After running unit tests, I used to find two files in the Tests folder for the Derived Data of Xcode - StandardOutputAndStandardError.txt and TestSummaries.plist files. However, in Xcode 10 I'm unable to find these files. How can I get the test logs in Xcode 10.
StandardOutputAndStandardError.txt file, you are looking for, is now located in:
Derived data
\your project folder
\Logs\Test
\.xcresult file
\Diagnostics
\<YourAppNameUITests folder>
\<YourAppNameUITests folder>
again and there it is.
For <YourAppNameUITests folder>
there is also a folder with log from simulator.
