npm test fails with timeout

[v-andrew]

To reproduce, run the following commands:

• git clone https://github.com/strongloop/loopback4-example-shopping
• cd loopback4-example-shopping
• npm install
• npm test

It fails with:

> lb-mocha --allow-console-logs "packages/*/dist/__tests__/**/*.js"

  !

Hi Andrew
Do you have Docker installed?

EDIT: I've just updated docker and I'm now getting the following error on win10:

lb-mocha --allow-console-logs "packages/*/dist/__tests__/**/*.js"

  !

  0 passing (30s)
  1 failing
  1) "before all" hook in "{root}":
     Error: Timeout of 30000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.

@raymondfeng Hi Raymond, I'm getting the same error below on Win 10 and Ubuntu 19. Do you have any ideas?

Experiencing the same error.

I'm using MacOS, and it seems to be working fine for me. @hacksparrow, since you're actively working on this repo, do you have some insights on this? Thanks.

Hard to tell without a Windows machine.

Hard to tell without a Windows machine.

@hacksparrow Is there anything I can run on Win 10/Ubuntu to give useful diag. info?
If it helps... https://developer.microsoft.com/en-us/windows/downloads/virtual-machines

@v-andrew I think Error: connect ENOENT //./pipe/docker_engine typically means docker is not running. This projects' test requires Docker to be installed and the service running.

[raymondfeng]

It requires a docker engine to be running on the Windows machine.

[dougal83]

Resolved Ubuntu issue, not sure what was wrong but tests now run correctly. Have completely rebuilt VM with 4Gb RAM instead of 2Gb.

[Riplar]

It would be good to document and/or update the README.md because the installation instructions do not say anything about Docker. I myself never used Docker and I have no idea what I have to do to get this working.

[dougal83]

Working on Win 10 via WSL remote console on VSCode.

Doesn't work with Docker running

For now, using WSL or linux VM are viable options.
