What Assert.AreEqual(true, true); does? [closed]

Question

Can any one explain Assert.AreEqual(true, true); with proper example and explanation?

Answer 1

You can use Assertions to verify something is in a certain state. Normally you compare the actual against the excepted state.

Example usage:

• Do some steps in your application
• Gather the value of a field

• Assert that the value is indeed the value you expect

  Assert.AreEqual(Actual, Expected)

This could give an assertion failure if Actual and Expected differ. During a test run you should not have any assertion failures. :)

Asserts are often used in unit-tests and automated integration tests to give feedback or actually test something during a test run.

Answer 2

Can any one explain Assert.AreEqual(true, true)

Verifies that two specified objects are equal. The assertion fails if the objects are not equal. Displays a message if the assertion fails.

example and explanation?

Very simple NUnit test:

using System;
using NUnit.Framework;

namespace SampleUnitTest
{
  [TestFixture]
  public Class SampleTest
  {
    [Test]
    public void AddingOneAndOneResultsInTwo()
    {
      int two = 1 + 1;

      Assert.AreEqual(2, two);
    }
  }
}

Explanation is simple too, integer value two equals 2 and then method Assert.AreEqual(2, two) compares two values 2 and two. That is, two references to the same object would evaluate as being equal; two clones of a same object would evaluate as being different. Unless you overload the Equals() instance method of the class(es) those objects belong to, or the == operator for said class(es). Also, I suggest you to read official documentation and answers on stackoverflow:
