问题
I'm going through a tutorial that has suggested using rspec, but I have already gone through a lot of default rails installation. I really don't want to have to redo the installation at all. Anyway, when I run
$ rails g integration_test named
I get
invoke test_unit
create test/integration/named_test.rb
When I run bundle, various rspec gems are listed, but test_unit is not. The tutorial seems to have rails invoke rspec instead of test_unit without doing anything additional. How do I get rails to use rspec with the integration test generator command?
回答1:
In your config/application.rb file :
config.generators do |g|
g.test_framework :rspec
end
Now when you run your generators (example rails generate scaffold post), you get rspec test files. Remember to restart your server. For more information on generators see:
RailsCasts #216 Generators in Rails 3
If you really want to use the integration_test generator you'll need to specifically modify the command:
rails g integration_test named --integration-tool=rspec

Working with Rails 3.2.8 and rspec-rails 2.11.4, I discovered that my problem was in my Gemfile. I had rspec-rails in the :test group but not the :development group. Since Rails defaults to running in development mode (including when you're running generate), rspec-rails has to be in your :development group for it to hook into the generators. Once I had that in place, everything worked fine.

As of Rails 3.2.12, follow these steps in order
rails new app_name --skip-test-unit
Add rspec-rails to your Gemfile in the development, test group
group :development, :test do
gem 'rspec-rails'
end
Run bundle install
Run the generator
rails generate rspec:install
... and cleanup your existing test directory:
rm -Rf $RAILS_ROOT/test

To use RSpec instead of default Test::Unit, run following command first
$ rails generate rspec:install
This command will create following folder/files
create .rspec
create spec
create spec/spec_helper.rb
Now whenever you used generator to generate rails components like controller, model etc, it will create corresponding RSpecs.

Came across this issue today. application.rb has to be updated with:
config.generators do |g|
g.test_framework :rspec
g.integration_tool :rspec
end
回答6:
In config/application, add this code
config.generators do |g|
g.test_framework :rspec
g.integration_tool :rspec
end

1. when create new rails app, skip TestUnit framework, or it will generate test_unit directory.
$rails new your_app --skip-test-unit
2. add below code to your_app/config/application.rb file:
config.generators do |g|
g.test_framework :rspec
end
3. add below code to your_app's Gemfile:
group :test, :development do
gem 'rspec-rails'
end
save it, and run bundle install to install rspec gem
4. Initialize the spec/ directory
rails generate rspec:install

What I found that I did that some of the other methods works still is to check my spelling....I had what @tovodeverett had grouping rspec-rails with :development and :test but spelt development incorrectly. That fixed my issue but I was generating tests with test_unit instead of rspec.

$ rails g model Account
invoke active_record
create db/migrate/20140205052617_create_accounts.rb
create app/models/account.rb
invoke test_unit
create test/models/account_test.rb
create test/fixtures/accounts.yml
$ rails d model Account
Running script/rails generate rspec:install does not add rspec as default framework. Added below command in config/application.rb and then it works
config.generators do |g|
g.test_framework :rspec
end
$ rails g model Account
invoke active_record
create db/migrate/20140205052957_create_accounts.rb
create app/models/account.rb
invoke rspec
create spec/models/account_spec.rb
$ rails -v
Rails 4.0.2
