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. German or ISO-8859-15. For example, see the sayHelloFactory() method below: And now, to get a reference to that function you can do this: This can be convenient when using shared scope because you can just call sayHello('myname') where needed. Here are some example assertions performed while scraping a list of child elements out of the JSON below. Karate provides a far more simpler and more powerful way than JSON-schema to validate the structure of a given payload. The Karate Demo has a working example of the recommended parallel-runner set up. You can even mix this into mouse() actions. The following table summarizes some key differences between Cucumber and Karate. In addition to fields, field may either be on the right or below the label depending on whether the container element had enough width to fit both on the same horizontal line. See waitForUrl() instead of submit(). Important: If you attempt to build a URL in the form ?myparam=value by using path the ? The advantage of this approach is that it works with any of the actions. A Karate test script has the file extension .feature which is the standard followed by Cucumber. The demo also features code-coverage using Jacoco, and some tips for even non-Java back-ends. More examples of Java interop and how to invoke custom code can be found in the section on Calling Java. Here are some examples: Take a look at how to loop and transform data for more ideas. And as a testing framework, Karate discourages tests that give different results on every run. 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. 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. 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. This will wait until the element (by locator) is present in the page and uses the configured retry() settings. One extra convenience for JSON is that if the variable itself (which was cat in the above example) does not exist, it will be created automatically. Also note that ; charset=UTF-8 would be appended to the Content-Type header that Karate sends by default, and in some rare cases, you may need to suppress this behavior completely. Cucumber has a limitation where Background steps are re-run for every Scenario. 1 [karate]: Karate UI Automation: Unable to launch the browser. For some more examples check test-outline-name-js.feature. 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. This capability is triggered when the table consists of a single cell, i.e. Ideally you should return only pure JSON data (or a primitive string, number etc.). Even though Wikipedia says "web-API", it can do web UI . The unified use of Karate test-doubles means that you can script dynamic responses and handle incoming URL, query-string and header variations. Note that embedded expressions will be evaluated even when you read() from a JSON or XML file. This example actually calls into existing Java code, and being able to do this opens up a whole lot of possibilities. Step 2: Add feature and scenario description. Normally we recommend that you keep your re-usable features lightweight - by limiting them to just one Scenario. This is super-useful for re-use and data-driven tests. To use Playwright, you need to start a Playwright server. When your project gets complex, you can have separate karate-config-.js files that will be processed for that specific value of karate.env. You just need to do a normal POST (or GET). bar: 'world' So instead of doing this: You should prefer this form, which is more readable: Note that to navigate to a new address you can use driver - which is more concise. The recipe for doing this when running Maven from the command line is: You can refer to the documentation of the Maven Surefire Plugin for alternate ways of achieving this, but the argLine approach is the simplest and should be more than sufficient for your Continuous Integration or test-automation needs. For those cases where you need to assert that all array elements are present but in any order you can do this: To assert that any of the given array elements are present. Navigates to a new page / address. The Runner.Builder API has a dryRun() method to switch this on. This will give you the usual HTML report showing what features will be run, including all steps shown (including comments) so that it can be reviewed. Technology Partner For example instead of: When it comes to JavaBean getters and setters, you could call them directly, but the driver.propertyName form is much better to read, and you save the trouble of typing out round brackets. Karate has a very useful payload templating approach. The get keyword allows you to save the results of a JsonPath expression for later use - which is especially useful for dynamic data-driven testing. If you are looking for a way to do something only once per Feature, take a look at callonce. On the other hand, if you are expecting a variable in the Background to be modified by one Scenario so that later ones can see the updated value - that is not how you should think of them, and you should combine your flow into one scenario. You need to call a method on the driver object directly: The example below has the width, height and userAgent for an iPhone X. """, * configure imageComparison = { onShowConfig, # don't embed the image comparison UI when the latest image is the same / similar to the baseline (e.g. }, This can be a huge time-saver ! You can also pass parameters into the *.feature file being called, and extract variables out of the invocation result. This is a good time to deep-dive into JsonPath, which is perfect for slicing and dicing JSON into manageable chunks. Modifying existing JSON and XML is natively supported by Karate via the set keyword, and replace is primarily intended for dealing with raw strings. all the key-value pairs are added to the HTTP headers. The signal to stop the loop is to return any not-null object. One way to define test-suites in Karate is to have a JUnit class at a level above (in terms of folder hierarchy) all the *.feature files in your project. Here is one suggested pattern you can adopt. And if you use the following mock, it will actually act as a pass-through proxy - but with the advantage that every single request and response will be emitted to target/karate.log. The karate-demo has an example showing various ways to configure or set headers: headers.feature. It will also return a string which is the actual URL in case you need to use it for further actions in the test script. Note the combination of Karate JavaScript and JS that runs in the