To run a single test method in Maven, you need to provide the command as:

mvn test -Dtest=TestCircle#xyz test

where TestCircle is the test class name and xyz is the test method.

Wild card characters also work; both in the method name and class name.

If you re testing in a multi-module project, specify the module that the test is in with -pl <module-name>.

For integration tests use it.test=... option instead of test=...:

mvn -pl <module-name> -Dit.test=TestCircle#xyz integration-test

There is an issue with surefire 2.12. This is what happen to me changing maven-surefire-plugin from 2.12 to 2.11:

1. mvn test -Dtest=DesignRulesTest

   Result:
   [ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12:test (default-test) on project pmd: No tests were executed!

2. mvn test -Dtest=DesignRulesTest

   Result: [INFO] --- maven-surefire-plugin:2.11:test (default-test) @ pmd --- ... Running net.sourceforge.pmd.lang.java.rule.design.DesignRulesTest Tests run: 5, Failures: 0, Errors: 0, Skipped: 4, Time elapsed: 4.009 sec

Run a single test method from a test class.

mvn test -Dtest=Test1#methodname

Other related use-cases

• mvn test // Run all the unit test classes

• mvn test -Dtest=Test1 // Run a single test class

• mvn test -Dtest=Test1,Test2 // Run multiple test classes

• mvn test -Dtest=Test1#testFoo* // Run all test methods that match pattern testFoo* from a test class.

• mvn test -Dtest=Test1#testFoo*+testBar* // Run all test methods match pattern testFoo* and testBar* from a test class.

What I do with my TestNG, (sorry, JUnit doesn t support this) test cases is I can assign a group to the test I want to run

@Test(groups="broken")

And then simply run mvn -Dgroups=broken .

Running a set of methods in a Single Test Class With version 2.7.3, you can run only n tests in a single Test Class.

NOTE : it s supported for junit 4.x and TestNG.

You must use the following syntax

mvn -Dtest=TestCircle#mytest test

You can use patterns too

mvn -Dtest=TestCircle#test* test

As of surefire 2.12.1, you can select multiple methods (JUnit4X only at this time, patches welcome)

mvn -Dtest=TestCircle#testOne+testTwo test

Check this link about single tests

This command works !! mvn "-DTest=JoinTeamTestCases#validateJoinTeam" test Note that "-DTest" starts with UPPER CASE T .

You can run specific test class(es) and method(s) using the following syntax:

1. full package : mvn test -Dtest="com.oracle.tests.**"

2. all method in a class : mvn test -Dtest=CLASS_NAME1

3. single method from single class :mvn test -Dtest=CLASS_NAME1#METHOD_NAME1

4. multiple method from multiple class : mvn test -Dtest=CLASS_NAME1#METHOD_NAME1,CLASS_NAME2#METHOD_NAME2

First you need to clean your maven project

mvn clean

then you can run specific file and function using

mvn test -Dtest=testClassName#testCaseName

I tried several solutions provided in this thread, however they were not working for module which depends on a different one. In that case I had to run mvn from the root-module with additional parameters: -am (--also-make), which tells maven to built modules which your test module depends on and -DfailIfNoTests=false, otherwise "No tests were executed!" error appears.

mvn test -pl B -Dtest=MyTestClass#myTest -am -DfailIfNoTests=false

pom.xml section in root:

<modules>
    <module>A</module>
    <module>B</module>
<modules>

B depends on A.

The test parameter mentioned by tobrien allows you to specify a method using a # before the method name. This should work for JUnit and TestNG. I ve never tried it, just read it on the Surefire Plugin page:

Specify this parameter to run individual tests by file name, overriding the includes/excludes parameters. Each pattern you specify here will be used to create an include pattern formatted like **/${test}.java, so you can just type "-Dtest=MyTest" to run a single test called "foo/MyTest.java". This parameter overrides the includes/excludes parameters, and the TestNG suiteXmlFiles parameter. since 2.7.3 You can execute a limited number of method in the test with adding #myMethod or #my*ethod. Si type "-Dtest=MyTest#myMethod" supported for junit 4.x and testNg

New versions of JUnit contains the Categories runner: http://kentbeck.github.com/junit/doc/ReleaseNotes4.8.html

But releasing procedure of JUnit is not maven based, so maven users have to put it manually to their repositories.

As of surefire plugin version 2.22.1 (possibly earlier) you can run single test using testnames property when using testng.xml

Given a following testng.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite">
    <test name="all-tests">
        <classes>
            <class name="server.Atest"/>
            <class name="server.Btest"/>
            <class name="server.Ctest"/>
        </classes>
    </test>
    <test name="run-A-test">
        <classes>
            <class name="server.Atest"/>
        </classes>
    </test>
    <test name="run-B-test">
        <classes>
            <class name="server.Btest"/>
        </classes>
    </test>
    <test name="run-C-test">
        <classes>
            <class name="server.Ctest"/>
        </classes>
    </test>
</suite> 

with the pom.xml

<?xml version="1.0" encoding="UTF-8"?>

From command line

mvn clean test -DselectedTests=run-B-test

You need to specify the JUnit test class and its method to be executed.

mvn test -Dtest=com.mycompany.AppTest#testMethod
