karate run specific feature file

The rest can also be used even in primitive data matches like so: If two cross-hatch # symbols are used as the prefix (for example: ##number), it means that the key is optional or that the value can be null. The Background is optional. This is a core feature and does not depend on JUnit, Maven or Gradle. It is a great example of how to effectively use the unique combination of Cucumber and JsonPath that Karate provides. 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. var nums = [0, 1, 2, 3, 4]; Raw Blame. You can even create (or modify existing) JSON arrays by using multiple columns. 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). Some users need callable features that are re-usable even when variables have not been defined by the calling feature. Only recommended for advanced users, but this guarantees a routine is run only once, even when running tests in parallel. Since match and set go well together, they are both introduced in the examples in the section below. The function is expected to return a JSON object and all keys and values in that JSON object will be made available as script variables. returns the last HTTP response as a JS object that enables advanced use-cases such as getting a header ignoring case: returns the last HTTP request as a JS object that enables advanced use-cases such as getting a header ignoring case: get metadata about the currently executing, sets the value of a variable (immediately), which may be needed in case any other routines (such as the, where the single argument is expected to be a, only needed when you need to conditionally build payload elements, especially XML. So if you really wanted to assert that the HTTP response body is well-formed JSON or XML you can do this: Very rarely used - but you can get the Java system-time (for the current response) at the point when the HTTP request was initiated (the value of System.currentTimeMillis()) which can be used for detailed logging or custom framework / stats calculations. Making statements based on opinion; back them up with references or personal experience. And a very common need would be to use a file as the request body: The rarely used file: prefix is also supported. You can find more JSON examples here: js-arrays.feature. They can be very useful in some situations. This section will be run before each script in the feature file. EDIT: Karate now supports being able to use a line-number, for e.g. Only one JSON argument is allowed, but this does not limit you in any way as you can use any complex JSON structure. Here is an example, where the same websocket connection is used to send as well as receive a message. } When JavaScript executes in Karate, the built-in karate object provides some commonly used utility functions. 2 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 . The configure key here is report and it takes a JSON value. 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. created: { on: "#ignore" }, This is especially useful when capturing screenshots during tests and comparing against baseline images that are known to be correct. _ == _$.roomInformation[0].roomPrice' }, """ } This is preferred because it takes care of situations such as if the value is undefined in JavaScript. If you don't want to run Gatling tests as part of the normal Maven test lifecycle, you can avoid the <executions> section as described previously.. Gradle . You can define the base URL in Karate with the keyword. You get to choose how to manage your environment-specific configuration values such as user-names and passwords. And if you need multiple functions, you can easily organize them into a single Java class with multiple static methods. Might be desirable instead of, useful to brute-force all keys and values in a JSON or XML payload to lower-case, useful in some cases, see, functional-style map operation useful to transform list-like objects (e.g. 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. Git) to ignore karate-config-*.js if needed. Imperialism is the state policy, practice, or advocacy of extending power and dominion, especially by direct territorial acquisition or by gaining political and economic control of other areas, often through employing hard power (economic and military power), but also soft power (cultural and diplomatic power).While related to the concepts of colonialism and empire, imperialism is a distinct . (with no space in between). """, * configure imageComparison = { onShowRebase, # custom JS function called in Karate HTML image comparison UI when the user clicks the `Show config` button, """ Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, Thanks @peter-thomas for the hints. """, * def timeLong = call dateStringToLong '2016-12-24T03, # import yaml (will be converted to json), # if the js file evaluates to a function, it can be re-used later using the 'call' keyword (or invoked just like normal js), # the following short-cut is also allowed, # perfect for all those common authentication or 'set up' flows, And request karate.readAsString('classpath, # use only 'ssim' (structural similarity) engine, # always use both 'resemble' and 'ssim' engines but only evaluate the lowest mismatch percentage against our `failureThreshold`, # prefer 'resemble' and fallback to 'ssim' engine only if the resemble mismatch percentage is >= `failureThreshold`, # only consider the comparison as failed when 2% or more pixels are different from the baseline, * configure imageComparison = { failureThreshold, # consider image comparisons that fail due to too many mismatched pixels as passed (especially useful when you are first starting without any baseline images), * configure imageComparison = { mismatchShouldPass, # custom JS function called in Karate HTML image comparison UI when the user clicks the `Rebase` button, """ Re-use can sometimes result in negative benefits - especially when applied to test-automation. So in dev mode you can easily set this behavior like this. 