karate run specific feature file
Soumendra Daas has created a nice example and guide that you can use as a reference here: hello-karate. This is a normal JUnit 4 test class ! The structure should be a def keyword followed by a variable name and a value. Create util.DbUtils java class and add the following java code snippet. You can perform database validations with karate by following the below steps. "b": 2, } The default is 30000 (30 seconds). But note that you can use the negative form of a tag selector: ~@region=GB. See also match header which is what you would normally need. For convenience, you can have multiple expressions separated by commas, so this is the recommended pattern: Similar to assert, the expressions on the right-hand-side of a print have to be valid JavaScript. If you want to dynamically and programmatically determine the tags and features to be included - the API also accepts. bottom: 893, Given this custom, user-defined Java class: This is how it can be called from a test-script via JavaScript, and yes, even static methods can be invoked: Note that JSON gets auto-converted to Map (or List) when making the cross-over to Java. But this does not limit you in any way, because similar to how you can call *.feature files, you can pass a whole JSON object as the argument. } But if you need to use values in the response headers - they will be in a variable named responseHeaders. Karate provides a far more simpler and more powerful way than JSON-schema to validate the structure of a given payload. # and even ignore fields at the same time ! There can be multiple Scenario-s in a *.feature file, and at least one should be present. Syntax highlighting should work right away and if you don't see something similar like in the following screenshot, make sure you have selected karate as . Karate has enhanced the Cucumber Scenario Outline as follows: These are best explained with examples. Create a new job using the +Add new job link. In this chapter, we will discuss memory coalescing. With this, we will execute our test cases in parallel format. var JavaDemo = Java.type('com.mycompany.JavaDemo'); The match keyword can be made to iterate over all elements in a JSON array using the each modifier. If you place it above the Feature keyword, it will apply to all Scenario-s. And if you just want one or two Scenario-s to NOT run in parallel, you can place this tag above only those Scenario-s. See example. If you use the above config, logs will be captured in target/karate.log. in just one extra line you can save the value of karate.prevRequest and pass it around. any valid JavaScript expression, and variables can be mixed in, another example: equivalent to the above, JavaScript function invocation, Pretty print the request payload JSON or XML with indenting (default, Pretty print the response payload JSON or XML with indenting (default. If you get stuck and ask a question on Stack Overflow, make sure you provide a cURL command that works - or else it would be very difficult for anyone to troubleshoot what you could be doing wrong. When JavaScript executes in Karate, the built-in karate object provides some commonly used utility functions. If you dont want to use Java, you have the option of just downloading and extracting the ZIP release. Note that the mvn test command only runs test classes that follow the *Test.java naming convention by default. 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. German or ISO-8859-15. If you want to use JUnit 4, use karate-junit4 instead of karate-junit5. convenient way to execute an OS specific command and return the console output e.g. Parallel testing is the core functionality that is provided by the Karate itself, hence we need not depend on Maven, Gradle, etc. Especially when payloads are complex (or highly dynamic), it may be more practical to use contains semantics. This is a very powerful way to generate test-data without having to load a large number of data rows into memory. Use a variable in the called feature instead, for e.g. 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. Add a runner Java class with Karate Junit 5 test. There are examples of calling JVM classes in the section on Java Interop and in the file-upload demo. We will use karate.properties [user.dir] which will automatically pick users working directory and then append it to the path of our project files. * header Authorization = call read('basic-auth.js') { username, # just perform an action, we don't care about saving the result, # do something only if a condition is true, # you can use multiple lines of JavaScript if needed, """ "hotels": [ 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. Also see the option below, where you can data-drive an Examples: table using JSON. Note how we unpack the kittens and use it to data drive the Scenario Outline. This is typically combined with multipart file as shown below. In some cases where the response JSON is wildly dynamic, you may want to only check for the existence of some keys. A very useful behavior when you combine the optional marker with an embedded expression is as follows: if the embedded expression evaluates to null - the JSON key (or XML element or attribute) will be deleted from the payload (the equivalent of remove). Here is an example of how to get the current date, and formatted the way you want: And the above will result in something like this being logged: [print] 2017/10/16. And you can perform conditional / cross-field validations and even business-logic validations at the same time. Here is an example: testCompile 'com.intuit.karate:karate-junit5:1.3.1', systemProperty "karate.options", System.properties.getProperty("karate.options"), systemProperty "karate.env", System.properties.getProperty("karate.env"), "ch.qos.logback.classic.filter.ThresholdFilter", // don't waste time waiting for a connection or if servers don't respond within 5 seconds, # steps here are executed before each Scenario in this file, # variables defined here will be 'global' to all scenarios, # and will be re-initialized before every scenario, # assigning a number (you can use '*' instead of Given / When / Then). var nums = [0, 1, 2, 3, 4]; It can also be argued that the # symbol is easy to spot when eyeballing your test scripts - which makes things more readable and clear. This is useful because the moment you use a wildcard [*] or search filter in JsonPath (see the next section), you get an array back - even though typically you would only be interested in the first item. get metadata about the currently executing feature within a test, functional-style filter operation useful to filter list-like objects (e.g. Note that if you tag Examples like this, and if a tag selector is used when running a given Feature - only the Examples that match the tag selector will be executed. response is a built-in variable in karate that stores HTTP API response. Otherwise they would be evaluated as expressions - which does come in useful for some dynamic data-driven situations: Yes, you can even nest chunks of JSON in tables, and things work as you would expect. Karate is an open-source API test automation tool. In typical frameworks it could mean changing multiple properties files, maven profiles and placeholders, and maybe even threading the value via a dependency-injection framework - before you can even access the value within your test. { you can use pure JsonPath expressions (notice how this is different from the above), # and even append to json arrays (or create them automatically), # and for match - the order of keys does not matter, # you can ignore fields marked with '#ignore', # you can even set whole fragments of xml, """ If you really need to re-use a Java function, see Java Function References. Karate API Test Script. Karate can run tests in parallel, and dramatically cut down execution time. Karate gives us lots of options to work with data. String interpolation will support variables in scope and / or the Examples (including functions defined globally, but not functions defined in the background). The following table summarizes some key differences between Cucumber and Karate. """, """ A handler function is needed only if you have to ignore some incoming traffic and stop the wait when a certain payload arrives. If you mix Karate into a Maven or Gradle project with many other dependendies, you may run into problems because of dependency conflicts.
