问题
I have a project setup to use MSTests but they are simply taking too long to load all the the test DLLs, before even loading my project specific DLLs.
I´m on Visual Studio Professional 2015 with Resharper 10.0.1
I´m attaching only part of the the logs down here since stack overflow complaint about limit, but it would be 10 times as bigger, following the same line of these dlls. The total time was around 30s, before my dlls started being loaded, but only a couple of acceptable seconds afterwards.
Is there anyway to optimize this?
EDIT:
Actually, found that some libs are being loaded/unloaded multiple times under different "domains"( which I have no clue of the meaning up to this point)

Edit2:
The pattern I described above is happening a lot of times. Searching for mscorlib.dll on the logs I found 138 matches!!
My hunch is that this is the cause, but I still have no clue of the solution
Thanks

回答1:
Actually, after some research I found out that the main culprit was the usage of TestSettings1.testsettings instead of test.runsettings.
After a bit of time adapting the tests, (mostly due to the lack of Global DeploymentItems, which I solved using a base class), the tests are now running under 10s which is way better.
Think there´s still room for improvement though, but I´m at least satisfied for now
