[英]How to Test Api In Rails Rspec
I'm new to rails testing,i want to test my rails controller api. 我是Rails测试的新手,我想测试我的Rails Controller API。 I using gems rails-rspec , capybara and database-cleaner like this in my Gemfile: 我在我的Gemfile中使用了gems rails-rspec , capybara和database-cleaner :
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: 在我的spec文件夹中,我创建一个控制器,并在api文件夹中创建一个user_controller_spec.rb,并想要测试使用有效参数创建用户并编写如下代码:
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 : 但这给了我错误:
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: 为确保您的帖子查询创建了一个用户,您可以这样编写:
expect { post "/api/v1/users", params: valid_params}.to change(User, :count).by(1)
It test if a user is added to the database. 它测试是否将用户添加到数据库中。
