title: @BeforeAll in superclass is not executed
body: <p>In superclass, the method annotated with <code>@BeforeClass</code> seems not to be executed </p>
  
  <pre><code>    @TestInstance(TestInstance.Lifecycle.PER_CLASS)
  open class TestBase {
  
      var status: Boolean = false
  
      @BeforeAll
      open fun setStatus() {
          status = true
      }
  }
  
  class MyAppTest : TestBase() {
  
      @Test
      fun testStatus() {
          assertTrue(status) //fails
      }
  
  }
  </code></pre>
  
  <p>Is this the desirable behaviour or am I doing something wrong?</p>
