Tests fails when running whole class or a few classes using OpenSDk

[galinareznikk]

I have 2 classes with a few tests in each of them.

when I'm running the single test from class 1, the test is passing But when I'm running the whole class that contains that test, the test fails

same when I'm running class with a few tests, and they are all passing but when I'm running 2 classes together the second class tests fails.

I've attached the classes code.
