* Unskip integration tests on Windows that now pass
The referenced issue is closed and these tests pass for me locally on Windows now.
* Remove import that's no longer used
* Add another issue that is afffecting these tests on Windows
* Add a hot restart test and mark skip on Windows
Skipped due to https://github.com/flutter/flutter/issues/21348.
All temporary directory start with `flutter_` and have their random component separated from the name by a period, as in `flutter_test_bundle.YFYQMY`.
I've tried to find some of the places where we didn't cleanly delete temporary directories, too. This greatly reduces, though it does not entirely eliminate, the directories we leave behind when running tests, especially `flutter_tools` tests.
While I was at it I standardized on `tempDir` as the variable name for temporary directories, since it was the most common, removing occurrences of `temp` and `tmp`, among others.
Also I factored out some common code that used to catch exceptions that happen on Windows, and made more places use that pattern.
* Upgrade everything except matcher.
* Roll matcher (and test)
* Adjust tests that depend on flutter:test directly to depend on a shim
* Require use of package:test shim and remove other references to package:test
* Skip tests instead of expecting failure, because expected failure = timeout which is slow
Some of these tests are known to fail and were coded to expect it; however because the failure is a timeout it's just dragging out test runs (shortening timeouts will make the tests flakier).
* Make it easier to find skipped tests
* Change SKIP to TODO
* Skip integration tests that use flutter-tester on Windows
This is known to be broken. I will un-skip all of these once a fix for flutter-tester lands on Windows.
* Save with added import!
* Add tests to ensure flutter run does not quit at startup
These tests require https://github.com/dart-lang/vm_service_client/pull/38 to be merged and currently the third test (pause-on-exceptions) fails because of a bug.
* Remove TODO
Probably makes most sense this way for now.
* Address PR comments
