Maven2编译我的测试，但不运行它们

Question

I have a simple Maven2 project with tests written for TestNG. When I say mvn test Maven2 compiles my test, but don't run them. I already checked this page: http://maven.apache.org/general.html#test-property-name . This is not my case.

Anybody can help?

My directory structure:

pom.xml
src
  main
    java
      com ...
  test
    java
      com ...
target
  classes <— .class files go there
  test-classes <— .class files with tests go there

This is what I see if I run mvn -X test (end of the log):

...
[INFO] Surefire report directory: <mydir>/target/surefire-reports

I have two tests in the project ( MainTest.java and FileSetTest.java ).

Answer 1

The "problem" is somehow related to the fact that you are compiling your tests using the jsr14 target mode which causes the compiler to emit JDK 1.4-compatible bytecode so I think that annotations are removed and TestNG doesn't detect anything to run.

My suggestion would be to configure the maven-compiler-plugin to use different compliance level when compiling code code from main and test as shown below:

<plugin>
  <artifactId>maven-compiler-plugin</artifactId>
  <configuration>
    <source>1.6</source>
    <target>jsr14</target>
  </configuration>
  <executions>
    <execution>
      <id>test-compile</id>
      <phase>process-test-sources</phase>
      <goals>
        <goal>testCompile</goal>
      </goals>
      <configuration>
        <source>1.6</source>
        <target>1.6</target>
      </configuration>
    </execution>
  </executions>
</plugin>

I did a quick test, it seems to work.
