karate run specific feature file

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. Refer to the section on JsonPath short-cuts for a deeper understanding of named JsonPath expressions in Karate. They are param, header, cookie, form field and multipart field. { Here I have defined a variable expectedOutput with def keyword. The Hello World is a great example of REST-ful use of the url when the test focuses on a single REST resource. } So an additional rule in the above flow of rules (before the first step) is as follows: Karate scripts are technically in Gherkin format - but all you need to grok as someone who needs to test web-services are the three sections: Feature, Background and Scenario. Since XML is represented internally as a JSON-like or map-like object, if you perform string concatenation when printing, you will not see XML - which can be confusing at first. # using a static method - observe how java interop is truly seamless ! Make sure you configure your source code management system (e.g. If needed, this can be changed by using configure - any time during a test, or set globally via karate-config.js. 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. Karate with Gatling - Knoldus Blogs karate. Mac: Cmd+R+1. And you can mix API and UI test-automation within the same test script. Karate tool provides you with the step definitions. They seamlessly fit in-line within your test script. 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 ! deleted: false 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. That said, if you want to stick to JavaScript, but find yourself accumulating a lot of helper functions that you need to use in multiple feature files, the following pattern is recommended. function(s) { For some more examples check test-outline-name-js.feature. """, Then match each response contains deep { a, # should be an array of strings with size 2, # each array element should have a 'length' property with value 3, # should be an array of strings each of length 3, """ The JavaScript interpreter will try to convert types across Java and JavaScript as smartly as possible. Each item within responseCookies is itself a map-like object. Karate DSL : Getting started - Knoldus Blogs For more complex functions you are better off using the multi-line doc-string approach. Note that this is not supported for arrays like above, and you can have only one value column. Custom header manipulation for every HTTP request is something that Karate makes very easy and pluggable. "a": 1, 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 ! You simply roll your own. You cant do things such as * url 'http://foo.bar' and expect the URL to be set in the called feature. And here is how cat-create.feature could look like: If you replace the table with perhaps a JavaScript function call that gets some JSON data from some data-source, you can imagine how you could go about dynamic data-driven testing. Note how even calls to Java code can be made if needed. karate-chrome. All the fuzzy matching markers will work in XML as well. for (var n in nums) { // trigger download of latest image with custom file name The first four below are best explained in this example file: type-conv.feature. And yes, functions can take arguments. input: In some rare cases, for e.g. Definition. Assuming you use JUnit, there are some good reasons for the recommended (best practice) naming convention and choice of file-placement shown above: For details on what actually goes into a script or *.feature file, refer to the syntax guide. odd: '#(oddSchema)', bar: 'world' Also look at the section on commonly needed utilities for more ideas. In This video explained how to call one feature file from another feature file by using the call and read functions. You can even mix domain and conditional validations and perform all assertions in a single step. Wood shutters will run you $200 to $350 per . See the section on reading files - and also this example dynamic-csv.feature, which shows off the convenience of dynamic Scenario Outline-s. # and even ignore fields at the same time ! And you can even handle asynchronous flows such as listening to message-queues. Variables set using def in the Background will be re-set before every Scenario. 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. to save space and speed up report loading), * configure imageComparison = { hideUiOnSuccess, # ignore areas of an image (e.g. The approach in this section is more suited for troubleshooting in dev-mode, using your IDE. Give a name to the feature file. This is a very powerful way to generate test-data without having to load a large number of data rows into memory. Karate-config.js, Is it possible to run java method after every karate scenario? '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. 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. #24: You can execute the scenario defined in @GetValue alone in the current file (=get.feature),. When you use Karate, all your data assertions can be done in pure JSON and without needing a thick forest of companion Java objects. The function argument is the row-index, so you can easily determine when to stop the generation of data. function() { Then use the header keyword to do a custom over-ride if needed. Note that the special, built-in tag @ignore will always be skipped by default, and you dont need to specify ~@ignore anywhere. 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. The name of the class doesn't matter, and it will automatically run any *.feature file in the same package. 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. 