I'm new to rails testing,i want to test my rails controller api. I using gems rails-rspec , capybara and database-cleaner like this in my Gemfile:
group :development, :test do
gem 'rspec-rails', '~> 3.7'
end
group :test do
gem 'database_cleaner'
gem 'capybara'
end
And in my spec folder i create a controller and create a user_controller_spec.rb inside my api folder and want to test create a user with valid parameters and write a code like this:
RSpec.describe "API V1 Users", type: 'request' do
describe "POST /api/v1/users" do
context "with valid parameters" do
let(:valid_params) do
{
fname: "Riya",
lname: "******",
email: "*******.com",
password: "",
contact: "2144333",
country_code:"91",
address: "Sector 63",
city: "Noida",
state: "UP",
country: "India",
zipcode: "23001",
role: "***",
image: ""
}
end
it "creates a new user" do
expect { post "/api/v1/users", params: valid_params}
expect(response).to have_http_status(:ok) # it's use for code 200
end
it "creates a user with the correct attributes" do
post "/api/v1/users", params: valid_params
expect(User.last).to have_attributes valid_params
end
end
context "with invalid parameters" do
# testing for validation failures is just as important!
# ...
end
end
end
But it gives me error :
Failure/Error: expect(User.last).to have_attributes valid_params expected nil to respond to :fname, :lname, :email, :password, :contact
To be sure that your post query create an user you can write it like this:
expect { post "/api/v1/users", params: valid_params}.to change(User, :count).by(1)
It test if a user is added to the database.
