title: How to test constructor of a class that has a @PostConstruct method using Spring?
body: <p>If I have a class with a @PostConstruct method, how can I test its constructor and thus its @PostConstruct method using JUnit and Spring? I can't simply use new ClassName(param, param) because then it's not using Spring -- the @PostConstruct method is not getting fired.</p>
  
  <p>Am I missing something obvious here?</p>
  
  <pre><code>public class Connection {
      private String x1;
      private String x2;
  
      public Connection(String x1, String x2) {
          this.x1 = x1;
          this.x2 = x2;
      }
  
      @PostConstruct
      public void init() {
          x1 = "arf arf arf";
      }
  
  }
  
  
  @Test
  public void test() {
      Connection c = new Connection("dog", "ruff");
      assertEquals("arf arf arf", c.getX1());
  }
  </code></pre>
  
  <p>I have something similar (though slightly more complex) than this and the @PostConstruct method does not get hit.</p>
