I want to know why the regression defects are hard to deal with. Can anyone please tell me that.
Regression testing involves again testing the existing functionality to ensure that the recently introduced feature would not break it.
When any bugs are observed to exist as a part of a bug fix, they are classified as regression bugs. For example, let’s assume that your login page has some bugs and the developer has fixed them. Today, the login page is running smoothly, but the authentication page is triggering a validation or other bug that did not happen before. A fix on the login tab may have triggered the latest error. This is a regression defect, and it is necessary to deal with it to produce a more stable product on the market.
Various factors that define the regression bugs are hard to deal with:
Handling regression errors requires a lot of work, and both the company and the customer invest a lot of money in invoicing an employee just to repeat the same job.
Developers are given very little time to fix newly discovered bugs, and the rush to fix them sometimes results in developers implementing some fixes that may not be appropriate based on best practices or coding requirements.
Repeated testing of the same component not only takes time but also becomes irritating at a time where a bug fix leads to another new bug. Slow distribution often becomes a hurdle for the tester to write successful test cases.
A circumstance can occur in which defects fixed in the current sprint can cause any further defects in the previous sprint. It must be assured that regular tests are carried out on the previous sprints as well as on the part of the application already in development, thus driving up the cost of maintenance.
