flutter test fails. compiler error getter not found 'main'

Question

I'm trying to run flutter test using the terminal and i receive the following error. the following file C:/Users/User/AppData/Local/Temp/flutter_test_listener.e6fa92b4-6cd1-11e9-b9cb-68f728ca4610/listener.dart doesn't exist in the directory specified.

here's the error:

Compiler message: file:///C:/Users/User-45/AppData/Local/Temp/flutter_test_listener.e6fa92b4-6cd1-11e9-b9cb-68f728ca4610/listener.dart:46:17:

Error:Getter not found: 'main'. return test.main;

my project's directory is in another folder. how can i solve this? Thank you

Solution 1

In my case, it happened that one of my helper classes in the test folder, had a name that ended "_test", and the compiler was looking for a main method. So I renamed the helper class, and problem solved.

Solution 2

If anybody faces the above problem then try to add main() in test class and if you have added then remove it out of test class curly braces. I faced this and removed the main() out of test class.

Eg...

class GetConcreteNumberTrivia_Test extends Mock
    implements NumberTriviaRepository {}

void main() {

.....my implementation......
}

Solution 3

It seems this error can have a lot of different causes. In my case the problem was a file foo_test.dart with the only content //TODO. So it was basically empty and the compiler could not find the excpected main method. The weird thing was, that it threw the Error in another test!

When I removed foo_test.dart, it worked again! Hope this helps!

Solution 4

I had this error when a merge mess put the main() within a class.

Solution 5

I also got this error. My problem has been how I named the files for my tests. The test runner is looking for this pattern "*_test.dart" (hier). After renaming my test files accordingly, the test runner executes the test without any errors.
