In this article, we learn what is error seeding or defect seeding, and progressive testing.
Error Seeding or Defect Seeding In Software Testing
Error seeding and mutation testing are both error-oriented techniques and are generally, applicable to all levels of testing.
Defect seeding is a practice in which defects are intentionally inserted into a program by one group for detection by another group.
The ratio of the number of seeded defects detected to the total number of defects seeded provides a rough idea of the total number of unseeded defects that have been detected.
Defect seeding is done to find the capabilities of a testing team. A testing team will add a few defects in the application and the other one has to find out all the defects in that.
Defect Seeding is implanting the defect intentionally in the code to test the unit test case or specific condition or exception handling.
Different purposes of defect seeding:
To verify how the application is responding when the respective error occurs.
Determine whether the build is properly tested or not.
Determine the capability of testing experts in the QA team.
Progressive Testing In Software Testing
Progressive testing is quite functional. In this, we test the application with old test data. It is a first test that rolls down to a regression test on retesting.
When an application with a hierarchy such as a parent-child module is being tested, the related modules would need to be tested first.
Progressive testing also known as incremental testing is used to test modules one after the other.
When an application with a hierarchy such as a parent-child module is being tested, the related modules would need to be tested first.
Progressive testing focuses on new functionality and old functionality and proving that it works as per the requirements of hierarchy modules.
Whereas regression testing focuses on proving that existing functions of the application are not broken by the addition of new code.
