避免在小黄瓜中重复自己

Question

所以我一直在使用specflow一段时间,而且一直在困扰我.

这是我们当前使用的场景的示例:

Scenario: Select a region via selection button
    When I select "Scotland" from Available Regions
    And I click on the "Select One" button
    Then Available Regions does not contain "Scotland"
    And Selected Regions contains "Scotland"

是否有一个避免在几乎每一行都说"苏格兰"？或者它是否使它更具可读性,我应该坚持下去？

Answer 1

在我尝试回答你的问题之前,我是否可以建议你花一点时间去阅读Dan North's Who的域名无论如何.

首先,我想摆脱所说的那条线And I click on the "Select One" button,因为我认为这应该是隐含的一部分When I select "Scotland" from Available regions.

现在你有了

Scenario: Select a region 
    When I select "Scotland" from Available Regions
    Then Available Regions does not contain "Scotland"
    And Selected Regions contains "Scotland"

你可以把它写成

Scenario: Select a region 
    When I select "Scotland" from Available Regions
    Then Available Regions does not contain the last selected region
    And Selected Regions contains the last selected region

有什么区别吗？好吧可能不是.

我发现,因为我花了更多的时间在黄瓜上,因为它有助于重构你的场景,就像你重构它们背后的代码一样.在C#/ SpecFlow中我们可以实现

    Then Available Regions does not contain "Scotland"

同

    [Then("Available Regions does not contain (.*)")]
    public void ThenAvailableRegionsDoesNotContain(string region)
    {
        AvailableRegions.Contains(region).ShouldBeFalse();
    }

和

    Then Available Regions does not contain the last selected region

同

    [Then("Available Regions does not contain the last selected region")]
    public void ThenAvailableRegionsDoesNotContainLastSelectedRegion()
    {
        ThenAvailableRegionsDoesNotContain(LastSelectedRegion);
    }

老实说,这取决于你.你更喜欢哪种方言
