Chromium hangs using the TestCafe Docker image
[Updated] The latest TestCafe version (1.1.4) contains all the necessary flags.You can simplify the browsers property value as follows:
"browsers": "chromium"
Created an issue on the TestCafe GitHub about this. It ended up being resolved by using the --disable-dev-shm-usage flag on Chromium.

PR where this was made a default for running in Docker: https://github.com/DevExpress/testcafe/pull/3557
