My E2E tests are running pretty slowly (25 minutes) as they call a bunch of services and wait for some data to be populated in the database. I want to run it concurrently. I'm using the following maven-failsafe-plugin setup:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<version>${plugin.failsave.version}</version>
<executions>
<execution>
<id>run-integration-tests</id>
<phase>integration-test</phase>
<goals>
<goal>integration-test</goal>
<goal>verify</goal>
</goals>
</execution>
</executions>
</plugin>
And my test looks something like this (more information can be provided if it is needed):
#Stepwise
#DataJpaTest
#ContextConfiguration(classes = SomeControllerITConfig)
#AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
class SomeControllerIT extends Specification {
// some variables definition
def "test1":
// some test
def "test2":
// some test
// some more tests
}
I tried to use threadCount property along with parallel or forkCount but nothing works for me. Also I tried to force the following dependency in the maven-failsafe-plugin dependencies:
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-junit47</artifactId>
<version>2.16</version>
</dependency>
Thanks in advance!
I ended up with the following issue on GitHub:
https://github.com/spockframework/spock/issues/691
Comment or whatever if you're also interested in parallel test execution in Spock.
In short, I've found a pull request with enabling parallel execution and it is even merged into one of the branches. However it is not merged into master yet. So the only way out I see for now is to write my own custom BaseSpecRunner
Looks like Spock team added support for parallel execution:
http://spockframework.org/spock/docs/2.0-M4/parallel_execution.html#parallel-execution
requires groovy: >3.0.6

Base Spock specification is:
#SpringBootTest(classes = ApplicationTestConfig.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
#TestPropertySource("/application.properties")
abstract class SpringBootTestSpecification extends Specification {
Project is building by maven 3.3.9 with failsafe-plugin:

I want to run my test in parallel mode but I want to be sure that one won't affect others (application runs with embedded DB and prepares different data for different tests).
If the embedded DB would be the same (same file / url / name) for every test, even though it probably gets truncated or recreated, parallelize the tests might not work as expected as one test might be running while another might attempt to reseed the data.
If somehow each test connects to a unique DB, my guess is that tests could be parallelized.
http://maven.apache.org/components/surefire/maven-failsafe-plugin/examples/fork-options-and-parallel-execution.html
Make sure JUnit4 is configured to parallelize them by method, class, etc..
And if you feel curious, a few months ago I published a blog post Integration Testing using Spring Boot, Postgres and Docker where each test connects to a Postgres DB running in a different container. I don't remember covering running the tests in parallel but that would be doable.
I've got a spring boot application that I'd like to automatically test.
I've written an #DataJpaTest unit test like the one here, and it works fine, however it slows down the build process considerably due to having to start spring.
I'd like to run these tests as integration tests using the maven failsafe plugin, but I can figure out how to do this. If I rename the tests so they match *IT.java, failsafe tries to run them, but spring doesn't start and I get java.lang.NoClassDefFoundError errors for the injected repositories.
What's the best way to run spring boot tests as integration tests?
Update 18 March:
With a dependency on spring-boot-starter-test:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
</dependency>
And the following plugin configuration:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<plugin>
The integration tests execute correctly using mvn failsafe:integration-test. However, I'd like the tests to be run when I do mvn install, so I updated the plugin config to:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>integration-test</goal>
<goal>verify</goal>
</goals>
</execution>
</executions>
<plugin>
And now the spring framework doesn't start when I run the test with mvn verify, so I get java.lang.NoClassDefFoundError for the JpaRepository I'm trying to inject and test.
I have a project using jacoco version 0.7.1.201405082137 and maven 3.0.5. In the project I have some unit tests, and some tests created using arquillian.
To distinguish between the unit tests and integration ones, I created two junit categories: one called FastTest and another called SlowTest.
