How do I test a Rails gem?

What are the best practices for testing a Rails gem?

Best practices include writing unit tests, using RSpec, and ensuring compatibility with different Rails versions.

Can you give me an example of a test for a Rails gem?

Sure! Here's a simple RSpec test:

RSpec.describe MyGem do
  it 'does something useful' do
    expect(MyGem.new.perform).to eq('expected result')
  end
end

How do I run the tests for my gem?

You can run your tests using the command rspec in your terminal from the root directory of your gem.

What should I do if a test fails?

If a test fails, check the error message, debug your code, and ensure your tests are correctly set up.
