[nongnu] elpa/dart-mode 25a0b8a 128/192: Add tests for dart-format

[ELPA Syncer]

branch: elpa/dart-mode
commit 25a0b8ae14152fe90b7fd35f000f5903c3a827fd
Author: Brady Trainor <mail@bradyt.com>
Commit: Brady Trainor <mail@bradyt.com>

    Add tests for dart-format
    
    Tests are rudimentary.
    
    Open file test/idempotent.dart, format with C-c C-o, and we find that
    dart-format is not idempotent. After third call dart-format is
    idempotent, in this case.
    
    Open test/breaks.dart, and C-c C-o changes code, not just whitespace.
