Extreme Programming, or XP, brought many insights into software development, but at least two are important for purposes of code inspections. Early identification and resolution of defects: Software inspection allows developers to identify and resolve defects early in the development process, which can save time and resources by preventing costly rework or delays later in the project. d.

Software Inspection also plays very effective and important role in identifying various types of bugs rather than that of software testing does. It is not always possible to go through every line of code with several parameters and their combination to ensure the correctness of the logic, side effects and appropriate error handling. LearnVern is a training portal where anyone can learn any course in vernacular Once the test planning is done, the development of test cases begins.
