项目管理
HarmonyOS
我想在 Gradle 项目中实施 Junit 5 测试。我试过这个：
摇篮配置：
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()
}
联合测试：
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!");
}
}
当我运行代码时出现错误：
Internal Error occurred.

你知道如何解决这个问题吗？
编辑：
import org.junit.jupiter.api.Test;
public class InvoiceTests {
@Test
public void generateTest()
{
System.out.println("test!");
}
}
我试过了，但还是没用。

您遵循的项目结构是什么？我记得刚开始的时候遇到过类似的问题，所以基本上我所做的就是遵循这个结构：
除了上述结构之外，请确保按照 @johanneslink 的回答 中提到的正确格式命名测试类
