【问题描述】：

我正在尝试使用 spring boot 项目配置 gradle id 'jvm-test-suite' 插件

plugins {
    id 'java'
    id 'jvm-test-suite'
    id 'org.springframework.boot' version '3.0.0'
    id 'io.spring.dependency-management' version '1.1.0'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'

repositories {
    mavenCentral()
}

ext {
    set('testcontainersVersion', "1.17.6")
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-mongodb'
    implementation 'org.springframework.boot:spring-boot-starter-web'
}

dependencyManagement {
    imports {
        mavenBom "org.testcontainers:testcontainers-bom:${testcontainersVersion}"
    }
}

testing {
    suites {
        configureEach {
            useJUnitJupiter()
            dependencies {
                implementation project()
                implementation 'org.springframework.boot:spring-boot-starter-test'
                implementation 'org.testcontainers:junit-jupiter'
                implementation 'org.testcontainers:mongodb'
            }
        }
        test {


        }

        integrationTest(JvmTestSuite) {

        }
    }
}

但我在集成测试中遇到以下错误

import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class DemoApplicationTests {

    @Test
    void contextLoads() {
    }

}

错误：

【解决方案1】：

当类的包名与集成测试的包名不同时，我得到了完全相同的错误。更具体地说，我的课程“GreetingController”在文件夹中
../src/main/kotlin/com/kotlinspring/controller
我的课程“GreetingControllerIntegrationTest”在文件夹中
../src/test/integration/com/cotlinspring/controller。
我通过将拼写错误的“cotlinspring”重命名为“Kotlinspring”来修复它。

【讨论】：

非常感谢你的帮助！您的回答是 100% 正确的。我非常感谢您的专业知识以及您花时间提供全面而有帮助的回复。再次感谢你！

【解决方案2】：

由于更改了我的 App 文件的目录路径而忘记将测试移动到同一路径，我遇到了同样的问题。检查两个文件（源文件和测试文件）是否在同一路径目录中

【讨论】：

感谢您的帮助。我今天学到了一些东西。

【解决方案3】：

我有同样的问题。我以为我的代码有问题。我在项目中搜索了对“getName”的引用，进行了一些调试，但仍然无法找出问题所在。将测试中的包名称更改为与修复它的项目相同的包名称。

【讨论】：

【解决方案4】：

我也面临同样的问题，重命名包对我不起作用。

但奇怪的是，在 @SpringBootTest 注释中提供 MainApplication 类名对我有用。

@SpringBootTest(classes = MainApplication.class)

我不确定这是如何以及为何起作用的。但会尝试弄清楚这一点并在此处发布原因
