Question 3

What are the different types of software testing?

Accepted Answer

There are several types of software testing, each serving specific purposes. Based on the particular testing methodologies applied, software testing can be divided into manual testing and automated testing:

Manual Testing	Automated Testing
Human testers execute test cases step by step	Scripts and tools are used for test execution
Complex scenarios, exploratory testing	Repetitive tasks, large-scale testing
Thorough but time-consuming, prone to human errors	Efficient, provides broader coverage, faster feedback
Minimal coding required	Requires coding for script creation and maintenance
Manual updates and maintenance	Ongoing maintenance of scripts and test environment

In the age of AI, further software testing categorization can be discerned, namely black box testing, white box testing, and gray box testing.

Technique	Description
Black Box Testing	Focuses on testing the functionality of the software without knowing its internal code or structure. Testers simulate user inputs and validate outputs.
White Box Testing	Involves testing the internal code, structure, and logic of the software. Testers have access to source code and design specifications for thorough testing.
Gray Box Testing	Combines elements of both black box and white box testing. Testers have partial knowledge of the internal code and use it to design comprehensive tests.
