QA testing encompasses a variety of methodologies and approaches for testing coverage. It's imperative to understand these methodologies to choose the most suitable testing strategies. With a sound knowledge of types of QA testing, discover how online IT boot camps help you become a software tester and can be your ladder to success with no experience.

Manual Testing
Manual testing involves human testers executing test cases without using automation tools. This approach is highly effective in situations where human intuition is crucial, such as exploratory testing and usability testing.
Automated Testing
Automated testing involves using testing tools and scripts to automate repetitive and time-consuming tasks. This is also appropriate for situations requiring the repeated execution of test cases, regression testing, and performance testing.
Functional Testing
Functional testing is focused on verifying that every function of the software is working properly. This includes unit testing, integration testing, system, and acceptance testing.
Non-Functional Testing
This testing technique assesses non-functional aspects such as performance, security, usability, and reliability of the software. For example load testing, stress testing, and security testing.
Black Box Testing
In this technique, the software is treated as a black box to test the functionality while being unaware of the internal code or logic. This approach focuses on inputs, outputs, and system behavior.
White Box Testing
Contrary to black box testing, white box testing involves testing with knowledge of the internal code, logic, and structure of the software. Testers design test cases based on understanding the software's internal workings.
Regression Testing
During the development phase, regression testing plays a crucial part in identifying and fixing defects. This approach ensures that new code changes do not negatively impact the existing functionalities.
