我的黄瓜测试失败了，没有填写表格

Question

我对rails非常陌生，甚至更新于BDD。我试图坚持DRY方法，但有些事情不在这里..

FEATURE

  Scenario: Add a new vehicle with valid data
    Given I exist as a user
      And I am logged in
      And I am on the Create New Vehicle page
    When I fill out the form with the following attributes:
      | vehicle_make    | DODGE       |
      | vehicle_model   | RAM 1500    |
      | vehicle_year    | 2005        |
      | vehicle_engine  | 5.7L        |
      | vehicle_color   | Black       |
      And I click the Create Vehicle button
    Then I should see Vehicle was successfully created.

STEP DEFINITION

    ## this is in common_steps.rb

    When /^I fill out the form with the following attributes:$/ do |table|
      puts table.rows_hash
      criteria = table.rows_hash.each do |field, value|
        fill_in field.to_sym, :with => value
      end
    end
    When /^I click the (.*?) button$/ do |button|
      click_button button
    end

测试结果

## seems that its not filling the form out as im getting
## "cannot be blank" validation errors

      ./features/step_definitions/common_steps.rb:48:in `/^I should see (.*?)$/'
      features/vehicles/vehicle_new.feature:23:in `Then I should see Vehicle was successfully created.'

从我能说的一切来看，步骤定义不是填写表单，但是表格值根据结果中的这一行确实存在.. {"vehicle_make"=>"DODGE", "vehicle_model"=>"RAM 1500", "vehicle_year"=>"2005", "vehicle_engine"=>"5.7L", "vehicle_color"=>"Black"}

Answer 1

问题在于以下几行：

fill_in field.to_sym, :with => value

特别是.to_sym导致它没有将正确的值传递给表单字段。删除.to_sym并将其删除：

fill_in field, :with => value

修复了问题，我的测试现在正在通过，同时坚持DRY方法

Answer 2

Scenario: Add a new vehicle with valid data
    Given I exist as a user
    And I am logged in
    And I am on the Create New Vehicle page
    When I fill out the form with the following attributes:
      | attribute_name  | attribute_name | // write attribute name here 
      | vehicle_make    | DODGE          |
      | vehicle_model   | RAM 1500       |
      | vehicle_year    | 2005           |
      | vehicle_engine  | 5.7L           |
      | vehicle_color   | Black          |
    And I click the Create Vehicle button
    Then I should see Vehicle was successfully created.

例如

| name      | display_name | // name and display_name it's a attribute name
| Ollie     | ollie        |
| David     | player       |
| Victoria  | Victoria     |
