Can We write Unit test methods in .aspx.cs page?

Question

Can we write test methods in .aspx.cs page? If yes then how? I need to write test method for the code which is in Page_Load method. Please suggest if there is any solution.

Answer 1

Probably you can, but it will be much cleaner if you extract the logic of the Page_Load method into a model class and then test it separately.

Why?

• Reuse logic of the method in other pages
• Better separation of model and presentation
• Cleaner code that is easier to test

Sample:

// Home.aspx.cs
Page_Load()
{
    //Lots of code here
}


// or else Home.aspx.cs
Page_Load()
{
    Foo f = new Foo();
    var result = f.DoThings();
}

//Unit test
Page_Load_FooDoesThings()
{
    //Arrange
    Foo f = new Foo();
    var expected = ...;
    
    //Act
    var actual = f.DoThings();
    
    //Assert
    Assert.AreEqual(expected, actual)
}
