Description Alan McGovern 2012-06-22 06:32:13 UTC
1) Compiled monodevelop with --enable-test passed to configure.
2) Build and run any of the unit test assemblies
3) This works perfectly.

4) Open the cecil solution in main/external/cecil
5) Build and attempt to run any of it's tests

It fails with error [0].

This is caused by our external test runner attempting to load the test assemblies in the same appdomain as itself. These particular test assemblies are compiled against NUnit, which is bundled in cecils source code. We need to be able to support this kind of construct with our test runner. NUnit itself already supports this so we just need to fix our ExternalTestRunner to not require loading these assemblies in its own appdomain. Alternatively we could pull in the NUnit source code and compile it directly into our ExternalTestRunner so that it has no dependency on any external assemblies.

Seems to work in 6.0
