量角器返回一个对象但是期望 - element.getText（）的值 [英] Protractor return an object but expected - value of element.getText()

问题描述

无法理解为什么它返回一个对象而不是文本值，一些测试代码：

Unable to understand why it return an object not a value of text, some test code:

describe('columns swap', function () {

    describe('location column ', function () {
        it('should swap right', function () {
            browser.sleep(10000);
            var fColumn = element(by.xpath('(//*[@class="k-link"])[2]')).getText();
            console.log(fColumn); 

控制台输出：

>   columns swap
>     location column { ptor_:    { controlFlow: [Function],
>      schedule: [Function],
>      getSession: [Function],
>      getCapabilities: [Function],
>      quit: [Function],
>      actions: [Function],
>      executeScript: [Function],
>      executeAsyncScript: [Function],
>      call: [Function],
>      wait: [Function],
>      sleep: [Function],
>      getWindowHandle: [Function],
>      getAllWindowHandles: [Function],
>      getPageSource: [Function],
>      close: [Function],
>      getCurrentUrl: [Function], ...

此外，如果我将此部分与expect（）一起使用：

Also if I use this part with expect():

    expect(columnSorting.acpColumn.getText()).to.eventually.equal(fColumn);

我看到：

  1) columns swap location column  should swap right:
     AssertionError: expected 'Location' to equal { Object (ptor_, parentElement
ArrayFinder, ...) }

因此，出于某种原因，我可以从期望中获取文字并且正确 - 位置

So for some reason I can get text from expect and it correct - 'Location'

我做错了什么？

推荐答案

getText（） 返回承诺。如果要记录实际值，则需要解决它：

getText() returns a promise. If you want to log an actual value, you need to resolve it:

element(by.xpath('(//*[@class="k-link"])[2]')).getText().then(function (value) {
    console.log(value);

    expect(columnSorting.acpColumn.getText()).to.eventually.equal(value);
});

请注意 expect（ ）在protractor / jasminewd中修补以隐式解决承诺。换句话说，您可以断言 getText（）等于所需的文本：

---

Note that expect() is "patched" in protractor/jasminewd to resolve promises implicitly. In other words, you can assert getText() being equal to the desired text:

expect(element(by.xpath('(//*[@class="k-link"])[2]')).getText()).toEqual('My Text');
