compact display is only compact for wide terminal windows

[skybrian]

When I run the protobuf tests, it looks like it doesn't clear the line properly when the window isn't wide enough to display the filename and test name together. (I use fairly long test names, so perhaps that triggers this effect.)

Example output:

With a wide window:

$ pub run test
00:01 +33: All tests passed!                                                                       
skybrian@skybrian5:~/dart/work/dart-protobuf
$ 

With a normal sized window:

$ pub run test
00:00 +0: loading test/readonly_message_test.dart             00:01 +0: loading test/coded_buffer_reader_test.dart          00:01 +0: test/readonly_message_test.dart: can write a read-on00:01 +1: test/readonly_message_test.dart: can write a read-on00:01 +2: test/json_test.dart: testWriteToJson                00:01 +3: test/json_test.dart: testWriteToJson                00:01 +4: test/json_test.dart: testWriteToJson                00:01 +5: test/json_test.dart: testWriteToJson                00:01 +6: test/json_test.dart: testWriteToJson                00:01 +7: test/json_test.dart: testWriteToJson                00:01 +8: test/json_test.dart: testWriteToJson                00:01 +9: test/json_test.dart: testWriteToJson                00:01 +10: test/json_test.dart: testWriteToJson               00:01 +11: test/json_test.dart: testWriteToJson               00:01 +12: test/reserved_names_test.dart: GeneratedMessage res00:01 +13: test/coded_buffer_reader_test.dart: testCodedBuffer00:01 +14: test/coded_buffer_reader_test.dart: testCodedBuffer00:01 +15: test/coded_buffer_reader_test.dart: testCodedBuffer00:01 +16: test/coded_buffer_reader_test.dart: testCodedBuffer00:01 +17: test/coded_buffer_reader_test.dart: testCodedBuffer00:01 +18: test/coded_buffer_reader_test.dart: testCodedBuffer00:01 +19: test/coded_buffer_reader_test.dart: testCodedBuffer00:01 +20: test/coded_buffer_reader_test.dart: testCodedBuffer00:01 +21: test/coded_buffer_reader_test.dart: testCodedBuffer00:01 +22: test/coded_buffer_reader_test.dart: testCodedBuffer00:01 +23: test/coded_buffer_reader_test.dart: testCodedBuffer00:01 +24: test/coded_buffer_reader_test.dart: testCodedBuffer00:01 +25: test/codec_test.dart: testFloat                    00:01 +26: test/codec_test.dart: testFloat                    00:01 +27: test/codec_test.dart: testFloat                    00:01 +28: test/codec_test.dart: testFloat                    00:01 +29: test/codec_test.dart: testFloat                    00:01 +30: test/codec_test.dart: testFloat                    00:01 +31: test/codec_test.dart: testFloat                    00:01 +31: test/codec_test.dart: testDouble                   00:01 +32: test/codec_test.dart: testDouble                   00:01 +32: test/codec_test.dart: testVarint                   00:01 +33: test/codec_test.dart: testVarint                   00:01 +33: All tests passed!

(It's actually displayed better than that in the terminal window; each output line is on a separate line but they're all flush left.)

This is using GNOME Terminal 3.6.2, but I think it was similar on my Mac. (I didn't realize that it was a bug and was trying to figure out why some tests were being printed but not others.)

There are a long chain of blocked issues that mean the test runner can't use stdout.terminalColumns to detect how wide your terminal is, so it just limits its line width to 100 characters. If your terminal isn't 100 characters wide, you see effects like this. The best workaround at the moment is to either make your terminal wider or use -r expanded.
