Answer 1

As i faced same issue i changed my code bit. From

strhtmlTemplate = File.ReadAllText(System.Web.Hosting.HostingEnvironment.MapPath(Lgetfilepath.CVal));

To

strhtmlTemplate = File.ReadAllText(HttpContextFactory.Current.Server.MapPath(Lgetfilepath.CVal));

For Unit test

public HttpContextBase mockHttpContextBase()
        {
            var moqContext = new Mock();
            var moqRequest = new Mock();
            var moqServer = new Mock();
            var moqPath = new Mock();
            moqContext.Setup(x => x.Request).Returns(moqRequest.Object);
            moqContext.Setup(x => x.Server.MapPath(@"~\Data\xxxxxxx")).Returns(Environment.CurrentDirectory+@"\xxxxxx");                
            setupApplication(moqContext);

            return moqContext.Object;
        }

Now we while Writing TestClass you need to refer above method to mock. Hope it will helpful for your TestCases.

MockDataUT mockData = new MockDataUT();
var mockRequestContext = new HttpRequestContext();
HttpContextFactory.SetCurrentContext(mockData.mockHttpContextBase());