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. You can define the variables with the def keyword in the feature file directly. These are built-in variables, there are only a few and all of them give you access to the HTTP response. Something worth mentioning here is that you would hardly need to use assert in your test scripts. But since some-reusable.feature is above AnimalsTest.java in the folder hierarchy, it will not be picked-up. Add an automation story in BDD syntax. By default, the value of karate.env when you access it within karate-config.js - would be null. english Here is how to replace one placeholder at a time: Karate makes it really easy to substitute multiple placeholders in a single, readable step as follows: Note how strings have to be enclosed in quotes. The JS API has a karate.signal(result) method that is useful for involving asynchronous flows into a test. Here is a good example in the demos: dynamic-params.feature, The single JSON argument needs to be in the form { field1: { read: 'file1.ext' }, field2: { read: 'file2.ext' } } where each nested JSON is in the form expected by multipart file. { How to declare variable in karate? - Technical-QA.com You can find more examples here: xml.feature. Also refer to the wiki for using Karate with Gradle. The listenResult magic variable will hold the value passed to the call to karate.signal(). This mechanism works by calling configure cookies behind the scenes and if you need to stop auto-adding cookies for future requests, just do this: Also refer to the built-in variable responseCookies for how you can access and perform assertions on cookie data values. 5678 feature file from your Java IDE, you just need the following empty test-class in the same package. 12341234 # behind the scenes, it could be creating (or over-writing) a bunch of variables ! You could use it for hard-coded absolute paths in dev mode, but is obviously not recommended for CI test-suites. Multiple feature files (or paths) can be specified, de-limited by the space character. You can change the com.intuit.karate logger level to INFO to reduce the amount of logging. The default is 30000 (30 seconds). JavaScript Functions are also native. If you are looking for a way to do something only once per Feature, take a look at callonce. please replace RELEASE with the exact version of Karate you intend to use if applicable. 'put', # if you have dynamic keys you can do this, # enable ssl (and no certificate is required), # enable ssl and force the algorithm to TLSv1.2, # time-out if the response is not received within 10 seconds (after the connection is established), # set the uri of the http proxy server to use, https://user:password@zalenium.net/wd/hub, # if this was in karate-config.js, it would apply "globally", # enable X509 certificate authentication with PKCS12 file 'certstore.pfx' and password 'certpassword', # trust all server certificates, in the feature file, // trust all server certificates, global configuration in 'karate-config.js', # add new keys. Important: do not use the @RunWith(Karate.class) annotation. But use wisely, because called scripts will now over-write variables that may have been already defined. """, """ You can also find a nice visual comparison and explanation here. 82 lines (69 sloc) 3.06 KB. Asking for help, clarification, or responding to other answers. And you dont need to create additional Java classes for any of the payloads that you need to work with. 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. height For a call (or callonce) - payload / data structures (JSON, XML, Map-like or List-like) variables are passed by reference which means that steps within the called feature can update or mutate them, for e.g. Singapore, city-state located at the southern tip of the Malay Peninsula, about 85 miles (137 kilometres) north of the Equator. To create a feature file, right click on the Project explorer, choose New >> File. Note that because the <execution> phase is defined for test, just running mvn clean test will work. And as a testing framework, Karate discourages tests that give different results on every run. Here below is an example that also demonstrates using the multipart/related content-type. Karate has a very useful payload templating approach. Karate is an open-source general-purpose test-automation framework that can script calls to HTTP end-points and assert that the JSON or XML responses are as expected. German or ISO-8859-15. match each can be combined with contains deep so that for each JSON object a deep contains match is performed within nested lists or objects. 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. Things are designed so that you can plug-in what you need, without needing to compile Java code. They should be at the end of the karate.options. The not equals operator != works as you would expect: You typically will never need to use the != (not-equals) operator ! function(arg) { The special tag @report=false can be used, and it can even be used only for a single Scenario: In cases where you want to mask values which are sensitive from a security point of view from the output files, logs and HTML reports, you can implement the HttpLogModifier and tell Karate to use it via the configure keyword. * url myUrl. You may face issues if you attempt to mix in JS functions or Java code. var date = new java.util.Date(); Valid options are, Resemble option to ignore a specific color, Resemble option to override preset tolerances for color and brightness, SSIM grayscale algorithm. Because Karate strips trailing slashes if part of a path parameter, if you want to append a forward-slash to the end of the URL in the final HTTP request - make sure that the last path is a single /. The @setup tag is built-in for this purpose and any Scenario tagged with this will behave like @ignore. 