Bug Unity Test Tools. NullReferenceException problem.

Hi, guys.
I have several int tests in my project. It worked nice.

Bit I update Unity to 2017.1.0f3 version and start to take problem with my Unity Test Tools asset.

First of all, it was error in Example/.../SampleTest.cs file. I deleted it.

Next i have error when try to Run all testes from Integration Test Runner or try to run single test from Hierarchy:

Spoiler: NullReferenceException
