如何让 kotlintest 与 Spring 一起工作？
How do get kotlintest to work with Spring?
我正在尝试将 kotlintest 与 Spring 一起使用（不是 Spring Boot，只是标准的 spring-test）。我觉得很难做到。关于我做错了什么的任何指示？我也是 Kotlin 的新手，所以我很可能没有做正确的事情。
这是我到目前为止尝试过的方法：
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：

这行得通，但它没有使用 kotlintest - 它只是使用标准的 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，您尝试做的事情根本不可能。
要使用 Spring 对 JUnit 4 的测试支持，您必须使用 SpringRunner 或 SpringClassRule 和 SpringMethodRule 的组合（使用 JUnit 4 Runner 支持 JUnit 4 规则的实现）。
另一方面，您可以切换到 JUnit 5 并使用 SpringExtension。很多人似乎发现在 Kotlin 中编写测试比使用 kotlintest 更好。
从 KotlinTest 3.0.0 开始，您可以使用 Spring 扩展监听器。
如果您用 @ContextConfiguration.
注释测试 class，这将自动连接 class
例如：
@ContextConfiguration(classes = [(Components::class)])
class UserServiceTest : WordSpec() {
override fun listeners() = listOf(SpringListener)
@Autowired
var service: UserService? = null
init {
"SpringListener" should {
"have autowired the service" {
service!!.repository.findUser().name shouldBe "system_user"
}
}
}
}
您必须将 kotlintest-extensions-spring 依赖项添加到您的构建中。
在上面的代码中，我仅将 SpringListener 添加到单个 class，但您可以通过将其添加到 ProjectConfig.
来在整个项目中使用它
