Maven：@ParameterizedTest 上没有可运行的方法

Question

我有一个参数化测试，在运行 IntelliJ 运行测试配置时正常通过。

但是运行ning mvn test 抛出 java.lang.Exception: No runnable methods.

标有 @Test 的所有其他非参数化测试通常双向通过，但由于此参数化测试，我的构建失败。

我将不胜感激:)

测试：

import org.junit.jupiter.api.Assertions.*
import org.junit.jupiter.params.ParameterizedTest
import org.junit.jupiter.params.provider.Arguments
import org.junit.jupiter.params.provider.MethodSource

internal class SampleTest {
    @ParameterizedTest
    @MethodSource("samples")
    fun `should pass` (actual: String, expected: String) {
        // test body
    }

    companion object {
        @JvmStatic
        fun samples() = listOf(
            Arguments.of("actual", "expected")
        )
    }
}

mvn test的错误：

我的 POM 依赖项：

       <dependency>
            <groupId>org.jetbrains.kotlin</groupId>
            <artifactId>kotlin-test-junit</artifactId>
            <version>${kotlin.version}</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-api</artifactId>
            <version>RELEASE</version>
            <scope>test</scope>
        </dependency>
        <dependency>

            <version>5.4.2</version>
            <scope>test</scope>
        </dependency>

并构建插件：

          <plugin>
                <groupId>org.jetbrains.kotlin</groupId>
                <artifactId>kotlin-maven-plugin</artifactId>

                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <jvmTarget>1.8</jvmTarget>
                </configuration>
            </plugin>

Answer 1

遗憾的是我无法重现您的问题，但以下几点可能对您有所帮助：

使用最新的surefire插件。将以下内容添加到 pom

中的 build/plugins

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <version>3.0.0-M3</version>
</plugin>

将 jupiter 引擎添加到 pom 中的依赖项

<dependency>
  <groupId>org.junit.jupiter</groupId>
  <artifactId>junit-jupiter-engine</artifactId>
  <version>RELEASE</version>
  <scope>test</scope>
</dependency>

您已将 junit-jupiter-api 添加为依赖项 3 次，这可能是复制粘贴错误。
