我正在尝试编写一个测试下载功能的代码,其中需要检查XHR响应是否有“ READY”状态。 我在TestCafe中创建了一个客户端函数,并使用了Promises,但在递归的情况下失败了。
我该如何修复代码以处理这种情况?
P.S. 对于新手问题,请多多包涵,我刚开始自动化测试之旅。
fixture`Download report works`
test
.requestHooks(logger)//connected a request hook, will wait for logger request
('I should be able to download PDF report from header of the page', async t => {
//recursively check if response status is READY, and then go to assertions
const waitForDownloadResponseStatus = ClientFunction((log) => {
return new Promise((resolve,rejects)=>{
const waitForStatus=()=>{
const arrayFromResponse = JSON.parse(log.response.body);
const responseStatus = arrayFromResponse.status;
if (responseStatus == 'READY')
{
resolve(responseStatus);
}
else {
waitForStatus();
}
}
waitForStatus();
})
});
//page objects
const reportTableRaw = Selector('div.contentcontainer').find('a').withText('April 2019').nth(0);
const downloadPdfButton = Selector('a.sr-button.sr-methodbutton.btn-export').withText('PDF');
//actions.
await t
.navigateTo(url)
.useRole(admin)
.click(reportTableRaw)//went to customise your report layout
.click(downloadPdfButton)
.expect(logger.contains(record => record.response.statusCode === 200))
.ok();//checked if there is something in logger
const logResponse = logger.requests[0];
// const arrayFromResponse = JSON.parse(logResponse.response.body);
// const responseStatus = arrayFromResponse.status;
console.log(logger.requests);
await waitForDownloadResponseStatus(logResponse).then((resp)=>{
console.log(resp);
t.expect(resp).eql('READY');
});
});
