关于功能测试、BDD 和 TDD 的困惑

我有一张表格，其中必须填写多个字段。但是，只有一个字段是必填的。所以，我提出了以下规范：

 [Subject(typeof(CompanyHomeController))]
public class when_the_save_button_is_clicked
{
    private It should_verify_that_the_company_name_has_been_filled;

    private It should_show_some_text_next_to_the_company_field_if_it_has_not_been_filled;

    private It should_submit_all_the_details_on_the_form_if_there_are_no_errors;

    private It should_take_the_user_back_to_the_list_of_companies;
}

现在我想实现这个，但我很困惑，因为它听起来非常像功能测试，我必须使用 mvccontrib.watin dll 之类的东西。我说得对吗，这确实是功能测试？我是否为 BDD 制定了“错误”的规范？

原文

I have a form where several fields have to be filled in. However, only one field is compulsory. So, I came up with the following spec:

 [Subject(typeof(CompanyHomeController))]
public class when_the_save_button_is_clicked
{
    private It should_verify_that_the_company_name_has_been_filled;

    private It should_show_some_text_next_to_the_company_field_if_it_has_not_been_filled;

    private It should_submit_all_the_details_on_the_form_if_there_are_no_errors;

    private It should_take_the_user_back_to_the_list_of_companies;
}

Now I'd like to implement this but I'm getting confused because it sounds very much like functional testing where I'd have to use something like the mvccontrib.watin dlls. Am I right that it's indeed functional testing? Have I formulated the specs "wrong" for BDD?

我还不太担心这些定义 - 各种形式的测试和测试之间存在很多模糊的界限。无论如何，BDD。

WRT Watin，我猜你是在谈论通过浏览器进行测试？您可以通过浏览器进行测试或直接在控制器上进行“皮下”测试，这两种方法都是执行 BDD 的有效方法。这种选择更多地取决于您要测试的内容、您希望测试运行的速度等等。

就您的规格而言，我可以看到它们实施起来可能有点棘手。您可能希望对有效/无效提交有不同的规范，例如：（

[Subject(typeof(CompanyHomeController))]
public class company_form_submitted_with_fields_completed
{
    It should_save_all_the_details_to_the_main_list;

    It should_take_the_user_back_to_the_company_list_page;
}

[Subject(typeof(CompanyHomeController))]
public class company_form_submitted_with_some_fields_missing
{
    It should_remain_on_the_company_edit_page;

    It should_warn_that_the_company_field_is_required;
}

请注意，您不需要“私有”修饰符，这会稍微清理一下）。

I wouldn't worry too much about the definitions just yet - there are a lot of blurred boundaries between the various forms of testing & BDD anyway.

WRT Watin, I guess you're talking about testing via the browser? You can test via the browser or 'subcutaneously' directly on your controllers, both are valid ways of doing BDD. That choice is more down to what you're trying to test, how fast you want your tests to run, and so on.

In terms of your specs, I can see they might be a little tricky to implement. You probably want to have different specs for valid/invalid submissions, e.g.:

[Subject(typeof(CompanyHomeController))]
public class company_form_submitted_with_fields_completed
{
    It should_save_all_the_details_to_the_main_list;

    It should_take_the_user_back_to_the_company_list_page;
}

[Subject(typeof(CompanyHomeController))]
public class company_form_submitted_with_some_fields_missing
{
    It should_remain_on_the_company_edit_page;

    It should_warn_that_the_company_field_is_required;
}

(notice you don't need the 'private' modifiers, which cleans it up a bit).
