我有一个大部分时间都通过的测试：
....
Finished in 1.58 seconds
4 examples, 0 failures
Randomized with seed 29966
但有时会失败：
.F..
Failures:
1) Admin::SessionsController POST create authenticates correct users submissions
Failure/Error: expect(session[:user_id]).to be @user.id
expected #<Fixnum:3> => 1
got #<NilClass:4> => nil
Compared using equal?, which compares object identity,
but expected and actual are not the same object. Use
`expect(actual).to eq(expected)` if you don't care about
object identity in this example.
# ./spec/controllers/admin/sessions_controller_spec.rb:12:in `block (3 levels) in <top (required)>'
Finished in 1.24 seconds
4 examples, 1 failure
Failed examples:
rspec ./spec/controllers/admin/sessions_controller_spec.rb:10
任何人都可以在其中看到任何特定的押韵或原因吗？
规格：
describe "POST create" do
it "authenticates correct users submissions" do
post :create, email: @user.email, password: @user.password
expect(session[:user_id]).to be @user.id
end
it "correctly sets @invalid flag" do
post :create, email: "wrong", password: "wrong"
assigns(:invalid).should be_true
end
end
正在测试的控制器动作：
def create
user = Admin::User.authenticate(params[:email], params[:password])
if user
session[:user_id] = user.id
redirect_to admin_root_path
else
@invalid = true
render :new
end
end
任何帮助将非常感激。让我知道是否需要更多详细信息。
