It validates the entire payload in one step and checks if the kittens array contains all the expected items but in any order. { For those who may prefer YAML as a simpler way to represent data, Karate allows you to read YAML content from a file - and it will be auto-converted into JSON. But you can prefix the name with classpath: in which case the root folder would be src/test/java (assuming you are using the recommended folder structure). Calling any Java code is that easy. Karate API Testing Tool Cheat Sheet - DevQA.io karate-chrome. Set the read timeout (milliseconds). 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). REST API Testing with Karate | Baeldung Another example is dogs.feature - which actually makes JDBC (database) calls, and since the data returned from the Java code is JSON, the last section of the test is able to use match very effectively for data assertions. Type the following commands: mvn spring-boot:run & mvn test -Dtest=KarateTests. { id: { domain: "DOM", type: "entityId", value: "#ignore" }, feature file from your Java IDE, you just need the following empty test-class in the same package. You may have to rely on unit-testing frameworks or integrate additional dependencies. For Gradle, you simply specify the test which is to be include-d: The big drawback of the approach above is that you cannot run tests in parallel. It is like defining variables in any programming language. How to configure karate to stop execution when any scenario fails? 'test1.feature', * def result = responseStatus == 404 ? // trigger download of latest image with custom file name A great example of how you can extend Karate, even bypass the HTTP client but still use Karates test-automation effectively, is this gRPC example by @thinkerou: karate-grpc. Karates approach frees you from Maven, is far more expressive, allows you to eyeball all environments in one place, and is still a plain-text file. }, So you get the best of both worlds: the elegance of JSON to express complex nested data - while at the same time being able to dynamically plug values (that could even be other JSON or XML trees) into a template. EDIT: Karate now supports being able to use a line-number, for e.g. _ == _$.roomInformation[0].roomPrice' }, """ This is useful in any situation where you need to concatenate dynamic string fragments to form content such as GraphQL or SQL. """, # note the 'text' keyword instead of 'def', """ jbang is a great way for you to install and execute scripts that use Karates Java API on any machine with minimal setup. Making statements based on opinion; back them up with references or personal experience. 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. You can set this up for all subsequent requests or dynamically generate headers for each HTTP request if you configure headers. id: 1, 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. Create Karate API Test Script( Feature File ) - TestingDocs.com name: John But the when using Run option on an individual scenario, i get the following error Multi-value headers (though rarely used in the wild) are also supported: Also look at the headers keyword which uses JSON and makes some kinds of dynamic data-driven testing easier. 82 lines (69 sloc) 3.06 KB. Note that jbang itself is super-easy to install and there is even a Zero Install option. A Java API also exists for those who prefer to programmatically integrate Karates rich automation and data-assertion capabilities. ##(subSchema) As a short-cut, when running JsonPath expressions - $ represents the response. And JSON arrays would become Java List-s. 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. There are examples of calling JVM classes in the section on Java Interop and in the file-upload demo. 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. 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. * url myUrl. The configure key here is report and it takes a JSON value. Karate Tests you can immediately run, with validation, inline payload examples and . If you want to use JUnit 4, use the karate-junit4 Maven dependency instead of karate-junit5 . For JSON, you can also use the JS delete operator via eval, useful when the path you are trying to mutate is dynamic. Heres how it works: Here is a contrived example that uses match each, contains and the #? After one year KarateIDE have reached Version 1.0.0.The best user experience for KarateDSL, by far!! In fact, this is the mechanism used when karate-config.js is processed on start-up. Does ZnSO4 + H2 at high pressure reverses to Zn + H2SO4? """, # use dynamic path expressions to mutate json, * def filename = zone == 'zone1' ? }] } Notice that in the above example, string values within the table need to be enclosed in quotes. for (var n in nums) { The match syntax involves a double-equals sign == to represent a comparison (and not an assignment =). This is rarely used, unless you are expecting binary content returned by the server. For JUnit 5 you can omit the public modifier for the class and method, and there are some changes to import package names. For convenience, non-existent keys (or array elements) will be created automatically. id: '#regex[0-9]+', To run the application in multiple environments choose one of the environment-specific commands from the following: 1] npm run start:development 2] npm run build:staging 3] npm run build:qa 4] npm run build:production Access the variables in-app For accessing the variables in the .env file you should use the process. You can even mix domain and conditional validations and perform all assertions in a single step. Since this is a frequently asked question, the different ways of being able to re-use code (or data) are summarized below. Other errors could be a java.net.URISyntaxException and match not working as expected because of special or foreign characters, e.g. Karate is even able to ignore fields you choose - which is very useful when you want to handle server-side dynamically generated fields such as UUID-s, time-stamps, security-tokens and the like. if the name is "first": And if you use IntelliJ - you can right click and do the above. Also note that match contains any is possible for JSON objects as well as JSON arrays. The special predicate marker #? Note that Karate works fine on OpenJDK. JavaScript Functions are also native. Windows: Ctrl+R+A. This can be convenient if a particular call results in a huge response payload. 