Testing Pyramid

The Testing Pyramid is a concept used in software development that suggests a balanced approach to testing different types of software. It visualizes a structure with three layers: at the bottom are unit tests, which check individual parts of code; in the middle are integration tests, which ensure those parts work together; and at the top are end-to-end tests, which verify the complete system functions as expected from a user’s perspective. By focusing on more unit tests and fewer end-to-end tests, developers can catch issues early and reduce costs while maintaining quality in their software.
