What are RSpec parameters and how do I use them in my tests?

RSpec parameters allow you to pass arguments to your test methods, making them more flexible and reusable.

Can you give me an example of how to define parameters in an RSpec test?

Sure! You can define parameters using the let method or directly in the test method. For example:

RSpec.describe 'MyClass' do
  let(:param) { 'value' }

  it 'does something with param' do
    expect(MyClass.new(param).do_something).to eq('expected_result')
  end
end

What are the benefits of using parameters in RSpec?

Using parameters in RSpec helps to reduce code duplication, improve readability, and allows for more dynamic test cases.

Are there any common pitfalls I should be aware of when using parameters?

Yes, one common pitfall is not resetting the state between tests, which can lead to unexpected results. Always ensure your tests are isolated.
