Karate.Runner Execution with Multiple Tags and Features: A Comprehensive Guide

Karate is an open-source test automation framework that allows you to execute tests in parallel using the Karate.Runner class. In this article, we will delve into the karate.runner execution with multiple tags and features, providing you with clear and direct instructions on how to utilize this powerful tool.

Understanding Karate.Runner

Karate.Runner is a Java-based class that enables you to run Karate tests in parallel. It provides a flexible way to execute tests using various tags, folders, and features. With Karate.Runner, you can scale your test execution and reduce the overall testing time.

Benefits of Using Karate.Runner

• Execute tests in parallel, reducing testing time
• Run tests with multiple tags and features
• Flexibility to configure test execution
• Easy integration with CI/CD pipelines

Setting Up Karate.Runner

To use Karate.Runner, you need to have Karate installed on your system. If you haven’t installed Karate yet, follow these steps:

1. Download the Karate zip file from the official website
2. Extract the zip file to a directory on your system
3. Add the Karate bin directory to your system’s PATH environment variable

Once you have Karate installed, you can create a Java class to execute Karate tests using Karate.Runner.

import com.intuit.karate.Runner;
import com.intuit.karate.Results;

public class KarateRunner {
  public static void main(String[] args) {
    Results results = Runner.path("classpath:features").tags("~@ignore").parallel(5);
    results.getReport().generateReports();
  }
}

Executing Tests with Multiple Tags

Karate.Runner allows you to execute tests with multiple tags. Tags are used to categorize tests based on specific criteria such as functional areas, components, or environments. You can use the `tags` method to specify one or more tags to execute.

Results results = Runner.path("classpath:features").tags("@smoke, @ regression").parallel(5);

In the above example, the `tags` method specifies two tags: `@smoke` and `@regression`. Only tests with either of these tags will be executed.

Excluding Tests with Tags

You can also use the `tags` method to exclude tests with specific tags. To do this, prefix the tag with a tilde (~) character.

Results results = Runner.path("classpath:features").tags("~@ignore, ~@ ui").parallel(5);

In the above example, the `tags` method specifies two tags: `~@ignore` and `~@ui`. Tests with either of these tags will be excluded from execution.

Executing Tests with Features

Karate.Runner allows you to execute tests with specific features. Features are used to group related tests together. You can use the `feature` method to specify one or more features to execute.

Results results = Runner.path("classpath:features").feature("login.feature, payment.feature").parallel(5);

In the above example, the `feature` method specifies two features: `login.feature` and `payment.feature`. Only tests within these features will be executed.

Configuring KarateRunner

Karate.Runner provides various configuration options to customize test execution. You can use the `config` method to specify configuration options.

Runner.Options options = new Runner.Options();
options.config("karate.config", "src/test/resources/karate-config.js");

Results results = Runner.path("classpath:features").tags("@smoke").config(options).parallel(5);

In the above example, the `config` method specifies a configuration file `karate-config.js` located in the `src/test/resources` directory.

Integrating with CI/CD Pipelines

Karate.Runner can be easily integrated with CI/CD pipelines, allowing you to automate test execution as part of your continuous integration and delivery process.

CI/CD Tool	Integration Example
Jenkins	stage('Test') { steps { sh 'java -cp target/test-classes:target/dependency/* com.intuit.karate.Runner' } }
GitLab CI/CD	test: stage: test script: - java -cp target/test-classes:target/dependency/* com.intuit.karate.Runner

In the above examples, the Karate.Runner is executed as part of the CI/CD pipeline, allowing you to automate test execution and report generation.
