If you’re new to Karate Test Framework, here’s a step-by-step guide to help you get started.

Step by Step Guide on How to Use Karate Test Framework

Step 1: Download and Install Java SDK

In order to start using Karate, you must first download and install Java SDK. The installation wizard is very easy to use, and you don’t need any experience to install it. Go to the official Java website and download the relevant version that suits your operating system. Follow the installation instructions carefully, and you’ll be ready to move to the next step in no time.

Step 2: Install Karate Framework

The next step is to install the Karate framework. To do this, you’ll first need to download it from the Karate website. In this guide, we’ll use version 0.9.6 as an example.

After the download is complete, go to the folder where it’s saved, and unzip it. Once that’s done, you can copy the directory to your local drive. Then, you can add it to your PATH environment variable.

Step 3: Create a New Karate Project

Now it’s time to start working on your Karate project. The first thing you need to do is create a new project. To do that, create a new directory, and inside the directory, create a new file called „karate-config.js“. This file contains the configuration name for the Karate project.

Step 4: Create a Feature Test File

After creating a new project, you need to create a feature test file. This file will contain the test scenarios for your API. To create a new feature test file, create another file inside the project directory, and call it whatever name you want. In this guide, we’ll call it „example.feature“.

Step 5: Write Your First Karate Test

It is now time to write your first test case. A sample test case can be written in the file we created earlier called „example.feature“.

„`Feature: Test Karate Framework
Scenario: Check Sample GET endpoint
Given url ‚https://jsonplaceholder.typicode.com/posts‘
When method GET
Then status 200
And match response == ‚#[1]’„`

This test will send a GET request to the URL provided and check if the response status is 200. Also, it will match the response body to ensure that the returned data is valid.

Step 6: Run the Test with Command Line

After creating your first test, the next thing you need to do is to run it using the command line interface. To do this, navigate to your project directory, where the „example.feature“ file is saved. Then run the following command:

„`mvn test„`

With this command, Karate will start running the tests in „example.feature.“

Step 7: View Test Reports

After running tests using Karate Test Framework, you’ll get detailed test reports about the tests you’ve run. Karate generates comprehensive HTML reports that make it easy to see the results of your tests. You can view run reports by loading the „target/surefire-reports/index.html“ file in your browser. You should see something like this:

„`[INFO] ————————————————————————
[INFO] BUILD SUCCESS
[INFO] ————————————————————————
[INFO] Total time: 01:03 min
[INFO] Finished at: 2021-09-15T15:25:33+05:30
[INFO] ————————————————————————
„`
