The tests in CoinChangerKata repo are failing. We could always simply find the broken test,
fix it and apply a commit, but that would still leave us with a whole history of broken commits.
In order to fix our history too, apply git bisect to the repository and find the first broken
commit. Once you have found that commit, use git rebase in interactive mode to fix it and make
sure that all commits now pass.
Remember that to ease the search, you can give bisect a specific command with which to discern broken commits. For a broken test, most of the cases, a command that runs the test suite is enough.
For bisect:
$ git bisect start
$ git bisect good <commit>
$ git bisect bad <commit>
$ git bisect run <command>
For rebase:
$ git rebase -i <commit>
$ git rebase --continue
$ git rebase --abort
For ruby:
$ rspec # Runs the tests
$ ruby <file_name> # Runs the script
