browserName: '' } for convenience where will be chrome, firefox etc. Step 2: Add Cucumber plugin in Eclipse > Restart eclipse. Get all my courses for USD 5.99/Month - https://bit.ly/all-courses-subscriptionIn this Karate Tutorial, we will learn about webelement functions in Karate, l. 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. The first will simply return a List of Element instances. var results = innerText('.js-tree-browser-result-path'); This can be done via the maven-surefire-plugin configuration. The approach in this section is more suited for troubleshooting in dev-mode, using your IDE. What we will do is intercept any request to a URL pattern *randomuser.me/* and fake a response. stop(): Karate will call this method at the end of every top-level Scenario (that has not been call-ed by another Scenario). All arrays no matter the depth will be checked in this way. As mentioned above, most CI tools would be able to process the JUnit XML output of the parallel runner and determine the status of the build as well as generate reports. In rare cases you may need to set a variable from this routine, and a good example is to make the generated UUID visible to the currently executing script or feature. bar: 'world' 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. So if you really wanted to assert that the HTTP response body is well-formed JSON or XML you can do this: Very rarely used - but you can get the Java system-time (for the current response) at the point when the HTTP request was initiated (the value of System.currentTimeMillis()) which can be used for detailed logging or custom framework / stats calculations. There is no concept of a default where for e.g. This example actually calls into existing Java code, and being able to do this opens up a whole lot of possibilities. function fn(x){ return x + 1 }. Here is how to replace one placeholder at a time: Karate makes it really easy to substitute multiple placeholders in a single, readable step as follows: Note how strings have to be enclosed in quotes. Typically right-clicking on the file in the project browser or even within the editor view would bring up the Run as JUnit Test menu option. And any variables which are alive in the context can be used in this expression. You can replace the values of com.mycompany and myproject as per your needs. Look at multipart entity for an example. get metadata about the currently executing feature within a test, functional-style filter operation useful to filter list-like objects (e.g. Conditional logic is not recommended especially within test scripts because tests should be deterministic. Any Karate expression can be used in the cell expression, and you can even use Java-interop to use external data-sources such as a database. Ideally it should return pure JSON and note that you always get a deep clone of the cached result object. Here is the above example re-written to do so: The result of karate.setup() will be a JSON of all the variables created within the Scenario tagged with @setup. Simple, clean syntax that is well suited for people new to programming or test-automation. Also note that locate() and locateAll() can be called on an Element, so that the search scope is limited to that Element and its children. It is important to note that myFile above is the field name within the multipart/form-data request payload. It is based on Cucumber and uses the Gherkin Syntax. 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. So if you have a Feature with multiple Scenario-s in it - they will execute in parallel, and even each Examples row in a Scenario Outline will do so ! The section on Karate Expressions goes into the details. ] 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. One limitation is that you cannot use double-quotes within these expressions, so stick to the pattern seen below. It is sometimes useful to be able to check if a key-value-pair does not exist. Here is an example: Any Karate variable will be available to the template, which is users.html in this example. If you use * as the urlPattern every request can be routed to the mock ! Any valid XPath expression is allowed on the left-hand-side of a match statement. Uses the configured highlightDuration. Headers: In this section we can defined additional details of API to process the request. When using a browser-driver, a call in shared scope has to be used. The standard locator syntax is supported. } This is preferred because it takes care of situations such as if the value is undefined in JavaScript. Karate is the open source tool to combine API test automation, mockery, performance testing and even UI automation into a single framework. They use JSON to build the relevant parts of the HTTP request. And if being called in a loop, a built-in variable called __loop will also be available that will hold the value of the current loop index. karate.appendTo(keys, x); Note that waitForUrl() will also act as an assertion, so you dont have to do an extra match. You can do this by multiplying by 1 or using the built-in JavaScript parseInt() function: As per the JSON spec, all numeric values are treated as doubles, so for integers - it really doesnt matter if there is a decimal point or not. """, * configure imageComparison = { onShowRebase, # custom JS function called in Karate HTML image comparison UI when the user clicks the `Show config` button, """ 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. """, # note the 'text' keyword instead of 'def', """ We configure cors = true to ensure that the browser does not complain about cross-origin requests. Karate creates a new context for the feature file being invoked but passes along all variables and configuration. Sending a file as the entire binary request body is easy (note that multipart is different): The HTTP verb - get, post, put, delete, patch, options, head, connect, trace. """, """ And then you would use the built-in driver JS object for all other operations, combined with Karates match syntax for assertions where needed. id: 1 The Element API has getters for the following properties: This can be convenient in some cases, for example as an alternative to Friendly Locators. Below are the capabilities of Karate UI. Note that the path resets after any HTTP request is made but not the url. If a handler function (returning a boolean) is provided - it will be used to complete the listen wait if true is returned. To create paginated pdf document from the page loaded. A header row is always expected. } This is typically used for the first element you need to interact with on a freshly loaded page. The integer port argument is mandatory and you have to choose one that is not being used. Important: do not use the @RunWith(Karate.class) annotation. For tests that need to wait for slow pages or deal with un-predictable element load-times or state / visibility changes, Karate allows you to temporarily tweak the internal retry settings. This is designed specifically for the kind of situation described in the example for waitForAny(). Each array element is expected to be a JSON object, and for each object - the behavior will be as described above. You can over-ride it by using the header keyword before the method step. There are examples of calling JVM classes in the section on Java Interop and in the file-upload demo. The function argument is the row-index, so you can easily determine when to stop the generation of data. Make sure that the batch file is made executable depending on your OS. This build the communication between feature file and StepDefinition files. useful to scrape text out of non-JSON or non-XML text sources such as HTML, like the above, but returns a list of text-matches. Normally we recommend that you keep your re-usable features lightweight - by limiting them to just one Scenario. And most importantly - you can run tests in parallel without having to depend on third-party hacks that introduce code-generation and config bloat into your pom.xml or build.gradle. And thats all there is to Karate configuration ! a IMPORTANT: There are some restrictions when using callonce or karate.callSingle() especially within karate-config.js. Before we get to the HTTP keywords, it is worth doing a recap of the various shapes that the right-hand-side of an assignment statement can take: They are url, path, request, method and status. 