Boundary value analysis(BVA)

BVA means testing the edges of Input ranges.
When the application allows values only within a Range, We do not test the all values .We do test the smallest value ,biggest value and values just near them because mistakes usually occurs at the edges.
Because most software bugs happens at minimum ,Maximum and around the edges
EX: Age must be 10 to 40

we usually test 9,10,11,39,40 and 41 values

we accept 10,11,39 and 40 value
we do not accept 9 and 41

1.Smoke testing:
Smoke testing is basically performed before actual test begins .Smoke testing means quick test performed on critical or high level functionality of the new build.
EX: Login page, Navigation ,Credential testing
2.Sanity testing:
Sanity test will be done when small fixes or changes done in new build .To ensure that new fixes or changes working as expected.
ex: Add product to cart, Apply coupon
3.Regression testing:
Regression test will be done when new feature added(fixes or update the code) to application .To test to ensure the existing version of functionality is working fine.
4.Whitebox testing:
White Box testing usually done with the help of developers .To test internal structure of the code we call it as Whitebox testing . Technical knowledge required to test this.
5. Block box testing:
Block box testing done by Testers. This technique not required technical knowledge. Product knowledge (Requirements)is enough to test.
6.Monkey testing:
Monkey testing is Software testing technique in which application test Randomly or unstructured testing .
7.End to End testing :
It is the method where we test entire application flow from start to end ,Just like a real user .It covers and verifies all integrated components work together
correctly.
8.Retesting:
It is focus only on Failed test cases ,To test specific test cases are working as expected or not. Not whole application.
