Hi Webies, in the below article I'm going to explain what is Defect Detection and Defect Prevention.
And also Role of a tester in doing the same.
What is Defect Detection????
In Defect detection, role of a tester include Implementing the most appropriate approach/strategy for testing ,preparation/execution of effective test cases and conducting the necessary tests like - exploratory testing, functional testing, etc.
To increase the defect detection rate, tester should have complete understanding of the application. Ad hoc /exploratory testing should go in parallel with the test case execution as a lot of bugs can be found through that means.
What is Defect Prevention????
In Defect prevention, developers plays an important role. In this phase Developers do activities like – code reviews/static code analysis, unit testing, etc. Testers are also involved in defect prevention by reviewing specification documents. Studying the specification document is an art. While studying specification documents, testers encounter various queries. And many times it happens that with those queries, requirement document gets changed/updated.
Developers often neglect primary ambiguities in specification documents in order to complete the project; or they fail to identify them when they see them. Those ambiguities are then built into the code and represent a bug when compared to the end-user's needs. This is how testers help in defect prevention.