'test1.feature', * def result = responseStatus == 404 ? The name of the class doesnt matter, and it will automatically run any *.feature file in the same package. Note that the karate-config.js is re-processed for every Scenario and in rare cases, you may want to initialize (e.g. This is just a convenience short-cut for waitUntil(locator, "_.textContent.includes('" + expected + "')") since it is so frequently needed. And this example may make it clear why using Karate itself to drive even your UI-tests may be a good idea. Modifying existing JSON and XML is natively supported by Karate via the set keyword, and replace is primarily intended for dealing with raw strings. If you want to use JUnit 4, use karate-junit4 instead of karate-junit5. Step 2: Add feature and scenario description. You can set this up for all subsequent requests or dynamically generate headers for each HTTP request if you configure headers. "b": 2, Read the documentation of the stand-alone JAR for more - such as how you can even install custom command-line applications using jbang ! This does require you to move set-up into a separate *.feature (or JavaScript) file. # we compose a function using another function (the one above), """ Karate is an open-source framework for API Test automation that uses BDD style syntax, has a rich assertion library, built-in HTML reports. Heres a simple recipe to set up this mechanism on your local machine. The recommendation is that you prefer chrome for development, and once you have the tests running smoothly - you can switch to a different WebDriver implementation. Observe the usage of Scenario Outline: instead of Scenario:, and the new Examples: section. This gives you some powerful options, for example you can simulate Ajax and XHR failures, or even replace entire widgets or sections of the page with fake HTML. Features API and UI automation Final word, Bookmark this post Karate Frameworkfor future reference. The business of web-services testing requires access to low-level aspects such as HTTP headers, URL-paths, query-parameters, complex JSON or XML payloads and response-codes. Karate provides an elegant native-like experience for placeholder substitution within strings or text content. 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 ! You could always do this in two steps: As a convenience, embedded expressions are supported on the Right Hand Side of a match statement even for quoted string literals: And do note that in Karate 1.0 onwards, ES6 string-interpolation within backticks is supported: An alternative to embedded expressions (for JSON only) is to enclose the entire payload within parentheses - which tells Karate to evaluate it as pure JavaScript. JavaScript Functions are also native. One example of when you may want to convert JSON (or XML) to a string is when you are passing a payload to custom code via Java interop. var results = scriptAll('.js-tree-browser-result-path', '_.innerText'); In the case of the call of a JavaScript function, you can also pass a JSON array or a primitive (string, number, boolean) as the solitary argument, and the function implementation is expected to handle whatever is passed. """, """ 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. The recommended approach for Karate reporting in a Continuous Integration set-up is described in the next section which can generate the JUnit XML format that most CI tools can consume. Here is an example: binary.feature. Karate has an elegant approach to handling any action such as click() that results in a new page load. And yes, you can use variable expressions from karate-config.js. For example: And similarly for XML and XPath, / represents the response. In case you were wondering, variables (and even expressions) are supported on the right-hand-side. """, Then match each json.hotels contains { totalPrice, #? JSON arrays), see, convenient for the common case of transforming an array of primitives into an array of objects, see, useful to merge the key-values of two (or more) JSON (or map-like) objects, see. 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:. The method signature of the assertTrue has flipped around a bit. can be specified like this: A special variable called Key will be available and you can see all the possible key codes here. Behaves the same way as the. Here is an example of using the call keyword to invoke another feature file, loaded using the read function: If you find this hard to understand at first, try looking at this set of examples. You could use it for hard-coded absolute paths in dev mode, but is obviously not recommended for CI test-suites. This is convenient for complex nested payloads where you are sure that you only want to check for some values in the various trees of data. How To Scroll Into View in Selenium Webdriver, How To Solve IllegalStateException in Selenium WebDriver. It can look something like this. Now we will create a scenario in feature file. locateAll() can take a second argument which has to be a JavaScript predicate function, that returns a boolean true or false. This also works as a getter to get the current window dimensions. And you can have a nested heirarchy, which means you can neatly name-space your locator reference look-ups - as you will see later below. To make dynamic data-driven testing easier, the following keywords also exist: params, headers, cookies and form fields. The Maven tradition is to have non-Java source files in a separate src/test/resources folder structure - but we recommend that you keep them side-by-side with your *.java files. Karate is even able to ignore fields you choose - which is very useful when you want to handle server-side dynamically generated fields such as UUID-s, time-stamps, security-tokens and the like. The demo also features code-coverage using Jacoco, and some tips for even non-Java back-ends. You may face issues if you attempt to mix in JS functions or Java code. In below image in get demo 4 scenario I have added few assertions. However, unlike Cucumber, tests aren't written in Java and are fully described in the Gherkin file. sportName: '#string', They are param, header, cookie, form field and multipart field. GET Example 2: In the Given section we are using path/query parameter. Cucumber has a concept of Scenario Outlines where you can re-use a set of data-driven steps and assertions, and the data can be declared in a very user-friendly fashion.
