The following is detecting errors during execution, but not reporting them properly. https://github.com/unifio/covalence/blob/master/lib/covalence/rake/rspec/envs_spec.rb The problem is that `expect(TerraformCli.terraform_plan(path, args: args)).to be true` should be `expect { TerraformCli.terraform_plan(path, args: args) }.to_not raise_error` This class was also not properly updated for changes made in the v0.6+
