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
colima * colima unix:///Users/kelly/.colima/default/docker.sock
default Current DOCKER_HOST based configuration unix:///var/run/docker.sock
