带有IntelliJ和Gradle的Junit5

Question

我已经添加了junit-jupiter-api版本5.0.0-M6

WARNING: TestEngine with ID 'junit-jupiter' failed to discover tests
java.lang.NoSuchMethodError: org.junit.platform.engine.TestDescriptor.pruneTree()V

Aug 02, 2017 2:44:56 PM org.junit.platform.launcher.core.DefaultLauncher handleThrowable
WARNING: TestEngine with ID 'junit-vintage' failed to discover tests
java.lang.NoSuchMethodError: org.junit.platform.engine.EngineDiscoveryRequest.getDiscoveryFiltersByType(Ljava/lang/Class;)Ljava/util/List;

WARNING: TestEngine with ID 'junit-jupiter' failed to discover tests
java.lang.NoSuchMethodError: org.junit.platform.engine.TestDescriptor.pruneTree()V

注意：我还没有迁移任何测试，所有测试都是JUnit4语法。

Answer 1

添加特定的依赖项可以解决这个问题。

注意：在2017.2.0以上更新INTELLIJ，因为JUNIT LAUNCHER有一个BUG

如果你使用Eclipse。

"org.junit.jupiter:junit-jupiter-params:5.0.0"
//for JUnit5 parametrized tests.

"org.junit.jupiter:junit-jupiter-api:5.0.0"
//JUnit5 API

"org.junit.vintage:junit-vintage-engine:4:12.0"
//for legacy JUnit4 tests

"org.junit.jupiter:junit-jupiter-engine:5.0.0"
//for JUnit5 tests

"org.junit.platform:junit-platform-launcher:1.0.0
//to handle default launcher

有关如何安装JUnit5的其他信息

从Gradle的4.6版本开始，Gradle就不再需要插件了，Gradle支持Junit5，只需做：vintage runner的版本现在与Junit5版本相同。

dependencies {

    testImplementation "org.junit.jupiter:junit-jupiter-params:$junitVersion"
    testImplementation "org.junit.jupiter:junit-jupiter-api:$junitVersion"

    testRuntimeOnly "org.junit.vintage:junit-vintage-engine:$junitVersion"
    testRuntimeOnly "org.junit.jupiter:junit-jupiter-engine:$junitVersion"
}

test {  
    useJUnitPlatform {
        includeEngines 'junit-jupiter', 'junit-vintage'
    }
}