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. The last row in the table is a little different from the rest, and this short-cut form is the recommended way to validate the length of a JSON array. As a convenience, you can call a tag directly, which is a short-cut to call another Scenario within the same feature file. 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. For e.g. It is sometimes useful to be able to check if a key-value-pair does not exist. } And any variables which are alive in the context can be used in this expression. The feature file is an entry point, to write the cucumber tests and used as a live document at the time of testing. Refer to this case study for how dramatic the reduction of lines of code can be. To do that, add the following: And then the above command in Gradle would look like: The recommended way to define and run test-suites and reporting in Karate is to use the parallel runner, described in the next section. For example - if a response data element or downloaded file is YAML and you need to use the data in subsequent steps. This will create a folder called myproject (or whatever you set the name to). You could even have all the steps start with When and Karate wont care. That said, if you really need to implement conditional checks, this can be one pattern: And this is another, using karate.call(). Instead of using call (or callonce) you are always free to call JavaScript functions normally and then you can use more than one argument. { For convenience, non-existent keys (or array elements) will be created automatically. Conditional logic is not recommended especially within test scripts because tests should be deterministic. Calling the feature file from another feature file using karate Heres thearticle. Note that embedded expressions will be evaluated even when you read() from a JSON or XML file. If you want to use JUnit 4, use karate-junit4 instead of karate-junit5. If a handler function (returning a boolean) is provided - it will be used to complete the listen wait if true is returned. 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. ] Here are some examples: Refer to this file for a comprehensive set of XML examples: xml.feature. You can even retrieve operating-system environment variables via Java interop as follows: var systemPath = java.lang.System.getenv('PATH'); This decision to use JavaScript for config is influenced by years of experience with the set-up of complicated test-suites and fighting with Maven profiles, Maven resource-filtering and the XML-soup that somehow gets summoned by the Maven AntRun plugin. [{ You should see the Karate: Run | Karate: Debug code lense on top of the feature and every scenario. } Karate report & karate log to have scenario name with test data. More examples of Java interop and how to invoke custom code can be found in the section on Calling Java. Here is a recap of symbols that can be used in JSON embedded expressions: There is a shortcut for match each explained in the next section that can be quite useful, especially for in-line schema-like validations. You can always use a JavaScript function or call Java for more complex logic. You can optionally pass in variable values or over-ride config via a HashMap or leave the second-last argument as null. Then we can run the mem_report helper function to check the used/available GPU statistics. # but karate allows you to traverse xml like json !! In situations where you start an (embedded) application server as part of the test set-up phase, a typical challenge is that the HTTP port may be determined at run-time. Although it is just a few lines of code, take time to study the above example carefully. 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). In this file, we will write out the test scenarios that need to be executed for performing the API Testing. . Run the tests from Command Line. Note that the parser is lenient so that you dont have to enclose all keys in double-quotes. When re-running tests in development mode and when your test suite depends on say an Authorization header set by karate.callSingle(), you can cache the results locally to a file, which is very convenient when your auth token is valid for a period of a few minutes - which typically is the case. You can actually refer to any JsonPath on the document via $ and perform cross-field or conditional validations ! id: 1, 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. For example, if you have a runner under . cheney brothers price list Transforming homes for over 40 years with custom blinds, shades, shutters and drapery. Karate is built on top of Cucumber, another BDD testing framework, and shares some of the same concepts. For manipulating or updating JSON (or XML) using path expressions, refer to the set keyword. See this for an example. For example: For Gradle, you must extend the test task to allow the karate.options to be passed to the runtime (otherwise they get consumed by Gradle itself). So how can you get this value injected into the Karate configuration ? And since header names are case-insensitive - it ignores the case when finding the header to match. """, # very useful for validating a response against a schema "super-set", * match karate.filterKeys(response, 'b', 'c') == { c, * match karate.filterKeys(response, ['a', 'b']) == { a, # generate a range of numbers as a json