Unit testing is a critical practice for ensuring code reliability and maintainability. Here’s a guide to mastering advanced unit testing techniques:

🔍 Key Concepts

  • Mock Objects: Use mocks to isolate dependencies (e.g., Mock_Object for simulating external services).
  • Test Coverage: Aim for comprehensive coverage with tools like Coverage_Analyzer to identify untested code.
  • Edge Cases: Focus on testing boundary conditions (e.g., Empty_List, Null_Input).

✅ Best Practices

  • Parameterized Tests: Run the same test with multiple inputs (e.g., Positive_Negative_Values).
  • Test Doubles: Replace real objects with stubs or spies for controlled scenarios.
  • Refactoring Safely: Use tests to validate behavior after code changes.

🛠️ Tools & Frameworks

  • JUnit 5 (Java): Supports dynamic test generation and parallel execution.
  • pytest (Python): Simplifies test writing with decorators and fixtures.
  • Mocha (JavaScript): Integrates with frameworks like Sinon_Js for mocks.
