Proposal: remove --lint flag from ng test #4114
Description
Currently ng test offers the option of linting in addition to running unit tests.
This is sounds like a desirable feature since it is surely better to get both linting and testing feedback continuously via a single command.
The reality, however, is that doing both at the same in anything but a toy project time is slow.
The purpose of running unit tests in a watch loop is to get very fast feedback on your changes, thus anything that slows it down is a problem.
When not running in watch mode, it would be just as easy to do ng test --single-run --lint as it is to do ng test --single-run && ng lint.
Additionally, different linting setups are used in each command which can lead different results/presentation.
Thus I argue that the linting flag in ng test should be removed because it is a 'trap', in the sense that it is only useful in trivial scenarios.
