Protractor count elements and store the integer

Question

I want to count the elements in a list and then access the integer, not a Promise object. So starting with:

var questionList = questionContainer.all(by.className('someclass'));

如果该类有三个子元素,我想console.log(questionList.count())输出整数3,而不是Promise对象.这甚至可能吗？即使它是一些操作上的Promise.

Answer 1

protractor有这样的count()方法ElementArrayFinder:

expect(questionList.count()).toEqual(3);

注意,count()返回一个promise,expect()被"修补"以隐式解决promise.

例如,如果您需要在控制台上打印实际值,请使用以下方法明确解决承诺then():

questionList.count().then(function (count) {
    console.log(count);
});

或者,甚至更简单:

questionList.count().then(console.log);
