Regression Testing can be described as an approach to testing software to verify that the recent program or code modification has not adversely affected the existing features. Regression Testing is the full or partial set of previously completed test cases that are then re-run to make sure that the existing functions work as intended. Anyone looking to use Selenium automation testing course. Must understand the basic principles that test, as well as the methods of black-box testing, and more. A knowledge of scripting languages, like, JavaScript is a huge benefit of working in an domain that involves software tests.
The testing is conducted to ensure that any new changes to the code will not cause any adverse effects to the function that are already in place. It makes sure that the older code will still function after the most recent code changes are implemented.
Regression Testing is a must
It is the Need of Regression Testing mainly occurs when there is a need to alter the code, and we must test whether the new code impacts the rest of the software or not. Additionally, regression testing is required when a new feature is introduced to the software application , and to fix the problems as well as performance issues fixing.
How to conduct Regression Testing
To be able to carry out the Regression Testing procedure We must begin by debugging the code to find the flaws. When the bugs are discovered and the necessary changes are implemented to correct the issue The regression testing process is carried out by selecting the appropriate test cases within the test suite that cover the affected and modified parts in the program.
Software maintenance is an action that includes improvements, errors corrections, optimization, and removal of current features. These changes could make the system work improperly. This is why Regression Testing is necessary. Regression Testing can be conducted by using the following methods:

Retest All
This is among the ways to perform Regression Testing where every test in the current test suite or bucket should be executed. This can be very costly as it takes a lot of resources and time.
Selection of Regression Tests
The Regression Test Selection is a technique whereby selected test cases of the test suites are used to see if the changed program affects the software or not. Test cases are classified into two categories: reusable test cases that could be reused in subsequent testing cycles as well as obsolete test cases that cannot be used in future cycles.
Preferences for Test Cases
Prioritize test cases based on the impact of business, crucial and frequently used functions. Selecting test cases according to importance will drastically minimize the regression test suite.
Selection of test cases to be used to test regression
It was discovered by analyzing industry data that a large portion of defects that customers reported were the result of last minute bugs that caused adverse effects. Hence, selecting which test casefor testing regression is a skill and not an easy task.
Effective regression tests can be conducted by choosing the following cases for testing The following test cases are available:
- Test cases that have frequent imperfections
- Functions that are more apparent to users.
- Test cases that test the fundamental capabilities of the product
- Test cases for Functionality that have undergone more recent modifications
- Every single Integration Test Cases
- All Test Cases that are Complex
- Test cases for Boundary Value
- A selection of successful test cases
- A selection of failure test cases
