Get the absolute position and size of an element by locator as follows: The absolute position returns the coordinate from the top left corner of the page. 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. JSON arrays), see. But always use the driver keyword when you start a test and you can choose to prefer that shorter form in general. Only supported for driver type android | ios, for hiding the soft keyboard. Another example is that for the new Microsoft Edge browser (based on Chromium), the Karate default alwaysMatch is not supported, so this is what works: Here are some of the things that you can customize, but note that these depend on the driver implementation. function(x, y, i) { Final word, Bookmark this post Karate Frameworkfor future reference. Name the file as javadsl.java and run using the command: jbang javadsl.java. Also refer to the wiki for using Karate with Gradle. JsonPath filter expressions are very useful for extracting elements that meet some filter criteria out of arrays. And if being called in a loop, a built-in variable called __loop will also be available that will hold the value of the current loop index. REST-style path parameters. Example: In an application testing if we are login the application in each scenario then we can put the login scenario under background. The final piece of the puzzle is to set up a batch file to start the server: The exec is important here so that Karate can stop the node process cleanly. So trying to use driver.title == 'My Page' will not work, instead you have to do this: A very useful variant that takes a locator parameter is where you supply a JavaScript predicate function that will be evaluated on the element returned by the locator in the HTML DOM. As you can imagine, this can handle un-predictable dialogs, advertisements and the like. He created Karate to address some of the issues of Selenium. Note that def will over-write any variable that was using the same name earlier. When a constant value keeps on repeating replace it with a variable. Here is an example: Rarely used, but when you want to just instantiate an Element instance, typically when you are writing custom re-usable functions, or using an element as a waypoint to access other elements in a large, complex tree. File-upload is supported natively only by type: chrome. The keywords def, set, match, request and eval take multi-line input as the last argument. You can potentially include the steps of deploying (and un-deploying) the application-under-test using this approach - but probably the top-level JUnit test-suite would be the right place for those. And the right-hand-side can be any valid Karate expression. For more details check this link- Embedded Expression. This will wait until the element (by locator) is present in the page and uses the configured retry() settings. And path blog?page=2. 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. By default, the value of karate.env when you access it within karate-config.js - would be null. """, # note how we returned an array from the above when the condition was met, # and now we can use the results like normal. 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. But we recommend that you do this only if you are sure that these routines are needed in almost all *.feature files. German or ISO-8859-15. note the wildcard '*' in the JsonPath (returns an array), # when inspecting a json array, 'contains' just checks if the expected items exist, # and the size and order of the actual array does not matter, # the .. operator is great because it matches nodes at any depth in the JSON "tree". As a convenience, cookies from the previous response are collected and passed as-is as part of the next HTTP request. 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. when a string coming from an external process is dynamic - and whether it is JSON or XML is not known in advance, see, get the value of a variable by name (or JsonPath expression), if not found - this returns, returns only the keys of a map-like object, log to the same logger (and log file) being used by the parent process, logging can be suppressed with, access to the Karate logger directly and log in debug. And with the its latest update, Karate also supports UI test automationmaking it a true, end-to-end unified testing framework . For suppressing sensitive information such as secrets and passwords from the log and reports, see Log Masking and Report Verbosity. For example if you have HTML like this: To click on the checkbox, you just need to do this: By default, the HTML tag that will be searched for will be input. The Runner.Builder API has a dryRun() method to switch this on. Also make sure that you complete the set up of things like url, param, header, configure etc. Here are some examples: Take a look at how to loop and transform data for more ideas. Also see this thread. It is a great example of how to effectively use the unique combination of Cucumber and JsonPath that Karate provides. Make sure you configure your source code management system (e.g. 