提供超过 1 行的示例 Specflow

Question

当我在一行中提供示例时，它工作正常。当我连续提供多个示例时，我遇到了绑定参数异常。如果我在一行中提供所有示例，那么它不容易阅读。

    Given I get Inputs Folder and list of Files <inputFolder> then <getInputTokens>
    Given I get '<outputDirectory>'
    Given I get directory to save Images '<ImagesOutputDirectory>'

Examples: 
     | inputFolder                                                             | getInputTokens        | outputDirectory                                                                        | ImagesOutputDirectory                                                    |
     | D:\SVN_Projects\XDoc.Net\SpecFlow\Conversion\ConvertToPdf\Inputsfiles | Input1.pdf,Input2.pdf | D:\SVN_Projects\XDoc.Net\SpecFlow\Conversion\ConvertToPdf\AfterConvertingToPdffiles  | D:\SVN_Projects\XDoc.Net\SpecFlow\Conversion\ConvertToPdf\Actualfiles  |
    Given I set saving  Mode <ConversionMode>
    Given I convert pdf using Conversion
    Given I convert to Image '<convertToFile>'
    Then I compare Images '<getActualImagePath>' and '<getExpectedImagePath>' and '<pageCount>'

    | ConversionMode      | convertToFile                                                                         | getActualImagePath                                                      | getExpectedImagePath                                                      | pageCount |

如果示例如下所示，则工作正常：

Examples:
    | inputFolder                                                             | getInputTokens        | outputDirectory                                                                        | ImagesOutputDirectory                                                   | ConversionMode       | convertToFile                                                                          | getActualImagePath | getExpectedImagePath | pageCount |

您的第一个场景存在一些问题。您已将步骤与示例混合在一起。步骤必须在场景大纲中，不能在示例中。

鉴于此，如果您 re-wrote 您的方案包含大纲中的步骤，那么它将如下所示：

Scenario Outline: ConversionUnencrypted Pdf-Pdf
    Given I get Inputs Folder and list of Files <inputFolder> then <getInputTokens>
    Given I get '<outputDirectory>'
    Given I get directory to save Images '<ImagesOutputDirectory>'
    Given I set saving  Mode <ConversionMode>
    Given I convert pdf using Conversion
    Given I convert to Image '<convertToFile>'
    Then I compare Images '<getActualImagePath>' and '<getExpectedImagePath>' and '<pageCount>'
Examples: 
     | inputFolder                                                             | getInputTokens        | outputDirectory                                                                        | ImagesOutputDirectory                                                    |
     | D:\SVN_Projects\XDoc.Net\SpecFlow\Conversion\ConvertToPdf\Inputsfiles | Input1.pdf,Input2.pdf | D:\SVN_Projects\XDoc.Net\SpecFlow\Conversion\ConvertToPdf\AfterConvertingToPdffiles  | D:\SVN_Projects\XDoc.Net\SpecFlow\Conversion\ConvertToPdf\Actualfiles  |
     | ConversionMode      | convertToFile                                                                         | getActualImagePath                                                      | getExpectedImagePath                                                      | pageCount |
     | ConvertToSingleFile | D:\SVN_Projects\XDoc.Net\SpecFlow\Conversion\ConvertToPdf\AfterConvertingToPdffiles | D:\SVN_Projects\XDoc.Net\SpecFlow\Conversion\ConvertToPdf\Actualfiles | D:\SVN_Projects\XDoc.Net\SpecFlow\Conversion\ConvertToPdf\Expectedfiles | 82        |

现在为什么不能在不同的行上有两组示例变得更加明显，因为看起来 inputFolder 的值为 ConversionMode，而实际上 ConversionMode 是标题。

你这里的主要问题是你的例子中有完整的文件路径。这是一个实现细节，恕我直言，最好删除这些路径并改用名字对象。毕竟那些完整的文件路径不会在你的任何其他人的机器上工作，而不是在构建服务器上。我会考虑这样重写它们：

Examples:
    | inputFolder | getInputTokens        | outputDirectory | ImagesOutputDirectory | ConversionMode      | convertToFile | getActualImagePath | getExpectedImagePath | pageCount |
    | 2files      | Input1.pdf,Input2.pdf | 2files          | 2files                | ConvertToSingleFile | 2files        | 2files             | 2files               | 82        |

虽然这有很多重复信息，但现在已经减少了，所以你的整个场景可能是这样的re-written

Scenario Outline: ConversionUnencrypted Pdf-Pdf
    Given I am processing files in the subdirectory <workingFolder> of the input folder then <getInputTokens>
    And I save file to the subdirectory <workingFolder> of the output folder
    And I save Images to the subdirectory <workingFolder> of the images folder
    And I set saving  Mode <ConversionMode>
    And I convert pdf using Conversion
    And I convert to Image the files in the subdirectory <workingFolder> of the output folder
    When I compare Images of page '<pageCount>' in the subdirectory <workingFolder> of the actual image folder and subdirectory <workingFolder> of the expected image folder
    Then the images should be the same 
Examples:
    | workingFolder | getInputTokens        | ConversionMode      | pageCount |
    | 2files        | Input1.pdf,Input2.pdf | ConvertToSingleFile | 82        |

然后您的基础文件夹可以相对于您的项目创建并作为测试构建的一部分进行部署，或者可以保存在配置中。