array, """ But normally a match statement is preferred unless you want a really descriptive error message. This is especially useful when capturing screenshots during tests and comparing against baseline images that are known to be correct. Difficulties with estimation of epsilon-delta limit proof. Note that it is a map of lists so you will need to do things like this: And just as in the responseCookies example above, you can use match to run complex validations on the responseHeaders. ##(subSchema) } OR: To run every feature that has either of the @F1 and @F2 tags (runs both) {@F1,@F2}, Combining OR and AND: To run feature that has either of @F1,@F2,@F3 tags but not @F4 tag. The syntax is similar to def but instead of a named variable, you update configuration. sorts the list using the provided custom function called for each item in the list (and the optional second argument is the item index) e.g. Refer to karate.tags and karate.tagValues. hero(name: "") { It can also be argued that the # symbol is easy to spot when eyeballing your test scripts - which makes things more readable and clear. There may be cases where you want to suppress this to make the reports lighter and easier to read. All JS native array operations can be used, such as someName.reverse(). Karate provides a far more simpler and more powerful way than JSON-schema to validate the structure of a given payload. A stand-alone example can be found here: examples/image-comparison along with a video explanation. But you can easily achieve any complex logic by using the JS API. Until now, I have shown you run your test cases directly on feature files. If you really need to re-use a Java function, see Java Function References. This is possible by prefixing contains with a ! The $varName form is used on the right-hand-side of Karate expressions and is slightly different from pure JsonPath expressions which always begin with $. This is technically not in the key-value form: multipart field name = 'foo', but logically belongs here in the documentation. Create a new job using the +Add new job link. JsonPath filter expressions are very useful for extracting elements that meet some filter criteria out of arrays. Finally, using karate.response.header(name) can be simpler to just get a header value string by name, and it will ignore-case for the name passed as the argument: You would normally only need to use the status keyword. As a convenience, cookies from the previous response are collected and passed as-is as part of the next HTTP request. The primary classes are described below. Requirement: Open a feature file in VSCode Editor and ensure editor has focus. A handler function is needed only if you have to ignore some incoming traffic and stop the wait when a certain payload arrives. For details of scope and visibility of variables, see Script Structure. You can also compare images using Karate path prefixes (e.g. For example: You can reset default settings by using the following short-cut: Since you can use configure any time within a test, you have control over which requests or steps you want to show / hide. Testing a Java Spring Boot REST API with Karate - Semaphore . The match syntax involves a double-equals sign == to represent a comparison (and not an assignment =). And if you need multiple functions, you can easily organize them into a single Java class with multiple static methods. Just write the url then base URL after that. Instead you would typically use the match keyword, that is designed for performing powerful assertions against JSON and XML response payloads. 10 How to call custom Java code in karate API tests? 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. But the when using Run option on an individual scenario, i get the following error Normally an undefined variable results in nasty JavaScript errors. Note that the ? What is the point of Thrower's Bandolier? 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. You should take a minute to compare this with the exact same example implemented in REST-assured and TestNG. Set the read timeout (milliseconds). Note that more builder methods are available from the Runner.Builder class such as reportDir() etc. Refer to the documentation on type-conversion to make sure you can unpack data returned from Karate correctly, especially when dealing with XML. Anyway, there are times when you may want to force integers (perhaps for cosmetic reasons) and you can easily do so using the double-tilde short-cut: ~~. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. The classpath is a Java concept and is where some configuration files such as the one for logging are expected to be by default. status: '#number? Here are the rules Karate uses on bootstrap (before every Scenario or Examples row in a Scenario Outline): Advanced users who build frameworks on top of Karate have the option to supply a karate-base.js file that Karate will look for on the classpath:. Karate API Testing Tool Cheat Sheet - DevQA.io So if you tried to re-use the same feature but with multiple arguments, things will not work as you expect. How to run a specific feature file in Karate? The key should not be within quotes. You can find more JSON examples here: js-arrays.feature. } The karate-demo has an example showing various ways to configure or set headers: headers.feature. Do note that if you prefer a pure Java API - Karate has that covered, and with far more capabilities. In such cases it might be desirable to have your tests using karate.logger.debug('your additional info') instead of the print keyword so you can keep logs in your pipeline in INFO.
