Testing is an important part of the software development lifecycle (SDLC).
It helps ensure that your application is reliable, stable, and less prone to bugs (nobody is 100% immune).
Pytest is a popular testing framework to help you write and run tests for Python.
Testing helps identify bugs and errors in the software before its released to end users.
Unit Tests
Tests that focus on testing individual units or components of code in isolation.
The goal is to ensure that each unit (function, method, class, object, instance) works as expected, independently.
It may seem like the smallest and insignificant type of testing, but it is one of the most important.
Integration Tests
Integration tests focus on testing the integration and interaction between different units or components of your code.
The goal is to ensure that all these work together as expected when integrated into the software.
End-End Tests
E2E testing helps you verify the behaviour of a complete system or application, as a whole.
They are designed to simulate the actions and behaviours of an end-user, from the start of interaction to the end.
Regression Tests
Tests to ensure that changes made to a software application do not cause unexpected side effects or break existing functionality.
Regression tests involve re-running previously executed test cases to ensure that the application still works correctly after changes.
Security Tests
Testing to identify vulnerabilities, weaknesses, and potential security risks in an application or system.
This is important because it helps ensure that sensitive information, data, and systems are protected from unauthorized access, use, or modification.
These can include penetration testing, vulnerability scanning, and security code analysis.
Performance Testing
Testing to check the performance and scalability of your application.
This helps ensure that your application can handle a large influx of users or transactions without experiencing performance degradation or failures.
This may include load testing, stress testing, and endurance testing.
