Regression testing is the testing of a previously tested program. It is done to make sure that changes made to it do not cause defects in the part of the program that has not been changed. In fact, this test is used to check the correctness of additions and make sure that the program continues to meet the requirements set after the changes and successfully interacts with other systems. It can be done manually, or you can figure out how to automate the process. Our article will tell you more about regression automation testing and answer the question of how to automate it.

Why Do You Need Regression Testing?

Refinements and changes to applications are frequent. This is due to the dynamics of IT systems and changing user needs. Adding new functionality, reworking old one, adjusting to an updated browser or operating system, fixing bugs — this is often a continuous process in the life cycle of any software. But you should understand that any revision can cause errors. Even after a performance test, where most bugs are found and fixed, there is a risk that others may appear.

Improvements and changes to the system may affect its performance or part of the previously developed functionality. In such cases, regression testing is recommended. It is advisable to initiate it every time after adjusting the program or site, which may include fixing defects and other major changes. Also, it is recommended to perform regression load testing if the number of system users has grown significantly during the operation of the software.

Process Automation

If the software is subject to frequent changes and revisions, the need for the same tests can increase significantly. To save time, it is recommended to switch to automated web regression testing, which reduces testing time without compromising the quality of the work. To automate this process, you may use the Zappletech services.
