我正面临着量角器测试的一些奇怪问题。我使用以下代码来获取元素的文本。
getTitleElementValue(): Promise<string> {
return this.getTitleElement().getAttribute('value')
}
直到我将代码推送到git之前一切顺利。我立刻拉了最新的代码,然后我收到了错误
Type 'promise.Promise<string>' is not assignable to type 'Promise<string>'
我对输出感到困惑,需要一些关于这个问题的输入。我想提供任何其他细节。下面是package.json

答案 0 :(得分:5)
因为Protractor具有自Promise
个实现,目前Protractor仍然使用自Promise
工具,不使用Nodejs native Promise
。
您使用Nodejs native Promise
声明了结果值,应该使用Protractor self Promise
工具。
import { browser, by, protractor, promise, ElementFinder } from 'protractor'
getTitleElementValue(): promise.Promise<string> {
return this.getTitleElement().getAttribute('value')
}
仅供参考,量角器开始使用Nodejs本机Promise正在进行并计划于2018/10发生。
