Got errors when running flutter test command

Question

I use flutter create testtest to create a sample app called testest to run the sample test case, but it throw errors, when I run flutter test ./test/widget_test.dart

errors:

flutter test

 void main() {
    testWidgets('Counter increments smoke test', (WidgetTester tester) async {
     // Build our app and trigger a frame.
     await tester.pumpWidget(new MyApp());

    // Verify that our counter starts at 0.
    expect(find.text('0'), findsOneWidget);
    expect(find.text('1'), findsNothing);

    // Tap the '+' icon and trigger a frame.
    await tester.tap(find.byIcon(Icons.add));
    await tester.pump();

    // Verify that our counter has incremented.
    expect(find.text('0'), findsNothing);
    expect(find.text('1'), findsOneWidget);
 });
 }

flutter doctor

Solution: I'm using fedora and to to solve this problem, run the command: sudo dnf install mesa-libGLU.x86_64

Does flutter doctor report any errors?

looks something related to libGLU...

Shell: /home/h/flutter/bin/cache/artifacts/engine/linux-  x64/flutter_tester: error while loading shared libraries: libGLU.so.1: cannot open shared object file: No such file or directory

check if you have the correct packet installed. If not:

## UBUNTU-LIKE ##
sudo apt-get install libglu1
## Fedora ##
dnf install mesa-libGLU.x86_64

or

## UBUNTU-LIKE ##
sudo apt-get install libglu1-mesa:i386
## Fedora ##
dnf install mesa-libGLU.i686

depending if you might need the 32bits version

it throws error when trying to install either libglu1 or libglu1-mesa:i386. Error:

sudo dnf install libglu1 Last metadata expiration check: 0:10:41 ago on Wed 10 Jan 2018 09:06:06 NZDT. No match for argument: libglu1

by the way, I'm using fedora

I edited to add the solution. It was so close, I guessed your system had installed the 64-bit already...

I'm not sure if this command dnf install mesa-libGLU.i686 would solve the issue, but 1 upvote for your effort :) thanks again
