Incompatible with simplecov: does not find a rspec.failures file

[jmuheim]

I have installed rspec-rerun as told by the README, but it doesn't seem to work.

I've run rake which runs all tests, and they all passed. But then it seems to hang itself, only a Ctrl-C brings me back to the console. Take a look at the output, it seems to have problems finding an rspec.failures file. This should be generated automatically, right?

# some more rspec output before this...

I tried creating my own rspec.failures file but this didn't seem to do anything either.

Is this gem still supported and expected to work? Would be nice to use it, but didn't work at all for me.

It looks like it tried to rerun a set of specs that have not failed, which probably means that your RSpec didn't return the correct return code. Which version of RSpec are you running? Also try disable coverage, that might be the culprit.

Do run rake with --trace so we can see where the error came from.

The problem was caused by simplecov. I removed it, now it's working. Thanks!

removing simplecov is not an option for me, is there another workaround for this?

[dblock]

I'm reopening this since it looks like this gem is not compatible with simplecov. I'd welcome a small repro and then we can work on a fix.

My issue may have been related to simplecov-ruby/simplecov#281, I downgraded simplecov and rspec-rerun seems to be working now.
