Junit4 and TestNG in one project with Maven

Question

To run them together there are few options available but I have chosen using different profiles for Junit and TestNG. But now problem is with excluding and including test c

Answer 1

I didn't find any combined solution online for both Surefire and Failsafe. The POM file changes below worked for me.

• The Surefire trick is done by explicitly specifying the child plugin for both JUnit and TestNG.
• The Failsafe trick is done by defining two executions, each with an empty configuration, one for JUnit and the other for TestNG.

Both solutions are hacks that I found online. I think the link to the Surefire trick is in another answer to this question.

Answer 2

The configuration for the compiler plugin excludes the TestNG types. The configuration from the profile is merged with the default configuration, so your effective compiler configuration is:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <configuration>
    <source>1.5</source>
    <target>1.5</target>
    <testIncludes>
      <testInclude>**/tests/**.java</testInclude>
      <testInclude>**/tests/utils/**.*</testInclude>
    </testIncludes>
    <testExcludes>
      <testExclude>**/tests/**.*</testExclude>
      <testExclude>**/tests/utils/**.*</testExclude>
    </testExcludes>
  </configuration>
</plugin>

This means that your TestNG types aren't ever compiled and therefore aren't run.

If you specify the <excludes> section in the testNG profile it will override the default excludes and your TestNG types will be compiled and run. I can't remember if it will work with an empty excludes tag (i.e. <excludes/>), you may have to specify something like this to ensure the default configuration is overridden.

    <testExcludes>
      <testExclude>dummy</testExclude>
    </testExcludes>

Simplest solution is like this

<plugin>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>${surefire.version}</version>
    <dependencies>
        <dependency>
            <groupId>org.apache.maven.surefire</groupId>
            <artifactId>surefire-junit47</artifactId>
            <version>${surefire.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.maven.surefire</groupId>
            <artifactId>surefire-testng</artifactId>
            <version>${surefire.version}</version>
        </dependency>
    </dependencies>
</plugin>
