All jUnit test cases are not running for Maven project using PowerMock with easymock, Surefire - maven

Question

In a Maven Project I am using PowerMock-easymock to run jUnit test cases. but while doing "mvn clean install" , I am getting below output..
T E S T S
Running TestSuite
Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.621 sec
Results :
Tests run: 2, Failures: 0, Errors: 0, Skipped: 0
But I have many other test cases.
Here is a part of pom.xml
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.8.2</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.easymock</groupId>
<artifactId>easymock</artifactId>
<version>3.1</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-easymock-release-full</artifactId>
<version>1.4.12</version>
<type>pom</type>
</dependency>
If I remove, PowerMock dependency and do "mvn clean install" , all test cases are running fine. But I have to use PowerMock. How to solve this issue?

Answer 1

I guess that some of your test cases are not running, did you try this
Use mvn surefire plugin, and include test cases in that.
ensure dependancy of powermock-module-junit4.

Answer 2

I had the same problem, and it took me a while to figure out. My setup was pulling in an older version of jboss.javassist, which oddly was preventing the PowerMockRunner from working at all.
It's worth noting that I also have a mixed JUnit / TestNG environment. I previously tried the solution of adding multiple surefire providers, and that didn't work either (using surefire 2.14.1). After upgrading to surefire 2.17, both my JUnit and TestNG tests started running without needing to declare any surefire providers. In fact, the JUnit provider threw an error for me, because I'm using groups. Apparently the TestNG provider allows free-form text (e.g. "integration") while the JUnit provider expects a classpath (e.g. "com.example.UnitTests").
Here's my plugin section...
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.17</version>
<configuration>
<groups>spring, unit, integration</groups>
<systemPropertyVariables>
<java.awt.headless>true</java.awt.headless>
<org.apache.activemq.default.directory.prefix>target/test/</org.apache.activemq.default.directory.prefix>
<log4j.configuration>file:${project.basedir}/src/test/resources/log4j.properties</log4j.configuration>
</systemPropertyVariables>
<argLine>${surefire.args}</argLine>
</configuration>
</plugin>
... and the relevant testing deps ...
<dependency>
<groupId>org.mockito</groupId>
<artifactId>mockito-all</artifactId>
<version>1.9.5</version>
<scope>test</scope>
</dependency>

As per Dipak,
Solution 1:
Add below code in pom.xml
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.13</version>
<dependencies>
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-junit47</artifactId>
<version>2.13</version>
</dependency>
</dependencies>
</plugin>
For Correct ArtifactId in dependency , you can see this link if you are using jUnit.
Then do "mvn clean install"
Solution 2:
Add below code in pom.xml
<properties>
<powermock.version>1.5</powermock.version>
</properties>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-module-junit4</artifactId>
<version>${powermock.version}</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock</groupId>
<artifactId>powermock-api-easymock</artifactId>
<version>${powermock.version}</version>
<scope>test</scope>
</dependency>

Answer 4

I had a situation recently where PowerMock tests were run, but not included in the surefire coverage report. We found that the problem had to do with instrumentation.
I'll note that most of our tests run with TestNG. In general, we only use JUnit when we need to leverage PowerMock.
Here is the POM snippet:
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.18.1</version>
<configuration>
<systemPropertyVariables>
<org.apache.activemq.default.directory.prefix>target/test/</org.apache.activemq.default.directory.prefix>
<log4j.configuration>file:${project.basedir}/src/test/resources/log4j.properties</log4j.configuration>
<jacoco-agent.destfile>${project.basedir}/target/jacoco.exec</jacoco-agent.destfile>
</systemPropertyVariables>
<argLine>-Xmx512m -XX:MaxPermSize=256m -Djava.awt.headless=true</argLine>
</configuration>
</plugin>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.5.201505241946</version>
<executions>
<execution>
<id>instrument</id>
<phase>process-classes</phase>
<goals>
<goal>instrument</goal>
</goals>
</execution>
<execution>
<id>restore</id>
<phase>test</phase>
<goals>
<goal>restore-instrumented-classes</goal>
<goal>report</goal>
</goals>
</execution>
</executions>
</plugin>
The <systemPropertyVariables> are probably not relevant to the fix.
Also, note that JaCoCo's documentation warns against using this type of configuration unless you find it necessary.
http://www.eclemma.org/jacoco/trunk/doc/instrument-mojo.html
Warning: The preferred way for code coverage analysis with JaCoCo is
on-the-fly instrumentation. Offline instrumentation has several
drawbacks and should only be used if a specific scenario explicitly
requires this mode. Please consult documentation about offline
instrumentation before using this mode.
