How do I get my Maven Integration tests to run

Question

I have a maven2 multi-module project and in each of my child modules I have JUnit tests that are named Test java and Integration java for unit tests and integration tests respectively   When I execute     mvn test   all of the JUnit tests  Test java within the child modules are executed    When I execute    mvn test -Dtest     Integration    none of the Integration java tests get execute within the child modules   These seem like the exact same command to me but the one with the -Dtest   Integration   does not work it displays 0 tests being run at the parent level  which there are not any tests

The Maven build lifecycle now includes the "integration-test" phase for running integration tests, which are run separately from the unit tests run during the "test" phase. It runs after "package", so if you run "mvn verify", "mvn install", or "mvn deploy", integration tests will be run along the way.

By default, integration-test runs test classes named **/IT*.java, **/*IT.java, and **/*ITCase.java, but this can be configured.

For details on how to wire this all up, see the Failsafe plugin, the Failsafe usage page (not correctly linked from the previous page as I write this), and also check out this Sonatype blog post.

You can set up Maven s Surefire to run unit tests and integration tests separately   In the standard unit test phase you run everything that does not pattern match an integration test   You then create a second test phase that runs just the integration tests   Here is an example        lt plugin gt         lt groupId gt org apache maven plugins lt  groupId gt         lt artifactId gt maven-surefire-plugin lt  artifactId gt         lt configuration gt           lt excludes gt             lt exclude gt     IntegrationTest java lt  exclude gt           lt  excludes gt         lt  configuration gt         lt executions gt           lt execution gt             lt id gt integration-test lt  id gt             lt goals gt               lt goal gt test lt  goal gt             lt  goals gt             lt phase gt integration-test lt  phase gt             lt configuration gt               lt excludes gt                 lt exclude gt none lt  exclude gt               lt  excludes gt               lt includes gt                 lt include gt     IntegrationTest java lt  include gt               lt  includes gt             lt  configuration gt           lt  execution gt         lt  executions gt       lt  plugin gt

Another way of running integration tests with Maven is to make use of the profile feature        lt build gt       lt plugins gt           lt plugin gt               lt groupId gt org apache maven plugins lt  groupId gt               lt artifactId gt maven-surefire-plugin lt  artifactId gt               lt configuration gt                   lt includes gt                       lt include gt     Test java lt  include gt                   lt  includes gt                   lt excludes gt                       lt exclude gt     IntegrationTest java lt  exclude gt                   lt  excludes gt               lt  configuration gt           lt  plugin gt       lt  plugins gt   lt  build gt    lt profiles gt       lt profile gt           lt id gt integration-tests lt  id gt           lt build gt               lt plugins gt                   lt plugin gt                       lt groupId gt org apache maven plugins lt  groupId gt                       lt artifactId gt maven-surefire-plugin lt  artifactId gt                       lt configuration gt                           lt includes gt                               lt include gt     IntegrationTest java lt  include gt                           lt  includes gt                           lt excludes gt                               lt exclude gt     StagingIntegrationTest java lt  exclude gt                           lt  excludes gt                       lt  configuration gt                   lt  plugin gt               lt  plugins gt           lt  build gt       lt  profile gt   lt  profiles gt        Running  mvn clean install  will run the default build  As specified above integration tests will be ignored  Running  mvn clean install -P integration-tests  will include the integration tests  I also ignore my staging integration tests   Furthermore  I have a CI server that runs my integration tests every night and for that I issue the command  mvn test -P integration-tests

I have done EXACTLY what you want to do and it works great   Unit tests   Tests  always run  and   IntegrationTests  only run when you do a mvn verify or mvn install   Here it the snippet from my POM   serg10 almost had it right    but not quite      lt plugin gt       lt  -- Separates the unit tests from the integration tests  -- gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-surefire-plugin lt  artifactId gt       lt configuration gt          lt  -- Skip the default running of this plug-in  or everything is run twice   see below  -- gt          lt skip gt true lt  skip gt          lt  -- Show 100  of the lines from the stack trace  doesn t work  -- gt          lt trimStackTrace gt false lt  trimStackTrace gt       lt  configuration gt       lt executions gt          lt execution gt             lt id gt unit-tests lt  id gt             lt phase gt test lt  phase gt             lt goals gt                lt goal gt test lt  goal gt             lt  goals gt             lt configuration gt                   lt  -- Never skip running the tests when the test phase is invoked -- gt                   lt skip gt false lt  skip gt                lt includes gt                      lt  -- Include unit tests within integration-test phase  -- gt                   lt include gt     Tests java lt  include gt                lt  includes gt                lt excludes gt                  lt  -- Exclude integration tests within  unit  test phase  -- gt                   lt exclude gt     IntegrationTests java lt  exclude gt               lt  excludes gt             lt  configuration gt          lt  execution gt          lt execution gt             lt id gt integration-tests lt  id gt             lt phase gt integration-test lt  phase gt             lt goals gt                lt goal gt test lt  goal gt             lt  goals gt             lt configuration gt               lt  -- Never skip running the tests when the integration-test phase is invoked -- gt                lt skip gt false lt  skip gt                lt includes gt                  lt  -- Include integration tests within integration-test phase  -- gt                  lt include gt     IntegrationTests java lt  include gt                lt  includes gt             lt  configuration gt          lt  execution gt       lt  executions gt     lt  plugin gt    Good luck