In the maven profile that I use to run all tests I have this plugins configured:
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.17</version>
<configuration>
<groups>SlowTest,FastTest</groups>
<systemPropertyVariables>
<arquillian.launch>wildfly_8_x</arquillian.launch>
</systemPropertyVariables>
</configuration>
</plugin>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>${version.jacoco}</version>
<executions>
<execution>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
<execution>
<id>report</id>
<phase>prepare-package</phase>
<goals>
<goal>report</goal>
</goals>
</execution>
</executions>
When I leave both categories in I get only the coverage for the tests annotated with SlowTest. But all the tests run. If I run only the ones annotated with FastTest I get their correct coverage too.
How can I set up jacoco to get the correct coverage when running both kinds of tests?
Small tip:
<groups> tag takes full class name. So my question: is SlowTest.class interface placed in the default package? If not you should provide full path, something like: <groups>com.mycompany.project.SlowTest</groups>
And little advice:
Good practice is to distinguish unit and integration tests - and thus run them separately. Maven accomplishes this by two plugins: maven-surefire-plugin and maven-failsafe-plugin.
First is designed to run unit tests with mvn test. Second is designed to run your integration tests with mvn failsafe:integration-test. This answer may be useful to shed some light.
I have webapp which provides web service. I want to perform JUnit tests with SoapUI to check if this service is working properly.
But to test web service application has to be deployed to my Tomcat 7 server.
I have no idea how to configure maven to build war, then deploy it to tomcat (ideally: to run separate tomcat instance for this) and then to run JUnit tests.
I will appreciate any help.
I am using maven 2.2.1
There are a number of schools of thought as to how to handle this type of integration test with Maven.
I should point out that when you are deploying an application to an application server, you are not in the realm of unit testing any more. Because the entire application is being deployed within a container, you are testing the integration of those two components.
Now there is nothing wrong with using JUnit for running integration tests (though there are some limitations that you may hit, for example unit tests should not care about the sequencing of individual tests - assuming you are writing them correctly - so JUnit enforces this by not guaranteeing any sequence of execution... prior to Java 1.7 the execution order was accidentally implied by the order of test methods within a class, but it was not part of the JUnit contract... Some people switch to other testing frameworks for their integration tests, e.g. TestNG, if they find the unit test focus of JUnit is getting in the way of their test development)
The key point to keep in mind is that the Maven lifecycle uses the test phase for the execution of unit tests.
When it comes to integration tests there are two (and a half) schools of thought as to the right way to handle the tests with Maven.
School 1 - Failsafe and integration-test/verify
This school of thought uses the phases after package to start up a container, run the integration tests, tear down the container, and finally check the test results and fail the build in the event of test failures.
NEVER EVER RUN mvn integration-test as that will not tear down the container correctly, any time you think you want to type mvn integration-test you actually want to type mvn verify (oh look, it's shorter and easier to type also... bonus)
So with this you do the following:
Bind tomcat7:run to the pre-integration-test phase with fork=true
Bind failsafe:integration-test to the integration-test phase
Bind tomcat7:shutdown to the post-integration-test phase
Bind failsafe:verify to the verify phase.
For extra brownie points you would use build-helper-maven-plugin:reserve-network-port bound to the validate phase to ensure that the test server is started on an unused network port and then either use resource filtering against the test resources to pass the port through to the tests or use a system property passed through systemPropertyVariables to make the port number available to the tests.
Advantages
Clean Maven build
If the tests fail, you cannot release the project
Can move the integration tests into a separate profile (by convention called run-its) if the tests are too slow to run every build.
Disadvantages
Hard to run the tests from an IDE. All the integration tests start/end in IT and while Maven knows to run tests starting/ending in Test with Surefire and run tests starting/ending in IT with Failsafe, your IDE probably doesn't. Additionally, your IDE is not going to start the container for you, so you have to do a lot of work by hand to actually run the tests manually.
Debugging the tests potentially requires attaching two debuggers, e.g. one to debug the application running in container and the other to debug the test cases.
mvnDebug -Dmaven.failsafe.debug=true verify
Couples your tests to the Maven build process.