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. Any valid XPath expression is allowed on the left-hand-side of a match statement. You can replace the values of com.mycompany and myproject as per your needs. Although all properties in the passed JSON-like argument are unpacked into the current scope as separate named variables, it sometimes makes sense to access the whole argument and this can be done via __arg. Full Time position. If the second HTTP call above expects headers to be set by my-headers.js - which in turn depends on the authToken variable being updated, you will need to duplicate the line * configure headers = read('classpath:my-headers.js') from the caller feature here as well. So how can you get this value injected into the Karate configuration ? # but karate allows you to traverse xml like json !! """, # attempt to detect and ignore antialiasing, # customize color / brightness tolerances, # switch to `original` grayscale SSIM algorithm, # JS math can introduce a decimal point in some cases, # but you can easily coerce to an integer if needed, # or you can do the same on multiple lines if you wish, # set headers or params (if any) BEFORE the method step. For manipulating or updating JSON (or XML) using path expressions, refer to the set keyword. See karate.callSingle(). function() { id: 1, You just need to do a normal POST (or GET). Also refer to this demo example for a working example of multipart file uploads: upload.feature. And this framework is the only API testing tool that has combined API Automation and performance testing into a single standalone tool. The syntax is easy to understand by non-programmers. can be specified like this: A special variable called Key will be available and you can see all the possible key codes here. } The advantage of this approach is that it works with any of the actions. A variation where the argument is JSON instead of a URL / address-string, used typically if you are testing a desktop (or mobile) application. Notice how once the authToken variable is initialized, it is used by the above function to generate headers for every HTTP call made as part of the test flow. Note that Karate has built-in support for CSV files and here is an example: dynamic-csv.feature. playwright) for the start scripts to live. One way to define test-suites in Karate is to have a JUnit class at a level above (in terms of folder hierarchy) all the *.feature files in your project. for (var n in nums) { Since Karate uses Gherkin, you can also employ data-driven techniques such as expressing data-tables in test scripts. Alternatively, if using Gradle then add the following sourceSets definition. But even if you use {*} (or {} which is the equivalent short-cut) to match any tag, you are selecting based on what the user sees on the page. Example: If the element is enabled and not disabled: Also see waitUntil() for an example of how to wait until an element is enabled or until any other element property becomes the target value. The example below combines this with the advanced features described above. These are built-in variables, there are only a few and all of them give you access to the HTTP response. After every HTTP call this variable is set with the response body, and is available until the next HTTP request over-writes it. ] The mouse().move() method has two forms. var date = new java.util.Date(); The demo also features code-coverage using Jacoco, and some tips for even non-Java back-ends. Since replace auto-converts the result to a string, make sure you perform type conversion back to JSON (or XML) if applicable. or is the configured value a JSON object ? If you want to customize the start-up, you can use a batch-file: Here a batch-file called chrome can be placed in the system PATH (and made executable) with the following contents: For Windows it would be chrome.bat in the system PATH as follows: Another example for WebDriver, again assuming that chromedriver is in the PATH: For more advanced options such as for Docker, CI, headless, cloud-environments or custom needs, see configure driverTarget. And Karate gives you control over these aspects with the small set of keywords focused on HTTP such as url, path, param, etc. 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). """, # note the 'text' keyword instead of 'def', """ { id: { domain: "DOM", type: "entityId", value: "#ignore" }, Using locators in Karate UI Web Automation There are various ways we can locate an element in Karate. And there is no more worrying about Maven profiles and whether the right *.properties file has been copied to the proper place. multipart file uploads can be tricky, and hard to get right. kittens: [ A common requirement is to build an array with n elements or do something n times where n is an integer (that could even be a variable reference). It works with Gherkin language, and It is easy for even non-programmers. Although it is just a few lines of code, take time to study the above example carefully. 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. This provides the following methods: In any complex testing endeavor, you would find yourself needing common code that needs to be re-used across multiple test scripts. """, # 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, """ It is worth internalizing that during test-execution, it is upon the method keyword that the actual HTTP request is issued. But you can easily achieve any complex logic by using the JS API. auth tokens) only once for all of your tests. 