Spock 测试因 org.junit.runners.model.InvalidTestClassError 失败：

Question

升级到 spock-core 2.0 后，我的测试失败并出现以下错误：

org.junit.runners.model.InvalidTestClassError: Invalid test class 'com.spock.test.TestSpockSpecification':
  1. No runnable methods

我在build.gradle 文件中使用以下配置：

testImplementation platform("org.spockframework:spock-bom:2.0-M5-groovy-3.0") //copied from spock example
testImplementation "org.spockframework:spock-core:2.0-M5-groovy-3.0"
implementation localGroovy() //3.0.7 as I am using gradle 7

我正在使用 junit 4 运行这些测试，有人可以帮忙

Spock 2.0 构建在 JUnit 5 之上，不适用于旧版 JUnit 4。此外，它已经发布了一段时间，没有理由使用里程碑。

有关完整示例，请参阅 this。注意useJUnitPlatform 部分。例如：

dependencies {
  testImplementation platform("org.codehaus.groovy:groovy-all:3.0.9")
  testImplementation platform("org.spockframework:spock-bom:2.0-groovy-3.0")
  testImplementation "org.spockframework:spock-core"

  testRuntimeOnly "net.bytebuddy:byte-buddy:1.11.18" // allows mocking of classes (in addition to interfaces)
  testRuntimeOnly "org.objenesis:objenesis:3.2"      // allows mocking of classes without default constructor (together with ByteBuddy or CGLIB)
}

test {
  useJUnitPlatform()
}
