} 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 ! To run a script *.feature file from your Java IDE, you just need the following empty test-class in the same package. Although rarely needed, variable references or expressions are also supported: This is a shortcut to assert the HTTP response code. Note: desiredCapabilities has been deprecated and not recommended for use. Note that the optional(), exists() and locate() APIs are a little different from the other Element actions, because they will not honor any intent to retry() and immediately check the HTML for the given locator. for simulating check-boxes and multi-selects): You can also dynamically set multiple fields in one step using the form fields keyword. You can see how it can be re-used anywhere to scrape the contents out of any HTML tabular data, and all you need to do is supply the locator that matches the elements you are interested in. 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. Since paths are expected at the end of the command-line options - if you want to only over-ride tags, use the = sign to make argument values clear. There is no need to escape characters like you would have had to in Java or other programming languages. Navigates to a new page / address. If the machine where you are running Karate is not the same as your target host (e.g. First the JavaScript file, basic-auth.js: And heres how it works in a test-script using the header keyword. You can even mix this into mouse() actions. Karate has the following short-cut symbols designed to be mixed into embedded expressions: For completeness, == and != also belong in the above list. Karate Framework is an open-source Behavior Driven Development (BDD) testing framework for API test automation, performance testing, and UI testing. Bloating your configuration can lead to loss of performance, and maintainability may suffer. """, # normal 'equality' match. The variable state after feature execution would be returned as a Map. And steps that follow should logically be in the Then form. 1. . For example, here below is an actual report generated by the cucumber-reporting open-source library. By now, it should be clear that JsonPath can be very useful for extracting JSON trees out of a given object. In the above example, the end-result of the call to my-signin.feature resulted in the authToken variable being initialized. """, Then match each response contains deep { a, # should be an array of strings with size 2, # each array element should have a 'length' property with value 3, # should be an array of strings each of length 3, """ "arr": [ 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. We configure cors = true to ensure that the browser does not complain about cross-origin requests. If you read from a file, the advantage is that multiple scripts can re-use the same data. c Karate is the only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. What started as a powerful, scriptable framework combining API and UI test automation, is adopted as a best-practice today - in teams around the world. This will wait until the element (by locator) is present in the page and uses the configured retry() settings. This behavior where all key-value pairs in the returned map-like object get automatically added as variables - applies to the calling of *.feature files as well. 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". Passing the data from one feature file to another file. Karate is the open source tool to combine API test automation, mockery, performance testing and even UI automation into a single framework. """, //DEPS com.intuit.karate:karate-core:RELEASE:all, "https://jsonplaceholder.typicode.com/users", * def expected = __num == 0 ? This capability is triggered when the table consists of a single cell, i.e. Here is an example of an implementation. One limitation is that you cannot use double-quotes within these expressions, so stick to the pattern seen below. And yes, you can use variable expressions from karate-config.js. Listed on 2023-03-01. Or - if a call is made without an assignment, and if the function returns a map-like object, it will add each key-value pair returned as a new variable into the execution context. Karate is an external domain-specific language based on Gherkin language to create API, Web UI, and Desktop UI tests. To use the recommended --security-opt seccomp=chrome.json Docker option, add a secComp property to the driverTarget configuration. Refer to the section on dynamic port numbers for an example. 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. """, """ With the above in place, you dont have to keep switching between your src/test/java and src/test/resources folders, you can have all your test-code and artifacts under src/test/java and everything will work as expected. // trigger download of latest image with custom file name """, # 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. This roughly corresponds to a cURL argument of -F @myFile=test.pdf. Only one JSON argument is allowed, but this does not limit you in any way as you can use any complex JSON structure. Refer to conditional logic for more ideas. Assertions and HTML reports are built-in, and you can run tests in parallel for speed. Refer to the documentation for cookie for details and how you can disable this if need be. Empty cells or expressions that evaluate to null will result in the key being omitted from the JSON. Karate has a built-in implementation for Docker (DockerTarget) that supports 2 existing Docker images out of the box: To use either of the above, you do this in a Karate test: Or for more flexibility, you could do this in karate-config.js and perform conditional logic based on karate.env. Karate Labs is an industry leading open-source test automation solution unifying API & UI test automation. Multiple fields can be set in one step using multipart fields. name: John Karate supports JUnit 5 and the advantage is that you can have multiple methods in a test-class. 