In Junit 5, How to Run Code Before All Tests

JUnit 5. How to run code before / after all tests without extension

Maybe it was added later, but the answer you referenced actually includes a hook to run code after all tests of all classes have finished, by using a CloseableResource. This is exactly what you're looking for.

And you can also annotate your super class with the extension, as @ExtendWith is inherited. If you use your custom meta-annotation, you'll have to annotate that as @Inherited, too. In this way, you can do the stuff in one place.

BTW: it's often even easier to not inherit from common super classes but to use extensions everywhere instead.

Run code in junit 5 after all tests in all test classes terminated

In general there are several solutions for the problem.

• You could define the beforeAll/afterAll on a parent class from which all of your tests inherit. Another option would be to try to define the beforeAll/afterAll on an interface (I'm not 100% sure if this works; I would say it should). In beforeAll you could initialize your setup and in the afterEachCallBack your can collect all the data you need for a single test. So this is called after each test.

• You could implement an extension which uses the callbacks of JUnit which are BeforeAllCallback and AfterAllCallBack which could handle that. Based on what you exactly need you may need to implement beforeEachCallBack/afterEachCallBack as well.

• Another option would be to use the Test Execution listener
  where you can use testPlanExecutionStarted and testPlanExecutionFinished which you should implemented to record and get all you need.

I've made an example project which shows the usage of the JUnit Jupiter listener.

Junit 5 suite Does not run @BeforeAll and@AfterAll

The @BeforeAll Denotes that the annotated method should be executed before all @Test, @RepeatedTest, @ParameterizedTest, and @TestFactory methods in the current class; analogous to JUnit 4’s @BeforeClass. Such methods are inherited (unless they are hidden or overridden) and must be static (unless the "per-class" test instance lifecycle is used).

Same story holds for @AfterAll so consider to move start() and end() methods to your TestDemoClass1 and TestDemoClass2 classes or extend your test classes to some BaseClass and keep this methods inside it.

public class BaseTest {

    @BeforeAll
    public static void start() throws Exception {
        System.out.println("Before All from Suite1");
    }

    @AfterAll
    public static void end() throws Exception {
        System.out.println("After All from Suite1");
    }
}

And your test classes

public class SampleTestOne extends BaseTest {
    @Test
    public void testOne(){
        System.out.println("Extended test passed!");
    }

    @Test
    public void testTwo(){
        System.out.println("Extended test passed!");
    }
}

public class SampleTestTwo extends SampleTestOne {
    @Test
    public void testThree(){
        System.out.println("test passed");
    }
}

And the final result

Alternatively you can create custom extension to run code before all your test context which fully explained here.

Junit5- jupiter all tests suite @BeforeAll @AfterAll not working

I may cite the JUnit 5 migration tipps:

@Before and @After no longer exist; use @BeforeEach and @AfterEach instead.

@BeforeClass and @AfterClass no longer exist; use @BeforeAll and @AfterAll instead.

But these annotations should be used in your test class. The methods in your suite class will not be invoked this way. And you should be aware of the fact that suites and JUnit 5 are still work in progress (see Issue 744).

Junit5 Parameterized Test LifeCycle. why @BeforeAll and static block run after all the tests

Cannot reproduce. The following test file:

package com.example;

import org.junit.jupiter.api.AfterAll;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.params.ParameterizedTest;
import org.junit.jupiter.params.provider.CsvSource;

import static org.junit.jupiter.api.Assertions.assertEquals;

class JUnitTests {

  static {
    System.out.println("Static initializer...");
  }

  @BeforeAll
  static void beforeAll() {
    System.out.println("Before all...");
  }

  @BeforeEach
  void beforeEach() {
    System.out.println("Before each...");
  }

  @ParameterizedTest
  @CsvSource(value = {"5,5,10", "2,3,5"})
  void parameterizedTest(int x, int y, int r) {
    System.out.printf("Parameterized test (%d, %d, %d)...%n", x, y, r);
    assertEquals(r, x + y, () -> String.format("%d + %d expected to equal %d", x, y, r));
  }

  @AfterEach
  void afterEach() {
    System.out.println("After each...");
  }

  @AfterAll
  static void afterAll() {
    System.out.println("After all...");
  }
}

Compiled and executed with the following Gradle build script:

plugins {
    java
}

repositories {
    mavenCentral()
}

dependencies {
    testImplementation("org.junit.jupiter:junit-jupiter:5.8.2")
}

tasks.test {
    useJUnitPlatform()
    testLogging {
        showStandardStreams = true
    }
}

Gives the following output:

> Task :test

JUnitTests STANDARD_OUT
    Static initializer...
    Before all...

JUnitTests > parameterizedTest(int, int, int) > com.example.JUnitTests.parameterizedTest(int, int, int)[1] STANDARD_OUT
    Before each...
    Parameterized test (5, 5, 10)...
    After each...

JUnitTests > parameterizedTest(int, int, int) > com.example.JUnitTests.parameterizedTest(int, int, int)[2] STANDARD_OUT
    Before each...
    Parameterized test (2, 3, 5)...
    After each...

JUnitTests STANDARD_OUT
    After all...

As you can see, everything is executed in the expected order.
