失败：无法读取未定义

Question

片段的特性 '结果' 采取截图的测试失败

afterEach(function() { 

     var spec = jasmine.getEnv().currentSpec; 
     var passed = spec.results().passed(); 

     if (!passed) { 
     browser.takeScreenshot().then(function(png) { 
      writeScreenShot(png, "screenshot.png"); 
     }); 
     } 

     function writeScreenShot(data, filename) { 
       var stream = fs.createWriteStream(filename); 
       stream.write(new Buffer(data, 'base64')); 
       stream.end(); 
     } 

    }); 

控制台错误

Message: 
    Failed: Cannot read property 'results' of undefined 
    Stack: 
    TypeError: Cannot read property 'results' of undefined 
     at Object.<anonymous>

返回undefined这里，

var spec = jasmine.getEnv().currentSpec; 
console.log(spec); 

看起来像是由于Jasmine 2;任何备用解决方案也欢迎！我用Jasmine 2

Answer 1

从Jasmine 2.0开始，不再支持env.currentSpec。

Answer 2

“var spec”没有被设置为任何东西。这意味着“jasmine.getEnv（）。currentSpec”不能以任何理由工作。
