title: JUnit + Derby + Spring: drop in-memory db after every test
body: <p>In my unit tests I autowired some DataSources, which use URLs like</p>
  
  <pre><code>jdbc:derby:memory:mydb;create=true
  </code></pre>
  
  <p>to create an in-memory DBs.</p>
  
  <p>To drop an in-memory Derby db you have to connect with:</p>
  
  <pre><code>jdbc:derby:memory:mydb;drop=true
  </code></pre>
  
  <p>I would like this to happen after every test and start with a fresh db. How can I do this using Spring?</p>
