What is confirmation testing? What are its pros and cons?

It is a type of software testing method that ensures faultless software and boosts the rate of the application’s success. In confirmation testing, the assessor rechecks the previously detected error or bug to ensure that the respected development team member solves the fault or error. A 100% error-free application is not possible but the assessment team tries to identify as many defects as they enhance the working of software applications.

Confirmation testing protocol or procedure

  1. The application is tested by the testing team to if finds any bug, then they forward it to the assessment team and send it through the bug resolution process i.e. First, we can fix the bug, or the bug can be ignored, and last, we can hold it.
  2. The assessment team then redesigns the program and then retest the bug by the testing team to know whether it is resolved or not. This process is known as confirmation testing.
  3. After confirmation testing, regression testing of the application starts.

Characteristics of confirmation testing

  1. It is pre-planned: Confirmation testing is already scheduled to test and require additional contribution from the verification team and the development team both. 
  2. Repetition of test cases: The bugs reported can be tested by the same case test. It decreases the workload of testers by not writing again and again test cases.
  3. Success of application: Confirmation testing improve the success ratio by confirming the error-free software application with all serving requirements.
  4. Ahead of Regression testing: Confirmation testing should always done prior to regression testing because it checks that the functionality of other modules does not get affected by resolving bugs.

When to perform Confirmation testing?

  1. To fix a bug, after informing the respective member of the development team about the bug to be fixed and confirm whether it is resolved or not.
  2. Confirmation testing should performed prior to regression testing.
  3. When a customer requires highly successful software.

Pros of confirmation testing

  1. Boost performance: The working and performance of the application increase as there are fewer chances of a bug and confirmation testing re-tests the bug which enhances the quality and functionality of an application. 
  2. Repetition of same case tests: In confirmation testing, we do not need to write test cases repeatedly. The corresponding test cases can be used to evaluate the bug.
  3. Identification of defect: The only aim of confirmation testing, to recheck the bugs identified earlier to improve the quality of the software.
  4. Realm of testing: The aim of confirmation testing remains fixed.

Cons of confirmation testing

  1. Costly: Confirmation testing takes more time period, efforts, and money which everyone can’t spend.
  2. Rebuilding the build: After identification of the error or bug, the assessment team has to build test cases until the bug is unresolved. 
  3. Affects the behavior of the application: To fix the bug, changes are made which result in other functions behaving differently. It then demand more time to solve again and fix.
  4. Regression testing: Regression testing is necessary to perform just after confirmation testing as it might be alterations in other modules in fixing the bug. Hence, retesting has to be done which consumes more efforts and time. 

Final Thoughts

Finally, confirmation testing serves as one of the most integral stages in software testing. Its goal is to enhance the quality as well as bug-free software to upsurge in application successes. Nonetheless, it may prove expensive, may need several rebuilds, alter application behavior, and require more regression testing. It is vital to have a balance between quality and resources by considering when to use confirmation testing.
