Shift-Left Testing Techniques

Unit Testing: Writing unit tests that verify the functionality of individual units of code (functions, classes).

Integration Testing: Testing how different modules or components of the system work together.

API Testing: Testing the functionality and behavior of APIs used by your application.

Static Code Analysis: Utilizing tools to analyze code for potential issues like syntax errors, security vulnerabilities, and coding best practices violations.

Test-Driven Development (TDD): Writing tests before writing the actual code for a feature. This forces developers to think about the functionality from a testable perspective.
