Karate and BDD Karate is built on top of Cucumber, another BDD testing framework, and shares some of the same concepts. For an example, refer: upload-multiple-files.feature. Since replace auto-converts the result to a string, make sure you perform type conversion back to JSON (or XML) if applicable. This means that you can combine them to concisely express certain types of intent - without having to repeat the locator. (not) operator is especially useful for contains and JSON arrays. Standard JavaScript syntax rules apply, but the right-hand-side should begin with the function keyword if declared in-line. 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. Behaves the same way as the. Also look at the demo examples, especially dynamic-params.feature - to compare the above approach with how the Cucumber Scenario Outline: can be alternatively used for data-driven tests. In rare cases, you may want to check what the type of the response is and it can be one of 3 different values: json, xml and string. You can over-ride it by using the header keyword before the method step. To avoid problems, stick to the pattern of using double-quotes to wrap the JavaScript snippet, and you can use single-quotes within. Note how we read as a string, but cast to JSON: If you want to use the triple-quote / multi-line way of defining JSON or if you have to use XML - you can use text and cast to JSON or XML as a second step - before using in a match: Karates match is strict, and the case where a JSON key exists but has a null value (#null) is considered different from the case where the key is not present at all (#notpresent) in the payload. Of course, resorting to a sleep in a UI test is considered a very bad-practice and you should always use retry() instead. Automation Testing, Karate. Best-practice would be to implement Hybrid Tests where the values for the auth-cookies are set only once for the whole test-suite using karate.callSingle(). So in dev mode you can easily set this behavior like this. multipart file. And you dont need to create additional Java classes for any of the payloads that you need to work with. Note that regex escaping has to be done with a double back-slash - for e.g: '#regex a\\.dot' will match 'a.dot'. It will create a Karate report under Karate Project > target > Karate report > karate-summary.html, Step 4: Create a TestRunner.java class under src/test/java. Step 3: Create a feature file and write a Scenario. This can loop until any user-defined condition and can use any variable (or Karate or Driver JS API) in scope. 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. Karate has an elegant approach to handling any action such as click() that results in a new page load. You can use karate.callSingle() in karate-config.js like this: It can take a second JSON argument following the same rules as call. So even if your next step is the ENTER key, you can do this: Karate will do the best it can to detect a page change and wait for the load to complete before proceeding to any step that follows. The contents of my-signin.feature are shown below. But this totally makes sense for things not part of the main test flow and which typically need to be re-usable anyway. Also see type conversion. The method argument is JSON, so that you can pass more data in addition to the value such as domain and url. Note that more builder methods are available from the Runner.Builder class such as reportDir() etc. Billie,LOL Some third-party report-server solutions integrate with Karate such as ReportPortal.io. { Imagine a situation where you want to get only the element where a certain attribute value starts with some text - and then click on it. }". You can also dynamically set multiple files in one step using multipart files. But you can choose a single test to run like this: When your Java test runner is linked to multiple feature files, which will be the case when you use the recommended parallel runner, you can narrow down your scope to a single feature, scenario or directory via the command-line, useful in dev-mode. ", Karate will wrap the function for you ! When the level is DEBUG the entire request and response payloads are logged. '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. Just ensure that this is configured before you use karate.callSingle(): By default Karate will use target (or build) as the cache folder, which you can over-ride by adding a dir key: This caching behavior will work only if the result of karate.callSingle() is a JSON-like object, and any JS functions or Java objects mixed in will be lost. } // trigger download of latest image with custom file name Also referred to as mutual auth - if your API requires that clients present an X509 certificate for authentication, Karate supports this via JSON as the configure ssl value. You can experiment by using XPath snippets like the span/a seen above for even more narrowing down, but try to expand the scope modifier (the part within curly braces) only when you need to do de-duping in case the same user-facing text appears multiple times on a page. And the start() method will be invoked as soon as any Scenario requests for a web-browser instance (for the first time) via the driver keyword. As a short-cut, when running JsonPath expressions - $ represents the response. 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. { id: 42, name: 'Wild' } And especially when it comes to test-automation, we have found that attempts to apply patterns in the pursuit of code re-use, more often than not - results in hard-to-maintain code, and severely impacts readability. This video explain how to do UI Automation using Karate DSL.If you like this video please do subscribe to my channel and keep watching ! 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. This means that all your. In cases where the data-source needs multiple steps, for e.g. Since Karate combines API testing capabilities, you can sign-in to your SSO store via a REST end-point, and then drop cookies onto the browser so that you can bypass the user log-in experience. name: John Do look at the documentation and example for configure headers also as it goes hand-in-hand with call. the NOT operator e.g. You can change the com.intuit.karate logger level to INFO to reduce the amount of logging. You should be able to right-click and run a single method using your IDE - which should be sufficient when you are in development mode. The configure driver options are fine for testing on localhost and when not in headless mode. So it is recommended that you directly use a Java Function when possible instead of using the karate.toJava() wrapper as shown above. Multiple fields can be set in one step using multipart fields. 