[英]Geckodriver/Firefox issue when running Robot Framework Selenium tests inside Docker container
[英]Firefox browser disconnect issue when running tests via testem
我正在嘗試使用余燼考試並行運行余燼測試。 但是,當我運行測試時,經常出現瀏覽器斷開連接問題,並顯示以下日志:

我正在運行firefox版本57,版本59更好,但即使在那兒我也經常看到此問題,但是chrome的運行情況似乎不錯,但有時也會失敗。 最初我以為是因為我在無頭模式下運行,但是即使在無頭模式下,情況也不會變得更好。 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
};
我不知道問題出在testem配置還是瀏覽器本身! 謝謝您的幫助/建議。
我無法解決問題,但可以通過ember-exam避免瀏覽器斷開連接問題。 訣竅是找出分區的數目以划分測試並僅並行運行其中的一個子集,這樣每個余燼運行最多可以進行200個測試。 我們有相當大的余燼應用程序,可以進行超過3k的測試,因此我最終創建了shell腳本來管理拆分。
//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);
