Generate 2 parametrized tests instead of test with if-else inside #1140

Description

It's better to avoid conditions in tests.
Currently a parametrized test with if-else condition inside is generated.
The test changes the behavior basing on expected exception (NPE or not)

Expected behavior

It's better to avoid conditions and loops in tests where possible.
Suggestion for here: generate 2 parametrized tests: one expecting NPE and another one for other exceptions.
