Reload app.config with nunit

Question

I have multiple NUnit tests, and I would like each test to use a specific app.config file. Is there a way to reset the configuration to a new config file before each test?

Answer 1

I answered a similar question for Powershell. The same technique should work here, simply call the following at the start of your test:

System.AppDomain.CurrentDomain.SetData("APP_CONFIG_FILE", configPath)

EDIT: Actually looks like this is more complicated within a compiled exe - you need to do something like this in order to get the config reloaded.
