我需要增加此超时时间:
COMMAND |命令`test`在[32.585s]之后以错误结束 命令| BackstopExcpetion:未定义的测试#1:GotoTimeoutError:goto()timeout
请考虑以下服务器代码:
const http = require('http');
const hostname = '0.0.0.0';
const port = 3000;
http.createServer((req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/html');
res.end(`<!DOCTYPE html>
<title>Test Page</title>
<script>console.log("Hello world!")</script>
<h1>Hello world!</h1>
`);
}).listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});
和带有4 * 3 = 12次测试的BackstopJS配置:
{
"id": "backstop_default",
"viewports": [
{ "label": "phone_portrait", "width": 320, "height": 480 },
{ "label": "phone_landscape", "width": 480, "height": 320 },

],

{ "label": "Test #3", "url": "http://localhost:3000/", "selectors": ["body"] }
],

"ci_report": "backstop_data/ci_report"
},
"report": ["browser"],
"engine": "chrome",
"engineFlags": []
}
当我开始backstop test
时,一切正常:

但现在让我们在发送页面之前让服务器延迟40秒:
const http = require('http');
const hostname = '0.0.0.0';
const port = 3000;
http.createServer((req, res) => {
setTimeout(() => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/html');
res.end(`<!DOCTYPE html>
<title>Test Page</title>
<script>console.log("Hello world!")</script>
<h1>Hello world!</h1>
`);
}, 40000);
}).listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});
并运行backstop test
:
D:\Temp\Supertemp\server-delay>backstop test

如您所见,出现错误
COMMAND |命令`test`在[32.585s]之后以错误结束 命令| BackstopExcpetion:未定义的测试#1:GotoTimeoutError:goto()timeout
但之后我们可以在页面上看到console.log
。 Backstop开始无限期等待......无论如何,这不是问题。
我有兴趣选择放大30秒超时,因为在某些情况下,开发服务器需要更多时间来提供内容。我该如何配置?
答案 0 :(得分:2)
在an onBeforeScript
中,您可以在发出任何请求之前访问Chromy并设置超时(以及other options):
module.exports = function (chromy) {
chromy.options.gotoTimeout = 60000;
};
答案 1 :(得分:0)
您可以通过添加engineOptions属性来传递backstop.json中的任何chromy选项,如下所示
{
"engineOptions": {
"gotoTimeout": 60000
}
}
