Software Testing 101

The testing pyramid is a concept in software engineering that illustrates the ideal distribution of different types of automated tests. It is often used as a guideline to encourage teams to prioritize certain types of tests over others. The testing pyramid typically consists of three layers: unit tests at the base, followed by integration tests, and finally, end-to-end tests at the top. The rationale behind this structure is to create a robust and efficient testing strategy that ensures high test coverage and fast feedback loops.

1. Unit Tests

• These are small, focused tests that verify the behavior of individual components or units of code in isolation.
• They are typically written and executed by developers and are usually fast, reliable, and inexpensive to run.
• Unit tests help catch bugs early in the development process and provide a solid foundation for the overall test suite.

2. Integration Tests

• These tests focus on verifying the interactions between different components, modules, or services within a system.
• Integration tests ensure that various parts of the system work together correctly and that data is transferred between components as expected.
• They are broader in scope compared to unit tests and…
