Cobertura，Enums和Switch语句

在我们公司，我们的代码覆盖率要求为90％。Cobertura，Enums和Switch语句

运行的Cobertura报告，我只获得88.8％的覆盖率，和我看到下面的开关声明强调：

public TopBrandPrefix getPrefix() { 
    switch(brandParamType) { 
     case TOP12SUCHAS_AND: 
      return TopBrandPrefix.SUCHAS; 
     case TOP12COMME_ET: 
      return TopBrandPrefix.COMME; 
     case TOP12WIE_UND: 
      return TopBrandPrefix.WIE; 
     default: 
      return TopBrandPrefix.NULL; 
    } 
}

据报道80％的覆盖率。 brandParamType是以下枚举类型的：

public enum BrandParamType { 

    TOP123, 
    TOP456, 
    TOP123LINKED, 
    TOP456LINKED, 
    TOP12, 
    TOP12AND, 
    TOP12SUCHAS_AND, 
    TOP12COMME_ET, 
    TOP12WIE_UND 
}

在我的单元测试，我打电话getPrefix与这些价值观，那为什么我不及彼100％分支覆盖？是

我运行单元测试如下：

@Test 
public void testGetPrefixWithTOP123() { 
    TopBrandTouchpointParameterSource source = new TopBrandTouchpointParameterSource(urlComposer, TouchpointParameterHelper.BrandParamType.TOP123); 
    TopBrandTouchpointParameterSource.TopBrandPrefix prefix = source.getPrefix(); 
    assertEquals(TopBrandTouchpointParameterSource.TopBrandPrefix.NULL, prefix); 
} 

@Test 
public void testGetPrefixWithTOP456() { 
    TopBrandTouchpointParameterSource source = new TopBrandTouchpointParameterSource(urlComposer, TouchpointParameterHelper.BrandParamType.TOP456); 
    TopBrandTouchpointParameterSource.TopBrandPrefix prefix = source.getPrefix(); 
    assertEquals(TopBrandTouchpointParameterSource.TopBrandPrefix.NULL, prefix); 
} 

@Test 
public void testGetPrefixWithTOP123LINKED() { 
    TopBrandTouchpointParameterSource source = new TopBrandTouchpointParameterSource(urlComposer, TouchpointParameterHelper.BrandParamType.TOP123LINKED); 
    TopBrandTouchpointParameterSource.TopBrandPrefix prefix = source.getPrefix(); 
    assertEquals(TopBrandTouchpointParameterSource.TopBrandPrefix.NULL, prefix); 
} 

@Test 
public void testGetPrefixWithTOP456LINKED() { 
    TopBrandTouchpointParameterSource source = new TopBrandTouchpointParameterSource(urlComposer, TouchpointParameterHelper.BrandParamType.TOP456LINKED); 
    TopBrandTouchpointParameterSource.TopBrandPrefix prefix = source.getPrefix(); 
    assertEquals(TopBrandTouchpointParameterSource.TopBrandPrefix.NULL, prefix); 
} 

@Test 
public void testGetPrefixWithTOP12() { 
    TopBrandTouchpointParameterSource source = new TopBrandTouchpointParameterSource(urlComposer, TouchpointParameterHelper.BrandParamType.TOP12); 
    TopBrandTouchpointParameterSource.TopBrandPrefix prefix = source.getPrefix(); 
    assertEquals(TopBrandTouchpointParameterSource.TopBrandPrefix.NULL, prefix); 
} 

@Test 
public void testGetPrefixWithTOP12AND() { 
    TopBrandTouchpointParameterSource source = new TopBrandTouchpointParameterSource(urlComposer, TouchpointParameterHelper.BrandParamType.TOP12AND); 
    TopBrandTouchpointParameterSource.TopBrandPrefix prefix = source.getPrefix(); 
    assertEquals(TopBrandTouchpointParameterSource.TopBrandPrefix.NULL, prefix); 
} 

@Test 
public void testGetPrefixWithTOP12SUCH_AS() { 
    TopBrandTouchpointParameterSource source = new TopBrandTouchpointParameterSource(urlComposer, TouchpointParameterHelper.BrandParamType.TOP12SUCHAS_AND); 
    TopBrandTouchpointParameterSource.TopBrandPrefix prefix = source.getPrefix(); 
    assertEquals(TopBrandTouchpointParameterSource.TopBrandPrefix.SUCHAS, prefix); 
} 

@Test 
public void testGetPrefixWithTOP12COMME_ET() { 
    TopBrandTouchpointParameterSource source = new TopBrandTouchpointParameterSource(urlComposer, TouchpointParameterHelper.BrandParamType.TOP12COMME_ET); 
    TopBrandTouchpointParameterSource.TopBrandPrefix prefix = source.getPrefix(); 
    assertEquals(TopBrandTouchpointParameterSource.TopBrandPrefix.COMME, prefix); 
} 

@Test 
public void testGetPrefixWithTOP12WIE_UND() { 
    TopBrandTouchpointParameterSource source = new TopBrandTouchpointParameterSource(urlComposer, TouchpointParameterHelper.BrandParamType.TOP12WIE_UND); 
    TopBrandTouchpointParameterSource.TopBrandPrefix prefix = source.getPrefix(); 
    assertEquals(TopBrandTouchpointParameterSource.TopBrandPrefix.WIE, prefix); 
}

为了确保，请添加您的测试代码。 – Markus

你的单元测试是否覆盖了所有四种可能的情况，包括'default'情况？ – Jesper

单元测试使用TopBrandPrefix的每个可能的值调用此函数 – Xetius

运行一个非常相似的测试中，我看到100％的覆盖率。但是，当我在代码更改后运行mvn cobertura:cobertura，但没有clean时，我收到了部分分支报道的报告。尝试删除您的Cobertura状态。
