body: <p>How to configure JUnit 5 for Android unit testing?
  I tried:</p>
  
  <pre><code>testCompile("org.junit.jupiter:junit-jupiter-api:5.0.0")
  </code></pre>
  
  <p>But it doesn't work, when I run previous the simplest unit test:</p>
  
  <pre><code>@Test
  public void addition_isCorrect() throws Exception {
      assertEquals(4, 2 + 2);
  }
  </code></pre>
  
  <p>I get error:</p>
  
  <pre><code>Exception in thread "main" java.lang.NoSuchMethodError: org.junit.platform.commons.util.ReflectionUtils.getDefaultClassLoader()Ljava/lang/ClassLoader;
