White box testing is a type of testing technique that aims to evaluate the code, design, and internal structure of a program to improve its design, usability, and security. It is one of the two parts of Box Testing methodologies included in software QA testing. The term “white box” is used to refer to the concept of the see-through box. Simply put, the clear box or White Box symbolizes the ability to look through the outer shell of a program and into its inner layout. In this guide, we’ll discuss everything you need to know about white box testing, how it is done, its pros and cons, and the best tools available to do it. When white box tests are carried out correctly, they can identify the following issues and concerns in the code of an application: To provide you with a simple explanation of how experts perform white box testing, we will talk about the process in two steps. The following are the primary tasks testers do when applying the white box testing approach: One of the first things testers will do is study and understand a program’s source code. Since the inner workings of a software application are being tested in white box testing, these testers need to be highly experienced in the various programming languages as well as secure coding practices. Since security is one of the main goals in testing software, testing experts should be able to identify security concerns to prevent attacks from cybercriminals and users who may accidentally insert malicious code into the program without knowing. The next step involves testing the source code of an application to see if its flow and structure work properly. One way testers perform this is by writing additional code so they can test the program’s source code. Testers develop minor tests for every process or series of processes within the app.
