What happened?

Test fails with error in the subject.

Exporting export DOCKER_HOST=unix:///Users/kelly/.colima/default/docker.sock fixes the issue.

This doesn't seem like it should be necessary given the documentation here. When I run docker context ls I get:

NAME       DESCRIPTION                               DOCKER ENDPOINT                                   ERROR
