Testing

Tools used to test the application:

  • ESLint (static code analysis of JS files)
  • Stylelint (static code analysis of CSS files)
  • Markdownlint (static code analysis of Markdown files)
  • Jest (unit tests)
  • Playwright (visual and functional component testing)

Generally, npm test and npm run test:playwright-ct:all should be run within their designated Docker containers before pushing changes to the repository.

Tools

You can run all tests with a single command:

npm run lint && npm test && npm run test:playwright-ct:all

Linters (ESLint, Markdownlint, Stylelint)

Run linters either all together:

npm run lint

or run linters individually:

npm run <eslint|markdownlint|stylelint>

Jest

npm run test:jest

Playwright

Configuration

Test parameters can be tweaked by creating and tweaking .env file.

Running Tests

Run tests:

npm run test:playwright-ct:<all|all-with-update>

You can also run specific tests by passing a path to the test files:

npm run test:playwright-ct:<all|all-with-update> -- -- <match_path>

You can also pass any CLI command to the test runner:

npm run test:playwright-ct:<all|all-with-update> -- -- <cli_argument>

Opening Test Report

After running Playwright tests, test report can be served by using the following command:

npm run test:playwright-ct:show-report

Then open the displayed URL (typically http://localhost:9323) in your browser. Please note that the test report is only available if the tests were run prior to serving the report.