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. Other errors could be a java.net.URISyntaxException and match not working as expected because of special or foreign characters, e.g. created: { on: "#ignore" }, The karate-chrome Docker is an image created from scratch, using a Java / Maven image as a base and with the following features: To try this or especially when you need to investigate why a test is not behaving properly when running within Docker, these are the steps: For more information on the Docker containers for Karate and how to use them, refer to the wiki: Docker. It so happens that the karate object has a field called properties which can read a Java system-property by name like this: karate.properties['myName']. Instead you would typically use the match keyword, that is designed for performing powerful assertions against JSON and XML response payloads. a sibling Docker container or a Chrome browser in a different machine) you might need to configure DockerTarget with the remoteHost and/or useDockerHost properties. Karate was based on Cucumber-JVM until version 0.8.0 but the parser and engine were re-written from scratch in 0.9.0 onwards. This example is for Windows, and you can provide the app, appArguments and other parameters expected by the WinAppDriver via the webDriverSession. id: 1 You can even create (or modify existing) JSON arrays by using multiple columns. { "roomInformation": [{ "roomPrice": 679.79}], "totalPrice": 679.79 } This is very useful to filter the results that match a desired condition - typically a text comparison. When JavaScript executes in Karate, the built-in karate object provides some commonly used utility functions. And path blog To support all the various options such as Docker, headless Chrome, cloud-providers etc., Karate introduces the concept of a pluggable Target where you just have to implement two methods: start(): The Map returned will be used as the generated driver configuration. For example: And similarly for XML and XPath, / represents the response. } Listing for: Cognizant United States, Cognizant Technology Solutions. leagueName: '##string', } They should be at the end of the karate.options. The Karate project team is of the opinion that things can be made simpler. This is especially useful when you want to maintain passwords, secrets or even URL-s specific for your local dev environment. That said, the syntax is very concise, and the convention of every step having to start with either Given, And, When or Then, makes things very readable. 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. You should be able to run tests in parallel with ease ! Another (simple) example of a custom Target you can use as a reference is this one: karate-devicefarm-demo - which demonstrates how Karate can be used to drive tests on AWS DeviceFarm. This is the recommended, browser-agnostic approach that uses Karates core-competency as an HTTP API client i.e. Step 1: Create a feature file under src > test > java folder. Another good thing that Karate inherits is the nice IDE support for Cucumber that IntelliJ and Eclipse have. This is what is normally expected and simulates a web-browser - which makes it easy to script things like HTML-form based authentication into test-flows. Uses the configured highlightDuration. Of course, try not to use single-quotes within the string to be matched, or escape them using a back-slash (\) character. locateAll() can take a second argument which has to be a JavaScript predicate function, that returns a boolean true or false. 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. Here is an example of waiting for a search box to appear after a click(), and note how we re-use the Element reference returned by waitFor() to proceed with the flow. When you use a JUnit runner - after the execution of each feature, an HTML report is output to the target/karate-reports folder and the full path will be printed to the console (see video). 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. This means that you can combine them to concisely express certain types of intent - without having to repeat the locator. 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. Other UI automation frameworks spend a lot of time encouraging you to follow a so-called Page Object Model for your tests. Refer to the documentation on type-conversion to make sure you can unpack data returned from Karate correctly, especially when dealing with XML. You should take a minute to compare this with the exact same example implemented in REST-assured and TestNG. What is even more interesting is that expressions can refer to variables: And functions work as well ! The syntax is similar to def but instead of a named variable, you update configuration. bar: 'world' For convenience, some stats are logged to the console when execution completes, which should look something like this: The parallel runner will always run Feature-s in parallel. Normally we recommend that you keep your re-usable features lightweight - by limiting them to just one Scenario. It returns the Element representation of whichever element was found first, so that you can perform conditional logic to handle accordingly. Based on the above details, you should be able to come up with a custom strategy to connect Karate to Playwright. Also see waits. If you want to perform API testing but you dont have knowledge of any programming language then you should choose Karate framework to perform API testing. """, # * match cat == { name: '#ignore', type: '#regex . Valid options are, The number of bits used to encode each pixel, The maximum size on the smallest dimension before downsampling. Refer to this demo feature for an example: kitten-create.feature. And there is another example in the karate-demos: schema.feature where you can compare Karates approach with an actual JSON-schema example. But if you need to use values in the response headers - they will be in a variable named responseHeaders. Format of the keyStore file. { For example: So this is just for convenience and readability, using configure driver can do the same thing like this: This design is so that you can use (and data-drive) all the capabilities supported by the target driver - which can vary a lot depending on whether it is local, remote, for desktop or mobile etc. 