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. There is also a karate.mapWithKey() for a common need - which is to convert an array of primitives into an array of objects, which is the form that data driven features expect. Standard JavaScript syntax rules apply, but the right-hand-side should begin with the function keyword if declared in-line. A stand-alone example can be found here: examples/image-comparison along with a video explanation. Also see the option below, where you can data-drive an Examples: table using JSON. In real-life scripts, you would typically also use this capability of Karate to configure headers where the specified JavaScript function uses the variables that result from a sign in to manipulate headers for all subsequent HTTP requests. The response is automatically available as a JSON, XML or String object depending on what the response contents are. Requirement: Open a feature file in VSCode Editor and ensure a line associated with a test has cursor focus. Karate supports JUnit 5 and the advantage is that you can have multiple methods in a test-class. . if so, is the configured value a JavaScript function ? Also refer to the eval keyword for a simpler way to execute arbitrary JavaScript that can be useful in some situations. And if you have a Scenario Outline, this happens for every row in the Examples. Refer to this demo feature for an example: kitten-create.feature. "a": 1, In fact, this is the mechanism used when karate-config.js is processed on start-up. input: One workaround is to temporarily disable or rename your Maven settings.xml file, and try again. The variable state after feature execution would be returned as a Map. env which is a global variable. Refer to your IDE documentation for how to run a JUnit class. For manipulating or updating JSON (or XML) using path expressions, refer to the set keyword. And karate.appendTo() is for updating an existing variable (the equivalent of array.push() in JavaScript), which is especially useful in the body of a karate.forEach(). A very rare need is to be able to convert a string which happens to be in YAML form into JSON, and this can be done via the yaml type cast keyword. Open a feature file after you have installed the plug-in. You usually wont need this, but the second-last line above shows how the karate object can be used to evaluate JsonPath if the filter expression depends on a variable. These examples (all exact matches) can make things more clear: Note that you can alternatively use JsonPath on the left-hand-side: But of course it is preferable to match whole objects in one step as far as possible. { all You can change the com.intuit.karate logger level to INFO to reduce the amount of logging. This tag selection capability is designed for you to be able to compose flows out of existing test-suites when using the Karate Gatling integration. before you fire the method. top: 483, 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. Each functionality of the software must have a separate feature file. Technical Info #Pack-BIP ID: BIP-Walk-Pack. Setting values on JSON documents is simple using the set keyword. The following parameters are supported: For end-to-end examples in the Karate demos, look at the files in this folder. When multipart content is involved, the Content-Type header of the HTTP request defaults to multipart/form-data. Paste the raw data in textbox. String interpolation will support variables in scope and / or the Examples (including functions defined globally, but not functions defined in the background). The keywords Given When Then are only for decoration and should not be thought of as similar to an if - then - else statement. So you could have also done something like: Also refer to the configure keyword on how to switch on pretty-printing of all HTTP requests and responses. JsonPath filter expressions are very useful for extracting elements that meet some filter criteria out of arrays. response is a built-in variable in karate that stores HTTP API response. Since asserting against header values in the response is a common task - match header has a special meaning. Mocks writing. The following short-cut is also supported which will disable all logs: When you use a re-usable feature that has commonly used utilities, you may want to hide this completely from the HTML reports. So you can do things like right-click and run a *.feature file (or scenario) without needing to use a JUnit runner. Normally we recommend that you keep your re-usable features lightweight - by limiting them to just one Scenario. The above example can be made more simpler with the use of call (or callonce) without a def-assignment to a variable, and is the recommended pattern for implementing re-usable authentication