If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. Karate is the only open-source tool to combine API test-automation, mocks and performance-testing into a single , unified framework. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers.
You can easily build or re-use complex request payloads, and dynamically construct more requests from response data. The payload and schema validation engine can perform a 'smart compare' deep-equals of two JSON or XML documents, and you can even ignore dynamic values where needed. Test execution and report generation feels like any standard Java project.
But there's also a stand-alone executable for teams not comfortable with Java. It is worth pointing out that JSON is a 'first class citizen' of the syntax such that you can express payload and expected data without having to use double-quotes and without having to enclose JSON field names in quotes. There is no need to 'escape' characters like you would have had to in Java or other programming languages. And you don't need to create additional Java classes for any of the payloads that you need to work with.
A set of real-life examples can be found here: Karate Demos. You can find a lot more references in the wiki. Karate also has its own 'tag' and a very active and supportive community at Stack Overflow. Karate requires Java 8 at least version 1. And if you run into class-loading conflicts, for example if an older version of the Apache libraries are being used within your project - then use karate-jersey instead of karate-apache.
If you want to use JUnit 5 , use karate-junit5 instead of karate-junit4. It may be easier for you to use the Karate Maven archetype to create a skeleton project with one command. You can then skip the next few sections, as the pom. If you are behind a corporate proxy, or especially if your local Maven installation has been configured to point to a repository within your local network, the command below may not work.
One workaround is to temporarily disable or rename your Maven settings. You can replace the values of com. You can also try using Karate as a stand-alone executable which is a good option if you have difficulties with the above process, or if you are not comfortable with Maven or Java. You can refer to this nice blog post and video by Joe Colantonio which provides step by step instructions on how to get started using Eclipse without having to run the command above.
Use the latest available version of Karate refer to the archetypeVersion above , and also make sure you install the Cucumber-Eclipse plugin! Another blog post which is a good step-by-step reference is this one by Micha Kops - especially if you use the 'default' maven folder structure instead of the one recommended below. A Karate test script has the file extension. You are free to organize your files using regular Java package conventions. When you have a large and complex project, you will end up with a few data files e.
This is very common in the world of Maven users and keep in mind that these are tests and not production code. Since these are tests and not production Java code, you don't need to be bound by the com. We suggest that you have a folder hierarchy only one or two levels deep - where the folder names clearly identify which 'resource', 'entity' or API is the web-service under test. Assuming you use JUnit, there are some good reasons for the recommended best practice naming convention and choice of file-placement shown above:.
Many popular text editors such as Visual Studio Code have support for the Gherkin syntax. It provides syntax coloring, and the best part is that you can 'right-click' and run Karate test scripts without needing to write a single line of Java code. If you are using the free Community Edition , you can easily install the "Gherkin" and "Cucumber for Java" plugins.
In some cases, for large payloads and especially when the default system encoding is not UTF-8 Windows or non-US locales , you may run into issues where a java. ByteArrayInputStream is encountered instead of a string. Other errors could be a java. URISyntaxException and match not working as expected because of special or foreign characters, e. German or ISO The solution is to ensure that when Karate tests run, the JVM file. This can be done via the maven-surefire-plugin configuration. 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.
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. For example if you have the JUnit class in the com. This is one reason why you may want to prefer a 'flat' directory structure as explained above. Karate supports JUnit 5 and the advantage is that you can have multiple methods in a test-class. Only one import is needed, and instead of a class-level annotation, you use a nice DRY and fluent-api to express which tests and tags you want to use.
Note that the Java class does not need to be public and even the test methods do not need to be public - so tests end up being very concise. Here is an example:. You can easily select double-click , copy and paste this file: URL into your browser address bar. This report is useful for troubleshooting and debugging a test because all requests and responses are shown in-line with the steps, along with error messages and the output of print statements.
Just re-fresh your browser window if you re-run the test. The JUnit 5 support does not require a class-level annotation to specify the feature s and tags to use. The features parameter in the annotation can take an array, so if you wanted to associate multiple feature files with a JUnit 4 test, you could do this:. You can even point to a directory or package. Combine this with tags to execute multiple features, without having to list every one of them.
When you have a 'runner' class in place, it would be possible to run it from the command-line as well. 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 or even directory via the command-line, useful in dev-mode.
Note how even tags to exclude or include can be specified using the Karate options. Multiple feature files or paths can be specified, de-limited by the space character. They should be at the end of the karate. For gradle you must extend the test task to allow the karate. To do that, add the following:. The recommended way to define and run test-suites and reporting in Karate is to use the parallel runner , described in the next section. The approach in this section is more suited for troubleshooting in dev-mode, using your IDE.
So if you take the previous folder structure example , you can do this on the command-line:. There is a neat way to tag your tests and the above example demonstrates how to run all tests except the ones tagged ignore. For JUnit 4, The tag options can be specified in the test-class via the KarateOptions annotation, in which case you don't need to pass the -Dkarate.
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 here would over-ride corresponding options specified if a KarateOptions annotation is present on AnimalsTest. The big drawback of the approach above is that you cannot run tests in parallel.
The recommended approach for Karate reporting in a Continuous Integration set-up is described in the next section which focuses on generating the JUnit XML format that most CI tools can consume. The Cucumber JSON format is also emitted, which gives you plenty of options for generating pretty reports using third-party maven plugins. 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.
Karate can run tests in parallel, and dramatically cut down execution time. This is a 'core' feature and does not depend on JUnit, Maven or Gradle. This is a normal JUnit 4 test class! The parallel runner will always run Feature -s in parallel. Karate will also run Scenario -s in parallel by default. 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 parallel runner will output a timeline. If you place it above the Feature keyword, it will apply to all Scenario -s but you just want one or two Scenario -s to NOT run in parallel, you can place this tag on only those Scenario -s. See example. There is also an API to run a chosen set of features and tags which may be useful in cases where you dynamically want to select features at run time.
Refer to this example DemoTestSelected. 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. The Karate Demo has a working example of the recommended parallel-runner set up. It also details how a third-party library can be easily used to generate some very nice-looking reports, from the JSON output of the parallel runner.
For example, here below is an actual report generated by the cucumber-reporting open-source library. This report is recommended especially because Karate's integration includes the HTTP request and response logs in-line with the test report , which is extremely useful for troubleshooting test failures. The demo also features code-coverage using Jacoco.
