java - 在cucumber特征文件中仅执行一次@Given

Question

我想在 cucumber 中测试以下功能。但是，我只想处理输入文件一次(以下功能中的@Given)。但是，它似乎每次都执行@Given 步骤。是否可以在以下功能中仅执行一次此@Given？

@fileValidation

Scenario Outline: File Validation

Given a file is uploaded with name "something.csv"
Then response filename created should not match input filename "something.csv"
And reason for errors should be "<Reason>" with error code "<Error code>" for row with RequestId "<RequestId>"

Examples:

  | RequestId     |  Error code | Reason |     
  | 123           |   101       | Failure 1 |
  | 124           |   102       | Failure 1; Failure 2 |

我还通过删除给定步骤尝试了 Before 和 After Hook ，但没有成功。

我也在钩子(Hook)之前尝试过，但示例中的每一行仍然进入此循环。

  @Before("@fileValidation")
    public void file_is_uploaded() throws Throwable {
        String fileName = "something.csv";
        processInputFile(fileName);
    }

    @After("@fileValidation")
    public void clear() {
        outputFileName = null;
    }

在功能文件中我有这样的内容:

@fileValidation
Scenario Outline: File Validation

Background: Read the uploaded file "something.csv"
Then response filename created should not match input filename "something.csv"
And reason for errors should be "<Reason>" with error code "<Error code>" for row with RequestId "<RequestId>"

Examples:

  | RequestId     |  Error code | Reason |     
  | 123           |   101       | Failure 1 |
  | 124           |   102       | Failure 1; Failure 2 |

在每个场景集或场景大纲之前运行一些步骤(后台)也可以通过创建标记的@Before方法并将Scenario对象作为参数传递来实现。在 before 方法中，仅当场景名称与上一个场景不同时才执行逻辑。

以下是具体操作方法:

Feature:Setup Data Given Customer logs in as System Admin

@BeforeMethodName
Scenario Outline: Verify ......... 1 
    When <Variable1> And <Variable2> 
    Then <Variable3>

Examples:
    | Variable1 | Variable2 | Variable3 |
    | A1            | B1          | C1        |
    | A2            | B2          | C2        |
    | A3        | B3          | C3        |
    | A4        | B4          | C4        |


@BeforeMethodName
Scenario Outline: Verify ......... 2 
    When <Variable1> And <Variable2> 
    Then <Variable3>

Examples:
    | Variable1 | Variable2 | Variable3 |
    | X1            | Y1          | Z1        |
    | X2            | Y2          | Z2        |
    | X3        | Y3          | Z3        |
    | X4        | Y4          | Z4        |

并定义@BeforeMethodName如下:

private static String scenarioName;

public className BeforeMethodName(Scenario scene) {

        if(!scene.getName().equals(scenarioName)) {

//            Implement your logic

        scenarioName = scene.getName()

        }

        return this;
    }

这样，BeforeMethodName 将在每个场景之前被调用，但每个场景大纲仅执行一次逻辑。
