Thanks for looking into the test failure, we can definitely fix that.

It looks like the testrun on jenkins also found another problem with the formula. Does this make sense? It's not clear to me why the install method should be at the top-level and not in the class body (having looked at a few other formulae).

```
==> brew audit cf							 FAILED
Error: 1 problems in 1 formulae
cf:
 * Define method "install" in the class body, not at the top-level
```
