Verifying text files with no extensions

[lbussell]

I'm trying to verify some Dockerfiles that I have generated with templates. I'm using VerifyDirectory to verify an entire Directory of these files. I have also enabled DiffPlex.

The convention for Dockerfiles is that they have no extension. I think that since Dockerfiles aren't listed as text files in TextExtensions, this prevents Verify from running scrubbing functions and showing diffs in test output.

I've tried using FileExtensions.AddTextExtension("noextension"), but that caused a System.IO error for some reason: System.IO.IOException : The process cannot access the file 'Dockerfile' because it is being used by another process. Perhaps because I'm verifying many Dockerfiles at the same time, not sure.

How can I get Verify to treat Dockerfiles as text files?

i added a new approach to doing this in v28.9
https://github.com/VerifyTests/Verify/blob/main/docs/verify-directory.md#files-with-no-extension

does this work for you?

I'll give it a try tomorrow and report back!

Works great. Thanks!