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, """ The name of the class doesn't matter, and it will automatically run any *. function() { The answer is no. You can replace the values of com.mycompany and myproject as per your needs. mvn clean test-compile gatling:test -Dgatling.simulationClass=Performance.GatlingTest Gatling script with Karate feature file. 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. This is super-useful for re-use and data-driven tests. So you can do things like this: * def name = name + __loop - or you can use the loop index value for looking up other values that may be in scope - in a data-driven style. The primary classes are described below. an initial 'sign-in' that retrieves some secure tokens, every subsequent. { id: 42, name: 'Wild' } 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. Some users need callable features that are re-usable even when variables have not been defined by the calling feature. This is a sample Spring Boot web-application that exposes some functionality as web-service end-points. Create a Test Runner class. The JS API has a karate.signal(result) method that is useful for involving asynchronous flows into a test. """, """ For example: While the tag does not need to be in the @key=value form, it is recommended for readability when you start getting into the business of giving meaningful names to your Scenario-s. For example if you have the JUnit class in the com.mycompany package, *.feature files in com.mycompany.foo and com.mycompany.bar will also be run. Karate is an open-source API test automation tool. Use this for building multipart named (form) field requests. time: '#? Also refer to the wiki for using Karate with Gradle. myInt + ''), in some rare cases, you may need to convert a string to a number. Note that the special, built-in tag @ignore will always be skipped by default, and you dont need to specify ~@ignore anywhere. You also have the option of setting multiple cookies in one-step using the cookies keyword. You can if you want to, but since only JsonPath (on variables) is allowed here, Karate ignores the $ and looks only at the variable name. You can easily get the value of the current environment or profile, and then set up global variables using some simple JavaScript. This demonstrates a Java Maven + JUnit 5 project set up to test a Spring Boot app. Raw Blame. Keywords such as set and remove allow you to to tweak payload-data to fit the scenario under test. will get encoded into %3F. A common requirement is to pass dynamic parameter values via the command line, and you can use the karate.properties['some.name'] syntax for getting a system property passed via JVM options in the form -Dsome.name=foo. Karate is the only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. This is so that you can mix expressions into text replacements as shown below. And each element of the returned array will be the envelope of variables that resulted from each iteration where the *.feature got invoked. Refer to the section on JsonPath short-cuts for a deeper understanding of named JsonPath expressions in Karate. Match failure messages are much more descriptive and useful, and you get the power of embedded expressions and fuzzy matching. In rare cases you may want to suppress the default of Scenario-s executing in parallel and the special tag @parallel=false can be used. Run All Karate Tests. In case you were wondering, variables (and even expressions) are supported on the right-hand-side. Karate has enhanced the Cucumber Scenario Outline as follows: These are best explained with examples. Keep in mind that these are tests (not production code) and this config is going to be maintained more by the dev or QE team instead of the ops or operations team. Run Cucumber Test from Maven Command Line - QA Automation Expert """, # in this case the solitary 'call' argument is of type string. And there is another example in the karate-demos: schema.feature where you can compare Karates approach with an actual JSON-schema example. The above example does not use shared scope, which means that the variables in the calling (parent) feature are not shared by the called my-signin.feature. path to file containing the trust chain for your server certificate. Keep in mind that the start-up configuration routine could have already initialized some variables before the script even started. How to run feature files in parallel-using Karate test automation rev2023.3.3.43278. For suppressing sensitive information such as secrets and passwords from the log and reports, see Log Masking and Report Verbosity. The .graphql and .gql extensions are also recognized (for GraphQL) but are handled the same way as .txt and treated as a string. "b": 2, } Use a variable in the called feature instead, for