Introduction
In the realm of software development, testing is a crucial phase that ensures the quality and functionality of applications. MS Test Manager is an essential tool for managing and executing tests, particularly when integrated with powerful frameworks like Selenium WebDriver and MSTest. This guide provides an in-depth exploration of MS Test Manager, covering everything from setup to advanced usage, ensuring you can maximize its potential for visual testing.
What is MS Test Manager?
Understanding MS Test Manager
MS Test Manager is a testing tool provided by Microsoft that integrates with Visual Studio. It is designed to help developers and testers manage their testing efforts, execute automated tests, and analyze test results efficiently.
Key Features
Test Management: Organize and manage test cases, plans, and suites.
Automated Testing: Execute automated tests using MSTest, Selenium, and other frameworks.
Result Analysis: Analyze test results to identify issues and ensure quality.
Integration: Seamless integration with Visual Studio and other development tools.
Preparing Your Environment for MS Test Manager
Prerequisites
Before you start using MS Test Manager, ensure you have the following:
Visual Studio: The primary IDE for .NET development, which includes MS Test Manager.
.NET SDK: The software development kit for building and running C# projects.
Google Chrome and ChromeDriver: For running Selenium WebDriver tests.
Applitools Account: For visual testing and leveraging the Ultrafast Grid and Execution Cloud.
Installing ChromeDriver
Ensure ChromeDriver is installed and accessible via the system PATH. You can verify the installation by running chromedriver -v in your terminal.
Getting Started with MS Test Manager
Setting Up a Test Project
To create a new test project in Visual Studio:
Open Visual Studio: Launch the IDE and create a new project.
Select Project Template: Choose "Unit Test Project" for MSTest.
Configure Project: Name your project and configure settings as needed.
Integrating Selenium WebDriver and Applitools
To integrate Selenium WebDriver and Applitools into your project:
Install NuGet Packages: Add the necessary packages for Selenium WebDriver and Applitools Eyes SDK.
Configure Applitools: Set up your Applitools API key and configure visual testing options.
Example Project Setup
You can use the example project provided at Applitools GitHub. Clone the repository and follow the setup instructions.
Writing and Running Tests in MS Test Manager
Creating a Test Case
In Visual Studio, create a new test class and write your test methods. Use attributes like [TestClass] and [TestMethod] to define your test structure.
Sample Test Case
Here is a sample test case for the ACME Bank demo app:
csharp
using Applitools.Selenium;
using Applitools.VisualGrid;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Remote;
using System.Drawing;
namespace Applitools.Example.Tests
{
[TestClass]
public class AcmeBankTest
{
public const bool UseUltrafastGrid = true;
public const bool UseExecutionCloud = false;
public TestContext TestContext { get; set; }
private static string? ApplitoolsApiKey;
private static bool Headless;
private static BatchInfo Batch;
private static Configuration Config;
private static EyesRunner Runner;
private WebDriver Driver;
private Eyes Eyes;
[AssemblyInitialize]
public static void SetUpConfigAndRunner(TestContext context)
{
ApplitoolsApiKey = Environment.GetEnvironmentVariable("APPLITOOLS_API_KEY");
Headless = Environment.GetEnvironmentVariable("HEADLESS")?.ToLower() == "true";
if (UseUltrafastGrid)
{
Runner = new VisualGridRunner(new RunnerOptions().TestConcurrency(5));
}
else
{
Runner = new ClassicRunner();
}
Batch = new BatchInfo($"Example: Selenium C# MSTest with {(UseUltrafastGrid ? "Ultrafast Grid" : "Classic Runner")}");
Config = new Configuration().SetApiKey(ApplitoolsApiKey).SetBatch(Batch);
if (UseUltrafastGrid)
{
Config.AddBrowser(800, 600, BrowserType.CHROME);
Config.AddBrowser(1600, 1200, BrowserType.FIREFOX);
Config.AddBrowser(1024, 768, BrowserType.SAFARI);
Config.AddDeviceEmulation(DeviceName.Pixel_2, ScreenOrientation.Portrait);
Config.AddDeviceEmulation(DeviceName.Nexus_10, ScreenOrientation.Landscape);
}
}
[TestInitialize]
public void OpenBrowserAndEyes()
{
ChromeOptions options = new ChromeOptions();
if (Headless) options.AddArgument("headless");
if (UseExecutionCloud)
{
Driver = new RemoteWebDriver(new Uri(Eyes.GetExecutionCloudUrl()), options);
}
else
{
Driver = new ChromeDriver(options);
}
Driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(10);
Eyes = new Eyes(Runner).SetConfiguration(Config);
Eyes.SaveNewTests = true;
Eyes.Open(Driver, "ACME Bank Web App", TestContext.TestName, new Size(1200, 600));
}
[TestMethod]
public void LogIntoBankAccount()
{
Driver.Navigate().GoToUrl("https://demo.applitools.com");
Eyes.Check(Target.Window().Fully().WithName("Login page"));
Driver.FindElement(By.Id("username")).SendKeys("applibot");
Driver.FindElement(By.Id("password")).SendKeys("I<3VisualTests");
Driver.FindElement(By.Id("log-in")).Click();
Eyes.Check(Target.Window().Fully().WithName("Main page").Layout());
}
[TestCleanup]
public void CleanUpTest()
{
Eyes.Close();
Driver.Quit();
}
[AssemblyCleanup]
public static void PrintResults()
{
TestResultsSummary allTestResults = Runner.GetAllTestResults();
Console.WriteLine(allTestResults);
}
}
}Running Tests
To run tests, use the Test Explorer in Visual Studio or the dotnet CLI. Ensure your Applitools API key is set as an environment variable.
