Proxy settings for TestCafe: host, port and login

A BooProxies plan gives you four things: a host, a port, a username and a password. These are the values for Residential; the username and password are on your plan page.

The country and the session are chosen in the username, not in a separate setting. The generator on your plan page writes the username for you, and Targeting and sessions explains each part.

TestCafe proxy setup, step by step

1. Add --proxy followed by username:password@host:port.
2. In a configuration file, the same value goes in the proxy property.

TestCafe proxy example

Shell

testcafe chrome tests/ --proxy USERNAME:PASSWORD@resi.proxies.boo:8080

Replace USERNAME and PASSWORD with the login from your plan page. The example asks an IP-check address, so the output is the address your request left from.

Rotating or sticky sessions for TestCafe?

If TestCafe is acting as one visitor through several steps, use a sticky session so the IP address stays the same throughout. If each run is independent, leave the session out and every run starts from a new address.

A sticky username looks like this:

USERNAME-country-us-time-600-session-a1b2c3d4

TestCafe proxy not working?

• Add --proxy-bypass localhost if the site under test runs on your own machine.
• A 407 error means the username or password was not accepted. Copy both again from your plan page, and check that nothing added a space or cut the username short.
• If the IP address is in the wrong country, look at the username: the country code is part of it. More fixes.
