對於用Powermock編寫的測試用例，sonar中單元測試覆蓋率統計不正確的問題

用PowerMock寫的單元測試用例，sonar中覆蓋率顯示問題

• sonar中沒有覆蓋率的顯示問題
• sonar中覆蓋率顯示不正確
• sonar中單元測試用例個數不正確問題

sonar中沒有覆蓋率的顯示問題

• pom文件中jacoco-maven-plugin配置不正確，做了如下配置，sonar中有了覆蓋率的顯示

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

                  <execution>
                      <id>default-check</id>
                      <goals>
                          <goal>check</goal>
                      </goals>
                      <configuration>
                          <rules>
                              <rule>
                                  <element>BUNDLE</element>

                                          <value>COVEREDRATIO</value>
                                          <minimum>0.0</minimum>
                                      </limit>
                                  </limits>
                              </rule>
                          </rules>
                      </configuration>
                  </execution>
              </executions>
          </plugin>
  

sonar中覆蓋率顯示不正確

• sonar中覆蓋率的統計爲0.0%1

PowerMock的版本從1.6.3改爲1.6.6,覆蓋率從0.0%變爲有正常數據

sonar中統計的單元測試個數不正確

單元測試用例中多了很多名爲setUp和tearDown的測試用例，按照正常的來說，這個函數不應包含在測試用例裏面，報錯如下：

    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. 

最後在@PrepareForTest()中添加了這個類之後，單元測試個數統計正確

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