Software Testing Battle #2: Risk-Based VS. Regression


Regression Challenges

Many software QA testing companies build their regression test beds accumulating test cases of several releases. Test beds’ execution is based on available time, data and test environment. While the testers running such regression test sets gain skills from practice, they don’t have any specific regression testing skills get in trainings intended to help with advanced testing methods’ adoption. This can results in such gaps as:

Addressing these challenges requires undivided attention paid to each point. Still, if such challenges exist, the question arises how companies today should manage regression testing needs. Most of them adopt the risk-based testing approach with limited risk assessment which suggests regression testing is done based on resource and time availability. Such approach raises the chances to miss some regression defects and therefore increases the cost of production support just as well. If you have no efficient regression testing strategy, this will mean:

Risk-Based Role

Risk-based testing methodically addresses regression testing complexity and size. Everybody knows there are theoretically infinite possible ways the product may fail. Practically, it’s the same about apps as well. However, most testers and business users tend to test their apps for each practical use which ends up in a set of challenges as given above. However, these complexity and size issues can be solved by risk-based testing means like:

Despite the above positives, this type of software QA testing is used across companies in a rather limited manner because of two reasons:

Heading for Success

Test managers have already known about the risk-based testing concept for a while. Though, its usage is still limited despite its helpfulness for more quantitative quality risk measurement and reduction of regression testing effort.
