Cucumber (Java) 通过 Windows 命令行通过批处理工作，但不是 pom

Question

我正在 Windows 命令行上浏览 Cucumber For Java 书中的示例。我可以从 Windows 批处理文件中很好地执行它，但是当尝试从 Maven 执行它时，我得到“没有要编译的源代码”和“没有要运行的测试”。 pom 中需要什么来指向与批处理中相同的类/功能？

Feature: Checkout
    Scenario: Checkout a banana
        Given the price of a "banana" is 40c
        When I checkout 1 "banana"
        Then the total price should be 40c
    Scenario Outline: Checkout bananas
        Given the price of a "banana" is 40c
        When I checkout <count> "banana"
        Then the total price should be <total>c
        Examples:
        | count | total |
        | 1     | 40    |
        | 2     | 80    |
    Scenario: Two bananas scanned separately
        Given the price of a "banana" is 40c
        When I checkout 1 "banana"
        And I checkout 1 "banana"
        Then the total price should be 80c
    Scenario: A banana and an apple
        Given the price of a "banana" is 40c
        When I checkout 1 "banana"
        And I checkout 1 "apple"
        Then the total price should be 65c

Answer 1

在 Maven 中使用 cucumber-jvm 时，项目需要遵守 Maven 约定，以便 cucumber-jvm 可以获取不同的文件。如果使用maven-surefire-plugin：

• 特征文件需要存放在src/test/resources；
• 步骤定义需要存放在src/test/java；
• 带有@RunWith(Cucumber.class) 注释的单元测试需要存储在src/test/java 中。

然后可以运行mvn test 执行测试。你可以看看this example我已经放到github了。
