Selenium C# NUnit how to take and save screenshot of failed test into the folder-CodePudding

I am new at Selenium and came up with an issue - how to take and save screenshot into the specific folder. I am using Selenium C# NUnit bond.

Have read many information on this but most of them is on - how to capture screenshot and add it to html file. But this is not what I need.

I need the screenshot file to be save into a folder so when I'm running Pipeline in AzureDevOps the "Tests results" block contain this screenshot as well and display it.

I was using this part of the code. The test runs and fails, but no screenshot was make

[OneTimeTearDown]
public void OneTimeTearDown()
        {
            if (TestContext.CurrentContext.Result.Outcome != ResultState.Failure)
            {
                var screenshot = ((ITakesScreenshot)driver).GetScreenshot();
                var filePath = "pathToTheFolder\\Screenshots\\"; 
                screenshot.SaveAsFile(filePath, Png);
            }
        }

Maybe someone can help on this and maybe share the knowledge and the code as well)

Thank you all!

Try

using System.Drawing; //add this using statement

[OneTimeTearDown]
public void OneTimeTearDown()
{
    if (TestContext.CurrentContext.Result.Outcome != ResultState.Failure)
    {
        var screenshot = ((ITakesScreenshot)driver).GetScreenshot();
        var filePath = "pathToTheFolder\\Screenshots\\"; 
        screenshot.SaveAsFile(filePath   System.Drawing.Imaging.ImageFormat.Png);
    }
}

This tutorial looks like what you need

Found a way how to reach out my goal - to save screenshots for failed tests in a bin folder of the project and attach them to the Pipeline "Test Result" section in further. This is the final workable code. I have removed it from [OneTimeTearDown] and set it to [TearDown]. And also have added attachment with the last row, that allows to sent screenshots to Pipelines "Test result" block.

This is my Base.cs file where I am locating IWebDriver, all Setup and TearDown methods

using E2E_Tests.TestData;
using OpenQA.Selenium.Firefox;
using OpenQA.Selenium;
using WebDriverManager.DriverConfigs.Impl;
using OpenQA.Selenium.Chrome;
using System.Configuration;
using NUnit.Framework.Interfaces;

        [TearDown]
        
                public void TearDown()
                {
                    TakeScreenshotDefaultImageFormat();
                    driver.Close();
                }
                public void TakeScreenshotDefaultImageFormat()
                {
                    
                    if (TestContext.CurrentContext.Result.Outcome == ResultState.Error)
                    {
                        var screenshot = ((ITakesScreenshot)driver).GetScreenshot();
                        var screenshotDirectoryPath = Path.Combine(TestContext.CurrentContext.TestDirectory, "Screenshots\\");
                        if (!Directory.Exists(screenshotDirectoryPath))
                        {
                            Directory.CreateDirectory(screenshotDirectoryPath);
                        }
                        var currentDate = DateTime.Now;
                        var filePath = $"{screenshotDirectoryPath}{TestContext.CurrentContext.Test.Name}_{currentDate.ToString("yyyy.MM.dd-HH.mm.ss")}.png";
                        screenshot.SaveAsFile(filePath);
                        TestContext.AddTestAttachment(filePath);
                    }
                }
