karate framework for ui automation

And steps that follow should logically be in the Then form. """, # very useful for validating a response against a schema "super-set", * match karate.filterKeys(response, 'b', 'c') == { c, * match karate.filterKeys(response, ['a', 'b']) == { a, # generate a range of numbers as a json array, """ 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. It will be initialized only after the driver keyword has been used to navigate to a web-page (or application). Behind the scenes, this sets the HTTP communication read timeout. squares.push(foo(n)); We can use this with param in And condition like below. This also works as a getter to get the current window dimensions. 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. So we use the same Gherkin syntax - but the similarity ends there. Karate Framework Test Automation Made Simple. Sending GET, POST, PUT, PATCH and DELETE requests via Karate framework 3. 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. As a rule of thumb, prefer match over assert, because match failure messages are more detailed and descriptive. When you are in a hurry, you can pause a test in the middle of a flow just to look at the browser developer tools to see what CSS selectors you need to use. And any variables which are alive in the context can be used in this expression. This can be achieved using karate.callSingle(). 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. And similarly - for specifying the HTTP proxy. In other words, when call or callonce is used without a def, the called script not only shares all variables (and configure settings) but can update the shared execution context. This is like the opposite of set if you need to remove keys or data elements from JSON or XML instances. If you are familiar with Cucumber / Gherkin, the big difference here is that you dont need to write extra glue code or Java step definitions ! 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. """, """ 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. Example: In an application testing if we are login the application in each scenario then we can put the login scenario under background. Instantiating a Java class and using this in a test is easy (see example): Since karate-config.js is processed for every Scenario, you can use a singleton instead of calling new every time. They should be at the end of the karate.options. 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. Note that def will over-write any variable that was using the same name earlier. If you want to dynamically and programmatically determine the tags and features to be included - the API also accepts. Karate is an open-source API (SOAP & REST) testing automation tool written in Java. Normally in dev mode, you will use your IDE to run a *.feature file directly or via the companion runner JUnit Java class. If you really want a long-running flow that combines steps from multiple features, you can make a call to each of them from the single top-level Scenario. The example below combines this with the advanced features described above. But you will never need to worry about this internal data-representation most of the time. This is best explained with an example. Also refer to this demo example for a working example of multipart file uploads: upload.feature. 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. For advanced examples, refer to some of the scenarios within this demo: dynamic-params.feature. It may be easier for you to use the Karate Maven archetype to create a skeleton project with one command. Here is an example: Any Karate variable will be available to the template, which is users.html in this example. return results.size() == 2 ? This is especially relevant when manipulating GraphQL queries - because although they look suspiciously like JSON, they are not, and tend to confuse Karates internals. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. var results = innerText('.js-tree-browser-result-path'); And each element of the returned array will be the envelope of variables that resulted from each iteration where the *.feature got invoked. The first argument to karate.callSingle() is used as the cache key. 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. Features API and UI automation Conditional logic is not recommended especially within test scripts because tests should be deterministic. To make dynamic data-driven testing easier, the following keywords also exist: params, headers, cookies and form fields. The Karate project team is of the opinion that things can be made simpler. It is sometimes useful to be able to check if a key-value-pair does not exist. For JUnit 5 you can omit the public modifier for the class and method, and there are some changes to import package names. You can even perform a conversion from XML to JSON if you want. """, """ This is convenient for complex nested payloads where you are sure that you only want to check for some values in the various trees of data. 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. This should make it clear why Karate does not provide out of the box support for any particular HTTP authentication scheme. 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. 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). And yes, functions can take arguments. Use the classpath: prefix to load from the classpath instead. return sdf.parse(s).time; // '.getTime()' would also have worked instead of '.time' A working example of calling a SOAP service can be found within the Karate project test-suite. For an example, refer: upload-multiple-files.feature. 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. Note that the set (multiple) keyword can build complex, nested JSON (or XML) from scratch in a data-driven manner, and you may not even need to read from files for many situations. Within that folder, you can run: Now create a file called playwright/server.js with the following code: The main thing here is that the server URL should be logged to the console when it starts. So you can compare 2 JSON (or XML) payloads if you wanted to: If you are wondering about the finer details of the match syntax, the Left-Hand-Side has to be either a. You should be able to run tests in parallel with ease ! See karate.callSingle(). There are two types of code that can be call-ed. The default is 30000 (30 seconds). path to file containing public and private keys for your client certificate. # but using karate.range() you can even do this ! It is best explained via examples. Step 3: Provide the project details and create project, Step 4: Add Maven dependencies in pom.xml. The demo also features code-coverage using Jacoco, and some tips for even non-Java back-ends. A special case of embedded expressions can remove a JSON key (or XML element / attribute) if the expression evaluates to null. You can ask for an element by its relative position to another element which is visible - such as a ,