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. Look at how the path did not need to be specified for the second HTTP get call since /cats is part of the url. ] The not equals operator != works as you would expect: You typically will never need to use the != (not-equals) operator ! In some rare cases you need to exit a Scenario based on some condition. But if you really need to use the HTTP response code in an expression or save it for later, you can get it as an integer: Note that match can give you some extra readable options: The response time (in milliseconds) for the current response would be available in a variable called responseTime. We even slip in a page-URL assertion without missing a beat. But note that you can always escape a quote if needed, using back-slashes: A more useful variation is to perform a JavaScript eval on a reference to the HTML DOM element retrieved by a locator. """, # yaml from a file (the extension matters), and the data-type of 'bar' would be JSON, """ Karate uses LOGBack which looks for a file called logback-test.xml on the classpath. You can organize multiple common utilities into a single re-usable feature file as follows e.g. If you have to set a bunch of deeply nested keys, you can move the parent path to the top, next to the set keyword and save a lot of typing ! Karate UI automation, is it possible to make locators dynamic. """, """ The default is 30000 (30 seconds). And this call is using shared scope. Note how we can even serve an image with the right Content-Type header. Also make sure that you complete the set up of things like url, param, header, configure etc. This means that as long as the token on file is valid, you can save time by not having to make the one or two HTTP calls needed to sign-in or create throw-away users in your SSO store. During variable creation, the gherkin keyword is optional. When handling XML, you sometimes need to call XPath functions, for example to get the count of a node-set. IMPORTANT: There are some restrictions when using callonce or karate.callSingle() especially within karate-config.js. And if you use the following mock, it will actually act as a pass-through proxy - but with the advantage that every single request and response will be emitted to target/karate.log. Here is an example of what is possible: Not something you would commonly use, but in some cases you need to disable Karates default behavior of attempting to parse anything that looks like JSON (or XML) when using multi-line / string expressions. They are param, header, cookie, form field and multipart field. odds: '#[] oddSchema' I have used this for my response. A Java API also exists for those who prefer to programmatically integrate Karates rich automation and data-assertion capabilities. path to file containing public and private keys for your client certificate. } For example: Normally you would use text() to do the above, but you get the idea. Of course this can be useful if the element you are seeking is diagonally offset from the locator you have. The default is: * configure driver = { headless: false }. This is typically combined with multipart file as shown below. Experience working in an Agile environment with agile methodologies leveraging Jira Note that you typically would set start: false as well, or use a Custom Target. Here is the same example using this approach, where a couple of images need to be saved as part of the test-script: A video of the above execution can be viewed here. Karate will also run Scenario-s in parallel by default. } function (customConfigJson, config) { Expressions are evaluated using the embedded JavaScript engine. This is very useful to filter the results that match a desired condition - typically a text comparison. If Chrome is not installed in the default location, you can pass a String argument like this: For more control or custom options, the start() method takes a Map argument where the following keys (all optional) are supported: Only supported for driver type chrome. See below screenshot I have created new put feature file and written Put method for updating employee name. Karate is an open-source tool which combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. 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. It is worth taking a few minutes to go through the documentation and examples here: JsonPath Examples. You can do this. In fact, this is the mechanism used when karate-config.js is processed on start-up. Read the documentation of the stand-alone JAR for more - such as how you can even install custom command-line applications using jbang ! }, Note that if you need to do a lot of case-insensitive string checks, karate.lowerCase() is what you are looking for. 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. Although rarely needed, variable references or expressions are also supported: This is a shortcut to assert the HTTP response code. Another example for a popular Maven reporting plugin that is compatible with Karate JSON is Cluecumber. You can still perform string comparisons such as a match contains and look for error messages etc. 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. For an example of how JavaScript looks like on the Karate side see Function Composition. There are multiple Karate API testing examples we are going to show you in this series. 5678 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. Note that the Java class does not need to be public and even the test methods do not need to be public - so tests end up being very concise. So you can do things like this: * def name = name + __loop - or you can use the loop index value for looking up other values that may be in scope - in a data-driven style. You can see a demo video here. Instead you would typically use the match keyword, that is designed for performing powerful assertions against JSON and XML response payloads. For example: And similarly for XML and XPath, / represents the response. And thats all there is to Karate configuration ! If you use commas (instead of concatenating strings using +), Karate will pretty-print variables, which is what you typically want when dealing with JSON or XML. 