                                .SingleOrDefault(e => e.SectionId ==  editSecId);

            Assert.AreEqual<int>(expectedSec.SectionId, editSec.SectionId,$"Section Id does not match");

            var editSecName = DbContextMocker.SeedData_Sections[0].SectionName;
            var changedSecName = editSecName.ToUpper();

            // Act

            var actionResult = await controller.Edit(editSecId);

            var editSec = (actionResult as ViewResult).Model as Section;
            editSec.SectionName = changedSecName;
            actionResult = await controller.Edit(editSecId, editSec);

            // Assert
            Assert.IsInstanceOfType(actionResult, typeof(RedirectToActionResult));
            Assert.AreEqual("Index", (actionResult as RedirectToActionResult).ActionName);

        }

This is the code for the Editing Section in Project. But I want to make Test for creating Section in my project.In this Edit one Seed Data is the mock data that i am using .But in create one I have to create a new object of section to test is it creating or not ? So I have written some code .But it's not working so I need your help and suggestions. I am attaching my code below.Thank You
