title: sbt test-only specific test
body: <p>I have several tests distributed over several classes.</p>
  
  <p>I would like to run only the first test from the first class:</p>
  
  <p>The class is:</p>
  
  <pre><code>class Step1_PrimarySpec 
  </code></pre>
  
  <p>The test is:</p>
  
  <pre><code>  test("case1: Primary (in isolation) should properly register itself to the provided Arbiter")
  </code></pre>
  
  <p>I tried:</p>
  
  <pre><code>sbt test-only Step1_PrimarySpec
  </code></pre>
  
  <p>and:</p>
  
  <pre><code>sbt test-only Step1_PrimarySpec 1
  </code></pre>
  
  <p>and:</p>
  
  <pre><code> sbt test-only "*Step1_PrimarySpec 1"
  </code></pre>
  
  <p>and:</p>
  
  <pre><code> sbt test-only "*Step1_PrimarySpec"
  </code></pre>
  
  <p>However, all of these commands ran the entire test suite.</p>
  
  <p>So how can I run only that specific test?</p>
