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

}
@Test
