Software Testing
Software testing is an integral and most critical part of the software development life cycle (SDLC). In today's age, there is software for every possible human need. It is important for software professionals to understand what are the different ways to test software to improve not only the functional quality of the software but also the non-functional and aspects of the software. The tester can follow different approaches to test the software, let's learn about all these possible approaches in detail.
The diagram below represents a hierarchical view of various types of testing a tester can perform on the software. This is not an exhaustive list but covers the most popular software testing types.
Software Testing Types

Software Testing level v/s Software Testing type
Before moving forward, it is important to understand the difference between a test level and the test type.
Software Test levels are the stages of testing like Unit testing, Component testing, Integration Testing, System Testing, and User Acceptance testing a software goes through till it reaches the end-user.
Whereas software testing types are different ways we can test software. Examples of testing types are black box, white box, grey-box testing types. In general, a tester performs different types of testing within the same testing level. A testing level can have white-box and/or black-box and/or grey-box software testing types implemented to thoroughly test the system
