That said, if you want to stick to JavaScript, but find yourself accumulating a lot of helper functions that you need to use in multiple feature files, the following pattern is recommended. Note that Content-Type had to be enclosed in quotes in the JSON above because the - (hyphen character) would cause problems otherwise. when a string coming from an external process is dynamic - and whether it is JSON or XML is not known in advance, see, get the value of a variable by name (or JsonPath expression), if not found - this returns, returns only the keys of a map-like object, log to the same logger (and log file) being used by the parent process, logging can be suppressed with, access to the Karate logger directly and log in debug. But you can suffix a ?name to the feature to de-dupe it, like so: Now adminResponse and userResponse will be different, even though the same feature file is being used for a callSingle(). The results of the first call are cached, and any future calls will simply return the cached result instead of executing the JavaScript function (or feature) again and again. When you use Karate, all your data assertions can be done in pure JSON and without needing a thick forest of companion Java objects. Cucumber has a limitation where Background steps are re-run for every Scenario. In Karate - these are typically one-liners. for (var n in nums) { Karate also has a dedicated tag, and a very active and supportive community at Stack Overflow - where you can get support and ask questions. All we need to do now is to tell Chrome to intercept some URL patterns and use the above mock-server feature-file: The entire example can be found here - and here is a video. "arr": [ The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. If Chrome is not installed in the default location, you can pass a String argument like this: For more control or custom options, the start() method takes a Map argument where the following keys (all optional) are supported: Only supported for driver type chrome. Teams typically define complicated JSON (or XML) payloads in a file and then re-use this in multiple scripts. _ == _$.roomInformation[0].roomPrice' }, """ 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. = . Here are the few things you need to know. When a constant value keeps on repeating replace it with a variable. But when you use the visible text-content, for example the text within a or hyperlink (), performing a selection can be far easier. Though not really recommended, you can have multiple Scenario-s within a Feature tagged with @setup. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. You can use * char instead of Gherkin keyword. 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 /. Here is a good example in the demos: dynamic-params.feature, The single JSON argument needs to be in the form { field1: { read: 'file1.ext' }, field2: { read: 'file2.ext' } } where each nested JSON is in the form expected by multipart file. Pay attention to the fact that the includes() function you see in the above example - is pure JavaScript. 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. But take a look at how Karate can loop over a *.feature file for each object in a JSON array - which gives you dynamic data-driven testing, if you need it. 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. What we will do is intercept any request to a URL pattern *randomuser.me/* and fake a response. Best-practice would be to implement Hybrid Tests where the values for the auth-cookies are set only once for the whole test-suite using karate.callSingle(). Some XPath expressions return a list of nodes (instead of a single node). And if you need to view the container display via VNC, set the vncPort to map the port exposed by Docker. A common use case is to mix API-calls into a larger test-suite, for example a Selenium or WebDriver UI test. The syntax is easy to understand by non-programmers. And Karate gives you control over these aspects with the small set of keywords focused on HTTP such as url, path, param, etc. This means that all your. It is worth internalizing that during test-execution, it is upon the method keyword that the actual HTTP request is issued. Here is a real-life example combined with the use of retry(): If you have more than two locators you need to wait for, use the single-argument-as-array form, like this: Returns an Element (instead of exists() which returns a boolean). Multiple feature files (or paths) can be specified, de-limited by the space character. 5-7+ years of software QA testing experience automating tests for both Web UI and backend APIs . The solution is to ensure that when Karate tests run, the JVM file.encoding is set to UTF-8. You can even create (or modify existing) JSON arrays by using multiple columns. But when you deal with complex, nested JSON (or XML) - it may be easier in some cases to use replace, especially when you want to substitute multiple placeholders with one value, and when you dont need array manipulation. A few special built-in variables such as $ (which is a reference to the JSON root) - can be mixed into JSON embedded expressions. - Karate is BDD testing framework - Developer by Peter Thomas in 2017 (intuit). Instead of using call (or callonce) you are always free to call JavaScript functions normally and then you can use more than one argument. How To Scroll Into View in Selenium Webdriver, How To Solve IllegalStateException in Selenium WebDriver. Karate can run tests in parallel, and dramatically cut down execution time. Features API and UI automation Query Params: To filter/sort the resources from the server we used Query parameter. It is important to note that myFile above is the field name within the multipart/form-data request payload. Empty cells or expressions that evaluate to null will result in the key being omitted from the JSON. Learn more. Step 3: Add steps to run a sample POST API request. 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. If you use the Maven tweak described earlier (recommended), the root of the classpath will be in the src/test/java folder, or else would be src/test/resources. Note that the path resets after any HTTP request is made but not the url. For a call (or callonce) - payload / data structures (JSON, XML, Map-like or List-like) variables are passed by reference which means that steps within the called feature can update or mutate them, for e.g. Karate Framework for web automation. So especially when doing above() or below(), ensure that the search path is aligned the way you expect. You should be able to right-click and run a single method using your IDE - which should be sufficient when you are in development mode. So even if your next step is the ENTER key, you can do this: Karate will do the best it can to detect a page change and wait for the load to complete before proceeding to any step that follows. myInt + ''), in some rare cases, you may need to convert a string to a number. 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. And you can even handle asynchronous flows such as listening to message-queues. 