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. Here below is an example jbang script that uses the Karate Java API to do some useful work. So especially when doing above() or below(), ensure that the search path is aligned the way you expect. if you want to conditionally stop a test with a descriptive error message, e.g. It may be easier for you to use the Karate Maven archetype to create a skeleton project with one command. Here is how to replace one placeholder at a time: Karate makes it really easy to substitute multiple placeholders in a single, readable step as follows: Note how strings have to be enclosed in quotes. JsonPath and Karate expressions are not supported. For example you can get a nice feature coverage report, provided you have a rich set of tags. Since it is so easy to dive into Java-interop, Karate does not include any random-number functions, uuid generator or date / time utilities out of the box. Example: Get the HTML element attribute value by attribute name. odds: '#[] oddSchema' The Maven tradition is to have non-Java source files in a separate src/test/resources folder structure - but we recommend that you keep them side-by-side with your *.java files. You can easily assign the whole response (or just parts of it using Json-Path or XPath) to a variable, and use it in later steps. The above logic can actually be replaced with Karates built-in short-cut - which is waitForResultCount() Also see waits. But note that you can use the negative form of a tag selector: ~@region=GB. Here is an example of using a CSV file as the request-body: Karate provides a flexible way to compare two images to determine if they are the same or similar. Pay attention to the fact that the includes() function you see in the above example - is pure JavaScript. The example below shows the difference between embedded expressions and enclosed JavaScript: So how would you choose between the two approaches to create JSON ? 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. } [{ Note that the opposite of optional() is locate() which will fail if the element is not present. This also works as a getter to get the current window dimensions. Karate will traverse sub-directories and look for *.feature files. Of course this can be useful if the element you are seeking is diagonally offset from the locator you have. The syntax is easy to understand by non-programmers. You can call send() on the returned object to send a message. name,type """, """ JavaScript functions have some limitations when combined with multi-threaded Java code. JSON / arrays), see, executes an OS command, but forks a process in parallel and will not block the test like, for advanced conditional logic for e.g. 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. In the feature below, the * print 'in setup' step will run only once. # reset to defaults for the rest of the test //www.seleniumeasy.com/test/dynamic-data-loading-demo.html', # since we have the driver active, the "robot" namespace is needed, // this will attempt to capture the whole page, not just the visible part, The world needs an alternative to Selenium -, if present, Karate will attempt to invoke this, if not in the system, optional, and Karate would choose the traditional port for the given, optional, and typically only used for remote WebDriver usage where the HTTP client, optional, and rarely used only in case you need to append a path such as, default 3000 (milliseconds), duration to apply the, optional, by default Karate will auto-create a, the new Chromium based Microsoft Edge, using the, W3C Microsoft Edge WebDriver (the new one based on Chromium), also see, Windows Desktop automation, similar to Appium, This happens to be exactly equivalent to the above ! 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. You can always directly access the variable called responseHeaders if you wanted to do more checks, but you typically wont need to. For a call (or callonce) - payload / data structures (JSON, XML, Map-like or List-like) variables are passed by reference which means that steps within the called feature can update or mutate them, for e.g. 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. function(x, y, i) { The documentation on how to run tests via the command line has an example of how to use tags to decide which tests to not run (or ignore). Step 3: Add steps to run a sample POST API request. If you are looking for a way to do something only once per Feature, take a look at callonce. 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. 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. You can even chain a submit() to wait for a page load if needed: Since moving the mouse is a common task, these short-cuts can be used: These are useful in situations where the normal click() does not work - especially when the element you are clicking is not a normal hyperlink () or