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). Observe how you can match the result of a JsonPath expression with your expected data. The .graphql and .gql extensions are also recognized (for GraphQL) but are handled the same way as .txt and treated as a string. The BDD syntax that Cucumber has gone on to popularize is language-neutral, which makes it easy for nonprogrammers as well. There may be cases where you want to suppress this to make the reports lighter and easier to read. Karate an Open source framework developed by Karatelabs has made Test Automation simple and unified for both API testing and UI Automation using Gherkins. If you need to actually do something with each returned Element, see locateAll() or the option below. If a handler function (returning a boolean) is provided - it will be used to complete the listen wait if true is returned. Here is the above example re-written to do so: The result of karate.setup() will be a JSON of all the variables created within the Scenario tagged with @setup. You can do this by multiplying by 1 or using the built-in JavaScript parseInt() function: As per the JSON spec, all numeric values are treated as doubles, so for integers - it really doesnt matter if there is a decimal point or not. Notice that in the above example, string values within the table need to be enclosed in quotes. "b": 4, If you mix Karate into a Maven or Gradle project with many other dependendies, you may run into problems because of dependency conflicts. You may face issues if you attempt to mix in JS functions or Java code. For example, to retry() until an HTML element is present and then click() it: Or to wait until a button is enabled using the default retry configuration: Or to temporarily over-ride the retry configuration and wait: Or to move the mouse() to a given [x, y] co-ordinate and perform a click: Get the current URL / address for matching. Navigates to a new page / address. Karate Framework is an open-source Behavior Driven Development (BDD) testing framework for API test automation, performance testing, and UI testing. The special predicate marker #? 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. Step 3: Provide the project details and create project, Step 4: Add Maven dependencies in pom.xml. "c": 3 When using Playwright you can omit this in which case Karate will default to Chrome (within Playwright) and the default browser window size. Note that it uses a string contains match, so you just need to supply a portion of the URL you are expecting. Being able to define and re-use JavaScript functions is a powerful capability of Karate. Note that for. {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", """ } There is also a variant of Scenario called Scenario Outline along with Examples, useful for data-driven tests. For JSON, you can also use the JS delete operator via eval, useful when the path you are trying to mutate is dynamic. var results = scriptAll('.js-tree-browser-result-path', '_.innerText'); This is more compact, and is especially useful for expressions that do not start with the current DOM element. Here is an example: binary.feature. Theres a lot going on in the last line above ! Heres a simple recipe to set up this mechanism on your local machine. You cant do things such as * url 'http://foo.bar' and expect the URL to be set in the called feature. entityState: "ACTIVE" Since Karate uses Gherkin, you can also employ data-driven techniques such as expressing data-tables in test scripts. "arr": [ And since you can easily extend Karate using JavaScript, there is no need to compile Java code any more. Instead of using call (or callonce) you are always free to call JavaScript functions normally and then you can use more than one argument. The Karate regression test-suite that runs in GitHub actions (effectively our CI) - includes another example, and you can find a good explanation here. String interpolation will support variables in scope and / or the Examples (including functions defined globally, but not functions defined in the background). The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. 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. Observe how using JSON for parameter-passing makes things super-readable. 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. Since asserting against header values in the response is a common task - match header has a special meaning. It is best explained via examples. As a convenience, cookies from the previous response are collected and passed as-is as part of the next HTTP request. Based on the above details, you should be able to come up with a custom strategy to connect Karate to Playwright. The karate-demo has an example showing various ways to configure or set headers: headers.feature. { In below image we can see I have created feature file. Here are the configuration keys supported: If you need to set any of these globally you can easily do so using the karate object in karate-config.js - for e.g: In rare cases where you need to add nested non-JSON data to the configure value, you have to play by the rules that apply within karate-config.js. It is one of the great tool for API testing. = . To make dynamic data-driven testing easier, the following keywords also exist: params, headers, cookies and form fields. The assert keyword can be used to assert that an expression returns a boolean value. """, # use dynamic path expressions to mutate json, * def filename = zone == 'zone1' ? !contains deep is not yet supported, please contribute code if you can. Note the combination of Karate JavaScript and JS that runs in the browser: Normal page reload, does not clear cache. 2 Billie The responseCookies variable is set upon any HTTP response and is a map-like (or JSON-like) object. { As a convenience you can use the Chrome concrete implementation of a Driver directly, designed for common needs such as converting HTML to PDF - or taking a screenshot of a page. This can be convenient if a particular call results in a huge response payload. With the formalities out of the way, lets dive straight into the syntax. 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. You can selectively re-direct some HTTP requests that the browser makes - into a Karate test-double ! For example here is the equivalent of the example above. 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. Karate makes re-use of payload data, utility-functions and even other test-scripts as easy as possible. This means: Where login.feature would look something like: There are many ways to parameterize the driver config or perform environment-switching, read this for more details. You can add (or over-ride) variables by passing a call argument as shown above. The keywords Given When Then are only for decoration and should not be thought of as similar to an if - then - else statement. 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. Note that the duration is in milliseconds. } This is just a convenience short-cut for waitUntil(locator, "_.textContent.includes('" + expected + "')") since it is so frequently needed. Note that the opposite of optional() is locate() which will fail if the element is not present. Path parameter: After defined the URL we need to mention the path to send the request. The keywords def, set, match, request and eval take multi-line input as the last argument. return a pretty-printed, nicely indented string representation of the JSON value, also see: return a pretty-printed, nicely indented string representation of the XML value, also see: get the value of any Java system-property by name, useful for, returns a JSON array of integers (inclusive), the optional third argument must be a positive integer and defaults to 1, and if start < end the order of values is reversed, very rarely used - when needing to perform conditional removal of JSON keys or XML nodes. ) testing framework for API testing and UI automation using Gherkins the Content-Type.
