无法在IntelliJ 2018.2.2 w / Gradle 4.9中运行JUnit 5测试

Question

我正在尝试从Intelli 2018.2.2社区版运行单个JUnit 5单元测试。该项目正在使用Gradle v4.9。

无论出于何种原因，当尝试单独运行测试方法或作为测试类时，会产生相同的输出：

Empty test suite.

在命令行上运行gradle test运行得很好。

Gradle配置是：apply plugin：'java'

repositories {
    jcenter()
}

dependencies {
    testCompile("org.junit.jupiter:junit-jupiter-api:5.2.0")
    testRuntime("org.junit.jupiter:junit-jupiter-engine:5.2.0")
}

test {
    useJUnitPlatform()
}

我已经阅读过类似于IntelliJ 2016的类似问题，但不是更新的版本。

其他人遇到这个问题？似乎IntelliJ正在使用其他方法来启动测试而不是Gradle，但目前还不清楚是什么。

为了更好的衡量，我检查了YouTrack类似的堆栈跟踪无济于事。

指针赞赏！

你能在IntelliJ中取悦你的设置吗？您必须打开“首选项”或“设置”对话窗口。在那里，您可以搜索Gradle，然后查找构建，执行，部署|构建工具| Gradle | Runner和Select Gradle Test Runner。

默认情况下，它是Platform Test Runner
