如何使kotlintest与Spring一起使用？

我正在尝试将kotlintest与Spring一起使用（不是Spring Boot，只是标准的spring-test）。我发现很难做到。关于我在做什么错的任何指示？我也是Kotlin的新手，所以我很可能做得不好。

到目前为止，这是我尝试过的：

import io.kotlintest.matchers.shouldBe
import io.kotlintest.specs.BehaviorSpec

import org.junit.ClassRule
import org.junit.Rule

import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration
import org.springframework.test.context.ContextConfiguration
import org.springframework.test.context.junit4.rules.SpringClassRule
import org.springframework.test.context.junit4.rules.SpringMethodRule

open class SomeBean {
  open fun sayHello() = "Hello"
}

@Configuration
open class TestConfig {
  @Bean
  open fun someBean(): SomeBean = SomeBean()
}

@ContextConfiguration(classes = arrayOf(TestConfig::class))
open class MyTests(var someBean: SomeBean) : BehaviorSpec() {
  @Rule
  @JvmField
  val springMethodRule: SpringMethodRule = SpringMethodRule()

  companion object {
    @ClassRule
    @JvmField
    val SPRING_CLASS_RULE: SpringClassRule = SpringClassRule()
  }

  init {
    given("A test") {
      `when`("When my test happens") {
        val hello = someBean.sayHello()

        then("Hello should be valid") {
          hello shouldBe "Hello"
        }
      }
    }
  }
}

输出：

另一种尝试：

import io.kotlintest.matchers.shouldBe
import io.kotlintest.specs.BehaviorSpec

import org.junit.ClassRule
import org.junit.Rule

import org.springframework.beans.factory.annotation.Autowired
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration
import org.springframework.test.context.ContextConfiguration
import org.springframework.test.context.junit4.rules.SpringClassRule
import org.springframework.test.context.junit4.rules.SpringMethodRule

open class SomeBean {
  open fun sayHello() = "Hello"
}

@Configuration
open class TestConfig {
  @Bean
  open fun someBean(): SomeBean = SomeBean()
}

@ContextConfiguration(classes = arrayOf(TestConfig::class))
open class MyTests : BehaviorSpec() {
  @Rule
  @JvmField
  val springMethodRule: SpringMethodRule = SpringMethodRule()

  @Autowired
  lateinit var someBean: SomeBean

  companion object {
    @ClassRule
    @JvmField
    val SPRING_CLASS_RULE: SpringClassRule = SpringClassRule()
  }

  init {
    given("A test") {
      `when`("When my test happens") {
          val hello = someBean.sayHello()

      then("Hello should be valid") {
           hello shouldBe "Hello"
        }
      }
    }
  }
}

输出：

这行得通，但是它不使用kotlintest-它仅使用标准JUnit，这不是我想要的：

@ContextConfiguration(classes = arrayOf(TestConfig::class))
class Tests {
  @Rule 
  @JvmField
  val springMethodRule: SpringMethodRule = SpringMethodRule()

  @Autowired
  private lateinit var someBean: SomeBean

  companion object {
    @ClassRule
    @JvmField
    val SPRING_CLASS_RULE: SpringClassRule = SpringClassRule()
  }

  @Test
  fun runTest(): Unit {
    someBean.sayHello() shouldBe "Hello"
  }
}

kotlintest不支持JUnit 4规则。

因此，您根本无法做的事情。

要将Spring的测试支持与JUnit 4SpringRunner结合使用，您必须使用或或SpringClassRule和SpringMethodRule（与Runner支持JUnit 4规则的JUnit 4实现一起）。

另一方面，您可以切换到JUnit 5并使用SpringExtension。许多人似乎发现，使用kotlintest在Kotlin中编写测试要好得多。
