不能分配给'Expected< Promise< string>>'类型的参数在编辑器中 [英] is not assignable to parameter of type 'Expected<Promise<string>>' in editor

问题描述

我的测试是从命令行传递的，但我使用 Atom 编辑 typescript 源。

My tests are passing from command line, however I edit the typescript source using Atom.

当我在编辑器中打开其中一个测试文件时，我发现此行有错误：

And when I open one of the test files in my editor, I'm seeing an error on this line:

expect(pageObject.name.getText()).toEqual('Some name');

这是错误：

Typescript

Error
Argument of type '"Some name"' is not assignable to parameter of type 'Expected<Promise<string>>'.at line 16 col 50

为什么这会在我的编辑器中显示？然而测试通过。

Why does this show in my editor? Yet tests pass.

运行量角器测试的命令：

Command to run protractor tests:

protractor dist/protractor.config.js

推荐答案

getText（）返回promise。请参阅 doc 。

getText() returns promise. See the doc.

如果你想从一个元素断言文本，你需要chai-as-promise。
请参阅示例。

If you want to assert text from an element you need chai-as-promise. See example.
