how to ignore a line in `dart-lang/coverage`

Question

use case

codecov sees super as in need for test,

not sure being sure if writing a test for this keyword

• would be meaningful
• how to write such a test

I'd like to exclude the line from coverage until my doubts are cleared

question

how do I ignore a line in dart-lang/coverage

Solution 1

at the moment is not possible

to exclude a line for code coverage in dart and flutter (see this issue)

I'm disambiguating the question about what is the correct way to test super keyword

Solution 2

I see this. Not perfect, but a solution

// coverage:ignore-line to ignore one line.
// coverage:ignore-start and // coverage:ignore-end to ignore range of lines inclusive.
// coverage:ignore-file to ignore the whole file.

Solution 3

In documentation for widget_tester.dart

testWidgets('MyWidget asserts invalid bounds', (WidgetTester tester) async {
  await tester.pumpWidget(MyWidget(-1));
  expect(tester.takeException(), isAssertionError); // or isNull, as appropriate.
});

Make 2 tests 1 for begin null (expect begin is null) and 1 for end null (expect end is null)

thanks, but what about super? [editing the question] also... it's not a widget

A lot people are saying it was fixed, but I'm on the latest version of Flutter and it still doesn't appear to be fixed. I can ignore a whole file, but I cannot ignore sections of a file.
