不能打的DB，通過集成測試與MINITEST

Question

我不斷收到測試f

「User.count」沒有通過1

改變，即使我不應該（因爲SessionsController＃create已經可以工作了）。

測試代碼是這樣的：

- [重構/更新] - 我也下車在模型中的所有驗證，只是爲了看看......但沒有

class UsersSignupTest < ActionDispatch::IntegrationTest 

    test "valid signup information" do 

    OmniAuth.config.test_mode = false 

    get signup_path 
    assert_difference 'User.count', 1 do 
     get '/auth/identity/register', params: { 
     user: { name: "Example User", 
       email: "user@example.com", 
       password_digest: "password", 
       identities: { user_id: 1, 
           provider: "identity", 
           uid: "1"}}} 
    end 

    OmniAuth.config.test_mode = true 
    end 
end 

的全輸出：

UsersSignupTest#test_valid_signup_information = 0.69 s = F 


Failure: 
UsersSignupTest#test_valid_signup_information [/home/lsoave/rails5/gitwatcher/test/integration/users_signup_test.rb:19]: 
"User.count" didn't change by 1. 
Expected: 5 
    Actual: 4 

與tail -f log/test.log我得到如下：

更新注意：

真正的模型用戶的has_many標識/身份belong_to用戶的關係，我不知道它是正確的表示：

... 
params: { 
      user: { name: "Example User", 
        email: "user@example.com", 
        password_digest: "password", 
        identities: { user_id: 1, 
            provider: "identity", 
            uid: "1"}}} 
... 

Answer 1

嘗試更換身份：一塊類似於：

identities_attributes: { '0': {provider: "identity", uid: "1"}} 

and ch埃克您的用戶模型包含：

accepts_nested_attributes_for :identities 

無需處理自己與分配USER_ID的相關模型，這就是Rails是擅長。
