Update test suite for exercise: rna-transcription

[ErikSchierboom]

The rna-transcription exercise's test suite is automatically generated using its test generator. This test generator converts the rna-transcription's canonical data into the test suite just mentioned.

The canonical data for the rna-transcription exercise has been updated since the test suite was last generated. We should be updating the test suite to the latest version. To do this, one should:

• Run the test generator for the exercise. This is done by opening a command prompt in the generators directory and running: dotnet run -e rna-transcription.
• At this point, you should check to see what the updated test suite looks like. There are basically two options: one, the test generator was compatible with the updated canonical data and the test suite was updated and still has the same structure. The second option is that the test generator could not process the changed canonical data, in which case the generator has to be modified. In that case, you should check out the generator docs in which the generators setup is explained in detail.
• Finally, please make sure that the example implementation passes all the tests. You can verify this by opening a command prompt in the root directory and running ./build.sh --exercise=rna-transcription or .\build.ps1 -Exercise rna-transcription, depending on your operating system.

I looked at taking this issue, but I ran into a problem running the generator. Do we expect it to work on Linux? It looks like it can't find a DLL relating to Git:

Using launch settings from /home/michael/git/mpriestman/fsharp/generators/Properties/launchSettings.json...

Any ideas? Do I need Mono installed?

OK. Found someone else had the same problem on Ubuntu. It looks like there are some native libraries for Linux, perhaps something isn't quite set up correctly with the LibGit2Sharp package. I'll investigate when I have some free time.

I haven't yet tested on Linux, although I can confirm that it works fine on macOS. Let me know if you find anything, might indeed be a bug with the LibGit2Sharp package.

I found two possibly related issues:

• System.DllNotFoundException: lib/linux/x86_64/libgit2-1196807.so on Ubuntu Linux libgit2/libgit2sharp#1585
• Build failing on Ubuntu 18.04.1 via WLS veldrid/veldrid#119

[mpriestman]

Yep, they look relevant. I'll have a dig in this evening when I get home. Thanks!
