在我们公司,我们有 90% 的代码覆盖率要求。

运行 Cobertura 报告,我只得到 88.8% 的覆盖率,并且我看到以下 switch 语句突出显示:

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;
     }
 }

它报告了80%的覆盖率。brandParamType 是以下枚举类型:

public enum BrandParamType {

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

在我的单元测试中,我使用这些值中的每一个调用 getPrefix,那么为什么我在这里没有获得 100% 的分支覆盖率呢?

我正在运行的单元测试如下:

@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);
}

运行一个非常相似的测试,我看到 100% 的覆盖率。但是,当我mvn cobertura:cobertura在代码更改后运行但没有clean. 尝试删除您的 Cobertura 状态。
