Support before_script

[SCdF]

I have this in my .travis.yml:

before_script:
  - npm install grunt-cli -g

script:
  - grunt ci

But when I run trevor I get:

 ✖ 5.6:
 container_linux.go:247: starting container process caused "exec: \"grunt\": executable file not found in $PATH"
 docker: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: \"grunt\": executable file not found in $PATH".

It looks like it's not executing before_script steps?

No, Trevor currently ignores before_script. Renaming this issue to a feature request.
