Not able to run a category in Junit4 tests

Question

Have a test method annotated with category:

public interface BVT {} //is placed in package net.test.categories, file name BVT.java

public class TestClass{
    @Test
    @Category(BVT.class)
    public void someTest(){
        System.out.println("smoke");
    } }

I use Junit 4.12 and surefire 3.0.0-M3

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
</dependency>

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M3</version>
    <configuration>
        <forkCount>${threadCount}</forkCount>
        <reuseForks>false</reuseForks>
        <skip>false</skip>
        <groups>${testGroup}</groups>
    </configuration>
</plugin>

If I try to run test from BVT category

 mvn clean test -DtestGroup="net.test.categories.BVT"

I get

[INFO] Results:
[INFO]
[INFO] Tests run: 0, Failures: 0, Errors: 0, Skipped: 0

Have no ideas why the test was not run/skipped... Using of created in pom profile didn't help - it just runs all the tests. Adding this runner dependency also doesn't help:

<dependencies>
    <dependency>
        <groupId>org.apache.maven.surefire</groupId>
        <artifactId>surefire-junit47</artifactId>
        <version>3.0.0-M3</version>
    </dependency>
</dependencies>

Creating a Suite runs the needed test but I don't want to list all required classes in this suite class, just want to run a certain group from command line

Answer 1

Didn't find reason, but adding include section in surefire configuration solved the issue.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M3</version>
    <configuration>
        <forkCount>${threadCount}</forkCount>
        <reuseForks>false</reuseForks>
        <skip>false</skip>
        <groups>${testGroup}</groups>
        <includes>
            <include>*</include>
        </includes>
    </configuration>
</plugin>
