I want to test controller's action and flash messages presence with rspec.
action:
def create user = Users::User.find_by_email(params[:email]) if user user.send_reset_password_instructions flash[:success] = "Reset password instructions have been sent to #{user.email}." else flash[:alert] = "Can't find user with this email: #{params[:email]}" end redirect_to root_path end spec:
describe "#create" do it "sends reset password instructions if user exists" do post :create, email: "[email protected]" expect(response).to redirect_to(root_path) expect(flash[:success]).to be_present end ... But I've got an error:
Failure/Error: expect(flash[:success]).to be_present expected `nil.present?` to return true, got false

To run a single Rspec test file, you can do: rspec spec/models/your_spec. rb to run the tests in the your_spec. rb file.
They are stored in the sessions cookie on the user's browser in order to persist for the next request. For the request following that one the flash hash clears itself out. They are not stored in the session cookie. They are merely associated with the session cookie.
RSpec is a testing tool for Ruby, created for behavior-driven development (BDD). It is the most frequently used testing library for Ruby in production applications. Even though it has a very rich and powerful DSL (domain-specific language), at its core it is a simple tool which you can start using rather quickly.
RSpec is a computer domain-specific language (DSL) (particular application domain) testing tool written in the programming language Ruby to test Ruby code. It is a behavior-driven development (BDD) framework which is extensively used in production applications.
You are testing for the presence of flash[:success], but in your controller you are using flash[:notice]

The best way to test flash messages is provided by the shoulda gem.
Here are three examples:
expect(controller).to set_flash expect(controller).to set_flash[:success] expect(controller).to set_flash[:alert].to(/are not valid/).now If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
