In order to create a android/web app I want to run flutter tests on specific platforms. When I specify "chrome" I obtain "No tests ran." Of course app is working when I do "flutter run -d chrome"

The problem is easy to reproduce with flutter starting app. Here's what I've done on linux : 

mkdir chrome_test
cd chrome_test
create .
flutter test test/

=> All tests passed!

When I add @TestOn("vm") at beginning of test/widget_test.dart => all tests passed!

When I add @TestOn("chrome") at beginning of test/widget_test.dart => No tests ran.

Method (1)

  1. open a terminal

  2. go to root the directory of the project

  3. Type this => flutter run -d chrome --web-port 2021 test/home_test.dart or something like that

  4. wait for chrome to jump out

  5. see the results on the terminal!!

Note => change test/home_test.dart with your file name !.

I hope that will work for you!
