What is White Box Testing?

One of the most important testing types in the software testing process, white box testing is performed to verify the flow of input-output by testing the internal structure, design, and code of the desired software. It is mainly concerned with improving the design, usability, and security of software.

White box testing is also known as clear box testing or glass box testing as the software code is visible to testers here. It is largely based on the inner workings of an application and revolves around internal testing.

For efficient white box testing, you can avail of our quality services and increase the speed of your software to the market. We, at Sapizon Technologies, are one of the best software testing companies.

By actively providing our services in this domain, we have helped our clients deliver defect-free software applications and increase their up-sales as a successful result. Our team of software testers possesses the skills and experience to carry out various testing methods with precision.

Through the implementation of vigilant testing strategies, we identify defects in the internal part of a software application and fix them in minimal time. This has enabled us to gain the trust and loyalty of our clients.

What do you Check-in White Box Testing?

Here are a few pointers that explain the key aspects of testing in white box testing:

· Testing the code for internal security holes.

· Identifying broken or poorly structured paths in the coding process and fixing them.

· Checking the flow of certain inputs through code.

· Verifying the expected output.

· Testing the functionality of conditional loops.

· Testing each function on an individual basis.

This type of testing can be performed at system and integration levels of software development. One of the main purposes of white-box testing is to verify the workflow for the desired application.

This involves verifying the output you get as a result of running a function with a predefined input. If the result you get is expected, you can conclude there are no bugs.

Implementing White Box Testing:

White box testing is implemented by following the below process:

Understanding the Source Code:

As white box testing involves testing of the internal part of an application, the testers must be familiar with programming languages that are used in the applications they are testing.

Along with this testers person must also be aware that they need to implement secure coding practices. Security is one of the most important features in a software app and it is imperative to ensure the security requirements of your application are met.

Here, testers should be able to find security loopholes and prevent attacks from hackers and cyber-criminals that can compromise the security of your application either with the intent to do so or without.

Create Test Cases:

Once the testers have understood the source code of the application, they can move on to the next time that is creating test cases. Developing test cases involves writing test scripts for testing each fundamental feature of software applications with respect to different test scenarios.

Execution of Test Cases:

Once the test cases are compiled and the test environment is ready, software testers can begin the process of execution. Execution of test cases is carried out based on the priority of each. Test cases that are highly prioritized are performed early followed by the remaining.

The key to the successful execution of test cases is that the software testers must possess intricate knowledge about the application and its code. More often than not, collaboration with developers is very helpful.

To Conclude:

White box testing basically involves testing the internal components of an application that are not visible. Unit testing, penetration testing, and mutation testing are some of the white box testing types. These tests are prominent and concern some of the important features of an application.

As one of the leading software testing companies, we offer our services to clients across various industrial domains.
