javascript - .toBe 函数中的 "Undefined is not a function"

Question

我正在编写一个测试来自动化一个场景，使用 PROTRACTOR:

我在 .toBe 得到“Undefined is not a function”，下面是我的代码:试图获取元素的偏移位置:

this.Then(/^I should have ONLY LOGO available on main page$/, function () { 
    element(by.id('mainPage')).getLocation().then(function (navDivLocation) { 
        var currTop = navDivLocation.y; 
        var currLeft = navDivLocation.x; 

        expect(currLeft).toBe(0); 
        expect(currTop).toBe(0); 
     }); 
});

Answer 1

cucumber 和 Jasmine 是mutually exclusive .

如果你还没有，你应该使用 Chai断言库:

expect(currLeft).to.equal(0); 
expect(currTop).to.equal(0);

要断言不同 Protractor 函数返回的 promise ，请使用 Chai-as-promised库 - 您将能够在 expect() 中传递 promise 。示例:

expect(elm.getText()).should.eventually.equal("my text");
