Nowadays, any software technology company pursues the goal of providing the best service to customers by developing Web App and Mobile App. In the software development process, Testing and Debugging are two important phases in the process of creating a high-quality application.
In this article, you will learn about Testing and Debugging in detail, along with some other useful support tools.
1. What is testing? What steps does the Testing process include?

Testing is a process that helps developers detect possible problems before the application goes live. The Testing process can be performed using automated or manual methods.
The Testing process includes 8 main steps:
Understand requirements: Testers need to clearly understand the requirements before testing.
Test planning: Developers need to create a test plan to determine appropriate testing goals, resources, and methods.
Test Case Deployment: The developer builds test cases based on pre-existing requirements and plans.
Review the Testing Plan: Testers need to review the scope outline, objectives, and testing methods. In addition, Testers also need to consider the testing environment, test products, and expected results.
Set up a testing environment: Testers need to build a testing environment with hardware, software, and other necessary components.
Conduct testing: Carry out the testing process, record results, and detect errors.
Error tracking: During testing, it is necessary to detect and track errors as well as find ways to fix them.
End of testing: Evaluate the testing process, record the results, and end the process.

Debugging is the process of detecting errors, determining their cause, and correcting them. Debugging is quite complicated and requires tools to help with debugging, contributing to creating high-quality software products.
The Debugging process includes 6 steps, specifically as follows:
Error detection: First, the programmer will try to find the error by looking for clues, reviewing the code, and looking at the output.
Error reproduction: After detecting an error, you can reproduce the error to find the causes of the error.
Isolate the cause: After reproducing the error, the developer needs to isolate the cause of the error.
Fixing errors: Once the cause of the error has been identified, the developer can fix the error using many methods such as correcting the necessary code and data.
Test the corrected application: To ensure the application works properly after fixing the error, the developer needs to test it again.
Save the fix: Developers need to record the changes they make for future debugging.

Testing and Debugging are two necessary steps to ensure software quality. The table below shows some of the core differences between Testing and Debugging.
| Testing | Debugging | |
| Target | Identify application errors | Fix application programming errors |
| Knowledge requirements | Most tests do not require knowledge of source code | Debugging requires an in-depth understanding of the source code |
| Implementer | Made by tester | Conducted by software developer |
| Form | Testing can be done manually or automatically | Debugging is done manually |
| Implementation time | Testing is done after the developer writes the code | Debugging is carried out after testing fails |
