  <p>I have read laravel 5.5 documentation for unittest. It's said that we just need to execute phpunit {as shown in <a href="https://laravel.com/docs/5.5/testing" rel="noreferrer">https://laravel.com/docs/5.5/testing</a>}
  Then I tried this :
  <a href="https://stackoverflow.com/questions/26095051/how-to-run-single-test-method-with-phpunit">How to run single test method with phpunit?</a></p>
  
  <pre><code>phpunit --filter testBasicTest tests\Unit\ExampleTest
  </code></pre>
  
  <p>As shown below :

  <p>BUt it's said that 'cannot open the file'. Then I Tried 
  phpunit ExampleTest, but still cannot open the file. So what's wrong here...?
  Thanks in advance</p>
  
  <p>Note :
  Here's my phpunit.xml :
