我正在尝试从此处进行示例集成测试:https://guides.emberjs.com/release/testing/testing-components/(测试操作)
我的问题是,由于某种原因,“测试”输出会不断自动刷新?
测试代码:
this.paginator.length=mock.length;
Component.js:
locationManager.showsBackgroundLocationIndicator = true
组件模板:
test('Can handle submit action', async function (assert) {
/*
* THIS TEST HAS PROBLEMS
* THE PAGE CONSTANTLY REFRESHES FOR THIS TEST, NO IDEA WHY, NEED TO INVESTIGATE
*/
assert.expect(1);
// test double for the external action
this.set('externalAction', (actual) => {
const expected = {inputValue: 'test'};
assert.deepEqual(actual, expected, 'submitted value is passed to external action');
});
await render(hbs`{{user-form inputValue="test" saveAction=(action externalAction)}}`);
// click the button to submit the form
await click('#submitButton');
});
我认为这可能是因为模板中的表单一直在提交,但事实并非如此,因为它只应单击一次提交。任何帮助,不胜感激!

在@Lux的建议后写为评论;您需要执行以下操作来防止表单提交重新加载页面:
save(inputValue, event) {
event.preventDefault()
if (this.inputIsValid) {
this.saveAction(inputValue); // pass action handling to route that uses component
}
}
您收到event
作为最后一个参数,并调用preventDefault
告诉浏览器不要像通常那样处理事件。有关详细说明,请参见MDN。
