如何在量角器预期运行之前返回承诺？

Question

Person.prototype.checkAssignmentIncomplete = Person.chain(function (data) { 
var self = this; 

var assignmentPane = self.browser.element(by.id(data.testId + '#' + data.deadline)); 
expect(assignmentPane.isPresent()).toBe(true); 

assignmentPane.click(); 
self.browser.waitForAngular(); 

var foundName = false; 
var promises = []; 
element.all(by.binding('member.user.fullname')).each(function (nameColumn) { 
    var row = nameColumn.element(by.xpath('..')); 
    var promise = nameColumn.getText().then(function (name) { 
     foundName = foundName || data.name === name; 
     if (foundName) { 
      var reviewButton = row.element(by.className('icon')); 
      expect(reviewButton.isPresent()).toBe(false); 
     } 
    }); 
    promises.push(promise); 
}); 

q.all(promises).then(function() { 
    expect(foundName).toBe(true); 
}); 

}); 

我在量角器中的自动化测试有问题，它似乎认为foundName是错误的，我知道一个事实，当它运行它确实是真的。我的结论是，在诺言完成之前，期望函数正在运行。

我想知道如何确保承诺已完成，然后在expect函数中检查foundName？

var self = this; 

var assignmentPane = self.browser.element(by.id(data.testId + '#' + data.deadline)); 
expect(assignmentPane.isPresent()).toBe(true); 

assignmentPane.click(); 
self.browser.waitForAngular(); 

var foundName = false; 
element.all(by.binding('member.user.fullname')).each(function (nameColumn) { 
    var row = nameColumn.element(by.xpath('..')); 
    nameColumn.getText().then(function (name) { 
     foundName = foundName || data.name === name; 
     if (foundName) { 
      var reviewButton = row.element(by.className('icon')); 
      expect(reviewButton.isPresent()).toBe(false); 
     } 
    }); 
}).then(function() { 
    expect(foundName).toBe(true); 
}); 

这不是一个真正理想的解决方案，但在每个函数似乎解决了我所遇到的问题后添加承诺。

尝试使用protractor.promise.all（承诺）函数有所回调时承诺的阵列解决 - https://angular.github.io/protractor/#/api?view=promise.all

q LIB是可能不会在这里工作
