Do you see any suspicious logs in Console when you reproduce that could give a hint as to what's interrupting the call? Maybe from syspolicyd or kernel?

3 years ago @jmagman Running a test battery (running tests from a parent directory) the resulting log contains some additional info on shell stack. Really don't expect them to be useful. I've never seen anything more than that.

3 years ago Same issue here... Upgraded to MacOS Big Sur and then started to have two issue types :
1) with antivirus: had to stop the shields like here (see this Switch off these Core Shields if using Avast Security)
2) then some of the unit tests are failing with :

3 years ago @jmagman good tip, thanks.. after looking better I could spot my avast premium security antivirus having something to do with this
i did try several ways to configure it (e.g. including stoping all shields and any scanning!?) but in the end, i had to uninstall avast and now the tests are working - not too happy about it but at least I can continue for now

3 years ago @jmagman I already had to downgrade back to Catalina to be able to work, so cannot check errors anymore

3 years ago I can confirm that, also in my case, removing Avira solved the issue.

3 years ago I just upgraded my Macbook Air back to Big Sur and problem still persists, flutter unit tests fail the same way.
I had a Macbook Pro installed also with Big Sur MacOS and it did not face the same issue with flutter tests.
only difference between these machines is that Macbook pro does not have company mandated MS ATP software installed.
Now.... I cannot uninstall the MS ATP software as that is against company policy, so would be really good that some help could be found from here as well....
haamaanaa
commented
3 years ago We also verified that removing Microsoft ATP "solves" the issue of running flutter tests....
but that cannot be the solution in real world, can it?

3 years ago Duplicated from #70940
I faced the same issue, when I migrated to Big Sur. Now I have Big Sur 11.2, but the issue with tests running is still reproducible.
I managed to find temporary workaround for it: to run command with concurrency parameter set to 1 (by default it is 10):
flutter test --concurrency 1In 95% of runs, error does not appear, but in rest 5% - it does. I suppose, error is somehow related to filesystem access or some access race condition. And I do not rely on my temporary solution, because it decrease running time (because only 1 job is used).
I believe the issue will be investigated and fixed asap.

3 years ago @ihorvitruk do you also have MS ATP security app installed? or some other security scanner app?
haamaanaa
commented
3 years ago to test with MacOS BigSur + [insert AV scanner here]
import 'package:test/test.dart';
void main() {
test('Test BigSur vs Flutter', () {
expect(1, 1);
});
}fails after some random amount of tries, at least with MS ATP scanner enabled

3 years ago I faced the same issue, running: MacOs Big Sur with Avast Antivirus.
In the test case I was just reading file.
Noticed that if I disable "File shield" feature from Avast it will not reproduce.
Workaround is to use that flutter test --concurrency 1
haamaanaa
commented
3 years ago Upgraded to BigSur 11.2.3 today and it solved issue for about 98,6%, even with having antivirus program installed & running. we are also using flutter 2 now.
11.2.3 release notes say: Processing maliciously crafted web content may lead to arbitrary code execution
Running tests in test suite (like with command-line command flutter test) still fails a one random class about 10% of tries. same test succeeds in isolation about 98,6 success rate. earlier when running test suite, more than half test classes would fail, now only singular class fails, sometimes
So something was made better, but still not 100% "there"

3 years ago I updated my Mac to BigSure 11.2.3 and actually faced the same issue: always and multiple times, running the unit tests, getting the same error Getting current working directory failed, path = '' (OS Error: Interrupted system call, errno = 4):
I have same as @haamaanaa Microsoft Defender ATP.
After update to latest version of Microsoft Defender ATP then failure happen anyway and randomly time to time in the same way as above loading the test.

3 years ago Good news from my side: I found a new workaround. It can be used until the issue is fixed (no matter by whom).
Workaround is to use Retry annotation (https://api.flutter.dev/flutter/test_api/Retry-class.html)
Annotation should be added to the top of the file with tests. Documentation from the above link says: A test with retries enabled will be re-run if it fails for a reason other than TestFailure. It means, current issue situation is the exact case, when this annotation should be used. If error Interrupted system call, errno = 4 occurs, test is just run again until it succeed or TestFailure happened or maximum retries count is reached.
I added @Retry(10) to test files in my project, but in practice, 4 - is the maximum retries count that I saw. All of the retries are done at the same second of time, it means, that even if you have hundreds or even thousands of tests, tests running time will not be increased a lot.

3 years ago If your Anti virus software supports exclusions for real-time scan, you can try excluding your workspace/project folder and maybe the temp folder or /private/var/folders on BigSur.
Seems to work for now.

commented
3 years ago The latest Big Sur update has been pushed out. Upgrading macOS should solve the issue with Microsoft Defender ATP and Interrupted system call.

commented
3 years ago I can confirm that this no longer fails after the MacOS 11.3 update. @viatsko Do you have any background information on why this is?
haamaanaa
commented
3 years ago It might also be that Microsoft have pushed an update to MS ATP itself with automated updates
Have to check if was fixed for us as well....
EDIT: indeed, error seems to have gone the way of Moas
Reported by @haamaanaa at https://github.com/flutter/flutter/issues/70940
Steps to Reproduce
did try to clean flutter pub cache with flutter pub cache repair, and also by deleting said cache folder from laptop and then running flutter pub get again on project and running tests.... still failed
Expected results:
unit test to run successfully at all times (In Catalina OS version, same test(s) run without fail)
Actual results:
at random runs the test fails
