Is it possible to run code after all tests finish executing in MStest

Question

I am writing coded ui tests and I have the application open if it is not already open. Then if one of them fails I close the application the thing is I have multiple tests in mu

Answer 1

Perhaps what you're looking for is the TestCleanup attribute?

EDIT: Also, if you want to run something after all tests have been run, the AssemblyCleanupAttribute might be more appropriate.

Answer 2

IMPORTANT

Someone who is using base class can do assembly cleanup there as well

[TestClass]
public class Page : PageContract, IWindowControlAccess
{
[AssemblyCleanup()]
    public static void ApplicationCleanup()
    {
        Cleanup();
    }
}

Two important things here 1. [TestClass] attribute at the base is MANDATORY

2. signature of ApplicationCleanup see its a static method

That's it you are done. I had hard time struggling and debugging it.

Answer 3

If you just want to clean up after all tests inside a single class have finished, use the ClassCleanup attribute rather than the AssemblyCleanup attribute

Answer 4

Yes it is possible. You can use the AssemblyCleanup Attribute for this purpose:

Identifies a method that contains code to be used after all tests in the assembly have run and to free resources obtained by the assembly.

Here is an overview of all MSTest methods arranged according to execution time:

using Microsoft.VisualStudio.TestTools.UnitTesting;
using SampleClassLib;
using System;
using System.Windows.Forms;

namespace TestNamespace
{
    [TestClass()]
    public sealed class DivideClassTest
    {
        [AssemblyInitialize()]
        public static void AssemblyInit(TestContext context)
        {
            MessageBox.Show("AssemblyInit " + context.TestName);
        }

        [ClassInitialize()]
        public static void ClassInit(TestContext context)
        {
            MessageBox.Show("ClassInit " + context.TestName);
        }

        [TestInitialize()]
        public void Initialize()
        {
            MessageBox.Show("TestMethodInit");
        }

        [TestCleanup()]
        public void Cleanup()
        {
            MessageBox.Show("TestMethodCleanup");
        }

        [ClassCleanup()]
        public static void ClassCleanup()
        {
            MessageBox.Show("ClassCleanup");
        }

        [AssemblyCleanup()]
        public static void AssemblyCleanup()
        {
            MessageBox.Show("AssemblyCleanup");
        }

        [TestMethod()]
        [ExpectedException(typeof(System.DivideByZeroException))]
        public void DivideMethodTest()
        {
            DivideClass.DivideMethod(0);
        }
    }
}
