How To Test

Tests should reflect added min/max props and corresponding aria values.
To test the value manually, run storybook (yarn storybook) and try out the different sliders with the developer tools --> Element open. You should see aria-min and aria-max values. When moving the slider, you should see the aria-valuenow changing.

Hey this looks good - all the elements are there and thanks for adding storybook at well.

Would you mind exploring a small code change and adding another test case for when the consumer does pass in their own aria- attributes?

This would be in addition to the test already there. The way the code is written right now we would ignore those props if they passed them in. We usually want to handle cases where users are passing in props - described more here

Test cases I would love to see:

• "handles custom aria- attributes if passed in"
• "if default value is not present, uses midpoint between min and max as aria-valuenow"

I've added tests.
I'm getting this warning with tests, though not sure how to resolve (or why it's complaining):
Warning: Invalid ARIA attribute ariaValueNow. Did you mean aria-valuenow? at RangeInput.tsx line 21

@kimallen Thanks for calling out those React warnings. They were caused by not using snake case aria-valuenow on the test case for "renders aria values" in RangeInput.test.tsx.

Fixing that caused the test to start failing. Also started seeing type errors in RangeInput. That's because aria attributes are an exception to camelcase everything rule in React. Forgot about that 😄. So made more changes in RangeInput.tsx to refer to the aria- attributes in lowercase snake-case.

Also added another step to our aria test to check that keyboard actions are actually updating the aria-valuenow.

Looks good, I think we can merge!
