无法通过水豚测试Devise [英] Failing to test Devise with Capybara
问题描述
我正在使用Devise构建一个Rails 3应用程序，并通过Capybara进行UI测试。以下测试失败：
I'm building a Rails 3 app using Devise, with Capybara for UI testing. The following test is failing:
class AuthenticationTest < ActionController::IntegrationTest
def setup
@user = User.create!(:email => 'test@example.com',
:password => 'testtest',
:password_confirmation => 'testtest')
@user.save!
Capybara.reset_sessions!
end
test "sign_in" do
# this proves the user exists in the database ...
assert_equal 1, User.count
assert_equal 'test@example.com', User.first.email
# ... but we still can't log in ...
visit '/users/sign_in'
assert page.has_content?('Sign in')
fill_in :user_email, :with => 'test@example.com'
fill_in :user_password, :with => 'testtest'
click_button('user_submit')
# ... because this test fails
assert page.has_content?('Signed in successfully.')
end
end
...但是我不知道为什么。从代码中可以看到，正在数据库中创建用户。我使用的方法与Seeds.rb中创建用户的方法相同。
... but I have no idea why. As you can see from the code, the user is being created in the database; I'm using the same approach to create the user as I did in seeds.rb.
如果通过调试器运行测试，则可以看到数据库中的用户并验证页面是否正在加载。但是认证仍然失败。我可以验证这一点，因为如果我更改断言以测试失败案例，则测试通过：
If I run the test through the debugger, I can see the user in the database and verify that the page is loading. But still the authentication fails; I can verify this because if I change the assertion to test for the failure case, the test passes:
# verify that the authentication actually failed
assert page.has_content?('Invalid email or password.')
I我习惯了Rails 2，使用Selenium进行这种测试，所以我怀疑我在做些愚蠢的事情。有人可以向我指出正确的方向吗？
I'm used to Rails 2, & using Selenium for this sort of testing, so I suspect I'm doing something daft. Could someone please point me in the right direction here?
推荐答案
我遇到了同样的问题，并发现了具有解决方案的线程：
I was having the same issue and found a thread with a solution:
RSpec.configure do |config|
config.use_transactional_fixtures = false
config.before(:suite) do
DatabaseCleaner.strategy = :truncation
end
config.before(:each) do
DatabaseCleaner.start
end
config.after(:each) do
DatabaseCleaner.clean
end
end
要使DatabaseCleaner起作用，您需要包括 database_cleaner gem。如果您以前从未使用过它，则可能需要 rake db：test：prepare 才能重新运行测试。我希望这也对您有用！
For the DatabaseCleaner stuff to work you'll need to include the database_cleaner gem. If you haven't used it before, you may need to rake db:test:prepare before rerunning your tests. I hope this works for you, too!
