• render(<App />): virtual DOM
• screen.*: select element(s) from the V/ DOM
• fireEvent: event handling

most importantly, a big take from here will be about ARIA(Accessible Rich Internet Applications)

• screen.getByRole W3C Role Definitions
• expect.toHaveStyle
• expect.toBeEnabled, expect.toBeDisabled
• expect.not.toBeChecked

• when a function is used in multiple files
• when a function has too many edge cases
• describe > can have multiple test functions inside

1. Test interactivity using fireEvent

2. jest-dom assertions:

   • toBeEnabled()
   • toBeDisabled()
   • toBeChecked()

3. getByRole option { name: }

4. Jest describe to group tests

5. Unit testing functions - a function in a component is too complicated so you don't want to render it multiple times (theoratically)
