我正在使用JUnit和Powermockito模拟。 我必须使用maven或ant进行CLI环境。
emma version: ema-2.0.5312
powermock version: powermock-mockito-1.5.1-full
junit version: junit-4.9
当我通过以下命令运行junit时,一切正常:
java org.junit.runner.JUnitCore some.package.ClassTest
然而,当我使用emma检查代码覆盖率时:
java emmarun -cp $CLASSPATH -report txt org.junit.runner.JUnitCore some.package.ClassTest
我收到以下错误:
1) initializationError(some.pakage.ClassTest)
java.lang.ClassCastException: org.powermock.modules.junit4.PowerMockRunner cannot be cast to org.junit.runner.Runner
不使用powermock的其他测试类工作正常。 有没有人对此提出一些建议?提前谢谢。

使用powermock时,您无法使用Emma找到覆盖范围

由于Eclemma与MockitoJUnitRunner一起使用,因此您可以使用MockitoJunitRunner并指定使用PowerMock的规则。
类似这样的东西:
@RunWith(MockitoJUnitRunner.class) // This supports Eclemma Plugin. Powermock doesn't.
@PrepareForTest({/* StaticClasses for Powermock here */})
public class ClassTest {
// These two statements; the static block and @Rule make sure Powermock works along with Mockito!!
static {
PowerMockAgent.initializeIfNeeded();
}
@Rule
public PowerMockRule powerMockRule = new PowerMockRule();
@Mock // To mock dependent class
private MockClass mock;
@InjectMocks //To Inject all mocks in this class
private ClassUnderTest classObject;
//Rest of the code here.
}
需要依赖项:
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-api-mockito</artifactId>
<version>1.6.2</version>
<scope>test</scope>
</dependency>
<dependency>

此外,您还需要将其添加到Coverage As-> Coverage Configurations-> Arguments下的配置中。
要使其与Jacoco一起使用,请在pom.xml中使用以下语句。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.18.1</version>
<configuration>
<argLine>${argLine} -noverify -javaagent:${settings.localRepository}/org/powermock/powermock-module-javaagent/1.6.2/powermock-module-javaagent-1.6.2.jar</argLine>
</configuration>
</plugin>
