Question

这里是我想在单击按钮（createRoom_btn）之前检查输入nick_name和room_name的值的代码。但是我没有得到如何使用量角器检查单个if语句中的多个条件。

var nick_name = element(by.model('user.vcard.nickname'));
var room_name = element(by.model('roomName'));
var createRoom_btn = element(by.tagName('button'));
describe('Protractor Demo App', function () {
    it('should click on create room button', function () {
        condition = function () {
            return [
                nick_name.getAttribute('value').then(function (value) {
                    return value.length > 0
                }),
                room_name.getAttribute('value').then(function (value) {
                    return value.length > 0
                })
            ];
        };
        browser.wait(condition, 8000, "Text is still not present").then(function (resp) {
        });
        //button click         
        browser.actions().mouseMove(createRoom_btn).click();
    });
});

您应该使用public sealed partial class WebViewLocalImage : Page { public WebViewLocalImage() { this.InitializeComponent(); Loaded += MainPage_Loaded; } private void MainPage_Loaded(object sender, RoutedEventArgs e) { var uri = this.myWebView.BuildLocalStreamUri("InternalAssets", "example.html"); this.myWebView.NavigateToLocalStreamUri(uri, new StreamUriResolver()); } } public sealed class StreamUriResolver : IUriToStreamResolver { public IAsyncOperation<IInputStream> UriToStreamAsync(Uri uri) { string path = uri.AbsolutePath; return GetContent(path).AsAsyncOperation(); } private async Task<IInputStream> GetContent(string URIPath) { try { Uri localUri = new Uri("ms-appx:///Assets/" + URIPath); StorageFile f = await StorageFile.GetFileFromApplicationUriAsync(localUri); IRandomAccessStream stream = await f.OpenAsync(FileAccessMode.Read); return stream.GetInputStreamAt(0); } catch (Exception) { System.Diagnostics.Debug.WriteLine("Invalid URI"); } return null; } } - http://www.protractortest.org/#/api?view=ProtractorExpectedConditions.prototype.and - 来组合条件。如果您有值等待的值，请使用'and' ExpectedCondition - http://www.protractortest.org/#/api?view=ProtractorExpectedConditions.prototype.textToBePresentInElementValue。

否则，要检查是否输入了值，您可以编写自定义条件来检查长度。

textToBePresentInElementValue ExpectedCondition

为房间名称创建类似的内容 - var valuePresentNick = function() { return nick_name.getAttribute('value').then(function(txt) { return txt.length > 0; }); };

valuePresentRoom

如何使用量角器检查多个条件是真还是假，这样有助于在点击之前验证输入
