How does detox track the timing of the tests?

[AfonsoGB]

I'm trying to figure out where the timing of each test is allocated. I would like to do something as simple as export those timings.

Take a look at the Timeline Plugin that will produce a JSON artifact that is viewable in Chrome’s tracing view

You can write something like this reporter and register it in your Jest config: https://github.com/jodonnell/jest-slow-test-reporter/blob/master/jest-slow-test-reporter.js

Also take a look at jest-html-reporter which reports the times of test suites and individual tests. It also has the ability to set executionTimeWarningThreshold so that if a test suite is over the limit it appears with red text in the report. Here's how we configured it for Detox.
