v2.0.0

Major Changes

• #345 847cbd8 Thanks @calebeby! - Normalize whitespace in getAccessibilityTree

  Now anytime there is contiguous whitespace in text strings it is collapsed into a single space. This matches the behavior of browser accessibility trees.

  This is a breaking change because it changes the getAccessibilityTree output, and may break your snapshots. Update your snapshots with Jest and review the changes.

• #446 1eaa648 Thanks @calebeby! - Use document.title as fallback implicit accessible name for html root element in accessibility tree snapshots

• #445 5fa4103 Thanks @calebeby! - Add heading levels to getAccessibilityTree. The heading levels are computed from the corresponding element number in <h1> - <h6>, or from the aria-level role.

  In the accessibility tree snapshot, it looks like this:

  heading "Name of Heading" (level=2)
  

  This is a breaking change because it will cause existing accessibility tree snapshots to fail which contain headings. Update the snapshots to make them pass again.

• #451 eb364cc Thanks @calebeby! - Added aria-expanded support to getAccessibilityTree and fix handling for <details>/<summary>

  Now, elements which have the aria-expanded attribute will represent the state of that attribute in accessibility tree snapshots. <details>/<summary> elements will represent their expanded state in the tree as well.

  Also, for collapsed <details>/<summary> elements, the hidden content is now hidden in the accessibility tree, to match screen reader behavior.

• #248 abe22a6 Thanks @gerardo-rodriguez! - Enforce minimum target size when calling user.click(), per WCAG Success Criterion 2.5.5 Target Size guideline.

Minor Changes
