Running tests with reduced privileges
One of my project's unittest cases depend on not being able to create file and throwing exception instead. As it runs as administrator, it always succeeds, making test fail. Is it somehow possible to launch unittest with reduced privileges?
One way is to run unittests in wrapper script with lowered 'runas /trustlevel' but runas does not return correct error code that launched application returned. It is also possible launched script to communicate back success/failure by generating result file but it feels cumbersome. Although i probably need to go this way if appveyor itself doesn't support dropping privileges somehow that i missed.

There is no built-in support for running with reduced privileges.
I've found psexec.exe could be used for that: http://www.techsupportalert.com/content/easy-ways-run-windows-progr...
It's actually available on build workers in C:\Tools\PsTools and should be in PATH already.

Thank you for answer.
Tried psexec, it had another problem -- limited too much, now testcases that must succeed to open file, fail :)
Anyway, managed to circumvent 'runas /trustlevel:0x20000' error level problem: google test runner generates junit XML output that can be queried for failures with powershell.

Maybe someone else will find this useful, so I'll leave it here.
I tried many different ways including psexec and runas, nothing worked actually.
Finally I found quite complicated way of doing that (using openssh). But at least it works well and allows you to control the privileges like you need. Besides, it requires zero configuration from Appveyor side. The example can be found here https://github.com/yandex-qatools/postgresql-embedded.
