The BlazeMeter Chrome Extension : Record JMeter, Selenium, or Synchronized JMeter and Selenium

The BlazeMeter Chrome Extension:

The BlazeMeter chrome extension is a free tool that enables you to Record, Browse, Upload, and Run your testing scripts. The Chrome Extension supports recording JMX, JSON or YML files, for running in JMeter, Taurus or BlazeMeter as well as both JMeter and Selenium scripts, automatically and simultaneously.

Running Your JMeter and Selenium Script in BlazeMeter:

The new BlazeMeter Chrome extension records all of the HTTP/S requests that your browser sends, creates a JMeter or Selenium script, and uploads it to Blazemeter, where you can execute it with a single click.

In other words, you can run a JMeter and Selenium without even having them installed. There is no need to install JMeter or Selenium to record or run a performance test; the Chrome extension creates the script on its own.

Running Your JMeter and Selenium Script Locally:

On the other hand, if you have JMeter installed, you can convert your recording into a JMeter JMX file or Taurus YAML file, then edit or run it via your browser or on your local computer.  

Note: The extension needs to be able to communicate with blazemeter.com in order for the recording to be converted into a script.

1. Add Blazemeter Chrome Extension on your local computer

2. Record your actions, then play them back as a script

Screenshot in Selenium

How to capture Screenshot in Selenium Web-driver (C#)

OVERVIEW

Selenium Web-Driver provides the capability to capture screenshots during a test execution. This ability is really important when you need to investigate different failures that occurred during the execution or in some cases to track the different stages of the run.

The capability to take a screenshot with selenium is extracted from the "ITakesScreenshot" interface that allowing us to take a screenshot of the current page displayed in the driver instance.

Taking screenshot of the entire screen (All Elements)

In the following test, we will log into a web-page and take screenshot of the entire page in .JPEG format. We can create screenshot class in common driver and can use in entire project. 

#region screenshots

        // Create a class of screenshot in common driver

        public class SaveScreenShotClass

        {

            public static string SaveScreenshot(IWebDriver driver, string ScreenShotFileName) // Definition

            {

               // Determines where do you going to save the screenshot

                var folderLocation = YourfolderLocation.ScreenshotPath;

                if (!System.IO.Directory.Exists(folderLocation))

                {

                    System.IO.Directory.CreateDirectory(folderLocation);

                }

                // This method will take the screenshot

                var screenShot = ((ITakesScreenshot)driver).GetScreenshot();

                var fileName = new StringBuilder(folderLocation);

                fileName.Append(ScreenShotFileName); // Determine the picture name

                //fileName.Append(DateTime.Now.ToString("_dd-MM-yyyy_mss"));  // Determine the                              picture name with date formate

                fileName.Append(DateTime.Now.ToString("dd-mm-yyyy_mss"));

                fileName.Append(".jpeg");  // Determine the format of the picture

                screenShot.SaveAsFile(fileName.ToString(), ScreenshotImageFormat.Jpeg); //

                return fileName.ToString();

            }

        }

        #endregion

     // Now we can use screenshot method in all project with the help of below code

    SaveScreenShotClass.SaveScreenshot(driver, "PictureName");
