運行摩卡測試循環同步

Question

我陣列上運行的摩卡測試循環，像這樣：

it('each should have permissions defined for each role', function(done) { 
    async.forEach(_permissions, function(permission, callback) { 
     log.debug(permission.permissions.should.be.an.instanceOf(Array).and.not.be.empty); 
     callback(permission.permissions.should.be.an.instanceOf(Array).and.not.be.empty); 
    }, 
    function(result) { 
     log.debug(result); 
     done(); 
    }); 
}); 

當我登錄出來，看來即使我使用done()回調異步運行。是這樣嗎？我的測試是否仍然成功執行，還是僅執行第一個測試，然後返回成功結果？

這裏是控制檯輸出：

[Tue Dec 02 2014 09:24:07 GMT-0800 (PST)] DEBUG { obj: [ 'permissions!' ], params: { operator: 'to be empty' }, negate: false } 
    ✓ each should have permissions defined for each role // <- here's the test result 
[Tue Dec 02 2014 09:24:07 GMT-0800 (PST)] DEBUG { obj: [ 'permissions!' ], params: { operator: 'to be empty' }, negate: false } 
[Tue Dec 02 2014 09:24:07 GMT-0800 (PST)] DEBUG { obj: [ 'permissions!' ], params: { operator: 'to be empty' }, negate: false } 
[Tue Dec 02 2014 09:24:07 GMT-0800 (PST)] DEBUG { obj: [ 'permissions!' ], params: { operator: 'to be empty' }, negate: false }

使用eachSeries，這讓我也過去。 forEach是平行版本。

使用像這樣：

it('each should have permissions defined for each role', function(done) { 
    async.eachSeries(_permissions, function(permission, callback) { 
     permission.permissions.should.be.an.instanceOf(Array).and.not.be.empty; 
     callback(); 
    }, 
    function(err) { 
     done(); 
    }); 
});