School 2 - Separate module
This school of thought moves the integration tests into a separate module that depends on the war module and copies the war into the test resources using, e.g. dependency:copy-dependencies bound to the generate-test-resources phase coupled with a Tomcat7 dependency to test against.
The test cases themselves start up the Tomcat7 container using embedded mode
Advantages
Tests can run in IDE
Integration tests are separated from Unit tests, so asking the IDE to run all tests will not kick off the slower tests
Disadvantages
The war artifact is only rebuilt if you go past the package phase, consequently, you need to run at least mvn clean package periodically to refresh the code under test when using the IDE.
The failure of the integration tests does not break the build of the war module, so you can end up releasing a broken war artifact and then have the reactor build fail for the integration test module. Some people counteract this issue by having the integration test module within src/it and using Maven Invoker Plugin to run the tests... though that provides a poorer IDE integration, so I do not recommend that line.
Hard to get a consolidated test coverage report from Maven.
Have to code the container start/stop yourself from within your test cases.
School 2.5 - Failsafe with the test cases starting their own Tomcat7 server
This is a kind of hybrid of the two approaches.
You use Failsafe to execute the tests, but the tests themselves are responsible for starting and stopping the Tomcat7 container that you want to test in.
Advantages
Don't have to configure the server start/stop in Maven pom
IDE can safely run all tests (though the integration tests may be slower and you may want to not run them, but it's not like they will all fail unless there is a test failure)
Easier to debug the tests from your IDE (only one process to attach against, and the IDE usually makes it easy to debug tests by providing a special test runner)
Disadvantages
Have to code the container start/stop yourself from within your test cases
I hope the above helps you understand the options you have. There may be other tweaks but in general the above are considered the best practice(s) for integration testing with Maven at present.
#Stephen Connolly - your answer above was really good. I thought I'd kick in and show a full configuration for what you termed a School 1 response.
This configuration:
runs unit tests separately from integration tests. It uses the #Category annotation on the root classes that unit tests and integration tests extend.
before integration tests it starts the dependent application (loaded as a maven dependency at runtime) on the local machine, by finding an open port
after integration tests it tears down the dependent application
There's other stuff in there like how to set certain system properties on the dependent application only.
So far this configuration is working awesome..

As Stephen Connolly explains there is no a direct way to configure this. I will explain how to solve this using failsafe plugin. In the maven lifecycle type of test can be tested. Unit testing one of them and another one is integrate testing. Unit testing can be run in the test stage of maven lifecycle. When you want to do integrate test it can be done in verify stage. If you want to know the difference between unit testing and integrate testing, this is a good one. By default unit test classes should be in ***/*Test.java, and **/*TestCase.java this format. The failsafe plugin will look for **/IT*.java, **/*IT.java, and **/*ITCase.java.
Here is an example.
Here I have one unit test class and one integrate test class. Now I will explain, how should be the looks like maven pom.xml. Build section of maven configuration should look like this.
<build>
<plugins>
<plugin>
<artifactId>maven-war-plugin</artifactId>

Unit tests are run before deploying the web app(war file). But integrate tests are run in verify stage. I hope your requirement is satisfied in this stage.
We have unit tests (mockito) and integration tests (in-memory database)
We'd like maven to not run the integration tests as part of 'mvn install'.
Basically I think this means reconfiguring the lifecyle so that integration-test
comes between install and deploy. Is this possible?
The reason for this would be that the integration tests are somewhat time consuming
and so we don't want them to run every time a developer does an install. But we would
like them to be run before the project can be released, for example.
Check the docs for the plugin you use for running integration tests (possibly Failsafe) - simply exclude the tests, or set the plugin execution to false.
Does integration-tests just execute a single plugin (like surefire)? If so, it is probably easier to just bind the plugin execution to a different phase:
<project>
...
<build>
<plugins>
<plugin>
...
<executions>
<execution>
<id>execution1</id>
<phase>install</phase>
<configuration>
...
</configuration>
<goals>
<goal>test</goal>
</goals>
</execution>
