Need to test for <requestedExecutionLevel level="highestAvailable" uiAccess="false" /> in app.manifest.
I need to be sure, that app will have admin rights.
Need NUnit scenario written in C# .NET.

Needing to do exactly what you did I finally developed the following given your “just read the xml” approach. Note that in order for this to work properly I also had to change my testsettings file to manually deploy the app.manifest file so that it would be there to read.

    public TestContext TestContext { get; set; }

    [TestMethod]
    public void Proper_Permissions_Set_In_app_manifest()
    {
        // Arrange
        var expected = "requireAdministrator";
        using (StreamReader reader = new StreamReader(Path.Combine(TestContext.TestDeploymentDir, "app.manifest")))
        {
            var doc = XDocument.Load(reader.BaseStream);
            var node = doc.Descendants("{urn:schemas-microsoft-com:asm.v3}requestedExecutionLevel").First();
            var attribute = node.Attribute("level");

            // Act
            var actual = attribute.Value;

            // Assert
            Assert.AreEqual(expected, actual);
        }
    }

I hope this helps someone else…
