| This test checks that programmatically focusing an element after a keypress causes <code>:focus-visible</code> to match. |
| <ol id="instructions"> |
| <li>Use the tab key to move focus to the button below that says "Tab to me and press ENTER."</li> |
| <li>Press ENTER.</li> |
| <li>If the element that says "I will be focused programmatically." has a red background, then the test result is FAILURE. If the element has a green outline, then the test result is SUCCESS.</li> |
| </ol> |
| <br /> |
| <button id="button">Tab to me and press ENTER.</button> |
| <div id="el" tabindex="-1">I will be focused programmatically.</el> |
| <script> |
| button.addEventListener("click", () => { |
| el.focus(); |
| }); |
| async_test(function(t) { |
| el.addEventListener("focus", t.step_func(function() { |
| assert_equals(getComputedStyle(el).outlineColor, "rgb(0, 100, 0)"); |
| t.done(); |
| })); |
| el.focus(); |
| }, "Programmatic focus after keypress should match :focus-visible"); |
