示例1: function
QUnit.test("HTML tags re-rendered", function(assert) {
let template = compile("<h1>hello!</h1><div>content</div>");
let result = render(template, {});
env.begin();
result.rerender();
env.commit();
assert.equal(serializer.serializeChildren(root), "<h1>hello!</h1><div>content</div>");
});示例2: TestEnvironment
QUnit.test('ensure commit cleans up when it can', assert => {
let env = new TestEnvironment();
env.begin();
// ghetto stub
Object.defineProperty(env, 'transaction', {
get() {
return {
scheduledInstallManagers() : void { },
commit() : void {
throw new Error('something failed');
}
};
}
});
assert.throws(() => env.commit(), 'something failed'); // commit failed
// but a previous commit failing, does not cause a future transaction to fail to start
env.begin();
