dann so meine Funktion

ist

Scenario: Delete requeriment 
    Given the following requeriments: 
     |client|realization|hour|shipping_company|booking|destiny|rtype| 
     |client 1|20/01/2011|08:30|shipping_company 1|booking 1|destiny 1|rtype 1| 
     |client 2|20/01/2011|08:30|shipping_company 2|booking 2|destiny 2|rtype 2| 
     |client 3|20/01/2011|08:30|shipping_company 3|booking 3|destiny 3|rtype 3| 
     |client 4|20/01/2011|08:30|shipping_company 4|booking 4|destiny 4|rtype 4| 
    When I delete the 3rd requeriment 
    Then I should see "La orden de servicio fue eliminada exitosamente" 
    And I should see the following requeriments: 
     |Client|Realization|Hour|Shipping company|Booking|Destiny|Rtype| 
     |client 1|20/01/2011|08:30|shipping_company 1|booking 1|destiny 1|rtype 1| 
     |client 2|20/01/2011|08:30|shipping_company 2|booking 2|destiny 2|rtype 2| 
     |client 4|20/01/2011|08:30|shipping_company 4|booking 4|destiny 4|rtype 4| 

Wenn ich es laufen, bekomme ich diese Fehlermeldung

2 scenarios (1 failed, 1 passed) 
23 steps (1 failed, 2 skipped, 20 passed) 
0m1.263s 

Aber ich habe keine Art mich definiert thod, ich weiß nicht, warum webrat ist triying es

meinen Schritt Definition hier zu nennen, ist

When /^I delete the (\d+)(?:st|nd|rd|th) requeriment$/ do |pos| 
    visit requeriments_path 
    within("table tr:nth-child(#{pos.to_i+1})") do 
    click_link "Destroy" 
    end 
end 

Kann mir jemand helfen?

Answer 1

./app/views/requeriments/show.html.erb Zeile 10 ist, wo der Fehler ist. Haben Sie Single-Table-Vererbung? So riecht das.
