To test code coverage in PHPUnit, you need to follow these steps:

  1. Install PHPUnit: Run the following command to install PHPUnit using Composer: composer require --dev phpunit/phpunit
  2. Configure PHPUnit: Create a phpunit.xml file in the project directory and add the following code: tests src This configuration sets the test suite directory, includes the code in the src directory for coverage analysis, and specifies the output formats as HTML and text.
  3. Run PHPUnit: Execute the following command to run PHPUnit with code coverage analysis: vendor/bin/phpunit --coverage-html=coverage This command runs PHPUnit and generates a code coverage report in HTML format. The --coverage-html option specifies the output directory for the coverage report.
  4. View the coverage report: Open the generated HTML report in the coverage-html directory to view the code coverage report. The report shows which parts of the code were covered by the tests and which parts were not.


By following these steps, you can easily test code coverage in PHPUnit and analyze the effectiveness of your tests.
