java - Vertx ( vertx-Junit5 模块 ) 没有找到测试

Question

我尝试在我的 Vertx 项目中实现 Junit5。

只需添加 junit5 就可以正常工作，但是将 vertx-junit5 模块添加到项目后，测试引擎在查找测试时遇到问题

build.gradle:

buildscript {
    repositories {
        mavenCentral()
        dependencies {
            classpath 'org.junit.platform:junit-platform-gradle-plugin:1.1.0'
            classpath "org.sonarsource.scanner.gradle:sonarqube-gradle-plugin:2.5"            
        }
    }
}

plugins {
    id'java'
    id'application'
    id'eclipse'
}

apply plugin: 'org.junit.platform.gradle.plugin'
apply plugin: 'maven'
apply plugin: "org.sonarqube"

def vertxVersion = "3.5.1"
version = 0.4

compileJava.options.encoding = 'UTF-8'
tasks.withType(JavaCompile) {
    options.encoding = 'UTF-8'
}

dependencies {
    compile "io.vertx:vertx-core:$vertxVersion"
    compile "io.vertx:vertx-service-proxy:$vertxVersion"
    compile "io.vertx:vertx-sockjs-service-proxy:$vertxVersion"
    compile "io.vertx:vertx-hazelcast:$vertxVersion"
    compile "io.vertx:vertx-web:$vertxVersion"
    compile "io.vertx:vertx-config:$vertxVersion"

    compile group: 'org.slf4j', name: 'slf4j-log4j12', version: '1.7.6'

    testCompile group: 'io.vertx', name: 'vertx-unit', version: vertxVersion
    testCompile group: 'io.vertx', name: 'vertx-junit5', version: vertxVersion
    testCompile 'org.assertj:assertj-core:3.9.0'

    //Junit 5
    testCompile("org.junit.jupiter:junit-jupiter-api:5.1.0")
    testRuntime("org.junit.jupiter:junit-jupiter-engine:5.1.0")
    //Junit 5 vintage to run Junit4 Tests
    testCompile("junit:junit:4.12")
    testRuntime("org.junit.vintage:junit-vintage-engine:5.1.0")

    compileOnly 'io.vertx:vertx-codegen:3.4.2'
}

没有:

testCompile group: 'io.vertx', name: 'vertx-junit5', version: vertxVersion

测试引擎找到测试并且没有问题

但是有了这个依赖

No tests were found

我不明白为什么依赖会影响测试引擎

我使用的是 IntelliJ 2017.2.6

我用尽可能简单的测试来试试运气

import io.vertx.junit5.VertxTestContext;
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;

public class test {

    @Test
    @DisplayName("woop woooooooop")
    void Test(){
        VertxTestContext context = new VertxTestContext();
        context.succeeding();
    }
}

Answer 1

也许您错过了测试类的 JUnit5 扩展注释:

@ExtendWith(VertxExtension.class)
public class test {
    ...
}
