quote inside quote for then i should see cucumber prolmem rails

I can clearly see the text in browser.

characters should be "R"开发者_C百科, "P", or "B".

But when I write a step a cucumber step

Then I should see "characters should be \"R\", \"P\", or \"B\"."

It says its

Undefined step: "I should see "characters should be \"R\", \"P\", or \"B\"."" (Cucumber::Undefined)

and says to define the step as

Then /^I should see "([^"]*)"R\\"([^"]*)"P\\"([^"]*)"B\\"([^"]*)"$/ do |arg1, arg2, arg3, arg4|
    pending # express the regexp above with the code you wish you had
end

Why is cucumber not recognizing this step?

Or is it the escaping problem of the quote inside quote?

Thanks

A Pystring might work. Use three doublequotes to indicate an entire line as a string.

Cucumber step

Then I should see
"""

"""

Step definition

Then /^I should see "([^"]*)"$/ do |string|
  pending # express the regexp above with the code you wish you had
end
