robotframework混合庫關鍵字不會返回值

Question

我已經在python for robotframework中構建了一個混合庫。此API的其中一種方法返回一個字符串，我想將其分配給測試中的robotframework變量。

${sms_1_2}= encrypt_sms_return_ciphered  1@ercom.fr  2@ercom.fr  sms1to2 

我已驗證的encrypt_sms_return_ciphered的Python代碼沒有返回一個字符串。但問題是robotframework變量被分配給None。

下面是方法的代碼：

@InstanceIndex.check_short_name 
def encrypt_sms__return_ciphered(self, sender, receiver, clearsms): 
    self.encrypt_sms(sender, receiver, clearsms) 
    ClientIndex.success_if(sender, "isSmsSent", receiver, clearsms) 
    cipheredsms = self.smsSent[receiver, clearsms] 
    del self.smsSent[receiver, clearsms] 
    return cipheredsms 

這裏是check_short_name裝飾的代碼：

@staticmethod 
def check_short_name(method): 
    def wrapper(self, short_name, *args, **kwargs): 
     if short_name != self.short_name: 
      try: 
       getattr(self.collection.iterate(), method.__name__)(short_name, *args, **kwargs) 
      except StopIteration: 
       raise Exception("item \"%s\" is not a member of %s, or method \"%s\" is not defined for any member of %s" % (short_name, self.collection.name, method.__name__, self.collection.name)) 
     else: 
      self.collection.rewind() 
      return method(self, short_name, *args, **kwargs) 
    return wrapper

我發現了問題所在：迴歸價值鏈從開始被打破。在getattr之前沒有返回：

@staticmethod 
def check_short_name(method): 
    def wrapper(self, short_name, *args, **kwargs): 
     if short_name != self.short_name: 
      try: 
       **return** getattr(self.collection.iterate(), method.__name__)(short_name, *args, **kwargs) 
      except StopIteration: 
       raise Exception("item \"%s\" is not a member of %s, or method \"%s\" is not defined for any member of %s" % (short_name, self.collection.name, method.__name__, self.collection.name)) 
     else: 
      self.collection.rewind() 
      return method(self, short_name, *args, **kwargs) 
    return wrapper
