How to run all tests in a particular package with Maven?

I can find in the Maven docs where it shows how to run:

1. A single test
2. All tests in a single test class
3. All tests in classes matching a particular pattern

But how to run all the tests in a package? Is this possible?

I would prefer solutions that don't require modifying the pom.xml or code.

You could use a pattern as well, for example

 mvn '-Dtest=de.mypackage.*Test' test

runs all tests in classes from package de.mypackage ending on *Test.

Since this became the accepted answer, here's some further information:

• Maven uses the Maven Surefire plugin to execute tests.

• The syntax used above (qualified package name) requires Surefire version 2.19.1 or higher! Earlier versions require the use of path expressions, for example

    mvn -Dtest="de/mypackage/*Test" test
  

• I'm using quotes (` or ") to prevent the shell from performing pathname expansion, Maven doesn't require any quotes.

• A single test method can be exuted using the following syntax

    mvn -Dtest=MyUnitTest#testMethod test
  

• All tests from subpackages may be includes as well, in order to execute all tests in or beneath package de.mypackage.sub execute:

    mvn -Dtest="de/mypackage/sub/**" test
  

or with Surefire 2.19.1 or higher

    mvn -Dtest="de.mypackage.sub.**" test

There are further possibilities like using regular expressions, see the official documentation of running a single test.

AFAIK there are no command line parameter for surefire:test to run tests in a specific package.

I use a configuration variable to achieve the same effect. A fragment of my pom.xml:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.7.2</version>
            <configuration>
                <includes>
                    <include>**/${testGroup}/*Test.java</include>
                </includes>
            </configuration>
        </plugin>
    </plugins>
</build>

Now if I want to run tests in a package named "com.example", I use the following command:

mvn test -DtestGroup=com/example

You can take reference from the following scenarios:

(1) Skip all test execution during maven build

mvn package -DskipTests

(2) Execute All test cases

mvn test

(3) Execute specific test group

mvn test -DincludeGroups=TestGroup1,TestGroup2

(4) Exclude specific test group during execution

mvn test -DexcludeGroups=TestGroup3,TestGroup4

(5) Execute specific package testcases

mvn test -Dtest="test.java.com.service.map.**"

(6) Execute specific test

mvn test -Dtest=Test1,Test2

I hope it will be more helpful to you with a different combination of execution.

mvn test -Dtest=com.myrootpackage.myfirstlevelpackage.*

...and if you want to include all sub packages:

mvn test -Dtest=com.myrootpackage.myfirstlevelpackage.**.*

The pom.xml version of O Badr's answer:

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.20.1</version>
                <configuration>
                    <includes>
                 <!-- includes all tests, but not in subpackages -->
                        <include>**/package1/*</include>   
                 <!-- includes all tests, AND in subpackages -->
                        <include>**/package2/**</include>
                    </includes>
                </configuration>
            </plugin>

        </plugins>
    </build>

Had the same problem (how to run all tests in a particular package) and tried many ways, two commands that worked were:

mvn -Dtest=com.package.my.package.** test

mvn -Dtest=com.package.my.package.**.* test

It may not be the best answer, but you could run a single TestSuite (which is a Test) which includes all the test you want in one package.

It can also be done by

mvn clean test -Dtest="**/service/**/*.java"

eg: I am in my /home/repository and I want to run tests on /home/repository/service folder only

Here service folder is inside my current folder.

You can mention packages in your pom.xml through Surefire-plugin

<plugin>
			<groupId>org.apache.maven.plugins</groupId>
			<artifactId>maven-surefire-plugin</artifactId>
			<version>2.19.1</version>
			<configuration>
				<includes>
					<include>com.mycom.mydep.mypak.*, com.mycom.mydep.mypak2.*</include>
				</includes>
			</configuration>
		</plugin>

Please note that JUnit version should be greater than 4.8. and version of surefire should be 2.19.1 Find more details here
