尝试跟踪表中的链接时无法通过 Cucumber 脚本
我正在将 Rails 3 与 Cucumber、Capybara 和 Factory_Girl 一起使用。我正在尝试测试 HTML 表格中某一行的“显示”链接。我正在使用语法：
And I follow "Show" within "Net 30"
我给了我以下错误：
unexpected '30' after 'DESCENDANT_SELECTOR' (Nokogiri::CSS::SyntaxError)
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/racc/parser.rb:99:in `_racc_do_parse_c'
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/racc/parser.rb:99:in `__send__'
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/racc/parser.rb:99:in `do_parse'
./features/step_definitions/web_steps.rb:14:in `with_scope'
./features/step_definitions/web_steps.rb:34:in `/^(?:|I )follow "([^"]*)"(?: within "([^"]*)")?$/'
features/view_payment_terms.feature:10:in `And I follow "Show" within "Net 30"'
这是失败的完整 Cucumber 脚本：
Feature: View Payment Terms
In order to view payment terms
As a user
I want to view payment terms
Scenario: View Payment Terms
Given there is a payment term named "Net 30"
And there is a payment term named "Net 60"
When I go to the "payment terms screen"
And I follow "Show" within "Net 30"
Then I should see "Terms description: Net 30"
如果我将该行更改为只是说：
And I follow "Show"
它通过，没有错误。我查看了水豚附带的 web_steps.rb，我使用的似乎是正确的：
When /^(?:|I )follow "([^"]*)"(?: within "([^"]*)")?$/ do |link, selector|
with_scope(selector) do
click_link(link)
end
end
I am using Rails 3 with Cucumber, Capybara and Factory_Girl. I am trying to test following the "Show" link for just one of the rows on an HTML table. I am using the syntax:
And I follow "Show" within "Net 30"
I gives me the following error:
unexpected '30' after 'DESCENDANT_SELECTOR' (Nokogiri::CSS::SyntaxError)
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/racc/parser.rb:99:in `_racc_do_parse_c'
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/racc/parser.rb:99:in `__send__'
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/racc/parser.rb:99:in `do_parse'
./features/step_definitions/web_steps.rb:14:in `with_scope'
./features/step_definitions/web_steps.rb:34:in `/^(?:|I )follow "([^"]*)"(?: within "([^"]*)")?$/'
features/view_payment_terms.feature:10:in `And I follow "Show" within "Net 30"'
Here is the full Cucumber script that fails:
Feature: View Payment Terms
In order to view payment terms
As a user
I want to view payment terms
Scenario: View Payment Terms
Given there is a payment term named "Net 30"
And there is a payment term named "Net 60"
When I go to the "payment terms screen"
And I follow "Show" within "Net 30"
Then I should see "Terms description: Net 30"
If I change that line to just say:
And I follow "Show"
It passes with no errors. I looked in the web_steps.rb that came with Capybara and what I am using appears to be correct:
When /^(?:|I )follow "([^"]*)"(?: within "([^"]*)")?$/ do |link, selector|
with_scope(selector) do
click_link(link)
end
end

我相信 Cucumber 需要一个有效的 XPath 选择器。尝试编写一个 XPath 查询，该查询将选择包含带有文本“Net 30”的单元格的 TR。此链接可能会有所帮助：xpath 获取表内的行
I believe Cucumber wants a valid XPath selector there. Try writing an XPath query that will select the TR containing a cell with the text "Net 30" in it. This link may help: xpath to get rows inside a table
Nokogiri 在 CSS 选择器
Net 30上抛出错误，因为它当然不是有效的 CSS 选择器。我认为您正在寻找一个文本为“Net 30”的元素，这是非常不同的。Nokogiri is throwing an error at the CSS selector
Net 30because, of course, it's not a valid CSS selector. I think you're looking for an element whose text is "Net 30", which is very different.
