HTML 5 Web Storage : Local and Session

In HTML 5 the web application can store the data locally within the browser which can’t be transferred to the server. Before HTML 5, the local data in client side was stored in the cookies.

There are two types of web storage.
  1. Local Storage
  2. Session Storage
Local Storage : 
When we store data in Local storage, It can not be cleared until user manually clears the browser cache or pro-grammatically clears the storage.

Add Data:
Syntax : localStorage.setItem('key','value')
Example : localStorage.setItem('name','Nikhil') 


Read Data:
Syntax : localStorage.getItem('key')
Example : localStorage.getItem('name') 

Update Data:
Syntax : localStorage.setItem('key','value')
Example : localStorage.setItem('name','Niks') 

Delete Data:
Syntax : localStorage.removeItem('key')
Example : localStorage.removeItem('name') 

Delete All Data From Local Storage:
Syntax : localStorage.clear()

Session Storage :
Session storage will store data only until the window or the tab in the browser is closed, which means the data will be available only for the particular session.

Add Data:
if(window.sessionStorage)
{
          //web storage supported by browser 
          sessionStorage.setItem('name','value')   //Syntax
          sessionStorage.setItem('name','Nikhil') //Example
}
else
{
          // Use cookies
}

Update Data:
if(window.sessionStorage)
{
          //web storage supported by browser
          sessionStorage.setItem('name','value') //Syntax
          sessionStorage.setItem('name','Niks')  //Example
}
else
{
          // Use cookies
}

Delete Data:
Syntax : sessionStorage.removeItem('key')
Example : sessionStorage.removeItem('name')

Delete All Data From Session Storage:
Syntax : sessionStorage.clear()

How to write Unit Tests in .net

Unit tests are automated tests that verify the behavior code like methods and functions. Writing unit tests is crucial to clean coding, as they help ensure your code works as intended and catches bugs early in the development process. I can share some tips for writing effective unit tests: Write tests for all public methods Every public method in your code should have a corresponding unit test. This helps ensure that your code behaves correctly and catches any unexpected behavior early. public class Calculator { public int Add(int a, int b) { return a + b; } } [TestClass] public class CalculatorTests { [TestMethod] public void Add_ShouldReturnCorrectSum() { // Arrange Calculator calculator = new Calculator(); int a = 1; int b = 2; // Act int result = calculator.Add(a, b); // Assert Assert.AreEqual(3, result); } } Test boundary conditions  Make sure to test boundary conditions, such a...
