White Box Testing- Introduction

White box testing is a software testing technique that involves testing the internal workings or code structure of an application. It is also known as structural testing or glass box testing. In white box testing, the tester has access to the internal code and is aware of the software’s internal structure, design, and implementation.

The primary objective of white box testing is to verify that the code is written according to the design and meets the specified requirements. It involves testing at the unit, integration, and system levels. White box testing can be performed manually or using automated testing tools.

The advantages of white box testing include its ability to detect hidden errors that may not be caught by other testing methods, its ability to optimize code and improve overall software quality, and its ability to reduce testing time and costs by catching errors earlier in the software development life cycle. However, white box testing has some limitations. It requires a deep understanding of the software’s internal workings, which can be time-consuming and costly to develop. It also has the potential to introduce bias into the testing process if the tester is involved in the software’s development.
