title: ruby on rails graphql test file
body: <p>I'm learning Ruby on Rails with graphQL and following this tutorial</p>
  <p><a href="https://www.howtographql.com/graphql-ruby/3-mutations/" rel="nofollow noreferrer">https://www.howtographql.com/graphql-ruby/3-mutations/</a></p>
  <p>I'm at the last part with the unit test and I just don't know where to create the <code>create_link_test.rb</code> file. The file path in the tutorial doesn't make sense to me, idk where to find the <code>graphql-ruby</code> directory within my project. I tried running <code>rails test</code> on git bash but it returns this which I think means it didn't run the test file:</p>

  <p>I appreciate any help! Edit: I created my file in <code>app/graphql/mutations</code> to try running <code>rails test</code></p>
