我对自动化测试和ruby相当陌生。基本上，我试图在页面上找到元素并单击它们。对于android，当我运行代码来查找元素时，有时会花费很长时间。下面是运行查找元素过程的代码示例:
def find_element(element_name)
elements = nil
result = nil
if(is_iphone)
element_name.gsub("'", '\' * 4 + "'")
end
# Check if element_name is present in the lookup dictionary, if present, use value instead.
if(name_lookup(element_name, is_android == true ? "Android" : "iOS")) then
element_name = name_lookup(element_name, is_android == true ? "Android" : "iOS")
end
# Search by name or exact text.
value = '//*[@name="' + element_name + '"]'
elements = $driver.find_elements(:xpath, value)
if (elements.size() > 0)
result = elements[0]
return result
end
# Search by label.
label = '//*[@label="' + element_name + '"]'
elements = $driver.find_elements(:xpath, label)
if (elements.size() > 0)
result = elements[0]
return result
end
if(is_android)
# Search by resource id (Android only).
elements = $driver.find_elements(:id, element_name)
if (elements.size() > 0)
result = elements[0]
return result
end
end
# Search for element containing the text "element_name". Uses xpath.
# iOS searches by name, Android by text.
is_iphone ? (xpath = '//*[contains(@name, "' + element_name + '")]') : (xpath = '//*[contains(@text, "' + element_name + '")]')
elements = $driver.find_elements(:xpath, xpath)
if (elements.size() > 0)
result = elements[0]
return result
end
return result
end
本质上，正在发生的事情是，通过资源id进行搜索需要通过登录屏幕，并且不需要很长时间-实际上只需要几毫秒。然而，一旦我越过登录屏幕，搜索似乎要花很长时间。下面是一个日志示例:

有没有办法加快速度?如果需要的话，我会尽力回答问题来澄清这一点。谢谢!
只是想我更新一下这个，看起来速度慢是由动画引起的。在开发人员选项下关闭该选项可以显著加快测试速度。
您似乎正在使用$driver.find_elements，它有效地查找您的条件的所有元素，并给出所有发现结果的完整列表。
调用$driver.find_element应该更快，它返回第一个匹配。
