var JavaDemo = Java.type('com.mycompany.JavaDemo'); 1+ years experience with Jira . Also see this explanation. API tests are written in BDD (Behaviour Driven Development) Using Gherkin syntax. or is the configured value a JSON object ? 1234 This is exactly like match == but the order of arrays does not matter. You can always use a JavaScript switch case within an eval or function block. 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 even tags to exclude (or include) can be specified: Note that any Feature or Scenario with the special @ignore tag will be skipped by default. Get all my courses for USD 5.99/Month - https://bit.ly/all-courses-subscriptionIn this Karate Tutorial, we will learn about webelement functions in Karate, l. Note that #present and #notpresent only make sense when you are matching within a JSON or XML context or using a JsonPath or XPath on the left-hand-side. If you read from a file, the advantage is that multiple scripts can re-use the same data. Note that even the scenario name can accept placeholders - which is very useful in reports. Navigates to a new page / address. ", Karate will wrap the function for you ! Some third-party report-server solutions integrate with Karate such as ReportPortal.io. Combined with Docker, headless Chrome and Karates parallel-execution capabilities - this simple start() and stop() lifecycle can effectively run web UI automation tests in parallel on a single node. Sometimes, because of an HTTP re-direct, it can be difficult for Karate to detect a page URL change, or it will be detected too soon, causing your test to fail. Things are designed so that you can plug-in what you need, without needing to compile Java code. } 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). Custom header manipulation for every HTTP request is something that Karate makes very easy and pluggable. Use it sparingly, and only for string, number or simple payload comparisons. Also see type conversion. Use a variable in the called feature instead, for e.g. Also see waits. { This will also do automatically perform a karate.embed() - so that the image appears in the HTML report. One indicator of a good automation framework is how much work a developer needs to do in order to perform any automation action - such as clicking a button, or retrieving the value of some HTML object / property. The default is 30000 (30 seconds). Get the outerHTML, so will include the markup of the selected element. Ping me Now! You dont have to compile code. But again, you can return a JSON object. 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. Since replace auto-converts the result to a string, make sure you perform type conversion back to JSON (or XML) if applicable. Tech, Java, IT Project Manager. And each element of the returned array will be the envelope of variables that resulted from each iteration where the *.feature got invoked. An image comparison UI will also be embedded into the Karate HTML report with detailed information about any differences between the two images. { Just write tests in a simple, readable syntax - carefully designed for HTTP, JSON, GraphQL and XML. Take a look at how the configure headers example uses the authToken variable. Keywords such as set and remove allow you to to tweak payload-data to fit the scenario under test. This should make it clear why Karate does not provide out of the box support for any particular HTTP authentication scheme. For another example, see: examples.feature. You can over-ride it by using the header keyword before the method step. 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. Of course, resorting to a sleep in a UI test is considered a very bad-practice and you should always use retry() instead. For example: As seen above, you dont have to force all your steps to use the Given, When, Then BDD convention, and you can just use * instead. When using call (or callonce), only one argument is allowed. When using Playwright you can omit this in which case Karate will default to Chrome (within Playwright) and the default browser window size. {2}', id: '#uuid' }, # convenient (and recommended) way to check for array length, # here we enclose in round-brackets to preserve the optional embedded expression, # so that it can be used later in a "match", """ Refer to the demos for another example: soap.feature. API testing basics and Karate framework 2. 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. { A common need is to move (or hover) the mouse, and for this you call the move() method. } Step 3: Add steps to run a sample POST API request. """, # use dynamic path expressions to mutate json, * def filename = zone == 'zone1' ? Here are some examples: Take a look at how to loop and transform data for more ideas. Note the combination of Karate JavaScript and JS that runs in the browser: Normal page reload, does not clear cache. If you find yourself juggling multiple tags with logical AND and OR complexity, refer to this Stack Overflow answer. Hello World Index Capabilities Simple, clean syntax that is well suited for people new to programming or test-automation All-in-one framework that includes parallel-execution, HTML reports, environment-switching, and CI integration This can be really convenient, for example to never run some tests in a certain production like or sensitive environment. """, * configure imageComparison = { onShowConfig, # don't embed the image comparison UI when the latest image is the same / similar to the baseline (e.g. All the methods that return the following Java object types are chain-able. Theres a lot going on in the last line above ! : * param myparam = 'value' or url: * url 'http://example.com/v1?myparam'. Another good thing that Karate inherits is the nice IDE support for Cucumber that IntelliJ and Eclipse have. Behind the scenes, this sets the HTTP communication read timeout. Karate creates a new context for the feature file being invoked but passes along all variables and configuration. 