Ho avuto questo problema esatto per mesi, attraverso più versioni di ciascun componente coinvolto (karma, socket.io, salsa-connect). Attualmente sto lavorando su Karma 12.16.karma-sauce-launcher disconnette ogni sessione di test risultante in esecuzioni fallite con IE e Safari
Fondamentalmente, quando si utilizza https://github.com/karma-runner/karma-sauce-launcher, i browser Safari e IE hanno avviato la disconnessione di ogni singola esecuzione di test con conseguente esecuzione di test parziale. Il registro Karma rilevante è

ho cercato aumentando browserNoActivityTimeout a 60000, ma che appena si traduce nelle prove in mancanza, dopo 60 anni invece di 10s. Ognuno di questi fallito ha il seguente:

A seconda del browser, a volte si eseguirà solo 50 test (eseguito 50 di 94 scollegato), e su altri è eseguirà tutti i test, ma ancora essere considerato un test fallito. Non ho mai visto questo si verifica con Chrome o Firefox.
Lo stesso file karma.conf verrà eseguito ogni volta localmente senza problemi. Qualcuno ha incontrato questo? Ho raggiunto il supporto di saucelabs, ma stanno iniziando a insistere sul fatto che si tratta di un problema di lancio di karma-salsa.
Karma.conf:
var fs = require('fs');
module.exports = function(config) {
// Use ENV vars on Travis and sauce.json locally to get credentials
if (!process.env.SAUCE_USERNAME) {
if (!fs.existsSync('sauce.json')) {
console.log('Create a sauce.json with your credentials based on the sauce-sample.json file.');
process.exit(1);
} else {
process.env.SAUCE_USERNAME = require('./../sauce').username;
process.env.SAUCE_ACCESS_KEY = require('./../sauce').accessKey;
}
}
