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 multiple projects is there a way to close the application after all of the tests are done executing? Is there maybe something in the testSettings file?

If this helps at all, all of my test classes derive from one codeduiTestBase which is how I set up the settings I do have.

I do not want to have to open and close the application before and after each test runs because it is a big application and it takes too long to load.

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);
        }
    }
}