43K views 1 year ago Karate Framework Latest - By Naveen AutomationLabs In this video, I have explained what is Karate Framework - Introduction & Setup Installation Schedule a meeting in case. One example of when you may want to convert JSON (or XML) to a string is when you are passing a payload to custom code via Java interop. karate.set('temp', squares); You can lock down the fact that you only want to execute the single JUnit class that functions as a test-suite - by using the following maven-surefire-plugin configuration: Note how the karate.options can be specified using the configuration. For example, it offers API testing, API testing doubles, and API performance testing all in one framework. bar: 'world' Note that the karate-config.js is re-processed for every Scenario and in rare cases, you may want to initialize (e.g. But note that ##null can be used to represent a convention that many teams adopt, which is that keys with null values are stripped from the JSON payload. right: 1496 The answer is no. Just like script(), but will perform the script eval() on all matching elements (not just the first) - and return the results as a JSON array / list. In some rare cases where you dont want to auto-convert JSON, XML, YAML or CSV, and just get the raw string content (without having to re-name the file to end with .txt) - you can use the karate.readAsString() API. Because of how easy it is to set HTTP headers, Karate does not provide any special keywords for things like the Accept header. Karate is a great fit for testing GraphQL because of how easy it is to deal with dynamic and deeply nested JSON responses. This means that you cannot use any Karate JS objects or API-s such as karate.get() or driver.title. It is a great example of how to effectively use the unique combination of Cucumber and JsonPath that Karate provides. As a short-cut, when running JsonPath expressions - $ represents the response. 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 ! You can then skip the next few sections, as the pom.xml, recommended directory structure, sample test and JUnit 5 runners - will be created for you. To understand how Karate compares to other UI automation frameworks, this article can be a good starting point: The world needs an alternative to Selenium - so we built one. Note how karate.set() and karate.remove() below are used directly as a script statement. 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. Step 3: Create a feature file and write a Scenario. ] This is optional, and Karate will work without the logging config in place, but the default console logging may be too verbose for your needs. The function argument is the row-index, so you can easily determine when to stop the generation of data. Yes, you can modify the request or response if needed ! Another example for a popular Maven reporting plugin that is compatible with Karate JSON is Cluecumber. Although it is just a few lines of code, take time to study the above example carefully. Do note that if you prefer a pure Java API - Karate has that covered, and with far more capabilities. And this assertion will cause the test to fail if the HTTP response code is something else. And there is another example in the karate-demos: schema.feature where you can compare Karates approach with an actual JSON-schema example. * 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, """ The most important part of this payload is the capabilities. But this time, the return value from the call step will be a JSON array of the same size as the input array. foo: 'hello', Karate has enhanced the Cucumber Scenario Outline as follows: These are best explained with examples. Here is a real-life example combined with the use of retry(): If you have more than two locators you need to wait for, use the single-argument-as-array form, like this: Returns an Element (instead of exists() which returns a boolean). From a file in the same package. We even slip in a page-URL assertion without missing a beat. This can be convenient if a particular call results in a huge response payload. For example, see the sayHelloFactory() method below: And now, to get a reference to that function you can do this: This can be convenient when using shared scope because you can just call sayHello('myname') where needed. Since it is internally implemented as a JavaScript function, you can mix calls to read() freely wherever JavaScript expressions are allowed: Tip: you can even use JS expressions to dynamically choose a file based on some condition: * def someConfig = read('my-config-' + someVariable + '.json'). The syntax is similar to def but instead of a named variable, you update configuration. You can adjust configuration settings for the HTTP client used by Karate using this keyword. The need to wait until some text appears is so common, and with this - you dont need to worry about dealing with white-space such as line-feeds and invisible tab characters. Multiple fields can be set in one step using multipart fields. status: '#number? function(arg) { In most cases you wont need to set the Content-Type header as Karate will automatically do the right thing depending on the data-type of the request. The section on Karate Expressions goes into the details. In this 2-hour long project-based course, you will learn -- 1. You should be able to run tests in parallel with ease ! You can see a demo video here. On the other hand, if you are expecting a variable in the Background to be modified by one Scenario so that later ones can see the updated value - that is not how you should think of them, and you should combine your flow into one scenario. Even though Wikipedia says "web-API", it can do web UI . 