How to Create a Karate Project in IntelliJ
Karate is an open-source testing framework inspired by the Cucumber and Gherkin syntax, providing an easy and expressive way to test web services. IntelliJ is a widely used integrated development environment for writing and debugging code across various programming languages. Combining these two tools can help you create robust and efficient tests for your web services. In this blog post, we will walk you through the steps on how to create a Karate project in IntelliJ.
Prerequisites
Before we start creating a Karate project in IntelliJ, there are a few prerequisites that need to be met:
- Java Development Kit (JDK) – Check if the JDK is already installed on your machine by running the command ‚java -version‘ in the terminal or command prompt. If not, install the latest version of JDK from the Oracle website.
- IntelliJ – Download and install the latest version of IntelliJ from the JetBrains website.
- Karate JAR file – Download the latest Karate JAR file from the Maven Central Repository or the GitHub Releases page.
Step 1: Create a New Project
Open IntelliJ and click on ‚File‘ -> ‚New‘ -> ‚Project‘. In the ‚New Project‘ dialog box, select ‚Maven‘ under ‚Project SDK‘ and click on ‚Next‘.
In the next dialog box, enter the following details:
- ‚GroupId‘: Enter a unique identifier for your project.
- ‚ArtifactId‘: Enter a unique name for your project.
- ‚Version‘: Enter the initial version of your project.
- ‚Project name‘: Enter a name for your project.
Keep all other options as default and click on ‚Finish‘. IntelliJ will create a new Maven project with the specified details.
Step 2: Add Karate Dependency
Once the project is created, open the ‚pom.xml‘ file located in the root directory of your project.
Add the following dependency to the ‚pom.xml‘ file:
„`
„`
This dependency includes the Karate JUnit 5 runner that enables you to run your Karate tests in IntelliJ.
Step 3: Create a Karate Test File
Create a new directory named ’src/test/java‘ in the root directory of your project. Inside this directory, create a new Java class file and name it ‚KarateTest.java‘.
In this file, add the following code:
„`
import com.intuit.karate.junit5.Karate;
class KarateTest {
@Karate.Test
Karate testSample() {
return Karate.run(„sample“).relativeTo(getClass());
}
}
„`
This code creates a Karate test that runs the ’sample.feature‘ file relative to the current class location.
Step 4: Create a Karate Feature File
Create a new directory named ’src/test/resources‘ in the root directory of your project. Inside this directory, create a new file named ’sample.feature‘. This file will contain the Karate scenarios that we want to test.
Add the following code to the ’sample.feature‘ file:
„`
Feature: Sample Feature
Scenario: Sample Scenario
Given url ‚https://reqres.in/api/users/2‘
When method get
Then status 200
„`
This code defines a simple Karate scenario that sends a GET request to the ReqRes API and verifies that the response status is 200.
Step 5: Run the Karate Test
To run the Karate test in IntelliJ, right-click on the ‚KarateTest.java‘ file and select ‚Run KarateTest‘.
IntelliJ will start the Karate JUnit test runner and run the specified Karate test. The Karate test results will be displayed in the IntelliJ console.
