量角器清除()不工作

我有两个测试:

  it('should filter the phone list as user types into the search box', function() {

    var results = ptor.findElements(protractor.By.repeater('phone in phones').column('phone.name'));
    results.then(function(arr) {
            expect(arr.length).toEqual(3);
    });

    var queryInput = ptor.findElement(protractor.By.input('query'));

    queryInput.sendKeys('nexus');

    results = ptor.findElements(protractor.By.repeater('phone in phones').column('phone.name'));
    results.then(function(arr) {
        expect(arr.length).toEqual(1);
    });

    queryInput.clear();
    queryInput.sendKeys('motorola');

    results = ptor.findElements(protractor.By.repeater('phone in phones').column('phone.name'));
    results.then(function(arr) {
        expect(arr.length).toEqual(2);
    });

});

it('should display the current filter value within an element with id "status"',
    function() {
        //expect(element('#status').text()).toMatch(/Current filter: s*$/);
        var queryInput = ptor.findElement(protractor.By.input('query'));
        queryInput.clear();

        expect(ptor.findElement(protractor.By.id('status')).getText()).toMatch('Current Filter:');

        //input('query').enter('nexus');

        //queryInput.clear();
        //queryInput.sendKeys('nexus');

        //expect(element('#status').text()).toMatch(/Current filter: nexuss*$/);
        //expect(ptor.findElement(protractor.By.id('status')).getText()).toMatch('^Current Filter:.');

        //alternative version of the last assertion that tests just the value of the binding
        //using('#status').expect(binding('query')).toBe('nexus');
    });

第一个测试，搜索框，效果很好.第二个测试 status 没有通过，因为在 queryInput 中输入的最后一个值被传递到第二个测试，并且 queryInput.clear() 不起作用.但是，在第二个测试中，如果我调用 queryInput.sendKeys("something")，则会显示something".如果我在第二个测试中取出 clear()，我会看到motorolaso​​mething".因此，虽然 clear() 似乎在工作，但如果我在第二个测试中只有 clear()，我的测试没有通过，当我运行第二个测试时，即使调用 clear()，我也会看到motorola"在第二次测试之前.

queryInput.clear().then(function() {
    queryInput.sendKeys('motorola');
})
