Comment exécuter un test unitaire avec Maven
Vous pouvez utilisermvn test pour exécuter un test unitaire dans Maven. Quelques exemples:
# Run all the unit test classes. $ mvn test # Run a single test class. $ mvn -Dtest=TestApp1 test # Run multiple test classes. $ mvn -Dtest=TestApp1,TestApp2 test # Run a single test method from a test class. $ mvn -Dtest=TestApp1#methodname test # Run all test methods that match pattern 'testHello*' from a test class. $ mvn -Dtest=TestApp1#testHello* test # Run all test methods match pattern 'testHello*' and 'testMagic*' from a test class. $ mvn -Dtest=TestApp1#testHello*+testMagic* test
Lemaven-surefire-plugin par défaut est obsolète, assurez-vous de mettre à jour la dernière pour prendre en charge les nouvelles fonctionnalités, comme la correspondance de modèles ou exécuter une seule méthode de test, etc.

1. Projet Maven Java
Passez en revue un projet Java simple sur la manière d'exécuter les classes de test unitaire dans Maven.
1.1 Directory Structure.
1.2 Maven + JUnit 5 examples.
pom.xml
4.0.0 com.example.examples maven-unit-test jar 1.0-SNAPSHOT UTF-8 1.8 1.8 org.junit.jupiter junit-jupiter-engine 5.3.1 test maven-unit-test org.apache.maven.plugins maven-surefire-plugin 2.22.0
1.3 Two Java classes, later we will create unit test classes for it.
MagicBuilder.java
package com.example.examples;
public class MagicBuilder {
public static int getLucky() {
return 7;
}
}
MessageBuilder.java
package com.example.examples;
public class MessageBuilder {
public static String getHelloWorld(){
return "hello world";
}
public static int getNumber10(){
return 10;
}
}
1.4 Test class for MagicBuilder
TestMagicBuilder.java
package com.example.examples;
import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.assertEquals;
public class TestMagicBuilder {
@Test
public void testLucky() {
assertEquals(7, MagicBuilder.getLucky());
}
}
1.5 Test class for MessageBuilder
pom.xml
package com.example.examples;
import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.assertEquals;
public class TestMessageBuilder {
@Test
public void testHelloWorld() {
assertEquals("hello world", MessageBuilder.getHelloWorld());
}
@Test
public void testNumber10() {
assertEquals(10, MessageBuilder.getNumber10());
}
}
2. Test de Maven
2.1 Run all test classes.
Terminal
$ mvn test [INFO] ------------------------------------------------------- [INFO] T E S T S [INFO] ------------------------------------------------------- [INFO] Running com.example.examples.TestMagicBuilder [INFO] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.004 s - in com.example.examples.TestMagicBuilder [INFO] Running com.example.examples.TestMessageBuilder [INFO] Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.001 s - in com.example.examples.TestMessageBuilder [INFO]
2.2 Run a single test class TestMessageBuilder
Terminal
$ mvn -Dtest=TestMessageBuilder test [INFO] ------------------------------------------------------- [INFO] T E S T S [INFO] ------------------------------------------------------- [INFO] Running com.example.examples.TestMessageBuilder [INFO] Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.004 s - in com.example.examples.TestMessageBuilder [INFO]
2.3 Run a single test method testHelloWorld() from the test class TestMessageBuilder
Terminal
$ mvn -Dtest=TestMessageBuilder#testHelloWorld test [INFO] ------------------------------------------------------- [INFO] T E S T S [INFO] ------------------------------------------------------- [INFO] Running com.example.examples.TestMessageBuilder [INFO] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.004 s - in com.example.examples.TestMessageBuilder [INFO]
