A tool to run Angular tests in parallel
npm install angular-parallel-test-runnerangular-parallel-test-runner is a command-line tool designed to run Angular tests in parallel across multiple projects. It utilizes the concurrency capabilities of your machine, maximizing the efficiency of running tests by leveraging multiple CPU cores.

To install angular-parallel-test-runner, use npm:
``bash`
npm install -g angular-parallel-test-runner
Make sure to have concurrently installed as a dependency if not already:
`bash`
npm install concurrently
To run tests across all Angular projects defined in your angular.json file:
`bash`
angular-parallel-test-runner [options]
| Option | Alias | Type | Default | Description |
| --------------------- | ----- | ------- | --------------------------- | -------------------------------------------------------------------- |
| --concurrency | -c | number | Half of available CPU cores | Number of concurrent test runners |--continueOnFailure
| | -f | boolean | true | Whether to continue if a test fails |--onlyProjects
| | -o | string | | Comma-separated list of projects to test (only these will be tested) |--skipProjects
| | -s | string | | Comma-separated list of projects to skip from testing |--help
| | | boolean | | Show help and usage instructions |
1. Run with default settings:
`bash`
angular-parallel-test-runner
2. Run with custom concurrency and allow all tests to finish even if some fail:
`bash`
angular-parallel-test-runner --concurrency=4 --continueOnFailure=true
3. Run and stop at the first failed test:
`bash`
angular-parallel-test-runner --continueOnFailure=false
4. Run tests only for specific projects:
`bash`
angular-parallel-test-runner --onlyProjects=project1,project2
5. Skip specific projects:
`bash`
angular-parallel-test-runner --skipProjects=project3,project4
1. Loading Angular Projects: The tool reads the angular.json file in your current directory to determine the list of projects.concurrently
2. Concurrency Management: It determines the optimal concurrency level based on your CPU cores or a user-provided value.
3. Test Execution: Uses to run tests in parallel for each project. If a project has no tests, it skips it gracefully.continueOnFailure
4. Error Handling: If tests fail and is set to false, it stops all tests. Otherwise, it logs errors and proceeds with the remaining tests.
5. Results Summary: After execution, the tool provides a summary of test results, including successful tests, failed tests, projects with no tests, and any unfinished tests if the execution is interrupted.