setup flows. countryName: '#string', Go to Folder src/test/java in your project.Creating The First Basic Karate Test Script. The @setup tag is built-in for this purpose and any Scenario tagged with this will behave like @ignore. if you acquired a string from some external source, or if you generated JSON (or XML) by concatenating text or using replace, you may want to convert a string to JSON and vice-versa. Also note that multipart file takes a JSON argument so that you can easily set the filename and the contentType (mime-type) in one step. You can skip this section and jump straight to the Syntax Guide if you are in a hurry to get started with Karate. Another good thing that Karate inherits is the nice IDE support for Cucumber that IntelliJ and Eclipse have. This will create a folder called myproject (or whatever you set the name to). karate.set('temp', squares); It may be easier for you to use the Karate Maven archetype to create a skeleton project with one command. REST API request testing. """, # optional (can be null) and if present should be an array of size greater than zero, # should be an array of size equal to $.count, # use a predicate function to validate each array element, # if you prefer using 'pure' JsonPath, you can do this, # using the karate object if the expression is dynamic, """ Run All Karate Tests. Mac: Cmd+V. 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. * match response contains only deep { foo, # and you can use 'contains' the way you'd expect, # some more examples of validation macros, # this is also possible, see the subtle difference from the above, """ ; OpenAPI Generator that generates: . 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). A very useful capability is to be able to check that an array contains an object that contains the provided sub-set of keys instead of having to specify the complete JSON - which can get really cumbersome for large objects. Note how we unpack the kittens and use it to data drive the Scenario Outline. But this totally makes sense for things not part of the main test flow and which typically need to be re-usable anyway. As a convenience, cookies from the previous response are collected and passed as-is as part of the next HTTP request. So you get the picture, any kind of complicated sign-in flow can be scripted and re-used. The approach in this section is more suited for troubleshooting in dev-mode, using your IDE. 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. And similarly - for specifying the HTTP proxy. Short story taking place on a toroidal planet or moon involving flying, Doesn't analytically integrate sensibly let alone correctly, Full text of the 'Sri Mahalakshmi Dhyanam & Stotram', Equation alignment in aligned environment not working properly. Expect to spend $20 to $45 per square foot for a custom job. ] The main island is separated from Peninsular Malaysia to the north by Johor Strait, a narrow channel crossed by a . This will give you the usual HTML report showing what features will be run, including all steps shown (including comments) so that it can be reviewed. If you are trying to build dynamic URLs including query-string parameters in the form: http://myhost/some/path?foo=bar&search=true - please refer to the param keyword. } What this means is that you are free to use whatever makes sense for you. Now, lets continue with the variables in Karate. There are examples of calling JVM classes in the section on Java Interop and in the file-upload demo. Scenario: creating a repo and verifying the response * path '/user/repos' #Change the repo_name . For placeholder-substitution, the replace keyword can be used instead, but with the advantage that the text can be read from a file or dynamically created. You can also re-use other *.feature files from test-scripts: When a called feature depends on some side-by-side resources such as JSON or JS files, you can use the this: prefix to ensure that relative paths work correctly - because by default Karate calculates relative paths from the root feature or the top-most caller. """, # normal 'equality' match. Naturally, only one value can be returned. Something like this: For HTTPS / SSL, you can also specify a custom certificate or trust store by setting Java system properties. 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. Refer to the cats-java.feature demo for an example. After you define the URL, you need to define a path to send a request. So if you tried to re-use the same feature but with multiple arguments, things will not work as you expect. Internally, Karate will auto-convert JSON (and even XML) to Java Map objects. And as a testing framework, Karate discourages tests that give different results on every run. By default, Karate will load all *.feature files from sub-directories as well. Of course it is an option to have Karate tests in a separate stand-alone maven project and folder, while still being in the same Git repository. Just like yaml, you may occasionally need to convert a string which happens to be in CSV form into JSON, and this can be done via the csv keyword. Refer to this case study for how dramatic the reduction of lines of code can be. The first four below are best explained in this example file: type-conv.feature. Any Karate expression can be used in the cell expression, and you can even use Java-interop to use external data-sources