e.g. For JSON and XML files, Karate will evaluate any embedded expressions on load. You can run tests with this directly, but teams can choose the JUnit variant (shown below) that pulls in JUnit 5 and slightly improves the in-IDE experience. Also note how you can wrap the LHS of the match in parentheses in the rare cases where the parser expects JsonPath by default. Here are some examples: Refer to this file for a comprehensive set of XML examples: xml.feature. ZenWave Karate IDE - Visual Studio Marketplace The tests eecutes fine if i use maven command or run from runner file( .java). predicate marker to validate that the value of totalPrice is always equal to the roomPrice of the first item in the roomInformation array. How to call a feature file from another feature file in karate How to call custom Java code in karate API tests? Note that more builder methods are available from the Runner.Builder class such as reportDir() etc. Feature: We use it to identify the feature file and give it a small title or a one line definition. For example - if a response data element or downloaded file is YAML and you need to use the data in subsequent steps. The documentation on how to run tests via the command line has an example of how to use tags to decide which tests to not run (or ignore). # but karate allows you to traverse xml like json !! all the key-value pairs are added to the HTTP headers. You dont have to compile code. When eyeballing a test-script, think of the * as a bullet-point. For another example, see: examples.feature. Note that the Content-Type header will be automatically set to: application/x-www-form-urlencoded. Something worth mentioning here is that you would hardly need to use assert in your test scripts. Billie,LOL Karate has a very useful payload templating approach. 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. 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. You should take a minute to compare this with the exact same example implemented in REST-assured and TestNG. countryName: '#string', #string This example also shows how you can use a custom placeholder format instead of the default: Refer to this file for a detailed example: replace.feature. You use the listen keyword (with a timeout) to wait until that event occurs. Some characters such as the hyphen - are not permitted in lenient JSON keys (because they are interpreted by the JS engine as a minus sign). When using call (or callonce), only one argument is allowed. """, # * match cat == { name: '#ignore', type: '#regex . Normally an undefined variable results in nasty JavaScript errors. } After every HTTP call this variable is set with the response body, and is available until the next HTTP request over-writes it. 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. 'name is Bob and age is 5', # the single cell can be any valid karate expression, * def generator = function(i){ if (i == 20) return null; return { name, Keywords that set multiple key-value pairs in one step, Managing Headers, SSL, Timeouts and HTTP Proxy, Matching Sub-Sets of JSON Keys and Arrays, mix Karate into Java projects or legacy UI-automation suites, Karate entered the ThoughtWorks Tech Radar, 7 New Features in Karate Test Automation Version 1.0, nested chunks of JSON that name-space your config variables, alternate way of calling JavaScript functions, exact same example implemented in REST-assured and TestNG, do not use this unless you know what you are doing, see above, Comparison engine(s) to use. 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. Now it should be clear how Karate makes it easy to express JSON or XML. JSON can be combined with the ability to call other *.feature files to achieve dynamic data-driven testing in Karate. Conditionally making a test fail is easy with karate.fail(). You can even create (or modify existing) JSON arrays by using multiple columns. Multiple feature files (or paths) can be specified, de-limited by the space character. 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. You can use callonce instead of call within the Background in case you have multiple Scenario sections or Examples. right: 1496 For example: Note that it has to be a pure JavaScript expression - which means that match syntax such as contains will not work. And you dont need to create additional Java classes for any of the payloads that you need to work with. { Also refer to this demo example for a working example of multipart file uploads: upload.feature. Before we get to the HTTP keywords, it is worth doing a recap of the various shapes that the right-hand-side of an assignment statement can take: They are url, path, request, method and status. You can choose between the string-placeholder style or directly refer to the variable foo (or even the whole row JSON as __row) in JSON-friendly expressions. 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. Add the plugin to the / section of your pom.xml if not already present: If you want to use JUnit 4, use the karate-junit4 Maven dependency instead of karate-junit5. left: 1085, !contains deep is not yet supported, please contribute code if you can. """, Then match each json.hotels contains { totalPrice, #? 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. to customize configuration output), Array of rectangles that should be ignored during image comparison, Resemble ignore preset. 