What is the difference between System Test Case and Functionality Test Case ?

What is Test case

A test case is a set of conditions or variables under which a tester will determine whether a system under test satisfies requirements or works correctly.
The process of developing test cases can also help find problems in the requirements or design of an application.

Difference between System and Functional Test Case

System Testing

System testing aims to figure out whether the whole system fulfills the requirements given to it.
System Test Case will be developed to validate the System as a whole End-to-end, while combining it with the required HW, Database, Networking and any other connections such as Printers, Fax or any other external. Supporting SW application.
Here, while an input is given to the System, the System’s behavior to handle the input data and its final expected output will be verified.
System testing take a look at the typical stop product. which includes each unmarried module, interface and every minute details along with all inner and external additives of the system.
Gadget checking out fundamental reason is to find out whether or not the complete gadget fulfills the requirements as given to it.
Using tools might be powerful for system testing.
Device trying out describes how right the product works.

System testing

Functional Testing

Functional testing aims to figure out whether given functionality works as specified.
Functional Test Cases whole be developed to validate the Application according to the functionality demanded by the client or provided in the SRS.
The input is given to the application, the application behavior to handle the input data and its final expected output will be verified.
Useful checking out take a look at the functionalities of the product. which incorporates strain, load, safety, overall performance and many others.
Manual checking out or automation gear may be used for functional checking out.
Functional checking out describes what the product does.

What is Deployment ?

Deployment includes all the process required for preparing a software application to run and operate in a specific environment. It involves installation, configuration, testing and making changes to optimize the performance of the software. It can either be carried out manually or through automated systems.
The advantages of Deployment,
- Time saving
- Enhance security
- Monitor User Actions
- Effective software updates

What is the purpose of method overriding in java where we are completely re-defining a inherited method ?

Editor — Tue, 13 Jul 2021 23:07:03 +0000

Method overriding in java

Declaring a method in sub class which is already present in parent class is known as method overriding.
Overriding is done so that a child class can give its own implementation to a method which is already provided by the parent class.
In this case the method in parent class is called overridden method and the method in child class is called overriding method.

Purpose of method overriding

The main purpose of method overriding is that the class can give its own specific implementation to a inherited method without even modifying the parent class code.
This is helpful when a class has several child classes, so if a child class needs to use the parent class method, it can use it and the other classes that want to have different implementation can use overriding feature to make changes without touching the parent class code.

Difference between Redefining and Overriding

The term “redefinition” isn’t usually used with regards to Java methods and inheritance. There are two terms that are commonly used: “override” and “overload.”
Redefining and Overriding comes with in the same scenarios. Only difference is that if methods used are Static, its redefining.For Example,

Overriding

Class A
{
      public void show(){
             SOP("class a");
        }
   }

   Class B extends A
{
     public void show(){
         SOP("class B");
     }
   }

Redefining

 
Class A
{
      public static void show(){
             SOP("class a");
        }
   }

   Class B extends A
{
     public static void show(){
         SOP("class B");
     }
   }

Note: Static methods looks as if they are over-rided but they are actually redefined.

Redefining is with Static Methods.
Static methods are associated with Class and not with Object, so we do not override as per instance for run-time.
In case of static we are just redefining the method.

Re-defining a Inherited Method

Re-defining involves a inherited method like Replacement and Refinement

Replacement

**Replacement** is the case in which child class is overriding

The inherited method of parent class with a behavior(functionality) which is completely different from corresponding parent method and a sign for this process is not calling super.method() in the body of child method.

Refinement is the case in which child is overriding inherited

The method from parent with a functionality related to parent method functionality, sign of this process is calling generally super.method() in the body of child method.
