An example of an AI chatbot conversation about testing view helpers in applications.
How do I test view helpers in my application?
To test view helpers, you can use a testing framework like RSpec or Minitest. Start by creating test cases that check the output of your helpers with various inputs.
Can you give me an example of a test case for a view helper?
Sure! If you have a helper method that formats dates, you could write a test like this: expect(format_date(Date.new(2023, 1, 1))).to eq('January 1, 2023').
What if my helper method has dependencies?
In that case, you can use mocks or stubs to isolate the helper method from its dependencies during testing.
How do I run the tests after writing them?
You can run your tests using the command line. For RSpec, use rspec and for Minitest, use ruby -Itest test_helper.rb.
