karate run specific feature file

Even Java interop and access to the karate JS API would work. Comma delimited values are supported which can be more convenient, and takes care of URL-encoding and appending / between path segments as needed. If you want to use JUnit 4, use the karate-junit4 Maven dependency instead of karate-junit5. Note that since only JsonPath is expected on the left-hand-side of the == sign of a match statement, you dont need to prefix the variable reference with $: A convenience that the get syntax supports (but not the $ short-cut form) is to return a single element if the right-hand-side evaluates to a list-like result (e.g. For a detailed discussion on BDD and how Karate relates to Cucumber, please refer to this blog-post: Yes, Karate is not true BDD. $ represents the response. if you are using Karate to create a Java application, LOGBack will look for logback.xml. ] Also note that you dont use @Karate.Test for the method, and you just use the normal JUnit 5 @Test annotation. The match keyword can be made to iterate over all elements in a JSON array using the each modifier. There is also a variant of Scenario called Scenario Outline along with Examples, useful for data-driven tests. "b": 2, And each element of the returned array will be the envelope of variables that resulted from each iteration where the *.feature got invoked. } But we recommend that you do this only if you are sure that these routines are needed in almost all *.feature files. { return a pretty-printed, nicely indented string representation of the JSON value, also see: return a pretty-printed, nicely indented string representation of the XML value, also see: get the value of any Java system-property by name, useful for, returns a JSON array of integers (inclusive), the optional third argument must be a positive integer and defaults to 1, and if start < end the order of values is reversed, very rarely used - when needing to perform conditional removal of JSON keys or XML nodes. # behind the scenes, it could be creating (or over-writing) a bunch of variables ! How to run a specific feature file in karate? In some rare cases, for e.g. Assuming the above code is in a file called my-headers.js, the next section on calling other feature files shows how it looks like in action at the beginning of a test script. Setting values on JSON documents is simple using the set keyword. 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. some.feature:42 so it will invoke only the Scenario or outline Example on line 42 - this is designed only for IDE-s and developer mode, use a tag for maintainability. 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. When you have a large and complex project, you will end up with a few data files (e.g. A Gherkin file is saved with the ".feature" extension. So it is recommended that you directly use a Java Function when possible instead of using the karate.toJava() wrapper as shown above. But if you really need to use the HTTP response code in an expression or save it for later, you can get it as an integer: Note that match can give you some extra readable options: The response time (in milliseconds) for the current response would be available in a variable called responseTime. for (var n in nums) { The feature is invoked for each item in the array. Here are some examples: Now that we have seen how JSON is a native data type that Karate understands, there is a very nice way to create JSON using Cucumbers support for expressing data-tables. 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']. [{ If you are familiar with Cucumber (JVM), you may be wondering if you need to write step-definitions. Here is an . You can always use a JavaScript switch case within an eval or function block. In the feature below, the * print 'in setup' step will run only once. You can replace the values of com.mycompany and myproject as per your needs. Ex- headers. From a file in the same package. Note that this example only does a string equals check on parts of the JSON, but with Karate you are always encouraged to match the entire payload in one step. Dont forget that Karates data-driven testing capabilities can loop over arrays of JSON objects automatically. This is so that you can mix expressions into text replacements as shown below. The not equals operator != works as you would expect: You typically will never need to use the != (not-equals) operator ! It is sometimes useful to be able to check if a key-value-pair does not exist. object.name. You can optionally pass in variable values or over-ride config via a HashMap or leave the second-last argument as null. Try this especially if you dont have much experience with programming or test-automation. All JS native array operations can be used, such as someName.reverse(). Step 1 - Create a Gradle project. Do note that if you choose the Java API, you will naturally lose some of the test-automation framework benefits such as HTML reports, parallel execution and JavaScript / configuration. String interpolation will support variables in scope and / or the Examples (including functions defined globally, but not functions defined in the background). Note that Karate works fine on OpenJDK. Although it is just a few lines of code, take time to study the above example carefully. path to file containing the trust chain for your server certificate. feature file from your Java IDE, you just need the following empty test-class in the same package. 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. Karate will traverse sub-directories and look for *.feature files. The name of the class doesn't matter, and it will automatically run any *.feature file in the same package. 1. If you use the above config, logs will be captured in target/karate.log. { {}, """ Note that the set (multiple) keyword can build complex, nested JSON (or XML) from scratch in a data-driven manner, and you may not even need to read from files for many situations. Requirement: Open a feature file in VSCode Editor and ensure a line associated with a test has cursor focus. Until now, I have shown you run your test cases directly on feature files. And with Karate expressions, you can dive into JavaScript without needing to define a function - and conditional logic is a good example. Karates native support for JSON means that you can assign parts of a JSON instance into another variable, which is useful when dealing with complex response payloads. For JSON, you can also use the JS delete operator via eval, useful when the path you are trying to mutate is dynamic. In fact, this is the mechanism used when karate-config.js is processed on start-up. } Multi-values are supported the way you would expect (e.g. Linux: Ctrl+Shift+R+1. 