问题描述

我想在黄瓜页面上写一个数字。请让我知道我该怎么写。

I would like to write a number in cucumber page. Please let me know How can I write this.

方案概述：输入无效的网址

Scenario Outline: Enter an invalid URL

Given the context "Invalid URL" is open on "Market" 
  When user is on the error 404 page
  Then page not found message is displayed

但是我观察到404被作为参数。

But i have observed that 404 is taken as a parameter.

推荐答案

当然，您只需要在步骤定义中将其作为正则表达式（regex）处理即可。您的步骤定义应如下所示：

Sure, you just have to handle it as a regular expression (regex) in your step definitions. Your step definition could read as following:

@When("^When user is on the error \"(\\d+)\" page$")
public void When_user_is_on_the_error_page(int errorNum) throws Throwable {

...

}

可以处理1个或多个数字。 \d代表一个数字，而+号代表 1或更多。

That'll handle 1 or more digits. The \d represents a digit and the + sign represents "1 or more".

我个人喜欢将参数用双引号（）括起来，因为这样IDE理解这是一个参数，可以帮助您完成自动填充等操作。

I personally like wrapping my parameters in double quotes ("") because then the IDE understands it's a parameter and can help you out with autocomplete, etc.

如果您想将其限制为更具体的数字（例如仅三位数字），则可以优化正则表达式到 [\d] {3} 之类的东西。 Oracle在Java正则表达式上提供了经验教训在这里。

If you want to restrict it to more specific numbers (say only three digits) you can refine your regex to something like [\d]{3}. Oracle have lessons on Java regex here.
