Test Explorer (VS) shows '<Unknown project>'
- Close Visual Studio.
- Delete the
*.testlog
files in: solutionfolder\.vs\solution name\v16\TestStore\number.
I faced the same issue right now. A cleanup helped. As I had cleanup issues with VS in the last time (some DB-lock prevents a real cleanup to happen), my working cleanup was this way:
- Close VS.
- Git Bash in solution folder:
git clean -xfd
Probably it helps.
Neither of these solutions worked for me. I was able to get the test explorer working by closing visual studio and deleting the ".vs" folder. Then reopen the solution and let it rebuild it.
