'getByRole' doesn't find a table with a name specified by <caption>

Hello everyone and thanks for the work done. I’m having what i consider an error when trying to locate a <table> with a <caption> inside.

• @testing-library/dom version: “6.16.0”
• Testing Framework and version: – @testing-library/react: “9.5.0”; – @types/jest: “24.9.1”; – with env jest-environment-jsdom-sixteen: “^1.0.3”; – node: v12.16.3

Relevant code or config:

A sample test:

describe('Some problem', () => {
  it('doens\'t considers a <caption> as <table>\'s "name"', () => {
    const { getByRole } = render(
      <table>
        <caption>Monthly savings</caption>
        <thead>
          <tr>
            <th>Month</th>
            <th>Savings</th>
          </tr>
        </thead>
        <tbody>
          <tr>
            <td>January</td>
            <td>$100</td>
          </tr>
        </tbody>
      </table>
    );
    expect(getByRole('table', { name: 'Monthly savings' }))
      .toBeTruthy();
  });
});

  }
}

What I did:

With the configuration and code above, i ran npm test.

What happened:

As output for this specific test, i had:

Unable to find an accessible element with the role "table" and name "Monthly savings"

    Here are the accessible roles:

...

--------------------------------------------------
      table:

      Name "":
      <table />

--------------------------------------------------

...

Reproduction:

This repository reproduces the problem (forked from dom-testing-library-template).

Problem description:

As described in WAI-ARIA Authoring Practices 1.1:

If the table element does not have aria-label or aria-labelledby, then the caption will be used as the accessible name.

Suggested solution:

‘getByRole’ should consider <caption> as name if it exists inside table and “the table element does not have aria-label or aria-labelledby”.

@Tolsee I’ve put up a fix for that since a similar fix was merged yesterday.

@eps1lon Thanks for the insights, I will try to work on the dom-accessibility-api ASAP. I will let you know If I ran into any issues.
