对于用Powermock编写的测试用例，sonar中单元测试覆盖率统计不正确的问题

用PowerMock写的单元测试用例，sonar中覆盖率显示问题

sonar中没有覆盖率的显示问题

sonar中覆盖率显示不正确

sonar中单元测试用例个数不正确问题

sonar中没有覆盖率的显示问题

pom文件中jacoco-maven-plugin配置不正确，做了如下配置，sonar中有了覆盖率的显示

<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.9</version>
<executions>
<execution>

sonar中覆盖率显示不正确

sonar中覆盖率的统计为0.0%1

PowerMock的版本从1.6.3改为1.6.6,覆盖率从0.0%变为有正常数据

sonar中统计的单元测试个数不正确

单元测试用例中多了很多名为setUp和tearDown的测试用例，按照正常的来说，这个函数不应包含在测试用例里面，报错如下：

Error Message
The class xx.xx.xx.xx.xx not prepared for test. To prepare this class, add class to the '@PrepareForTest' annotation. In case if you don't use this annotation, add the annotation on class or  method level.

Stacktrace
org.powermock.api.mockito.ClassNotPreparedException:
The class xx.xx.xx.xx.xx not prepared for test.
To prepare this class, add class to the '@PrepareForTest' annotation.
In case if you don't use this annotation, add the annotation on class or  method level.

最后在@PrepareForTest()中添加了这个类之后，单元测试个数统计正确

@Test (groups = {"UT"})
@PrepareForTest({ClassName1.class,ClassName2.class})
@PowerMockIgnore({""})
