How to fix the CS0433 error?

Assets/UnityTestTools/UnitTesting/Editor/TestRunner/GuiHelper.cs(91,24): error CS0433: The imported type `Mono.Cecil.Cil.SequencePoint’ is defined multiple times

What would be the cause of this error, and how to fix it?

I found a fix to this. ‘Unity Test Tools’ comes with outdated Mono.Cecil.dll and Mono.Cecil.Mdb.dll in its folders, so you just need to replace the files with newer versions.

Also, the Unity Test Tools guys seem to have the issued fixed in a commit, so maybe just downloading a new version would solve the issue.
