danger-spec_postfix

$ gem install danger-spec_postfix

1. Add lint to your Dangerfile (specifying what you want to check and how)

For example in order to make sure that all tests in your 'spec/' folder have required postfix '_spec' (this is the purpose plugin was initially built for) add:

```
options = {
  message: 'Tests should have `_spec` postfix',
  include_path: %r{spec/},
  match: %r{_spec.rb$}
}
spec_postfix.lint(options)
```

You can also pass `exclude_path` param in order to skip irrelevant files or directories:

```
options = {
  message: 'Tests should have `_spec` postfix',
  include_path: %r{spec/},
  match: %r{_spec.rb$}
  exclude_path: Regexp.union(%r{rails_helper.rb}, %r{rails_helper.rb}, %{spec/factories/}, %r{spec/support/})
}
spec_postfix.lint(options)
```

2. Get warnings:

```
"Tests should have `_spec` postfix: spec/models/test_without_postfix.rb"
```
