示例1: test
test('Base tag emulation should not leak to other imports', async () => {
const {ast: doc} = await bundle('base.html');
const clickMe = dom5.query(doc, preds.hasTextValue('CLICK ME'));
assert.ok(clickMe);
// The base target from `test/html/imports/base.html` should apply to
// the anchor tag in it.
assert.equal(dom5.getAttribute(clickMe!, 'target'), 'foo-frame');
const doNotClickMe =
dom5.query(doc, preds.hasTextValue('DO NOT CLICK ME'));

// to the anchor tag in `test/html/imports/base-foo/sub-base.html`