browser: Normal page reload, does not clear cache. But this totally makes sense for things not part of the main test flow and which typically need to be re-usable anyway. The Background is optional. A very powerful variation of waitUntil() takes a full-fledged JavaScript function as the argument. Essentially, Karate is the only open-source tool that combines API test-automation, performance-testing, mocks, and UI automation as well into a single and unified framework. Since this is a frequently asked question, the different ways of being able to re-use code (or data) are summarized below. """, # optional (can be null) and if present should be an array of size greater than zero, # should be an array of size equal to $.count, # use a predicate function to validate each array element, # if you prefer using 'pure' JsonPath, you can do this, # using the karate object if the expression is dynamic, """ If you really need to have an empty body, you can use an empty string as shown below, and you can force the right Content-Type header by using the header keyword. The above would result in a URL like: http://myhost/mypath?someKey=hello&anotherKey=foo. 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. This is so that you can mix expressions into text replacements as shown below. This is typically combined with multipart file as shown below. And match (name) contains is how you can do so: Note that match contains will not recurse any nested JSON chunks so use match contains deep instead. 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. Note that any cookies returned in the HTTP response would be automatically set for any future requests. Note how we can even serve an image with the right Content-Type header. So you have the following type markers you can use instead of def (or the rarely used text). Read the documentation of the stand-alone JAR for more - such as how you can even install custom command-line applications using jbang ! As a convenience, there is a second form where you can pass an array as the second argument: And an extra convenience third argument is a time-delay (in milliseconds) that will be applied before each array value. Comprehensive support for different flavors of HTTP calls: You can easily choose features and tags to run and compose test-suites in a very flexible manner. function(s) { Embedded expressions also make more sense in validation and schema-like short-cut situations. Although rarely needed, variable references or expressions are also supported: This is a shortcut to assert the HTTP response code. countryName: '#string', physics To define Karate DSL, in simple words, we can say that it is a blend of API test-automation, mocks and performance-testing with UI-testing into a single, unified framework. Karate Labs is an industry leading open-source test automation solution unifying API & UI test automation. So if you tried to re-use the same feature but with multiple arguments, things will not work as you expect. All the fuzzy matching markers will work in XML as well. } Karate has the following short-cut symbols designed to be mixed into embedded expressions: For completeness, == and != also belong in the above list. if so, is the configured value a JavaScript function ? If you are a Java developer - Karate requires at least Java 8 and then either Maven, Gradle, Eclipse or IntelliJ to be installed. Pay attention to the fact that the includes() function you see in the above example - is pure JavaScript. So if you take the previous folder structure example, you can do this on the command-line: Here, AnimalsTest is the name of the Java class we designated to run the multiple *.feature files that make up your test-suite. You can also use JSON to set multiple query-parameters in one-line using params and this is especially useful for dynamic data-driven testing. But use wisely, because called scripts will now over-write variables that may have been already defined. By using this plugin, you agree to our privacy-policy. 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". Like above, but force the SSL algorithm to one of, Whether the HTTP client automatically follows redirects - (default, Set the connect timeout (milliseconds). 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. @smoke @module=one @module=two etc. One indicator of a good automation framework is how much work a developer needs to do in order to perform any automation action - such as clicking a button, or retrieving the value of some HTML object / property. 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. downloadLatestFn('custom_latest.png') For example: And similarly for XML and XPath, / represents the response. Now we will create a scenario in feature file. Yes, you can modify the request or response if needed ! return sdf.format(date); When targeting a W3C WebDriver implementation, either as a local executable or Remote WebDriver, you can specify the JSON that will be passed as the payload to the Create Session API. When handling XML, you sometimes need to call XPath functions, for example to get the count of a node-set. So how can you get this value injected into the Karate configuration ? This is preferred because it takes care of situations such as if the value is undefined in JavaScript. Karate supports JUnit 5 and the advantage is that you can have multiple methods in a test-class. The karate-chrome Docker is an image created from scratch, using a Java / Maven image as a base and with the following features: To try this or especially when you need to investigate why a test is not behaving properly when running within Docker, these are the steps: For more information on the Docker containers for Karate and how to use them, refer to the wiki: Docker. If your XPath is dynamic and has to be formed on the fly perhaps by using some variable derived from previous steps, you can use the karate.xmlPath() helper: You can refer to this file (which is part of the Karate test-suite) for more XML examples: xml-and-xpath.feature. After run TestRunner class, we can see Junit console report. For example, where it is easy (or you already have a reference) to locate some element and you want to use that as a base to perform something on some other element which may not have a unique id or css / XPath locator. 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. Even Java interop and access to the karate JS API would work. This means: Where login.feature would look something like: There are many ways to parameterize the driver config or perform environment-switching, read this for more details. If you have trouble with
