What is test coverage in Node.js and why is it important?
Test coverage in Node.js refers to the measure of how much of your code is tested by automated tests. It's important because it helps identify untested parts of your code, ensuring better reliability and maintainability.
How can I measure test coverage in my Node.js application?
You can measure test coverage in Node.js using tools like Istanbul or NYC. They provide detailed reports on which parts of your code are covered by tests.
What are some best practices for achieving high test coverage?
Some best practices include writing tests for all new features, using test-driven development (TDD), and regularly reviewing and updating your tests.
Can you recommend any resources for learning more about test coverage?
Sure! You can check out the official documentation for Istanbul, as well as online courses on platforms like Udemy or free resources on GitHub.
