在this example之后，我试图在JUnit 5中运行cucumber测试，但@Suite不喜欢我：

org.junit.platform.suite.engine.NoTestsDiscoveredException: Suite [org.ono.sprint.demo.CucumberRunnerTest] did not discover any tests

字符串
我花了一天的时间来研究它，如果有人能给我给予正确的提示，我会非常感激。这似乎是一个JUnit级别的问题，因为它甚至不识别测试类。
测试设置有一个空的@Suite，@SpringBootTest类，它似乎是由 cucumber 特定的注解配置的。

package org.ono.sprint.demo;

import io.cucumber.spring.CucumberContextConfiguration;
import org.junit.platform.suite.api.ConfigurationParameter;
import org.junit.platform.suite.api.IncludeEngines;
import org.junit.platform.suite.api.SelectClasspathResource;
import org.junit.platform.suite.api.Suite;
import org.springframework.boot.test.context.SpringBootTest;

import static io.cucumber.junit.platform.engine.Constants.GLUE_PROPERTY_NAME;

@Suite
@IncludeEngines("cucumber")
@SelectClasspathResource("features")
@ConfigurationParameter(key = GLUE_PROPERTY_NAME, value = "org.ono.sprint.demo")
@CucumberContextConfiguration
@SpringBootTest
public class CucumberRunnerTest {
}

.来做cucumber step definitions类中描述的实际测试，它附带了一个功能文件。我不认为这是一个cucumber问题在这个阶段，所以我省略了功能文件）：

package org.ono.sprint.demo;

import org.junit.jupiter.api.Assertions;

import org.springframework.boot.test.web.server.LocalServerPort;
import org.springframework.web.client.RestTemplate;

import io.cucumber.java.en.When;

public class StepDefinitionsTest {

  @LocalServerPort
  private int port;

  private final RestTemplate restTemplate = new RestTemplate();

  @When("I request a greeting")
  public void i_request_a_greeting() {
    String greetingUrl = "http://localhost:" + port + "/greetings";

    String greeting = restTemplate.getForObject(greetingUrl, String.class);
    Assertions.assertEquals("Hello", greeting);
  }

}

另外，实际的Sping Boot 实现非常琐碎，因此省略。
