Using with JUnit 5 @RunWith(JUnitPlatform.class) causes multiple deployment.

[charleech]

Using with JUnit 5 @RunWith(JUnitPlatform.class) causes multiple deployment.

Since the JUnit5 does not have the Test Suite and provide the interim solution by the JUnitPlatform which requires the junit:junit:4.13.2 in the classpath.

• Using JUnit 4 to run the JUnit Platform
• Using JUnit 4 to run the JUnit Platform: Test Suite
• Are test suites considered deprecated in JUnit5?

Then the test suite will be like the following: -

import org.junit.platform.runner.JUnitPlatform;
import org.junit.platform.suite.api.IncludeClassNamePatterns;
import org.junit.platform.suite.api.SelectClasses;
import org.junit.platform.suite.api.SuiteDisplayName;
import org.junit.runner.RunWith;

/**
 * This is a first test suite.
 */
@RunWith(JUnitPlatform.class)
@SuiteDisplayName("JUnit Platform Suite Demo")
@SelectClasses({
    MyCdiJunit5IntgrtnTester.class
})
@IncludeClassNamePatterns("^(Test.*|.+[.$]Test.*|.*Tests?|.*Tester)$")
public class MyCdiJunit5IntgrtnTestSuite {

}

/**
 * This is a second test suite.
 */
@RunWith(JUnitPlatform.class)
@SuiteDisplayName("JUnit Platform Suite Demo")
@SelectClasses({
    MyCdiJunit5IntgrtnTester.class
})
@IncludeClassNamePatterns("^(Test.*|.+[.$]Test.*|.*Tests?|.*Tester)$")
public class MyCdiJunit5Round2IntgrtnTestSuite {

}

By using it, it causes the Arquillian-Suite-Extension to deploy multiple times (each time for each test suite) !

The reproducer

I've create the reproducer at https://github.com/charleech/arquillian-junit5-payara

How to execute

1.1 The multiple tester without test suite

This is a base line which use pure JUnit 5 without any dependency to JUnit4 and JUnit 5 Platform.

cd path/to/arquillian-junit5-payara

mvn clean install -N

cd path/to/arquillian-junit5-payara/my-cdi-junit5-multiple-tester

mvn clean install -Dpayara-embedded=true

#
# Everything works fine !
#

1.2 The multiple test suite

This is a reproducer which use JUnit 5 with dependency to JUnit4 and JUnit 5 Platform.

cd path/to/arquillian-junit5-payara

mvn clean install -N

cd path/to/arquillian-junit5-payara/my-cdi-junit5-multiple-testsuite

mvn clean install -Dpayara-embedded=true

@charleech Plugin works with juint5 (just need few beta dependencies). Here you have fully working solution https://github.com/ingwarsw/arquillian-suite-extension/tree/master/test-suites/junit5

Im not sure how suites works in junit5.. but seems arquillian and plugin dont use them..

[charleech]

Hi @ingwarsw, I've followed this repository example at https://github.com/ingwarsw/arquillian-suite-extension/tree/master/test-suites/junit5 and implemented as https://github.com/charleech/arquillian-junit5-payara/tree/main/my-cdi-junit5-multiple-tester as the following example: -

@ArquillianSuiteDeployment
public class ArquillianSuiteDeployments {
    @Deployment(name = "payara-evaluation-base")
    public static WebArchive createDeployment() throws IOException {
        return ShrinkWrap.create()....
    }
}
@ExtendWith(ArquillianExtension.class)
public class MyCdiJunit5IntgrtnTester {
    @Inject
    private Greetable greeter;

    @Test
    public void whenGreet() {
        // use the injected greeter and assert
    }
}
@ExtendWith(ArquillianExtension.class)
public class MyCdiJunit5Round2IntgrtnTester {
    @Inject
    private Greetable greeter;

    @Test
    public void whenGreet() {
        // use the injected greeter and assert
    }
}

Everything works like a charm and is able to confirm that our arquillian-suite-extension works perfectly with latest Arquillian , latest Surefire/Failsafe and latest JUnit5 .

[charleech]

Anyhow when I've tried to use the workaround test suite as mentioned at the formal JUnit5 document as the following: -

• https://junit.org/junit5/docs/current/user-guide/#running-tests-junit-platform-runner
• https://junit.org/junit5/docs/current/user-guide/#running-tests-junit-platform-runner-test-suite
• https://stackoverflow.com/questions/50565724/are-test-suites-considered-deprecated-in-junit5

I also have tried to implement the test suite as https://github.com/charleech/arquillian-junit5-payara/tree/main/my-cdi-junit5-multiple-testsuite as the following example: -

import org.junit.platform.runner.JUnitPlatform;
import org.junit.platform.suite.api.IncludeClassNamePatterns;
import org.junit.platform.suite.api.SelectClasses;
import org.junit.platform.suite.api.SuiteDisplayName;
import org.junit.runner.RunWith;

/**
 * This is a first test suite.
 */
@RunWith(JUnitPlatform.class)
@SuiteDisplayName("JUnit Platform Suite Demo")
@SelectClasses({
    MyCdiJunit5IntgrtnTester.class
})
@IncludeClassNamePatterns("^(Test.*|.+[.$]Test.*|.*Tests?|.*Tester)$")
public class MyCdiJunit5IntgrtnTestSuite {

}

/**
 * This is a second test suite.
 */
@RunWith(JUnitPlatform.class)
@SuiteDisplayName("JUnit Platform Suite Demo")
@SelectClasses({
    MyCdiJunit5IntgrtnTester.class
})
@IncludeClassNamePatterns("^(Test.*|.+[.$]Test.*|.*Tests?|.*Tester)$")
public class MyCdiJunit5Round2IntgrtnTestSuite {

}

Sadly, it makes our arquillian-suite-extension to do a multiple deployments.

[charleech]

I'm not sure if it is possible to enhance the arquillian-suite-extension so that it may support the JUnit5 test suite or not.

Could you please help to consider and advise?

[charleech]

I've just found that the JUnit 5 version 5.8.0-M1 and org.junit.platform:junit-platform-suite:1.0.8-M1 introduces @Suite natively (without any dependency to JUnit 4 anymore) as the following :-

• https://junit.org/junit5/docs/snapshot/user-guide/#junit-platform-suite-engine
• https://github.com/junit-team/junit5/pull/2416

Then the pure JUnit 5 test suite will be look like the following: -

import org.junit.platform.suite.api.IncludeClassNamePatterns;
import org.junit.platform.suite.api.SelectClasses;
import org.junit.platform.suite.api.Suite;
import org.junit.platform.suite.api.SuiteDisplayName;

/**
 * This is a first test suite.
 */
@Suite
@SuiteDisplayName("JUnit Platform Suite Demo")
@SelectClasses({
    MyCdiJunit5IntgrtnTester.class
})
@IncludeClassNamePatterns("^(Test.*|.+[.$]Test.*|.*Tests?|.*Tester)$")
public class MyCdiJunit5IntgrtnTestSuite {

}

/**
 * This is a second test suite.
 */
@Suite
@SuiteDisplayName("JUnit Platform Suite Demo")
@SelectClasses({
    MyCdiJunit5IntgrtnTester.class
})
@IncludeClassNamePatterns("^(Test.*|.+[.$]Test.*|.*Tests?|.*Tester)$")
public class MyCdiJunit5Round2IntgrtnTestSuite {

}

I also have a chance to update the https://github.com/charleech/arquillian-junit5-payara/tree/main/my-cdi-junit5-multiple-testsuite to use the @Suite and also still face the multiple deployment as the following log :-
