Quiero implementar una prueba Junit 5 en el proyecto Gradle. Intenté esto:

Configuración de Gradle:

 plugins { id 'org.springframework.boot' version '2.5.5' id 'io.spring.dependency-management' version '1.0.11.RELEASE' id 'java' } group = 'test' version = '0.0.1' sourceCompatibility = '17' repositories { mavenCentral() } ext { set('springCloudVersion', "2020.0.4") } dependencies { ............... testImplementation 'org.springframework.boot:spring-boot-starter-test' testImplementation 'org.junit.jupiter:junit-jupiter-api:5.8.2' testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.8.2' } dependencyManagement { imports { mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}" } } test { useJUnitPlatform() }

Prueba Junit:

 import org.junit.jupiter.api.DisplayName; import org.junit.jupiter.api.Test; import org.junit.jupiter.api.Timeout; import java.util.concurrent.TimeUnit; public class GeneratePdf { @DisplayName("Test MessageService.get()") @Test @Timeout(value = 60, unit = TimeUnit.SECONDS) public void generatePdfFileTes() throws InterruptedException { System.out.println("test!"); } }

Cuando ejecuto el código me sale error:

 Internal Error occurred. org.junit.platform.commons.JUnitException: TestEngine with ID 'junit-jupiter' failed to discover tests at

¿Sabes cómo se puede solucionar este problema?

EDITAR:

 import org.junit.jupiter.api.Test; public class InvoiceTests { @Test public void generateTest() { System.out.println("test!"); } }

Intenté esto pero nuevamente no funciona.