By default  Maven only runs tests that have Test somewhere in the class name  Rename to IntegrationTest and it ll probably work  Alternatively you can change the Maven config to include that file but it s probably easier and better just to name your tests SomethingTest  From Inclusions and Exclusions of Tests   By default  the Surefire Plugin will automatically include all test classes with the following wildcard patterns        Test   java - includes all of its subdirectory and all java filenames that start with  quot Test quot          Test java - includes all of its subdirectory and all java filenames that end with  quot Test quot          TestCase java - includes all of its subdirectory and all java filenames that end with  quot TestCase quot    If the test classes does not go with the naming convention  then configure Surefire Plugin and specify the tests you want to include

You should use maven surefire plugin to run unit tests and maven failsafe plugin to run integration tests  Please follow below if you wish to toggle the execution of these tests using flags  Maven Configuration          lt plugin gt               lt groupId gt org apache maven plugins lt  groupId gt               lt artifactId gt maven-surefire-plugin lt  artifactId gt               lt configuration gt                   lt skipTests gt   skipUnitTests  lt  skipTests gt               lt  configuration gt           lt  plugin gt            lt plugin gt               lt groupId gt org apache maven plugins lt  groupId gt               lt artifactId gt maven-failsafe-plugin lt  artifactId gt               lt configuration gt                   lt includes gt                       lt include gt     IT java lt  include gt                   lt  includes gt                   lt skipTests gt   skipIntegrationTests  lt  skipTests gt               lt  configuration gt               lt executions gt                   lt execution gt                       lt goals gt                           lt goal gt integration-test lt  goal gt                           lt goal gt verify lt  goal gt                       lt  goals gt                   lt  execution gt               lt  executions gt           lt  plugin gt            lt properties gt               lt skipTests gt false lt  skipTests gt               lt skipUnitTests gt   skipTests  lt  skipUnitTests gt               lt skipIntegrationTests gt   skipTests  lt  skipIntegrationTests gt           lt  properties gt   So  tests will be skipped or switched according to below flag rules  Tests can be skipped by below flags   -DskipTests skips both unit and integration tests -DskipUnitTests skips unit tests but executes integration tests -DskipIntegrationTests skips integration tests but executes unit tests  Running Tests Run below to execute only Unit Tests mvn clean test  You can execute below command to run the tests  both unit and integration  mvn clean verify  In order to run only Integration Tests  follow mvn failsafe integration-test  Or skip unit tests mvn clean install -DskipUnitTests  Also  in order to skip integration tests during mvn install  follow mvn clean install -DskipIntegrationTests  You can skip all tests using mvn clean install -DskipTests

You can split them very easily using JUnit categories and Maven  This is shown very  very briefly below by splitting unit and integration tests   Define A Marker Interface The first step in grouping a test using categories is to create a marker interface    This interface will be used to mark all of the tests that you want to be run as integration tests     public interface IntegrationTest      Mark your test classes  Add the category annotation to the top of your test class   It takes the name of your new interface   import org junit experimental categories Category    Category IntegrationTest class  public class ExampleIntegrationTest        Test     public void longRunningServiceTest   throws Exception              Configure Maven Unit Tests The beauty of this solution is that nothing really changes for the unit test side of things  We simply add some configuration to the maven surefire plugin to make it to ignore any integration tests    lt plugin gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-surefire-plugin lt  artifactId gt       lt version gt 2 11 lt  version gt       lt configuration gt           lt includes gt               lt include gt      class lt  include gt           lt  includes gt           lt excludedGroups gt              com test annotation type IntegrationTest          lt  excludedGroups gt       lt  configuration gt   lt  plugin gt    When you do a mvn clean test  only your unmarked unit tests will run   Configure Maven Integration Tests Again the configuration for this is very simple  We use the standard failsafe plugin and configure it to only run the integration tests    lt plugin gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-failsafe-plugin lt  artifactId gt       lt version gt 2 19 1 lt  version gt       lt configuration gt           lt includes gt               lt include gt      class lt  include gt           lt  includes gt           lt groups gt              com test annotation type IntegrationTest          lt  groups gt       lt  configuration gt   lt  plugin gt    The configuration uses a standard execution goal to run the failsafe plugin during the integration-test phase of the build   You can now do a mvn clean install  This time as well as the unit tests running   the integration tests are run during the integration-test phase

You can follow the maven documentation to run the unit tests with the build and run the integration tests separately    lt project gt       lt properties gt           lt skipTests gt true lt  skipTests gt       lt  properties gt                 lt build gt           lt plugins gt               lt plugin gt                   lt groupId gt org apache maven plugins lt  groupId gt                   lt artifactId gt maven-failsafe-plugin lt  artifactId gt                   lt version gt 2 20 1 lt  version gt                   lt configuration gt                       lt skipITs gt   skipTests  lt  skipITs gt                   lt  configuration gt               lt  plugin gt           lt  plugins gt       lt  build gt             lt  project gt    This will allow you to run with all integration tests disabled by default  To run them  you use this command   mvn install -DskipTests false
