Question

＆LT; TL; DR＆gt;

问题： 我正在使用Cucumber-JVM和Spring进行集成测试。未创建测试步骤类中的自动装配类，并且该类为空。

＆LT; / TL; DR＆gt;

测试在本地工作但在构建服务器上失败，在尝试对自动装配的bean进行方法调用时使用空指针。

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，构建服务器：Ubuntu（无法理解这会产生影响）

我尝试了什么

问题类是带注释的@Component，我尝试删除@Component注释并在spring上下文中注册 - 这没有效果。

将Spring日志级别设置为DEBUG几乎没有任何问题。对于使用Cucumber运行程序（@RunWith（Cucumber.class））的测试，我看到来自Spring的相对较少的日志。与使用SpringJunit4Runner的无关测试相比，几乎没有。

我写了一个测试，它使用SpringJunit4Runner而不是Cucumber跑步者并自动测试问题类，它运行良好;这个班不是空的。

测试中使用的Spring上下文（matching-engine-spring-context-TEST.xml）

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-4.1.xsd">
 <!-- Added this when I removed @Component from its class definition -->
    <bean id="testHelper" class="com.foo.matching.test.common.TestHelper"/>
    <bean id="orderTimeArrivalService" class="com.foo.matching.orderbook.MockOrderArrivalTimeService"/>
    <bean id="tradeExecutionService" class="com.foo.matching.execution.MockTradeExecutionService"/>
    <bean id="orderBookService" class="com.foo.matching.orderbook.TestOrderBookService"/>

</beans>

这在构建服务器上不起作用（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工作正常，这让我相信问题出在Cucumber /我配置它的方式。

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

    @Autowired
    private TestHelper testHelper;

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

Answer 1

我讨厌回答我自己的问题，但我找到了解决方案。

将黄瓜（所有黄瓜信息依赖性）升级到1.2.4
将@ContextConfiguration（＆＃34; classpath：* Cucumber.xml＆＃34;）添加到我的所有步骤def类

在升级之后，我看到在Cucumber运行程序运行的测试中，调试级别的Spring日志记录量是预期的。

没有注入Cucumber
