Dynamic injection in metadata object

[mickaeltavares]

Hi !

I am trying to add some runtime data (like how much time does my test setup takes?) inside the metadata object. After some investigation, I figured I could access the metadata object inside each test, but I cannot find a way to write in it.

it 'logs metadata object' do
  puts metadata # {}
end

Using tags works fine, but they are not dynamic:

it 'logs metadata object with tags', hello: 'you' do
  puts metadata # {:hello=>"you"}
end

Adding to metadata won't work:

it 'add to metadata object does not work', hello: 'you' do
  metadata[:testing_something] = 'This will not appear'
  metadata[:setup_timer] = @setup_timer # computed between before_setup and after_setup hooks
  puts metadata # {:hello=>"you"}
end

Is there a way to inject such data in metadata?
Thanks!

I'll take a look when I get a chance.

Hi !
Thank you for your response!

I've tried to play around the limitation described above today, and I found that calling metadata was using MinispecMetadata::It#metadata, which seems immutable.
I tried uninstalling the gem to run the same test: calling metadata is using Minitest::Runnable#metadata which is mutable as expected.

Thus, I believe something in MinispecMetadata is making metadata immutable or frozen somehow. It really feels like a bug.

Hope this helps 😉

Hi @ordinaryzelig, any news on that subject 😇?

I'm sorry, I haven't had any time to look into this.
