如何在多模块项目中使用Gradle而不是使用JUnit5和SpringBoot2的intelliJ运行测试

本文介绍了如何在多模块项目中使用Gradle而不是使用JUnit5和SpringBoot2的intelliJ运行测试的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我创建了一个空的gradle项目，其中的单个模块(子项目)也作为gradle项目，但带有Spring boot 2.

I created an empty gradle project with single module inside (subproject) also as gradle project but with Spring boot 2.

主要(无标题1)build.gradle:

Main (untitled1)build.gradle:

group 'com.example'
version '1.0-SNAPSHOT'

allprojects {
    repositories {
        mavenCentral()
    }
}

settings.gradle:

settings.gradle:

rootProject.name = 'main-project'
include 'new-one'

子项目(新项目):构建gradle:

sub project (new-one):build gradle:

plugins {
    id("java")
    id("org.springframework.boot") version "2.1.8.RELEASE"
    id("io.spring.dependency-management") version "1.0.8.RELEASE"
}

group = 'com.example'
version '1.0-SNAPSHOT'

sourceCompatibility = 1.12

dependencies {
    implementation 'org.springframework.boot:spring-boot-dependencies:2.0.5.RELEASE'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'

    def junit = '5.5.2'
    testImplementation ("org.junit.jupiter:junit-jupiter-api:${junit}")
    testImplementation ("org.junit.jupiter:junit-jupiter-params:${junit}")
    testImplementation ("org.assertj:assertj-core:3.11.1")
    testRuntime("org.junit.jupiter:junit-jupiter-engine:${junit}")
}

test {
    useJUnitPlatform()
}

使用测试运行程序运行测试，如下所示:IntelliJ idea编译并通过了测试，但是当我使用gradle时，如果运行单个测试，它将返回:

Running test using test runner as: IntelliJ idea compiles and passes the test, but when I use gradle it returns if I run single test:

或者，如果我尝试使用测试运行程序(在build.gradle中)运行所有测试，则

Or this, if I try to run all tests using test runner (in build.gradle)

test {
    useJUnitPlatform()
}

我使用:

IntelliJ 2019.2
Spring boot 2.1.8
JUnit 5.5.2
Gradle 5.6.2
Java 1.12

推荐答案

如 https://github.com/junit-team/junit5-samples/blob/r5.5.2/junit5-jupiter-starter-gradle/build.gradle 我建议将Jupiter依赖项定义为:

As shown in https://github.com/junit-team/junit5-samples/blob/r5.5.2/junit5-jupiter-starter-gradle/build.gradle I recommend to define the Jupiter dependencies as:

testImplementation('org.junit.jupiter:junit-jupiter:5.5.2')

希望可以解决问题.
