These tests were very simple before and now this should result
in more code coverage without affecting test performance.
The only tricky thing was testing the `--missing` option without
actually installing a package using `install_test_formula` because
that is very slow (around 10 seconds on my machine). I ended
up just writing the tab to a plausible keg directory for each
package I wanted to "install". This allows us to test the behavior
while also not increasing CI time by ~20 seconds (though it'd
probably be faster on CI than my local machine).
- Extract update tests into separate tests.
- Make `brew tests --online` run only once in its own job. This job
could be made non-required to fight flakiness.
- Split up the various macOS runs into several steps now that we have
more parallel macOS workers available.
- Cleanup some flaky tests.
We added the `--all` flag (now renamed to `--eval-all`) for various
commands for this behaviour so let's start deprecating this.
Also, introduce a `HOMEBREW_EVAL_ALL` environment variable to use the
existing, less secure, behaviour by default and avoid passing
`--eval-all` everywhere.
Due to limitations of the test framework, this only tests
that the command with the --debug-symbols
flag succeeds and that on MacOS the `dsymutil` is run.
On MacOS, the compile flags `-g` are not set, and I can't figure out
how to set them here. `dsymutil` runs successfully regardless of if
there are debug symbols or not.
Same on linux therefore the test cannot succeed.
But only checks that the command works. Not that `dsymutil` is called
or that `-g` is added to the compile args.
(Not sure how to do either in an integration test.)
From reading https://github.com/orgs/Homebrew/discussions/3328: I
initially thought we should just change "Updated" to "Modified" when
appropriate. After conversation with Bo98, though, I thought more and
saw that we're already checking for outdated formulae here so, rather
than ever traverse through the formula history, look at the outdated
formula and list them unless we've set
`HOMEBREW_UPDATE_REPORT_ALL_FORMULAE` in which case we show the
modifications.
While we're here, also do a bit of reformatting and renaming to better
clarify intent.
