title: How to setup environment variable via Junit?
body: <p>I am testing a delegate class with Junit.
  When i right click on Run Configurations and put the key-value pair in Environment tab, it works fine.</p>
  
  <p>I unsuccessfully tried to set it from a static block as well as @Before method.
  Can you help?</p>
  
  <pre><code>public MyClass{
  public void myMethod(){
  String tmp = configProps.getProperty("auto_commit_location");
  String commitScriptLocation = System.getenv(tmp);
  System.out.println(commitScriptLocation); --- This returns null
   }
  }
  
  Junit Test:
  
  public class AutoCommitControlDelegateTest {
  
      static {
          System.setProperty("auto_commit_location", "/tmp/");
      }
  
      @Autowired
      private *******
      //calls to my methods
  </code></pre>
