rspec-rails VS factory_bot_rails

I am very comfortable with Minitest in Ruby. When I started to learn Rails, though, I was surprised by how different RSpec was. In case .NET testing is equally unlike the xUnit style, I should learn the idioms.

It supports both RSpec and Minitest as well as any other testing gem. There are flexible configurations options which allow to configure editor with needed testing tool.

I'm a huge supporter for TDD(Test Driven Development). Almost every piece code should be tested. During my co-op more than half of the time I spent writing test for my PR. I believe that experience really helped me understand the necessity of testing. I was surprised to see how similar the testing framework in JS and Ruby are. I used Jest which is very similar to RSpec I have used during my co-op. To mock http resquest I used Nock kinda similar to something called VCR.

The describe and it keywords are popularly used in other JavaScript testing frameworks to write and organize unit tests. This style originated in Ruby's Rspec testing library and is commonly known as spec-style testing.

5. Automated Tests: Unit tests are automated tests that verify the behavior of a small unit of code in isolation. I like to write unit tests for every bug reported by a user. This way, I can reproduce the bug in a controlled environment and verify that the fix works as expected and that we wont see a regression. There are many different JavaScript test frameworks like Jest, cypress, mocha, and jasmine. We use Rspec and Minitest for unit and integration tests in our rails application.

When it comes to testing code, both frameworks are very much comparable since you can test either using the versatile RSpec library.

When starting a Rails project, you have a lot of decisions to make. Whether or not to write tests should not be one of them. The big decision is to use Minitest or Rspec. Both of those testing frameworks are great and provide everything you need to test a Rails application thoroughly.

RSpec

Ruby testing with RSpec

Finally, before writing and running any tests, you'll likely need to install another gem to define test data for your Rails app: FactoryBot.

While we’re at it, let's add a couple of other gems we’ll need for our test environment: factory_bot_rails is a fixtures replacement and generates test model instances. faker is handy for generating fake strings of data to be used in tests. Add those gems to the development and test group of your Gemfile:

Factory Bot Rails

rspec-rails factory_bot_rails faker

Hey all, just published a simple gem to mass generate FactoryBot factories for existing projects. Someone had this issue on GitHub (https://github.com/thoughtbot/factory_bot_rails/issues/404). I failed to build it in a nice way within the main gem, but wanted to get a solution out there for people who might be in need. I had to get some legacy codebases up to speed in the past, and this would have been useful. Cheers! https://github.com/FanaHOVA/factory_bot_rails_seeder

I use FactoryBot for creating the factory, for stubbing the factory. My factory is containing an image that has to be uploaded and attached as doc every time a factory created:

Here is some real Gherkin from the Factory Bot Rails gem source code on GitHub:

If your are using gems like faker , factory_bot_rails and database_cleaner to create and clean test records then creating unnecessary records can cost you time and speed.
