Today I will explain you about QA and Tester, and what is the basic differences between us.
Quality Analyst: Who analyses the quality of the product is known as Quality Analyst. The role of QA is bug prevention. QA must have the knowledge of all the documents which are used in the project from the initial level to the final level and familiar with all the phases of development as well as testing.
Software Tester: Testing is the procedures through which use to identify the correctness, completeness and quality of the developed software. The all procedures followed by the person known as Software Tester.
The main role of tester is to find the bug in the application or we can say that tester proves the presence of bug, not absence.
Difference b/w us: Tester role is to execute the script and make it fix or resolved by developer as soon as possible. Whereas QA analyses the hole application from initial level to final level. The main differences b/w QA and Tester is that QA aimed to bug "prevention" on the other hand tester aims for bug "detection".
