Question

I am new to the Unit Testing And using Nunit i dont know how to pass this exception but there is an AssertionUnhandled Exception.

I am doing

Assert.AreEqual(exists, 1 == (int)ExecScalar(string.Format("SELECT COUNT(*)    
FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = '{0}{1}' AND TABLE_SCHEMA ='{2}'", 
            (audit ? DBHelper.AuditTablePrefix : ""), tableName, schema)));

Here exists = true and in my case other comes to 1==0 so it says Expected True but false.

So what should i do because i dont know how can i move further.

Thanks in advance.

Looks like you are trying to ensure that particular query returns 1 as tables count,
I would suggest you to wrap such complex query in Assert.DoesNotThrow() and use Assert.AreEqual() to compare two values:

int numberOfTables = -1;

Assert.DoesNotThrow(() => numberOfTablesRaw = 
             (int)ExecScalar(string.Format(
             "SELECT COUNT(*) FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = '{0}{1}' AND TABLE_SCHEMA ='{2}'",  
             (audit ? DBHelper.AuditTablePrefix : ""), 
              tableName, 
              schema)));

Assert.AreEqual(1, numberOfTables);
