Two problematic statements in this article:

1. Test pass rate is 99.98% is not good - the only acceptable rate is 100%.

2. Tests should not be quarantined or disabled. Every flaky test deserves attention.

a test pass rate of 100% is a fairy tale. maybe achievable on toy or dormant projects, but real world applications that make money are a bit more messy than that.

Even something as simple as docker pull fails for 0.02% of the time.

On top of 2., new tests should be stress-tested to make sure they aren't flaky so that the odds of merging them go down.
