Rerun a failed spec from some shared examples

[ollieh-m]

When a spec fails that is from some shared examples, the rerun then reports 0 examples, 0 failures, so it isn't rerunning the failed spec.

Would it be possible to rerun the shared example in the context of where it failed?

I think the rerun would need to do something like this:
rspec spec/features/spec_that_includes_it_behaves_like.rb --example 'Name of specific test in the shared examples that failed'

What version of rspec are you using?

I believe this works already, but you would need to be on Rspec => 3.2

When a shared example defined in an external file fails, use the host example group (from a loaded spec file) for the re-run command to ensure the command will actually work

[ollieh-m]

I'm on Rspec 3.6.0.

The changelog specifies that the rerun will use the host example group (**from a loaded spec file**) - I currently require the files for the shared examples within each file where they are needed, rather than loading them in before all the specs. I wonder if that could be the issue?... I can reorganise my tests to check.

I reorganised my files so the shared example files are now loaded through rails_helper, and the rerun now happens successfully* - so thank you for the steer!

* all of the shared examples under the it_behaves_like group get rerun, not just the individual example that failed. This is fine, but I wonder if it would be possible for the specific failed example to be re-run using this kind of command: rspec spec/features/spec_that_includes_it_behaves_like.rb --example 'Name of specific test in the shared examples that failed'

If you test this without using rspec-rerun, what does the failure output from rspec look like?
To test, I just set up a quick spec that is using it_behaves_like with 2 tests in the shared file. One of the shared tests will always fail.

When the failure is in a shared group, the failure output should similar to:

Failed examples:

rspec ./spec/features/some_spec.rb[1:1:1] # admin user creation behaves like user creation creating a user sends setup instructions

We get the rerun argument from rspec here: https://github.com/dblock/rspec-rerun/blob/master/lib/rspec-rerun/formatter.rb#L29

Are you on version the latest version of this gem?

As always, maybe try to reproduce this in a spec in this repo @ollieh-m?
