Gradle不运行测试

Question

在我的Gradle项目中，我有一个非常简单的JUnit测试：

import org.junit.jupiter.api.Test
import static org.junit.jupiter.api.Assertions.fail

class ApiCallerTest {

    @Test
    void testSetApiKey() {
        fail();
    }
}

当我在IntelliJ中运行测试时，我会得到一个任务列表，其中包含构建成功的消息。例如：

Testing started at 19:52 ...
> Task :cleanTest UP-TO-DATE
> Task :compileJava UP-TO-DATE
> Task :compileGroovy NO-SOURCE
> Task :processResources NO-SOURCE
> Task :classes UP-TO-DATE
> Task :compileTestJava NO-SOURCE
> Task :compileTestGroovy NO-SOURCE
> Task :processTestResources NO-SOURCE
> Task :testClasses UP-TO-DATE
> Task :test NO-SOURCE
BUILD SUCCESSFUL in 0s

这不应该发生，因为我期待测试失败。我还得到一条消息“测试事件没有收到”。

plugins {
    id 'groovy'
    id 'java'
}

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

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.codehaus.groovy:groovy-all:2.3.11'
    testImplementation('org.junit.jupiter:junit-jupiter:5.6.0')
}

test {
    useJUnitPlatform()
}

Internal Error occurred.

您可以使用官方的JUnit5-Samples中的配置。在这里可以找到junit5-jupiter-starter-gradle-groovy项目，该项目使用以下配置：

plugins {
    id 'groovy'
    id 'eclipse' // optional (to generate Eclipse project files)
    id 'idea' // optional (to generate IntelliJ IDEA project files)
}

repositories {
    mavenCentral()
}

dependencies {
    implementation(localGroovy())
    testImplementation('org.junit.jupiter:junit-jupiter:5.6.0')
}

test {
    useJUnitPlatform()
    testLogging {
        events "passed", "skipped", "failed"
    }
}

它可以与Gradle6.0.1、Java8和11一起工作。

为了运行测试，您可以使用以下命令:gradle test或在IDE中配置，如图所示：
