新手问题 Ruby on Rails tutorial，遇到的问题？
def setup
@user = users(:little)
end
test "login with valid information" do
get login_path
post login_path, params: { session: { email: @user.email,
password: 'password' } }
assert_redirected_to @user
follow_redirect!
assert_template 'users/show'
assert_select "a[href=?]", login_path, count: 0
assert_select "a[href=?]", logout_path, count: 1
assert_select "a[href=?]", user_path(@user), count: 1
end
def setup
@user = User.first
end
test "login with valid information" do
get login_path
post login_path, params: { session: { email: @user.email,
password: '111111' } }
assert_redirected_to @user
follow_redirect!
assert_template 'users/show'
assert_select "a[href=?]", login_path, count: 0
assert_select "a[href=?]", logout_path, count: 1
assert_select "a[href=?]", user_path(@user), count: 1
end
第一个是书上给的，第二个是我改了之后的，第二个测试无法通过，说是希望重定向，结果得到的是成功，但是把正确的密码'111111'改成'password' 测试竟然神奇的可以通过，书上说约定固件的密码为'password',应该和这没关系吧？为啥啊？
Failure: UsersLoginTest#test_login_with_valid_information [/home/yirolhao/ruby/project/rails/my-first-app/test/integration/users_login_test.rb:35]: Expected response to be a <3XX: redirect>, but was a <200: OK>
逻辑上来说，密码不对怎么会让你登录并重定向到 user 界面？
另外，你确定 User.first 与 users(:little) 是同一个？
user = User.find_by(email: params[:session][:email].downcase)
if user && user.authenticate(params[:session][:password])
log_in user
redirect_to user
else
flash.now[:danger] = 'Invalid email/password combination'
render 'new'
end
暂时看，是测试环境下，你修改的 User.first 仍然取到了 fixture 里的 little 用户
然后用 111111 测试，返回了成功，但这个是 http 请求成功，就是说此时密码错误了
