'Load custom HTML on browser tests
I'm trying to write a test on browser (Chrome) with a custom HTML file. I followed the instructions and here is what I have:
test/
|- web_test.dart
|- web_test.html
// test/web_test.dart
@TestOn('browser')
import 'dart:html' as html;
import 'package:flutter_test/flutter_test.dart';
void main() {
test('It should load the custom html file', () {
expect(html.document.title, 'Custom HTML file title');
});
}
<!-- web_test.html -->
<!doctype html>
<html>
<head>
<title>Custom HTML file title</title>
<link rel="x-dart-test" href="web_test.dart">
<script src="packages/test/dart.js"></script>
</head>
</html>
Then I run
flutter test --platform chrome
It looks like the custom html file is not used:
Logs:
00:02 +0 -1: It should load the custom html file [E]
Expected: 'Custom HTML file title'
Actual: 'web_test.dart Test'
Which: is different.
Expected: Custom HTM ...
Actual: web_test.d ...

What am I missing?
The code is available in this repository.
Solution 1:[1]
Unfortunately, it seems to not be supported. The package test is meant to be run with dart test and not flutter test. See this issue.
In it, they suggest writing an integration test instead.
