Launch chrome with debug logs on console

@uraikwar were you able to figure it out?

Hi @jginsburgn,

Yes, I figured it out.

Karma launches the browser as a subprocess and consumes its input and output/err stream. So, technically there is no hook is provided that we can use to print the browser's debug log in the console without modifying the karma's code.

One of the good options could be to print the browser's debug log in a file instead of the console. This can be done by setting an environment variable CHROME_LOG_FILE for the file location.

process.env['CHROME_LOG_FILE'] = '/opt/chrome/chrome_debug.log'; // or by setting the env at OS level before running Karma.

and launcher config looks like this:

defaultConfig.customLaunchers["ChromeWithLogs"] = {
       base: "Chrome",
       flags: ["--enable-logging=stderr", "--v=1"]
 };