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. 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. Note that there is a top-level config flag for headless mode. The same approach should apply to any Selenium grid provider such as Zalenium. If you really need to re-use a Java function, see Java Function References. Refer to the cats-java.feature demo for an example. All you need is available in the karate-core artifact. If you use the provided ScenarioRuntime.logger instance in your Target code, any logging you perform will nicely appear in-line with test-steps in the HTML report, which is great for troubleshooting or debugging tests. Separate Scenario-s that can run in parallel are encouraged. Note how we can even serve an image with the right Content-Type header. params, headers, cookies, form fields, multipart fields and multipart files take a single JSON argument (which can be in-line or a variable reference), and this enables certain types of dynamic data-driven testing, especially because any JSON key with a null value will be ignored. 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. Note that there is a karate.fail() API that may be handy when you want to fail a test after advanced / conditional checks. A callonce is ideally used for only pure JSON. 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. In such cases, you can use waitForUrl(). function(s) { The Karate regression test-suite that runs in GitHub actions (effectively our CI) - includes another example, and you can find a good explanation here. In case you were wondering, variables (and even expressions) are supported on the right-hand-side. You can even perform a conversion from XML to JSON if you want. Here is a summary: Note that for the afterFeature hook to work, you should be using the Runner API and not the JUnit runner. get metadata about the currently executing feature within a test, functional-style filter operation useful to filter list-like objects (e.g. function (config, downloadLatestFn) { ] Note that even the scenario name can accept placeholders - which is very useful in reports. In the called feature, the argument can also be accessed using the built-in variable: called Karate scripts dont need to use any special keywords to return data and can behave like normal Karate tests in stand-alone mode if needed, the data return mechanism is safe, there is no danger of the called script over-writing any variables in the calling (or parent) script (unless you use, the need to explicitly unpack variables by name from the returned envelope keeps things readable and maintainable in the caller script, call re-usable functions that take complex data as an argument and return complex data that can be stored in a variable, JavaScript / JSON-style mutation of existing. And thats all there is to Karate configuration ! A few more useful transforms are to select a sub-set of key-value pairs using karate.filterKeys(), merging 2 or more JSON-s using karate.merge() and combining 2 or more arrays (or objects) into a single array using karate.append(). 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. While $ always refers to the JSON root, note the use of _$ above to represent the current node of a match each iteration. 1. The following scenario will make this clear. You are free to organize your files using regular Java package conventions. 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. There are two things that can happen to the returned value. Karate an Open source framework developed by Karatelabs has made Test Automation simple and unified for both API testing and UI Automation using Gherkins. You may face issues if you attempt to mix in JS functions or Java code. please replace RELEASE with the exact version of Karate you intend to use if applicable. The recommendation is that you prefer chrome for development, and once you have the tests running smoothly - you can switch to a different WebDriver implementation. 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. Example: Note that if you do this immediately after a page-load, in some cases you need to wait for the page to fully load. That said, there is some benefit to re-use of just locators and Karates support for JSON and reading files turns out to be a great way to achieve DRY-ness in tests. The usage of karate.write() here is just an example, you can use JS or Java interop as needed. Normally an undefined variable results in nasty JavaScript errors. The business of web-services testing requires access to low-level aspects such as HTTP headers, URL-paths, query-parameters, complex JSON or XML payloads and response-codes. scriptAll() can take a third argument which has to be a JavaScript predicate function, that returns a boolean true or false. After that We will automate APIs of GitHub Repo V3. In rare cases, e.g. JSON can be combined with the ability to call other *.feature files to achieve dynamic data-driven testing in Karate. This does require you to move set-up into a separate *.feature (or JavaScript) file. If you have trouble with
