我正在尝试使用ember考试并行运行我的余烬测试。但是,当我运行测试时,我经常遇到浏览器断开问题,并带有以下日志:

我正在运行firefox版本57,版本59更好但是即使在那里我经常看到这个问题,但Chrome似乎表现不错但有时它也失败了。最初我认为它是因为我在无头模式下运行,但即使在非无头模式下,事情也没有好转。我的testem.js文件是:
let today = new Date();
const testWindowWidth = 1920;
const testWindowHeight = 1080;
/**
* Exports configuration to run tests via testem.
* There are issues with running the test in firefox in headless mode.
* Chrome however works fine with the provided configuration.
* @see : https://github.com/testem/testem/issues/1117
* */
module.exports = {
'framework': 'qunit',
'test_page': [
'tests/index.html?hidepassed&nojshint'
],
'disable_watching': true,
'parallel': -1,//sky is the limit
'launch_in_ci': [
'Firefox'
],
'launch_in_dev': [
'Chrome'
],
'browser_args': {
'Firefox': [
`-headless`,//comment this line out for debugging purpose
`-width ${testWindowWidth}`,
`-height ${testWindowHeight}`
],
'Chrome': [
'--headless',//comment this line out for debugging purpose
'--disable-gpu',
'--remote-debugging-port=9222',
'--remote-debugging-address=0.0.0.0',
'--no-sandbox',
'--user-data-dir=/tmp',
`--window-size=${testWindowWidth},${testWindowHeight}`
]
},
'browser_start_timeout': 2 * 60,
'report_file': `tests/logs/${today.getFullYear()}-${today.getMonth() + 1}-${today.getDate()}/${today}.txt`,
'browser_disconnect_timeout': 2 * 60
};
我不知道问题是使用testem配置还是浏览器本身!非常感谢您的帮助/建议。

我无法解决问题,但我能够通过ember-exam避免浏览器断开连接问题。诀窍是弄清楚分区的数量,以拆分测试并且并行地运行它的子集,使得每个ember运行有大约200个测试顶部。我们有相当大的ember应用程序和超过3k的测试,所以我最终创建了shell脚本来管理拆分。
//run-tests.sh
const exec = require('child_process').exec;
var split = 100;//total no of partitions to split the tests into
var parallelRuns = 4;//total no of partitions to run in parallel at a time
var runTestModule = function(partitionNo) {
if (partitionNo > split) {
return;
}
var _partitions = [];
for (var i = 0; i < parallelRuns; i++) {
_partitions.push(++partitionNo);
}
var partitions = _partitions.map(function(index) {
return "--partition=" + index;
}).join(" ");
var command = "./node_modules/.bin/ember exam --path=./dist --split=" + split + " " + partitions + " --parallel";
console.log(
"\n===============================================RUNNING COMMAND===============================================================\n" +
command +
"\n=============================================================================================================================\n");
exec(command, function(e, stdout, stderr) {
if (e instanceof Error) {
console.error(e);
//throw e;
}
console.log('stdout ', stdout);
console.log('stderr ', stderr);
runTestModule(partitionNo);
});
};
runTestModule(0);
