  @Test
  public void foo()
  {
    // The test adds following things :
    // 1. Adds three property KVs (prop1, goA), (prop2, goB), (prop3, goA)
    // 2. Adds two options for Gogo.class in separate modules : GoA and GoB which have binding keys as 'goA' and 'goB'
    // 3. Adds three choices for Gogo.class in separate modules which correspond to the three properties
    // 4. checks via injector that first and third choice create GoA instances whereas choice second creates GoB instance
    props = new Properties();
    props.setProperty("prop1", "goA");