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. This can be a lot simpler than embedded expressions in many cases, and JavaScript programmers will feel right at home. var foo = function(v){ return v * v }; How To Scroll Into View in Selenium Webdriver, How To Solve IllegalStateException in Selenium WebDriver. Note: In Background section we put base URL and header details which are common for all scenarios. And as a convenience, whatever object is returned, can be re-used in future steps. And creating tests may actually turn out to be fun ! Also refer to the eval keyword for a simpler way to execute arbitrary JavaScript that can be useful in some situations. """, # 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, """ // trigger download of latest image with custom file name Karate Labs is an industry leading open-source test automation solution unifying API & UI test automation. 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. function (customConfigJson, config) { 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. Just re-fresh your browser window if you re-run the test. 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. 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. For a proxy that requires authentication, set the, The charset that will be sent in the request, HTTP requests and responses (including headers) will appear in the HTML report, default. # but using karate.range() you can even do this ! Full Time position. Get method in HTTP is used to read or access data or information. Note that you can even include calls to a database from Karate using Java interop. As a convenience, there is a second form where you can pass an array as the second argument: And an extra convenience third argument is a time-delay (in milliseconds) that will be applied before each array value. Also see first.feature and second.feature in the demos. There are examples of calling JVM classes in the section on Java Interop and in the file-upload demo. And you dont need to create additional Java classes for any of the payloads that you need to work with. The listenResult magic variable will hold the value passed to the call to karate.signal(). The set of built-in functions that start with wait handle all the cases you would need to typically worry about. In rare cases you may need to set a variable from this routine, and a good example is to make the generated UUID visible to the currently executing script or feature. It will be initialized only after the driver keyword has been used to navigate to a web-page (or application). It is based on Cucumber and uses the Gherkin Syntax. 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. 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: ~~. Karate is the only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. the NOT operator e.g. Karate and BDD Karate is built on top of Cucumber, another BDD testing framework, and shares some of the same concepts. The BDD syntax with Cucumber is launguage neutral, and easy for even non-programmers. It can also be argued that the # symbol is easy to spot when eyeballing your test scripts - which makes things more readable and clear. useful to scrape text out of non-JSON or non-XML text sources such as HTML, like the above, but returns a list of text-matches. Karate supports JUnit 5 and the advantage is that you can have multiple methods in a test-class. If you want to point to a real file, use the file: prefix. Use the webDriverSession property in those cases. 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. function fn(x){ return x + 1 }. This does the same thing as the timeout key in the driver config - but is designed so that you can change this on the fly, during the flow of a test. You can organize multiple common utilities into a single re-usable feature file as follows e.g. It is worth mentioning that to do the equivalent of the last line in Java, you would typically have to traverse 2 Java Objects, one of which is within a list, and you would have to check for nulls as well. Finally, the page is updated to display the first-name, last-name and the image. You also have the option of setting multiple cookies in one-step using the cookies keyword. By now, it should be clear that JsonPath can be very useful for extracting JSON trees out of a given object. When eyeballing a test-script, think of the * as a bullet-point. In the feature below, the * print 'in setup' step will run only once. The Karate regression test-suite that runs in GitHub actions (effectively our CI) - includes another example, and you can find a good explanation here. And this framework is the only API testing tool that has combined API Automation and performance testing into a single standalone tool. This is easily achieved with the karate.repeat() API: And theres also karate.range() which can be useful to generate test-data. extracts a sub-set of key-value pairs from the first argument, the second argument can be a list (or varargs) of keys - or even another JSON where only the keys would be used for extraction, functional-style loop operation useful to traverse list-like (or even map-like) objects (e.g. } To run only a single scenario, append the line number on which the scenario is defined, de-limited by :. 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. Of course the actual time-durations, and logs will be missing, and everything will pass. This means that you can combine them to concisely express certain types of intent - without having to repeat the locator. For advanced examples, refer to some of the scenarios within this demo: dynamic-params.feature. You can do this. The method signature of the assertTrue has flipped around a bit. For tests that need to wait for slow pages or deal with un-predictable element load-times or state / visibility changes, Karate allows you to temporarily tweak the internal retry settings. A Java API also exists for those who prefer to programmatically integrate Karates rich automation and data-assertion capabilities. It is always start with Question mark (?). Make sure you call go() at the end - if the last method in the chain is not click() or up(). More examples of Java interop and how to invoke custom code can be found in the section on Calling Java. 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.
