Rspec failing with Untouched resources

Question

My recipe installs the dynatrace module and enables it:

include_recipe 'dynatrace::wsagent_package'

apache2_module 'dtagent_module' do
  module_name 'dtagent_module'
  filepath node['dynatrace']['apache_wsagent']['linux']['agent_path']
  action [:enable]
end

My spec file contains the following:

  it 'creates /opt/dynatrace/agent/lib64/libdtagent.so file' do
    expect(chef_run).to render_file('/opt/dynatrace/agent/lib64/libdtagent.so')
  end

When I run Rspec it fails with the following error:

$ rspec -f d ./spec/unit/recipes/apache_spec.rb[1:4]

Run options: `include {:ids=>{"./spec/unit/recipes/apache_spec.rb"=>["1:4"]}}`

Need some help in identifying the issue causing my spec failure.

From your description, the issue isn't it failing due to untouched resources.

Your chefspec run has failed as no resource in the chef run creates the file /opt/dynatrace/agent/lib64/libdtagent.so

From the looks of https://github.com/Dynatrace/Dynatrace-Chef/blob/master/recipes/wsagent_package.rb , the recipe being included might create that file via the extraction of an archive/tar. As this is a side effect, it can't be directly tested using unit tests.

It seems you are writing a wrapper cookbook to glue two pieces of functionality together.

A tool such as test kitchen with serverspec might be better suited to the integration test you are writing.
