Merging Karma Test Results from Two Angular Projects: A Comprehensive Guide

Running tests in Angular applications is crucial for ensuring code quality and reliability. However, when dealing with multiple related projects, it can be challenging to combine and manage test results. This guide will help you understand how to merge Karma test results from a main Angular project and its shared module effectively, preventing data overwrites and ensuring consistent reporting.

The Problem: Overwriting Test Results

When you run tests for your main Angular project, you may encounter a situation where the test results from your shared module (which is a BitBucket submodule) overwrite each other. This leads to lost information about the tests that were performed in both projects.

Your existing setup leads to confusion about how the second project's results are being output, which ultimately results in overwritten content. To solve this issue, we need to establish a clear methodology for merging results from both projects without loss.

The Solution:Using Centralized and Extended Configuration Files

You can tackle this problem by utilizing a main karma.conf.js file that centralizes the configuration settings, complemented by project-specific configuration files that extend this main file. Below, we will break this down into manageable steps.

Step 1: Create a Main karma.conf.js

This configuration file will include the necessary settings common across both projects. Here’s an example:

Step 2: Create Project-Specific karma.conf.js

Next, create specific configuration files for each of the projects, extending the main configuration to direct output results correctly and avoid overwriting. Here’s how it can be implemented for a specific project:

Step 3: Maintain Clear Output Paths

To prevent the results from being overwritten, make sure to specify different output directories for each project's coverage reports in the coverageIstanbulReporter section of each project-specific configuration file. This ensures clarity and correctness in your reporting.

Adding TypeScript Configuration

Don’t forget about your TypeScript configuration file, tsconfig.spec.json, as it determines which test files are included during the testing process. Make sure it includes the necessary specs from both projects effectively.

Conclusion

By following this approach, you can successfully merge Karma test results from your two Angular projects without overwriting data. Utilizing a centralized configuration and extending it for specific project needs not only helps maintain clarity in results but also enhances the flexibility of your testing setup.

Feel free to adapt this structure to suit your specific requirements, and happy testing!
