How do you instruct NUnit to load an assembly's dll.config file from a specific directory?
.net, app-config, configurationmanager, nunit, unit-testing
Solution
The NUnit blog explained of why the config files load the way they do. Basically what they said was that NUnit lets the framework handle the config files and doesn't do any of the management.
You can also use the `testProject.config` file that would be loaded in your case, to reference the config files for each of the assemblies. Using the appSettings file attribute to add keys.
One final alternative is to use the `configSource` element attribute to use the section in one of the assemblies config files.
Hope this helps.
Problem
If an assembly contains an app.config file, `ConfigurationManager` will load it as long as it is in the same directory as the NUnit project that is executing through NUnit-Gui. To illustrate consider the following folder structure. ``` + TestFolder testProject.nunit + AssemblyAFolder assemblyA.dll assemblyA.dll.config + AssemblyBFolder assemblyB.dll assemblyB.dll.config ``` Both `AssemblyA` and `AssemblyB` exercise code that calls into `ConfigurationManager`. If I run these test assemblies independently in NUnit-Gui, `ConfigurationManager` will correctly resolve the local configuration files. However, if I load `testProject.nunit` into NUnit-Gui (which contains references to both `AssemblyA` and `AssemblyB`), `ConfigurationManager` looks for the configuration file in `TestFolder` regardless of which assembly is currently executing. Is there a way to direct NUnit to reload the application configuration to the one present in the current assembly's directory? Here are the contents of `testProject.nunit`: ``` <NUnitProject> <Settings activeconfig="Debug" /> <Config name="Debug" binpathtype="Auto"> <assembly path="AssemblyAFolder\assemblyA.dll" /> <assembly path="AssemblyBFolder\assemblyB.dll" /> </Config> </NUnitProject> ```
