Change execution directory

Question

I'm playing around with stryker.net but get a file not found exception, which is not unusual, because I've got some dependencies which are stored in an other directory, where my output files are copied to. How to change the test-directory of stryker? The specific file which it's searching for is one of those dependencies.

    Unhandled exception. System.IO.FileNotFoundException: Could not find file 'some.dll'.
File name: 'some.dll'

Answer 1

This depends on how you execute Stryker (from the test folder or from the repo root) - but basically you can do 2 things:

• configure the name of the target project using --project
• configure the path to the test project using --test-project
