ruby-on-rails - 为什么这个带有 post 请求的集成测试失败了？

Question

我已经为写入两个表/模型的注册表单编写了集成测试。它失败并显示消息 "Organization.count"didn't change by 1。但是，有没有一种方法可以查看测试失败的错误消息类型(该表单在开发中有效，尽管显示错误消息存在问题，所以我不明白测试失败的原因)。所以我的意思是，如果您在服务器上做了同样的事情，您会看到错误消息，以帮助我找出它没有保存组织/用户的原因。

  test "valid combined organization user signup" do
    get new_path
    assert_template 'organizations/new'
    assert_difference ['Organization.count', 'User.count'], 1 do
      post organizations_path, organization: { name: "Abc1",
                                               bag: "aef1",
                            users_attributes: [email: "test@test.br",
                                               username: "abc1",
                                               password: "foobar",
                                               password_confirmation: "foobar"] }
       end
  end

也许测试日志可以提供帮助？我在这里看到用户电子邮件和用户名的 IS NULL LIMIT。鉴于测试语法，我不明白为什么...

Controller 方法发布在这里:stackoverflow.com/q/31072646/4499505 (organizations_path指的是create方法)

如果我将测试日志与开发日志进行比较(因为在开发中表单确实有效)，对于开发，它会在下面发布帖子，这似乎与测试日志中的帖子不同。我应该如何调整测试语法以创建与开发中相同的帖子？

Parameters: {"utf8"=>"✓", "authenticity_token"=>"***", "organization"=>{"name"=>"test60", "bag"=>"tes60", "users_attributes"=>{"0"=>{"email"=>"test60@example.com", "username"=>"test60", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}}}, "commit"=>"Register"}

更新:为了匹配开发日志，我将测试中的 post 行更改为:

post organizations_path, organization: { name: "Abc def 1",
                                         bag: "adef1",
             users_attributes: { "0" => {email: "adef1@uniqu.br",
                                         username: "adef1",
                                         password: "foobar",
                                         password_confirmation: "foobar"}} }
end

现在在测试日志中它不再有 IS NULL LIMIT 但它仍然回滚因此测试仍然失败并显示相同的消息:

  [1m[35mSQL (0.5ms)[0m  INSERT INTO "organizations" ("name", "bag", "created_at", "updated_at") VALUES ($1, $2, $3, $4) RETURNING "id"  [["name", "Abc def 1"], ["bag", "adef1"], ["created_at", "2015-06-27 19:49:45.430750"], ["updated_at", "2015-06-27 19:49:45.430750"]]
  [1m[36mUser Exists (0.4ms)[0m  [1mSELECT  1 AS one FROM "users" WHERE LOWER("users"."email") = LOWER('adef1@uniqu.br') LIMIT 1[0m
  [1m[35m (0.5ms)[0m  SELECT "users"."email" FROM "users"  ORDER BY "users"."username" ASC
  [1m[36mUser Exists (0.5ms)[0m  [1mSELECT  1 AS one FROM "users" WHERE LOWER("users"."username") = LOWER('adef1') LIMIT 1[0m
  [1m[35m (0.2ms)[0m  ROLLBACK TO SAVEPOINT active_record_1

您的测试代码与您的开发代码不一样。您需要在 users_attributes 数组中添加方括号:

test "valid combined organization user signup" do
  get new_path
  assert_template 'organizations/new'
  assert_difference ['Organization.count', 'User.count'], 1 do
    post organizations_path, 
         organization: { name: "Abc1",
                         bag: "aef1",
                         users_attributes: { "0" => { email: "test@test.br",
                                                      username: "abc1",
                                                      password: "foobar",
                                                      password_confirmation: "foobar" } } }
  end
end

这就是为什么您的日志说它正在尝试查找 email IS NULL 的用户，因为它无法检索 email code> 属性正确，所以它只是默认为 NULL 而不是 test@test.br。

编辑:更新以匹配工作语法。 OP 还报告说，一旦语法得到修复，User 模型就会出现错误，没有通过 username 的最小长度验证，他通过简单地使用更长的用户名来修复在测试数据中。
