What is PHP unit testing coverage and why is it important?
PHP unit testing coverage measures how much of your code is tested by unit tests. It's important because it helps ensure code quality and reliability.
How can I measure the coverage of my PHP unit tests?
You can use tools like PHPUnit with the --coverage option to generate coverage reports, showing which parts of your code are tested.
What is a good coverage percentage to aim for?
Aiming for 80% coverage is a common goal, but it's essential to focus on testing critical parts of your application.
Can high coverage guarantee that my code is bug-free?
No, high coverage doesn't guarantee bug-free code. It indicates that your code is tested, but tests must also be meaningful.
What are some best practices for writing unit tests in PHP?
Some best practices include writing tests for small units of code, using descriptive names, and keeping tests independent from each other.
