ruby-on-rails - cucumber + Selenium 随机失败

Question

我的 selenium 测试喜欢随机失败。作为一个例子，我有这个场景

Scenario: I should be able to edit a user
  Given I created a user with the login "test@example.com"
  And I am viewing the user with login "test@example.com"
  Then I should see "Edit this user"
  When I click "Edit this user"
  Then I should be editing the user with login "test@example.com"
  When I press "Update"
  Then I should be viewing the user with login "test@example.com"
  And I should see "User was successfully updated."

这和其他的一起，使用基本的 webrat :rails 模式工作得很好。在 Selenium 中，线

Then I should be editing the user with login "test@example.com"

和

Then I should be viewing the user with login "test@example.com"

随机失败，因为有时第一个失败，其他时候第二个失败。手动使用网站会导致正确操作，正如我所说，webrat/rails 模式工作正常。

rails 2.2.2 cucumber 0.3.7selenium 1.1.14(固定用于 FF3)

一些额外的信息:

Scenario: I should be able to edit a user                         # features/admin_priviledges.feature:26
  Given I created a user with the login "test@example.com"        # features/step_definitions/global_steps.rb:18
  And I am viewing the user with login "test@example.com"         # features/step_definitions/global_steps.rb:60
  Then I should see "Edit this user"                              # features/step_definitions/webrat_steps.rb:93
  When I click "Edit this user"                                   # features/step_definitions/webrat_steps.rb:18
  Then I should be editing the user with login "test@example.com" # features/step_definitions/global_steps.rb:66
    expected: "/users/8/edit",
         got: "/users/8" (using ==)
    Diff:

    features/admin_priviledges.feature:31:in `Then I should be editing the user with login "test@example.com"'
  When I press "Update"                                           # features/step_definitions/webrat_steps.rb:14
  Then I should be viewing the user with login "test@example.com" # features/step_definitions/global_steps.rb:66
  And I should see "User was successfully updated." 

Then /^I should be (editing|viewing) the (\w+) with (\w+) "([^\"]*)"$/ do |action,model,field,value|
  func = make_func(action,model)
  m = find_model_by_field_and_value(model,field,value)
  URI.parse(current_url).path.should == eval("#{func}(m)")
end

这些是相关步骤。按“更新”是一个标准的 webrat 步骤(点击按钮)

Answer 1

从

更改 webrat 步骤

When /^I press "([^\"]*)"$/ do |button|
  click_button(button)
end

到

When /^I press "([^\"]*)"$/ do |button|
  click_button(button)
  selenium.wait_for_page_to_load
end

它有效。让 selenium 等待修复!
