Gradle中使用Junit5做单元测试备忘_gradle junit5

配制build.gradle

dependencies {
    testImplementation(platform('org.junit:junit-bom:5.7.2'))
    testImplementation('org.junit.jupiter:junit-jupiter')
}
 
test {
    useJUnitPlatform()
    testLogging {
        events "passed", "skipped", "failed"
    }
}

测试示例

import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;
 
import java.time.Duration;
 
import static org.junit.jupiter.api.Assertions.assertAll;
import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.junit.jupiter.api.Assertions.assertThrows;
import static org.junit.jupiter.api.Assertions.assertTimeout;
 
@DisplayName("Junit5单元测试示例")
public class Junit5Test {
 
    @Test
    @DisplayName("DisplayName注解测试")
    void testWithDisplayName() {
    }
 
    @Test
    @DisplayName("Assertions.assertEquals测试")
    void testAssertEquals(){
        String name = "hello junit5";
        assertEquals("hello junit5",name,"name not same");
    }
 
    @Test
    @DisplayName("Assertions.assertAll测试")
    void testAssertAll(){
        assertAll("判断是否全部相同",
                () -> assertEquals("hello", "hello"),
                () -> assertEquals("world", "world")
        );
    }
 
    @Test
    @DisplayName("Assertions.assertThrows测试")
    void exceptionTesting() {
        Exception exception = assertThrows(ArithmeticException.class, ()->{
            System.out.println(1/0);
        });
        assertEquals("/ by zero", exception.getMessage());
    }
 
    @Test
    @DisplayName("Assertions.assertTimeout测试")
    void timeoutExceeded() {
        assertTimeout(Duration.ofMillis(10), () -> {
            Thread.sleep(9);
        });
    }
 
}
