Is there a reliable Command Line or Powershell step format to run RSpec tests on TeamCity?

Question

We are experimenting with using RSPec for our UI tests and noted that while attempting to integrate these with TeamCity we end up with environment related errors. The problem is that when we run these tests locally on the build server they run without any errors.

We are trying to execute the login test within a working directory located on the build server with a Command Line or Powershell:

cd D:\web_smoke_tests-master
gem install bundler
rake cloud:chrome 

We are returning the following error in our build log despite the environment containing all of the ruby dependencies. Note that this is a windows build server / build agent.

Answer 1

Regarding the above. This was due to the user containing the build agent not having any ruby dependencies installed and as a result "gem" or "rake" were not recognized.
