Gradle Jacoco 在使用 Powermock 时不跟踪 Spock 测试的覆盖率

Question

我正在使用 Gradle Jacoco 插件来记录我们软件的测试覆盖率。该软件包含一些大量使用静态方法的遗留代码。为了模拟它们，我们想出了 Powermock 并将其集成到我们的 Spock 测试中。

到目前为止一切正常。仅的事情是 Jacoco 不跟踪使用 Powermock 的测试的测试覆盖率。普通 Spock 测试（不使用 Powermock 的测试）的测试覆盖率按预期报告。

有人知道如何 Jacoco 记录我的 Powermock 测试的覆盖率吗？

请在下面找到 Spock 测试。

@PrepareForTest([CodeCacheManager])
class SampleSpec extends Specification {

 @Rule
 PowerMockRule powerMockRule = new PowerMockRule();

 @Unroll
 void "Convert CodeIdentifier #insertvalue toString #returnvalue"() {

    given:
    def converter = new CodeIdentifierCodeInternalNameCustomConverter()

    and:
    mockStatic(CodeCacheManager.class)
    Mockito.when(CodeCacheManager.getInternalNameForCode(insertvalue)).thenReturn(returnvalue)

    when:
    String value = converter.convertTo(insertvalue, null)

    then:
    value == returnvalue

    where:
    insertvalue                      | returnvalue
    PartnerCodes.Geschlecht.mannlich | "männlich"
    null                             | "NO INTERNAL NAME"
 }
}

测试方法的实现看起来

public String convertTo (CodeIdentifier source, String destination)
{
  if (source != null)
  {
     return CodeCacheManager.getInternalNameForCode (source);
  }
  return "NO INTERNAL NAME";
}

Answer 1

PowerMock 和 Jacoco 不兼容，不能一起使用。

Answer 2

Jacoco 离线检测是解决这个问题的方法。

查看我的 gradle 构建文件

                sourcefiles {
                    fileset(dir: 'src/main/java')
                }
            }
            html(destdir: buildDir.path + '/reports/jacoco')
        }
    }
}

此处报告任务将创建项目的离线检测文件。

最后执行sonarqube任务。然后你可以看到powermocked的覆盖范围类也已经包含了。

Execution command ./gradlew report sonarqube

那就去你的sonarqube主机(localhost:9000)看看吧。
