android中单元测试中的断言assert的使用与扩展

首先看一组对比，比如说我们要测试的结果是一个Linearlaout  

• AssertJ Android:

  assertThat(layout).isVisible()
      .isVertical()
      .hasChildCount(4)
      .hasShowDividers(SHOW_DIVIDERS_MIDDLE);
  

• Regular JUnit:

  assertEquals(View.VISIBLE, layout.getVisibility());
  assertEquals(VERTICAL, layout.getOrientation());
  assertEquals(4, layout.getChildCount());
  assertEquals(SHOW_DIVIDERS_MIDDLE, layout.getShowDividers());
  

• Regular AssertJ:

  assertThat(layout.getVisibility()).isEqualTo(View.VISIBLE);
  assertThat(layout.getOrientation()).isEqualTo(VERTICAL);
  assertThat(layout.getChildCount()).isEqualTo(4);
  assertThat(layout.getShowDividers()).isEqualTo(SHOW_DIVIDERS_MIDDLE);

从输出结果上看，输出结果更加直接可见。

• AssertJ Android:     Expected visibility <gone> but was <invisible>.

• Regular JUnit          Expected:<[8]> but was:<[4]>

• Regular AssertJ:     Expected: <8> but was: <4>
