Best Practices For Regression Testing

The Best Practices For Regression Testing

With the growing popularity of agile methodologies, regression testing has risen to prominence as a value-add. Today, most businesses outsource regression testing services and use an iterative, agile approach to software development.

For example, several SaaS service providers are constantly adding new functionality or features with each software update. To maintain performance and verify that newly introduced features affect the final product, these businesses engage an established regression testing organization. Regression testing is primarily concerned with ensuring that a bug patch has been applied to address a code problem.

Obstacles to Regression Testing

Regression testing is a critical component of the SDLC (software development lifecycle). While this form of testing is a necessary component of the software testing process, it introduces several complications.

Time Consuming

Regression testing may be time-consuming, making it even more difficult for QA tests to perform in a short amount of time. This sort of test consists primarily of repeated tests to ensure that testers do not encounter any errors or defects while re-running tests.


Regression tests are prohibitively expensive due to their time-consuming nature. Due to financial limits, businesses must make informed judgments about which test cases to perform. However, omitting regression testing exposes organizations to significant risks by permitting the introduction of problems that threaten business objectives and degrade the end-user experience.


Tests might get more sophisticated because of different newly added functionality and when goods are upgraded. Creating new test cases or adjusting existing ones to account for the current state of a website’s or application’s functionality may be a challenging undertaking.

Regression Testing Best Practices

Automated regression Tests

Each time a new version of the system code is built, regression testing must be performed. However, automated regression testing may simplify and expedite the process, freeing QA testers to focus on complex case-specific tests. Once automated, they may be triggered each time the code control system produces a build. This verifies that nothing has been changed that might undo or repair a prior feature. In 99.99 percent of situations, automation is required in the following areas:

Conducting testing after a minor update or bug fix

Conducting comparable regression tests across a variety of platforms, including several OSs (operating systems), devices, and browsers

Data-driven tests. For instance, to determine how a particular program processes unique input data.

Automated regression tests may be deployed quickly overnight or with manual testing, freeing up significant resources. One of the primary benefits of automating regression tests is that human testers may devote more time to exploratory testing new features and assuring a better user experience (user experience).

Maintain and Revise Regression Packet regularly

The regression pack is primarily a set of test cases that are run whenever new software is upgraded. The scripted tests included in a pack are written with consideration for the prerequisite requirements of older program versions. Ad-hoc or random tests may be included in the pack by testers. Regression tests may be laborious and time-consuming; the last thing you need is to count tests to determine if a defunct feature is still functional.

Pay Special Attention to High-Traffic Routes

Highly trafficked techniques are the most pervasive and frequent use cases for an app. These pathways combine the app’s critical functionality and prominent features. One must first determine the key clients and the common characteristics, characteristics, and partnerships they are most dependent on. Practical regression tests are necessary to include tests that ensure this fundamental functionality operates as intended.

Conduct a Complete Regression Suite Only When Necessary

It is not necessarily necessary to run the whole regression suite on every build. It is prudent to run or execute just the smoke tests and regression testing for any modified modules when doing a minor release. To keep things simple, it seems logical to organize the test cases in regression testing according to the module of the AUT covered by each test. For example, if the release includes a change to the payment methods supported by an online store, it is preferable to do regression testing on the payment process but not on extra features such as locating and adding things to the basket.

Iterative Test Cases

Tests that have previously identified problems and malfunctions are worth including in your regression test suite. On the other hand, programs that pass testing are more likely to be legitimate.

The Most Effective Regression Testing Tools

Numerous regression tests are available to assist Regression Testing Company. The QA experts may expedite the process and adhere to best regression testing practices using these efficient testing tools.

QTP – This test tool enables you to do regression testing on software and environments.

Wrapping Up

In a competitive market, service and product quality continue to be critical to corporate success. User pleasure and approval are a business’s top goals since they are closely followed by brand trustworthiness and, therefore, increased earnings. Using regression testing services and pursuing retesting can ensure that your software is functional, resulting in a significant ROI.
