<title>CSS Test (Selectors): Mouse focus does not show a focus ring by default</title>

<p>This test checks that by default, using the mouse to focus a generic element does not show a focus ring (because it does not trigger <code>:focus-visible</code> matching).</p>
<ol id="instructions">
<li>Click on the element below that says "Click me."</li>
<li>If the element does not have a focus ring, 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">Click me.</div>
<script>
setup({ explicit_done: true });
// Check that :focus-visible is supported.

async_test(function(t) {
target.addEventListener("focus", t.step_func(function() {
assert_equals(getComputedStyle(target).outlineStyle, "none", `outline-style for ${target.tagName}#${target.id} should be none`);
t.done();
}));
test_driver.click(target).then(() => done());
}, "Mouse focus does not show a focus ring by default");
