Addresses https://github.com/microsoft/playwright/issues/31863. This PR
is chonky, but the individual commits should be easy to review. If
they're not, i'm happy to break them out into individual PRs.
There's two main things this does:
1. Remove some unused imports
2. Add a `clsx`-inspired helper function for classname templating
I wasn't able to replace `ReactDOM.render` with `ReactDOM.createRoot`.
This is the new recommended way starting with React 18, and the existing
one is going to be deprecated at some point. But it somehow breaks our
tests, i'll have to investigate that separately.
#19576 introduced a regression where the CLI reporters displayed some
times with way too many decimals. e.g. 7.123456789ms.
Prior to #19576, there were two monotonicTime implementations; that PR
updated the reporters to use the common definition that had existed in
utils.ts. However, that introduced a regression in the base.ts reporters
which used the ms duration humanizing package which did not account for
the more precise decimals used by the shared monotonicTime function.
This fix removes the dependency on the third-party ms package and now
consistently uses Pavel's humanize function which the HTML reporter had
been using and proved to have better defaults for decimals.
Additionally, we add more test coverage to limit future regressions
since this was caught in passing.
Closes#19556.
Relates #19576.