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:. You can start a Driver instance programmatically and perform actions and assertions like this: You can find the complete example here. But you can choose a single test to run like this: When your Java test runner is linked to multiple feature files, which will be the case when you use the recommended parallel runner, you can narrow down your scope to a single feature, scenario or directory via the command-line, useful in dev-mode. object.name. Also refer to this demo example for a working example of multipart file uploads: upload.feature. Karate supports the following functional-style operations via the JS API - karate.map(), karate.filter() and karate.forEach(). You can call send() on the returned object to send a message. hero(name: "") { You can also compare images using Karate path prefixes (e.g. And steps that follow should logically be in the Then form. Note that Map translates to JSON, and JavaBean getters and setters translate to JS properties - e.g. This method returns a byte array. The usage of karate.write() here is just an example, you can use JS or Java interop as needed. If you want to dynamically and programmatically determine the tags and features to be included - the API also accepts. Keywords such as set and remove allow you to to tweak payload-data to fit the scenario under test. You may be able to turn this into a custom record-replay framework, or do other interesting things. If you are familiar with Cucumber (JVM), you may be wondering if you need to write step-definitions. The contents of my-signin.feature are shown below. Note that scriptAll() will return an array, as opposed to script(). But if you are really dealing with an HTML , then read on. 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 match keyword is explained later, but it should be clear right away how convenient the table keyword is. So you could have also done something like: Also refer to the configure keyword on how to switch on pretty-printing of all HTTP requests and responses. We recommend that you use the Karate extension for Visual Studio Code - and with that, JavaScript, .NET and Python programmers will feel right at home. You can even use a regular-expression so that instead of checking for equality, Karate will just validate that the actual value conforms to the expected pattern. Try this especially if you dont have much experience with programming or test-automation. 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. Just ensure that this is configured before you use karate.callSingle(): By default Karate will use target (or build) as the cache folder, which you can over-ride by adding a dir key: This caching behavior will work only if the result of karate.callSingle() is a JSON-like object, and any JS functions or Java objects mixed in will be lost. It will be initialized only after the driver keyword has been used to navigate to a web-page (or application). 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. 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. Refer to your IDE documentation for how to run a JUnit class. 3+ years Selenium, Cucumber, BDD, Gherkin Karate or RestAssured framework, Jenkins and SonarCube . Any valid XPath expression is allowed on the left-hand-side of a match statement. And also note that instead of using the match keyword, you can use karate.match() for very advanced conditional checks. Karate Test Automation Made Simple. If you are a Java developer - Karate requires at least Java 8 and then either Maven, Gradle, Eclipse or IntelliJ to be installed. While this sounds dangerous and should be used with care (and limits readability), the reason this feature exists is to quickly set (or over-write) a bunch of config variables when needed. Karate is the only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. Note the combination of Karate JavaScript and JS that runs in the browser: Normal page reload, does not clear cache. Also refer to the wiki for using Karate with Gradle. """, # normal 'equality' match. Also refer to the eval keyword for a simpler way to execute arbitrary JavaScript that can be useful in some situations. By default, the file is expected to be in the same folder (package) and side-by-side with the *.feature file. Note that you would typically want to use the @ignore tag for such cases. You can re-use the function you create across your whole project. Other UI automation frameworks spend a lot of time encouraging you to follow a so-called Page Object Model for your tests. You just need to do a normal POST (or GET). If you want to use JUnit 4, use the karate-junit4 Maven dependency instead of karate-junit5. There is no need to escape characters like you would have had to in Java or other programming languages. It can look something like this. But sometimes it is un-avoidable, for example to wait for animations to render - before taking a screenshot. You simply do something like this: A common need is to send the same header(s) for every request, and configure headers (with JSON) is how you can set this up once for all subsequent requests. But there is an elegant way you can specify a default value using the karate.get() API: A word of caution: we recommend that you should not over-use Karates capability of being able to re-use features. The JS API has a karate.signal(result) method that is useful for involving asynchronous flows into a test. Observe the usage of Scenario Outline: instead of Scenario:, and the new Examples: section. returns the operating system details as JSON, for e.g. subType: predicate syntax, and situations where this comes in useful will be apparent when we discuss match each. Here is an example of an implementation. Assertions and HTML reports are built-in, and you can run tests in parallel for speed. the NOT operator e.g. Test data can be within the main flow itself, which makes scripts highly readable. "a": 1, Name the file as javadsl.java and run using the command: jbang javadsl.java. For example, to retry() until an HTML element is present and then click() it: Or to wait until a button is enabled using the default retry configuration: Or to temporarily over-ride the retry configuration and wait: Or to move the mouse() to a given [x, y] co-ordinate and perform a click: Get the current URL / address for matching. Look at how the path did not need to be specified for the second HTTP get call since /cats is part of the url. In such cases, the function can do nothing or return an empty JSON. Important: If you attempt to build a URL in the form ?myparam=value by using path the ? And the JSON will still be well-formed, and editable in your IDE or text-editor. You can see a demo video here. Karate is a great fit for testing GraphQL because of how easy it is to deal with dynamic and deeply nested JSON responses. convenient way to execute an OS specific command and return the console output e.g. Refer to this case study for how dramatic the reduction of lines of code can be. for simulating check-boxes and multi-selects): You can also dynamically set multiple fields in one step using the form fields keyword. Typical symptoms are your tests working fine via the IDE but not when running via Maven or Gradle. 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. predicate marker to validate that the value of totalPrice is always equal to the roomPrice of the first item in the roomInformation array. Note the extra convenience where you dont have to enclose the LHS key in quotes. You can find a lot more references, tutorials and blog-posts in the wiki. 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. It so happens that the karate object has a field called properties which can read a Java system-property by name like this: karate.properties['myName'].
