Test case levels

[Me]:-  What are test case levels?

[Guruji]:- Test Case levels are indications on test cases which tell you what;s the priority of the test case. Visualize it this way. If i were to give you an application and use it, then the most used scenario would be my most high priority as that would be the case that would be run every time and i would not want a failure there.

[Me]:-  WoW!!! So is there a base rule which tells me what test case classifies for a particular level?

[Guruji]:- Well, there is no such base rule. But yes, in general the test case levels can be clearly classified based on some points

And those points would be

Level 0 - (Acceptance tests - a.k.a BVT) - L0s passing would indicate a valuable build to use for extended testing.


BVT (Determines the usefulness of this build to test).
Area Base valid Functionality tested at breath.
May contain L1 classified Cases as determined by the feature team.
Typically Automated (No manual)

Level 1 - (Validity Testing - Product/Application works) -   L1s passing would indicate valuable build for internal customers/partners.

Area valid Cases tested at depth.

Base Integrated System Tests

Breadth Pass

Level 2 - (Invalid/Error/Boundary Testing) - L2s passing would indicate valuable and robust build for internal customers/ partners. Build behaves acceptably when used incorrectly.

Extended Integrated System Tests
Boundary Conditions
Invalid/Error Condition
Automated or Manual

Level 3 - (Extreme - Robustness Testing) - Product/Application may still ship, even if a problem was found with this type of test, depending on the scenario. Level 3 testing is very important for understanding the true quality of the product.

Depth/Robustness Stabilization

Complex repro - Unlikely extreme scenarios.

Fail and recover scenarios (denial of service - security breech..)

Fault Tolerance.

Ad / Hoc - Gorilla testing.

Extreme deployment and load scenarios.

Extreme Stress/Extreme Scalability
