Answer / markusorelius

These are different test techniques, which are applied in a
structured way to the target software. They arise from
understanding where software typically fails, and why.
These technicques are very effective and efficient in
structuring a test for a specific kind of functionality.
You need to choose the correct one to apply in every case.
You do this by understanding what the particular item's
function is and thus how to test it with the most efficient
and effective method.

Answer / kishan prasad

Boundary Value analysis is the testing carried out at the
boundary values. Ex: if any application is said to have some
2-3 levels of values with which it should behave
differently, the tester exclusively tests those boundary
values specifically with decimal values, characters
etc.(like <40% fail, 40% to 50% third class, etc...