such as a database. Now it should be clear how Karate makes it easy to express JSON or XML. You need to be familiar with Karate in order to understand the Calling Custome Java Code in Karate API Teststutorial. Since Karate uses Gherkin, you can also employ data-driven techniques such as expressing data-tables in test scripts. Karate gives us lots of options to work with data. "arr": [ 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). It begins with the Feature keyword, followed by the . Linux: Ctrl+Shift+R+1. This is great for testing boundary conditions against a single end-point, with the added bonus that your test becomes even more readable. #10, #15: There must be a structure expected as a response of the API. Is there a way to run a single scenario defined into a feature? And if you do this within a Background: section, it would apply to all Scenario: sections within the *.feature file. Try this especially if you dont have much experience with programming or test-automation. It is worth taking a few minutes to go through the documentation and examples here: JsonPath Examples. You can always use a JavaScript function or call Java for more complex logic. This approach can certainly enable product-owners or domain-experts who are not programmer-folk, to review, and even collaborate on test-scenarios and scripts. Load testing. Passing data from one feature file to another is very common requirement when it comes to automation. It gets the value of any Java system-property by name. You can use karate.callSingle() directly in a *.feature file, but it logically fits better in the global bootstrap. You can see what the result looks like here. Use the comma-delimited form (see above) or the JS helper (see below). Reading files is achieved using the built-in JavaScript function called read(). The demo also features code-coverage using Jacoco, and some tips for even non-Java back-ends. Here below is an example jbang script that uses the Karate Java API to do some useful work. JSON arrays), see. countryId: '#number', This means that even when you have dynamic server-side generated values such as UUID-s and time-stamps appearing in the response, you can still assert that the full-payload matched in one step. Note that regex escaping has to be done with a double back-slash - for e.g: '#regex a\\.dot' will match 'a.dot'. For completeness, the built-in tags are the following: There are two special tags that allow you to select or un-select a Scenario depending on the value of karate.env. 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. Gherkin has a great way to sprinkle meta-data into test-scripts - which gives you some interesting options when running tests in bulk. You can re-use the function you create across your whole project. data: { Create util.DbUtils java class and add the following java code snippet. What is even more interesting is that expressions can refer to variables: And functions work as well ! Note that a single JS function is sufficient to transform a given JSON object into a completely new one, and you can use complex conditional logic if needed. The recommended approach for Karate reporting in a Continuous Integration set-up is described in the next section which can generate the JUnit XML format that most CI tools can consume. To run only a single scenario, append the line number on which the scenario is defined, de-limited by :. Now, run the TestRunner and observe that you would not find all the verbose logs in console which you were getting before and rather it would be saved in a file karate.log under target folder . Behaves the same way as the. If youre looking for more complex ways of dynamically naming your scenarios you can use JS string interpolation by including placeholders in your scenario name. 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. 1234 If you are a Java developer - Karate requires at least Java 8 and then either Maven, Gradle, Eclipse or IntelliJ to be installed. The karate-chrome Docker is an image created from scratch, using a Java / Maven image as a base and with the following features: Chrome in "full" mode (non-headless) Chrome DevTools protocol exposed on port 9222. Karate is flexible, you can easily over-write config variables within the Java or JUnit runner - which is very convenient when in dev-mode or rapid-prototyping. 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. or anything wrapped in parentheses which will be evaluated as JavaScript - e.g. The results of the first call are cached, and any future calls will simply return the cached result instead of executing the JavaScript function (or feature) again and again. While this sounds dangerous and should be used with care (and limits readability), the reason this feature exists is to quickly set (or over-write) a bunch of config variables when needed. 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. put a tag called, How Intuit democratizes AI development across teams through reusability. Singapore, city-state located at the southern tip of the Malay Peninsula, about 85 miles (137 kilometres) north of the Equator. and & will be automatically inserted. Something worth mentioning here is that you would hardly need to use assert in your test scripts. A Karate test script has the file extension .feature which is the standard followed by Cucumber. Calling any Java code is that easy.
