没有用Cucumber注入的Spring依赖性。

问题描述 投票：5回答：1

< TL;DR >

问题是：我使用Cucumber-JVM和Spring进行集成测试。 我使用Cucumber-JVM和Spring进行集成测试。测试步骤类中的一个自动布线类没有被创建，是空的。

< TL;DR&gt。

测试在本地工作，但在构建服务器上却失败了，当试图调用autowired bean上的方法时，会出现一个空指针。

堆栈

  • Java 1.8 (本地和构建服务器)
  • Maven 3.3.9 (本地和构建服务器)
  • 本地。Windows 8, Build Server: Ubuntu (无法理解这有什么不同)

我的尝试

问题类被注解为@Component，我试着删除@Component注解并在spring上下文中注册它--这没有任何效果。

将Spring日志级别设置为DEBUG，结果显示的非常少，没有任何问题。对于使用Cucumber runner(@RunWith(Cucumber.class))的测试，我看到Spring的日志相对较少。与使用SpringJunit4Runner的无关测试相比，几乎没有。

我写了一个测试，使用SpringJunit4Runner代替Cucumber runner，并自动连接问题类，工作正常；该类不是空的。

    <bean id="tradeExecutionService" class="com.foo.matching.execution.MockTradeExecutionService"/>

</beans>

这在构建服务器上不工作（在本地很好）。

import org.junit.runner.RunWith;

import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;

@RunWith(Cucumber.class)
@CucumberOptions(plugin = {"pretty", "html:target/cucumber"})
public class MarketOrderTest {

}

public class MarketOrderSteps {

    @Autowired
    private TestHelper testHelper;

    @Given("^The order book looks like this before the trade is placed:$")
    public void setupOrderBook(List<LimitOrder> orders) {
        System.out.println("TestHelper: " + testHelper);
        testHelper.setupOrderBook(orders);
    }

这在构建服务器和本地都能正常工作，让我相信问题出在Cucumber的配置方式上。

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:*Cucumber.xml")
public class SpringTest{

    @Autowired
    private TestHelper testHelper;

    @Test
    public void test() {
        assertNotNull(testHelper);
    }

我讨厌回答自己的问题，但我已经找到了解决方案。

  1. 升级cucumber（所有cucumber info.cukes依赖）到1.2.4。
  2. 添加 @ContextConfiguration("classpath:*Cucumber.xml") 我所有的阶梯防御课程

升级后，我在调试层看到使用Cucumber runner运行的测试有预期的Spring日志量。
