Classification of testing
- Static Testing – non executable – work products test/Review- to find – omissions- missing info-loop holes are the flaws in the document – work product can be any doc in process to create the dynamic application- main purpose is to find defects in the very early stage so avoid defects in the dynamic testing stage.
Informal- walkthrough- Technical Review- Inspection - Dynamic Testing – Executable -Applications under test- validate by running the application
Functional levels of testing
1. Unit testing – done mostly by the developers (manual-automation)
2. Integration Testing
3. System testing
4. Acceptance Testing - Static testing- Reviews- Verification
- Dynamic testing – diff levels of testing – Validation
- Difference between Functional vs Non functional
Functional – With out core features- application is not conceded as complete- user cannot work on the application – basically its what the system does- to meet the requirement
Non-Functional – how the system works?
Quality characteristics- enhance compatibility, portability, reliance, etc, any other than the 4 functional levels are non functional
Ex: recovery, security, failover – to validate quality attribute.
Unless client says we will have non functional- so functional testing is non-mandatory.

Change related testing
Adding some maintenance testing with the regular process of the testing
In few companies- they rerun the test as after the fix that us called confirmation testing – to make sure the defect has been resolved- also known as re-testing.
Regression testing is followed after the Re-testing, to make sure the fix does not impact he existing ote modules which are working fine earlier, and not impacted but the new fix added
Regression- is the best candidate for Automation
Also conducted additional when we have environment changes-migration one plat form to other- or new functionality included like updates/upgrades.
