如何设置飞镖单元测试中的测试超时时间？

Question

是否可以设置测试运行的最长时间？就像：

@Test(timeout=1000) 
public void testSomething() {} 

in jUnit？

Answer 1

尝试添加下面一行在你的main()测试

void main(List<String> args) { 
    useHtmlEnhancedConfiguration(); // (or some other configuration setting) 
    unittestConfiguration.timeout = new Duration(seconds: 3); // <<== add this line 

    test(() { 
    // do some tests 
    }); 
} 

你可以很容易地安装使用setUp()和tearDown()和Timer

library x; 

import 'dart:async'; 
import 'package:unittest/unittest.dart'; 

void main(List<String> args) { 
    group("some group",() { 
    Timer timeout; 
    setUp(() { 
     // fail the test after Duration 
     timeout = new Timer(new Duration(seconds: 1),() => fail("timed out")); 
    }); 

    tearDown(() { 
     // if the test already ended, cancel the timeout 
     timeout.cancel(); 
    }); 

    test("some very slow test",() { 
     var callback = expectAsync0((){}); 
     new Timer(new Duration(milliseconds: 1500),() { 
     expect(true, equals(true)); 
     callback(); 
     }); 
    }); 

    test("another very slow test",() { 
     var callback = expectAsync0((){}); 
     new Timer(new Duration(milliseconds: 1500),() { 
     expect(true, equals(true)); 
     callback(); 
     }); 
    }); 


    test("a fast test",() { 
     var callback = expectAsync0((){}); 
     new Timer(new Duration(milliseconds: 500),() { 
     expect(true, equals(true)); 
     callback(); 
     }); 
    }); 

    }); 
} 

这个时间保护失灵，整个组，但组可以嵌套，因此您可以完全控制应该监视哪些测试超时。
