在黄瓜功能文件中仅执行一次@Given [英] Execute @Given only once in cucumber feature file

问题描述

我要在黄瓜中测试以下功能。但是，我只想处理输入文件一次（以下功能中的@Given）。但是，似乎每次都执行@Given步骤。只能在以下功能中执行一次@Given吗？

I have the following feature that I would like to test in cucumber. But, I would like to process the input file only once ( @Given in the below feature ). But, it seems to be executing the @Given step each time. Is it possible to execute this @Given in the following feature only once?

@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 |

我也尝试了前和后钩子，没有运气就删除了给定步骤。

I also tried Before and After hooks by removing Given step with no luck.

我也在钩子之前尝试过，但对于示例中的每一行，它仍然会循环到此循环。

I also tried before hooks, still it is coming to this loop for each row in the examples.

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

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

在功能文件中我有类似以下内容：

and in the feature file I have something like this:

@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 |

推荐答案

运行一些步骤（背景），也可以通过创建带有 tagged的@Before 方法并将Scenario对象作为参数来实现每个情景集或情景大纲之前。在before方法中，仅当方案名称与上一个方案不同时才执行逻辑。

Running some steps (Background) before each set of scenarios or a Scenario Outline can also be achieved by creating a tagged @Before method and passing a Scenario object as parameter. Within the before method, execute your logic only if the scenario name is different as compared to the last scenario.

下面是操作方法：

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        |

并按如下所示定义@BeforeMethodName：

And define the @BeforeMethodName as below:

private static String scenarioName;

public className BeforeMethodName(Scenario scene) {

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

//            Implement your logic

        scenarioName = scene.getName()

        }

        return this;
    }

这样，在每种情况之前都会调用BeforeMethodName，但是只会执行一次逻辑每个方案大纲。

This way BeforeMethodName will be called before each scenario but will execute the logic only once per Scenario Outline.
