How to use PuppeteerSharp inside an UWP App?

PuppeteerSharp does not support in UWP, You could check PuppeteerSharp source code to verify this. This is DownloadsFolder = Path.Combine(Directory.GetCurrentDirectory(), ".local-chromium") and matched path is "{AppRoot}\bin\x86\Debug\AppX.local-chromium". In the following code we call Create method in it, but above path is read-only in UWP.

    public async Task<RevisionInfo> DownloadAsync(int revision)
    {
        var url = GetDownloadURL(Platform, DownloadHost, revision);
        var zipPath = Path.Combine(DownloadsFolder, $"download-{Platform.ToString()}-{revision}.zip");
        var folderPath = GetFolderPath(revision);

        if (new DirectoryInfo(folderPath).Exists)
        {
            return RevisionInfo(revision);
        }

        var downloadFolder = new DirectoryInfo(DownloadsFolder);
        if (!downloadFolder.Exists)
        {
            downloadFolder.Create();
        }

        if (DownloadProgressChanged != null)
        {
            _webClient.DownloadProgressChanged += DownloadProgressChanged;
        }
        await _webClient.DownloadFileTaskAsync(new Uri(url), zipPath).ConfigureAwait(false);

        if (Platform == Platform.MacOS)
        {
            //ZipFile and many others unzip libraries have issues extracting .app files
            //Until we have a clear solution we'll call the native unzip tool
            //https://github.com/dotnet/corefx/issues/15516
            NativeExtractToDirectory(zipPath, folderPath);
        }
        else
        {
            ZipFile.ExtractToDirectory(zipPath, folderPath);
        }

        new FileInfo(zipPath).Delete();

        var revisionInfo = RevisionInfo(revision);

        if (revisionInfo != null && GetCurrentPlatform() == Platform.Linux)
        {
            LinuxSysCall.Chmod(revisionInfo.ExecutablePath, LinuxSysCall.ExecutableFilePermissions);
        }
        return revisionInfo;
    }

How To Run Cypress Tests In Azure DevOps Pipeline

When software developers took years to create and introduce new products to the market is long gone. Users (or consumers) today are more eager to use their favorite applications with the latest bells and whistles. However, users today don’t have the patience to work around bugs, errors, and design flaws. People have less self-control, and if your product or application doesn’t make life easier for users, they’ll leave for a better solution.

LIVE With Automation Testing For OTT Streaming Devices ????

People love to watch, read and interact with quality content — especially video content. Whether it is sports, news, TV shows, or videos captured on smartphones, people crave digital content.

Thus, the OTT platform’s concept of viewing anything, anytime, anywhere has hit the right chord.

Acquiring Employee Support for Change Management Implementation

Enterprise resource planning (ERP) is a form of business process management software—typically a suite of integrated applications—that assists a company in managing its operations, interpreting data, and automating various back-office processes. The introduction of a new ERP system is analogous to the introduction of a new product into the market. If the product is not handled appropriately, it will fail, resulting in significant losses for the business. Most significantly, the employees’ time, effort, and morale would suffer as a result of the procedure.
