Different Types of Software Testing – Part 2

Different Types of Software Testing – Part 2


In the first part, we explained several types of software testing. In this part, we will continue to briefly explain what other types of software testing exist and what they do.

9. Performance testing

As the name suggests, this is a type of software application testing that focuses on testing speed, stability, reliability, and scalability under a specific load.

The goal of this test is to estimate what the output of the application will be. What will be the data transfer speed, network bandwidth usage, how many application users will be able to serve without breaking, how much memory will be used, or how long will be the response time to commands.

10. Regression testing

Regression testing is a type of testing that checks to see if new code changes will break an application and if the application will use too many resources. Regression testing is nothing more than repeating tests that have already been run, either all or specially selected to make sure that the current functionalities are working properly.

11. Sanity testing

This type of testing is usually performed after bug fixes. Checks if all bugs are fixed and if there are any other problems. If the sanity test fails, the build is rejected to save time. Sanity testing is a subset of regression testing.

12. Security testing

Tests for software or application vulnerabilities. The goal of this type of testing is to find potential omissions and weaknesses that could lead to data loss or leaks of sensitive data outside the company.

Security testing not only helps to check system or application vulnerabilities but also helps developers find certain problems and fix them through code.

13. Single user performance testing

Also called client-side performance testing. Evaluates Key Performance Indicators (KPIs) on the client-side such as response time. It takes into account all factors that may affect the end-user experience at all levels including client devices.

14. Smoke testing

This type of testing focuses on the stability of the software application. Checks that all critical program functions are working properly.

Smoke testing is performed post software build, before any functional or regression tests. The goal of smoke testing is to reject software applications with malfunctions so that the QA team would not waste time testing faulty software applications.

15. Stress testing

The operation of the application is tested under conditions that are significantly more difficult compared to the normal operating conditions of the application. The goal of this type of testing is to measure the robustness and error handling capabilities of the software. It is also called endurance testing.

16. Unit testing

This type of testing checks smaller pieces of code to determine if parts of the program are working properly.

Unit tests are usually automated tests written and run by software developers to make sure that a certain part of the application (unit) meets expectations. A unit can be a complete module, but it is usually an individual function or procedure. In object-oriented programming (OOP), the unit is usually the entire interface.

17. White-box testing

It is also called clear box testing, open box testing, transparent box testing, code-based testing, and glass box testing because the code is visible to testers. Internal structure and design are tested to check the flow of input-output data and improve design, security, and usability.

Software testing allows you to identify bugs and errors on time, before the delivery of the software product, which is why it is very important. Properly tested software product ensures reliability, security, and high performance as well as customer satisfaction.