2 name: 'Billie', But there are cases where you need to take custom actions like saving a response to a file, file reading or writing, etc. """, # * match cat == { name: '#ignore', type: '#regex . Karate supports the following functional-style operations via the JS API - karate.map(), karate.filter() and karate.forEach(). It short-cuts to the pre-defined variable responseHeaders and reduces some complexity - because strictly, HTTP headers are a multi-valued map or a map of lists - the Java-speak equivalent being Map>. The placeholder format defaults to angle-brackets, for example: . And since header names are case-insensitive - it ignores the case when finding the header to match. This is technically not in the key-value form: multipart field name = 'foo', but logically belongs here in the documentation. For details of scope and visibility of variables, see Script Structure. Karate can read *.csv files and will auto-convert them to JSON. The key should not be within quotes. Run Test Cases In Parallel & Generate Reports Using Karate Tool "c": 3 To check whether particular field in response is present and not null using match !null To assert response by ignoring value of particular field So, first lets understand what is response in Karate. Note that this is not supported for arrays like above, and you can have only one value column. count: '#number', we need to have our first feature file which will be called from the second feature file.Here I'm trying to explain using the Git Repo APIs. It can also be executed by using @GetValue Tag in an external feature. status: '#number? You get to choose how to manage your environment-specific configuration values such as user-names and passwords. And if you have a Scenario Outline, this happens for every row in the Examples. all the key-value pairs are added to the HTTP headers. This is a problem especially for expensive, time-consuming HTTP calls, and this has been an open issue for a long time. Heres a reminder that running any single JUnit test via Maven can be done by: Where CatsRunner is the JUnit class name (in any package) you wish to run. Do look at the documentation and example for configure headers also as it goes hand-in-hand with call. Karate provides an elegant native-like experience for placeholder substitution within strings or text content. Like above, but force the SSL algorithm to one of, Whether the HTTP client automatically follows redirects - (default, Set the connect timeout (milliseconds). Provides supports for the Data Driver Testing that is built in-house, hence no need to depend on external frameworks. Normally an undefined variable results in nasty JavaScript errors. And yes, functions can take arguments. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. A common requirement is to build an array with n elements or do something n times where n is an integer (that could even be a variable reference). in just one extra line you can save the value of karate.prevRequest and pass it around. Ideally you should return only pure JSON data (or a primitive string, number etc.). #(lang)#(user), """ Here is an example of performing a configure driver step in JavaScript: By default, Karate will add logs to the report output so that HTTP requests and responses appear in-line in the HTML reports. In fact it may be a good idea to slip doubles instead of integers into some of your tests ! The csv and yaml types can be initialized in-line using the triple quote or docstring multi-line approach as shown here. Native data types mean that you can insert them into a script without having to worry about enclosing them in strings and then having to escape double-quotes all over the place. but if you want to run only a specific feature file from a JUnit test even if there are multiple *.feature files in the same folder . If you face issues such as class not found, just pull in the karate-core dependency, and use the all classifier in your pom.xml (or build.gradle). karate | Multiple Scenarios in a single feature - YouTube A URL remains constant until you use the url keyword again, so this is a good place to set-up the non-changing parts of your REST URL-s. A URL can take expressions, so the approach below is legal. if the name is "first": And if you use IntelliJ - you can right click and do the above. While converting a number to a string is easy (just concatenate an empty string e.g. Karate makes re-use of payload data, utility-functions and even other test-scripts as easy as possible. This is a good time to deep-dive into JsonPath, which is perfect for slicing and dicing JSON into manageable chunks. You can read more about the Given-When-Then convention at the Cucumber reference documentation. id: '#regex[0-9]+', Empty cells or expressions that evaluate to null will result in the key being omitted from the JSON. Making statements based on opinion; back them up with references or personal experience. In this file, we will write out the test scenarios that need to be executed for performing the API Testing. Paste the raw json in it and Save it. Valid options are, Function to be called when displaying image comparison rebase in Karate HTML reports (e.g. By now, it should be clear that JsonPath can be very useful for extracting JSON trees out of a given object. The argument can be provided after the function name, without parentheses, which makes things slightly more readable (and less cluttered) especially when the solitary argument is JSON. It is actually a transpose of the table approach, and can be very convenient when there are a large number of keys per row or if the nesting is complex. Match failure messages are much more descriptive and useful, and you get the power of embedded expressions and fuzzy matching. Does ZnSO4 + H2 at high pressure reverses to Zn + H2SO4? Karate has built-in support for re-trying an HTTP request until a certain condition has been met. You can easily assign the whole response (or just parts of it using Json-Path or XPath) to a variable, and use it in later steps. 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. Karate Runner - Visual Studio Marketplace Give a name to the feature file. This means that all your. Although rarely needed, variable references or expressions are also supported: This is a shortcut to assert the HTTP response code. Allowed keystore types are as described in the, if all server certificates should be considered trusted. Load testing. _ >= 0', 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.
