<p>This test checks that by default, if using JavaScript to focus an element triggers <code>:focus-visible</code> matching, then the element should show a focus ring with <code>outline-style: auto</code>.</p>
<ol id="instructions">
<li>If the element below that says "Target" show a focus ring with <code>outline-style: auto</code>, then the test result is SUCCESS.</li>
</ol>
<p id="warning">Your user-agent does not support <code>:focus-visible</code> pseudo-class, please SKIP this test.</p>
<div id="target" tabindex="0">Target</div>
<script>
// Check that :focus-visible is supported.
test_valid_selector(':focus-visible');
async_test(function(t) {
target.addEventListener("focus", t.step_func(function() {
assert_equals(getComputedStyle(target).outlineStyle, "auto", `outline-style for ${target.tagName}#${target.id} should be auto`);
t.done();
}));
target.focus();
}, "By default initial programatic focus matches ':focus-visible', so the element shows a focus ring with 'outline-style: auto'");
