How does Karate Framework work?

Karate Framework is built on top of the Cucumber JVM framework, which uses the Gherkin language (Given, When, Then) to write tests. Therefore, Karate presents its syntax following the Gherkin statements that make tests very readable, even by non-technical members.

Karate also makes API testing easy by providing a lot of useful features. For instance, it provides built-in support for HTTP requests, JSON & XML payloads, and wiremocks. Karate also makes use of embedded JavaScript to easily test non-functional requirements like performance and security.

How to get started with Karate Framework?

If you want to start using Karate Framework, you will require Java 8 or later on your system. First, download the `karate.jar` file, which contains the runtime library.

After downloading the `karate.jar`, it’s time to get started. Create a `.feature` file and start writing the tests. The test suites are automatically interpreted from these `.feature` files containing `Scenario` and `Background` blocks.

Karate requires test data to be coded in JSON, so you have to convert other file formats to JSON for use with Karate. Karate has built-in support to automate data-driven tests and functions that help you configure your API endpoint.

Introduction

If you’re wondering what Karate framework is, then you’re in the right place. Karate is an open-source user interface (UI) automation testing framework that uses the Cucumber syntax for writing tests. It’s a powerful tool that allows developers to create web services and automate UI testing using a seamless script structure. Here are some of the most frequently asked questions about Karate Framework.

What sets Karate apart from other frameworks?

Karate stands out from other automation testing frameworks because it combines API testing, UI testing, and performance testing all in one framework. It streamlines the testing process and simplifies the script development by taking advantage of Gherkin syntax. Also, it eliminates the need for setting up and managing multiple tools as Karate can perform multiple testing types in a single environment.

Karate follows the RESTful approach to API testing which means that it interacts with the server by sending HTTP requests and then verifying the responses. At the same time, it also incorporates UI testing for web applications, eliminating the need for separate UI automation testing tools.

What programming languages does Karate use, and is it easy to learn?

Karate framework’s test scenarios are written in Gherkin syntax or BDD (Behavior Driven Development) style. It uses a simplified dialect of JSON for API automation testing, making it easy to read and write tests quickly. Besides, Karate has built-in support for HTTP and REST for API testing, which reduces the need for extensive coding.

The good thing about Karate framework is that you don’t have to be an expert in programming to use it. Since it uses Gherkin syntax, it’s easier to learn and write tests without much coding knowledge. Additionally, it has comprehensive documentation and user guides, which makes it easy to get started with.

Can Karate be integrated with other tools?

Yes, Karate can be easily integrated with other tools such as Maven, Gradle, Cucumber, and JUnit. Maven and Gradle provide the tooling required to build and manage Karate’s project structure. Cucumber generates the report for the test cases which makes it easy to understand and interpret the results. JUnit is used for running the tests and integrating them with your build pipeline.

What are the benefits of using Karate framework?

There are several benefits of using Karate framework, some of which are:

1. Time-saving: Karate framework saves a lot of development time as it eliminates the need for multiple tools or language proficiency. It can be used for API testing, UI testing, and performance testing, which streamlines the testing process.

2. Simplified test case design: Since Karate follows Gherkin syntax, it simplifies the test case design process. You can define test cases in plain English or any language of your choice, which makes it easier to understand and interpret the results.

3. Effective reporting: Karate has built-in support for generating reports for test cases, which includes details about the test data, HTTP requests made, and the responses received. It also includes information on the test environment, making it easier for developers to debug errors.

4. Easy integration: Karate can be easily integrated with other tools such as Cucumber, Maven, and JUnit, which makes it easier to run tests and generate reports.

What is Karate Framework and How to Use it?

Karate is an open-source testing automation framework that has gained immense popularity among developers due to its powerful features, easy-to-use syntax, and rich documentation. It is built on top of the Cucumber framework and provides a unified and expressive way to test API, web, and mobile applications using a single script.

In this article, we will explore the basics of Karate framework, how to install it, configure it, and use it to carry out testing of different types of applications.

Step 1: Installing Karate Framework

Karate can be installed on any operating system (Windows, macOS, or Linux). However, to get started, you should have the following prerequisites:

• Java Development Kit (JDK) version 8 or later
• Apache Maven build tool
• A code editor (such as Visual Studio Code, IntelliJ, or Eclipse)

To install Karate, open the command prompt or terminal and run the following command:

mvn archetype:generate -DarchetypeGroupId=com.intuit.karate -DarchetypeArtifactId=karate-archetype -DarchetypeVersion=0.8.1 -DgroupId=com.mycompany -DartifactId=myproject

This should download and install the Karate project with all the necessary dependencies and plugins. Once the installation is complete, you can open your project in your code editor and start writing tests.

Step 2: Writing Test Scenarios in Karate

Karate uses a simple, yet powerful, syntax based on Gherkin and Cucumber to write test scenarios. In Karate, a test scenario consists of the following parts:

• Background: This section defines any pre-requisite steps that are required for the test scenario.
• Scenario: This section defines the actual test scenario.
• Given, When, Then, And: These are the keywords used to define the steps in the scenario.

Here is an example of a simple test scenario in Karate:


Background:
Given url 'https://reqres.in/api/users'

Scenario: Get Users
When method get
Then status 200
And match response.data[0].first_name == 'George'


In this example, we are testing the Get method of the Reqres API to check if the API returns a 200 status code and if the first_name of the first user returned is ‚George‘.

Step 3: Running Tests in Karate

To run a test in Karate, you can simply run the following command in the terminal:

mvn test

This will run all the tests that are contained in the project. You can also run specific tests or test suites by using the following commands:

mvn test -Dtest=TestName

mvn test -Dtest=ClassName

Step 4: Reporting in Karate

Karate provides detailed reports for each test run. By default, it generates a report in HTML format that shows the status of each test case, the duration of the test run, and any errors that occurred.

You can also generate a JUnit report by adding the following code to your pom.xml file:

<plugin>
<groupId>com.github.kirakishin</groupId>
<artifactId>mvn-karate-json-report</artifactId>
<version>0.9.6</version>
<executions>
<execution>
<phase>test</phase>
<goals>
<goal>generate</goal>
</goals>
</execution>
</executions>
</plugin>

This will generate a JUnit report that can be consumed by other tools such as Jenkins or Bamboo.