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. You can even remove JSON array elements by index. There is no need to escape characters like you would have had to in Java or other programming languages. This is actually the intent most of the time and is convenient. Karate can run tests in parallel, and dramatically cut down execution time. A Gherkin file is saved with the ".feature" extension. VNC server exposed on port 5900 so that you can watch the browser in real-time. How to save karate.prevrequest between feature files? foo: 'hello', a JSON array). Since these are tests and not production Java code, you dont need to be bound by the com.mycompany.foo.bar convention and the un-necessary explosion of sub-folders that ensues. Important: do not use the @RunWith(Karate.class) annotation. The problem is, I want to use other config values as shown here but when I run the test, it fails to access config.ApiKey correctly. What this means is that you are free to use whatever makes sense for you. Also make sure that you complete the set up of things like url, param, header, configure etc. Refer to the cats-java.feature demo for an example. Another good thing that Karate inherits is the nice IDE support for Cucumber that IntelliJ and Eclipse have. This is a normal JUnit 4 test class ! To make dynamic data-driven testing easier, the following keywords also exist: params, headers, cookies and form fields. 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. 8 How to test the Karate API cheat sheet? _ > 0'. Note that if you need to do a lot of case-insensitive string checks, karate.lowerCase() is what you are looking for. When you use Karate, all your data assertions can be done in pure JSON and without needing a thick forest of companion Java objects. Refer to this case study for how dramatic the reduction of lines of code can be. data: { All arrays no matter the depth will be checked in this way. It gets the value of any Java system-property by name. Link to my code repo on Git hubhttps://github.com/KalimohTraining/KarateTrainingLink to Karate Project on GitHub:https://github.com/intuit/karateDescription . Open a feature file after you have installed the plug-in. If a file does not end in .json, .xml, .yaml, .js, .csv or .txt, it is treated as a stream - which is typically what you would need for multipart file uploads. for advanced users - scripts can introspect the tags that apply to the current scope, refer to this example: for even more advanced users - Karate natively supports tags in a, when you want to get the absolute OS path to the argument which could even have a prefix such as, converts a JSON string or map-like object into a Java object, given the Java class name as the second argument, refer to this, converts a JSON array (of objects) or a list-like object into a CSV string, writing this to a file is your responsibility or you could use, rarely used, when you need to pass a JS function to custom Java code, typically for, for advanced conditional logic when object types are dynamic and not known in advance, see, returns only the values of a map-like object (or itself if a list-like object), will wait until the URL is ready to accept HTTP connections, will wait until the host:port is ready to accept socket connections, the current iteration index (starts from 0) if being called in a loop, will be, Java knowledge is not required and even non-programmers can write tests, Scripts are plain-text, require no compilation step or IDE, and teams can collaborate using Git / standard SCM, Based on the popular Cucumber / Gherkin standard - with, Eliminate the need for Java Beans or helper code to represent payloads and HTTP end-points, and, Ideal for testing the highly dynamic responses from, Tests are super-readable - as scenario data can be expressed in-line, in human-friendly, Express expected results as readable, well-formed JSON or XML, and, Embedded JavaScript engine that allows you to build a library of, Re-use of payload-data and user-defined functions across tests is, Standard Java / Maven project structure, and, Reports include HTTP request and response, Easily invoke JDK classes, Java libraries, or re-use custom Java code if needed, for. Refer to the section on XPath Functions for examples of advanced XPath usage. { Here is an example of an implementation. Other options are the quickstart or the standalone executable. 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 this example may make it clear why using Karate itself to drive even your UI-tests may be a good idea. When JavaScript executes in Karate, the built-in karate object provides some commonly used utility functions. This is best explained via, returns the size of the map-like or list-like object. In This video explained how to call one feature file from another feature file by using the call and read functions. You need to use karate.toJava() to wrap JS functions passed to custom Java code. for simulating check-boxes and multi-selects): You can also dynamically set multiple fields in one step using the form fields keyword. One workaround is to temporarily disable or rename your Maven settings.xml file, and try again. This can be achieved using karate.callSingle(). Mac: Cmd+V. This can be a lot simpler than embedded expressions in many cases, and JavaScript programmers will feel right at home. Note that this mode can be also triggered via the command-line by adding -D or --dryrun to the karate.options. Heres a reminder that the #notpresent marker can be mixed into an equality match (==) to assert that some keys exist and at the same time ensure that some keys do not exist: The ! Here below are a few more common examples: The first three are good enough for random string generation for most situations. Let's have a look over the a very simple and plane gatling script which uses Karate .
