如何使用最后一个参数的表重用 Cucumber 步骤定义？

Question

这段代码：

Then %{I should see the following data in the "Feeds" data grid:
                                                   |   Name   |
                                                   | #{name}  |}

还有这个：

Then "I should see the following data in the \"Feeds\" data grid:
|   Name   |
| #{name}  |"

还有这个：

  Then "I should see the following data in the \"Feeds\" data grid:\n|   Name   |\n| #{name}  |"

甚至这个：

Then <<EOS
I should see the following data in the "Feeds" data grid:
|   Name   |
| #{name}  |
EOS

给我：

Your block takes 2 arguments, but the Regexp matched 1 argument.

  tests/endtoend/instruments_editor.feature:11:in `And the editor shows "myFeed" in the feeds list

这个：

Then "I should see the following data in the \"Feeds\" data grid: |   Name   || #{name}  |"

这个：

Then "I should see the following data in the \"Feeds\" data grid:|   Name   || #{name}  |"

给我：

Answer 1

我自己找到了答案：

steps %Q{
Then I should see the following data in the "Feeds" data grid:
                                                |   Name   |
                                                | #{name}  |
}

Answer 2

上面的注释：可能看起来很明显，但是第一个“{”之后的新行非常重要

另一种方式：

Given /^My basic step:$/ do |table|
  #do table operation
end


Given /^My referring step:$/ do |table|
  table.hashes.each do |row|    
    row_as_table = %{
      |prop1|prop2|
      |#{row[:prop1]}|#{row[:prop2]}|
    }
    Given %{My basic step:}, Cucumber::Ast::Table.parse(row_as_table, "", 0)
  end
end

Answer 3

你也可以这样写，使用#table

Then /^some other step$/ do
  Then %{I should see the following data in the "Feeds" data grid:}, table(%{
    | Name    |
    | #{name} |
  })
end

Answer 4

考虑使用

Given /^events with:-$/ do |table|
  Given %{I am on the event admin page}
  table.hashes.each do |row|
    Given %{an event with:-}, Cucumber::Ast::Table.new([row]).transpose
  end
end

我发现这比手动构建表格要优雅得多。

事件：- 获取这样的表

| Form | Element | Label |
| foo  | bar     | baz   |

，事件：- 获取这样的表

| Form    | foo |
| Element | bar |
| Label   | baz |
