Unit Testing #define Directives in Visual Studio
I have some methods in my codebase that utilize the `#if DEBUG` preprocessor directive to provide specialized behavior that differs between the debugging environment and the production environment. I would like to ensure that I have unit tests that validate both of these paths.
**Is there a way to do this in Visual Studio without needing to re-run the tests from a different environment?** Something like an Attribute that can be attached to the test method? MSTest or xUnit solutions would be preferred.
I tried simply having a RowData/InlineData and using the method parameter to #define inside of an if block, but that is explicitly disallowed:
```
if (debugTestState)
{
#define DEBUG
}
else
{
#undef DEBUG
}
```
... results in:
