Is there a way to tell tests are running in parallel on a single machine?

[quad5]

I am running Cypress in a Docker via Jenkins. Judging from the total time the whole run took, I don't think it was running in parallel.

I am using the following dependencies:

"chai": "4.2.0",
"chai-string": "^1.5.0",
"cypress-file-upload": "5.0.5",
"cypress-grep": "2.13.1",
"cypress-localstorage-commands": "1.7.0",
"cypress-terminal-report": "^2.2.0",
"deepmerge": "^4.2.2",
"lodash": "^4.17.21",
"lodash.clonedeep": "4.5.0",
"mocha": "8.2.1",
"mochawesome": "7.1.3",
"path": "^0.12.7",
"uuid": "^8.3.0"
