title: Override default Spring-Boot application.properties with application.properties
body: <p>Want to completely replace my application.properties with <code>application-test.properties</code> for my junit.
  <code>TestPropertySource</code> is not doing the job. Seems like it only replaces some of the common properties but i dont want that.</p>
  
  <p>Want to load <code>application-test.properties</code> not <code>application.properties</code> in my Junit \ integraction test.</p>
  
  <pre><code>@RunWith(SpringRunner.class)
  @ActiveProfiles( "test" )
  @SpringBootTest(classes = Application.class)
  @TestPropertySource(locations="classpath:application-test.properties")
  @AutoConfigureMockMvc
  </code></pre>
