Todd Volkert 1b4f817b0c Make tests more hermetic. (#8765) ... 1. Add `PortScanner` abstraction so that we don't do actual port scanning in tests. 2. Don't change the real `cwd` of the isolate during tests, as it affects all tests, not just the current running test. Fixes #8761		2017-03-14 10:28:56 -07:00
