Using USE_NET_HOST takes 2½ minutes and returns an error code

[schlomo]

I want to point the selenium tests at a service running on my local machine, therefore I start Zalenium with the USE_NET_HOST=true environment variable set. That way running my selenium tests works well.

The problem is that

1. it takes 2½ minutes to start Zalenium
2. the return code to the shell is 4 and not 0, indicating an error while it actually works.

Here is the output:

It's a bug in the one-liner script, I can recreate.

Thanks for finding this! I will mark it to fix later.

In the meantime you can use -i for interactive mode ... bash -s start -i

[elgalu]

Should be fixed now!

Thanks a lot, now it is down to 10 seconds and a clean exit code. Thank you very much for the quick fix!
