About Manual Testing
Manual testing, as the term suggests, refers to a test process in which a QA manually tests the software application in order to identify bugs. To do so, QAs follow a written test plan that describes a set of unique test scenarios. The QA is required to analyze the performance of the web or mobile application from an end user’s perspective. QAs verify the actual behavior of software against expected behavior, and any difference is reported as a bug.
Types of Manual Testing
1. White Box Testing
White box Testing, also known as glass box or transparent testing, is an approach in which the QA is familiar with the internal code or structure of the application. It is primarily used for unit testing. White box Testing also covers specific techniques like data flow testing, control flow testing, decision coverage, and path testing, and a few others.
2. Black Box Testing
Black-box testing is a test approach in which the QA doesn’t have any knowledge about the underlying code or structure of the application. The QA interacts with the software application just like an end-user to test its functional and non-functional behavior. This helps to discover some bugs typically overlooked in the earlier stages.
3. Grey Box Testing
Grey-Box test approach is the combination of both white box and black box testing techniques. The main aim of this approach is to identify any bugs present either due to inappropriate usage or any structural flaws.
