Perfect delivery is your master key to ground-breaking success in the world of business. Most of the corporate world is using digital technology/solutions as a key to deliver perfection. Let’s not waste any time and come to the point straightaway. Most of the businesses are going digital. Considering this, what is the key to success of your business? The answer to this question is not very difficult.

Software testing services is the right answer. Every business makes use of some specific and productive business software. A successful software acts as a powerful spine for your business and paves a roadway towards ground-breaking corporate success. What is a software? What makes any software successful or productive for any business? These are two very important questions that arise at this stage.

Talking about software, their types, development lifecycle, will help you understand Software testing and everything related to it to perfection.

1. What is a software? What are the types of software?
Software is a combination of various programs and specific operating information. It is specifically used by a computer or a smartphone for catering to the needs of a user. There are four different kinds of software.
• System Software.
• Application Software.
• Custom Software
• Packaged Software

What is the difference between the types of software mentioned above? Let’s learn about this difference to learn about software testing and everything related to it. Let’s define all of them one by one for you.

A. System Software:
System software is a combination of programs particularly dedicated to the management of vital internal components of any computer system such as:
1. The operating system.
2. Disk Operating System.
3. Utilities for perfect management of system files.
4. Device Drivers.

B. Application Software:
Application programs are also called productivity programs for their efficiency. End User Programs is also the name of application programs. Why application programs are called End User Programs? Application programs are called End User Programs or Productivity programs because they are dedicated to performing various day-to-day tasks for users. These tasks may include the creation of documents, spreadsheets, publications, databases, conducting online researches for something, preparing designs of graphics, handling various business processes on digital front, sending e-mails and even enjoying video games for mental recreation after spending a tiresome day in the office. Every application software is specific to the task it is specifically designed to perform under various kinds of circumstances.

C. Custom Software:
Some of the application software are specifically licensed to make sure that every user has to buy it for using it. Some of the software are open sources applications. These open source software applications are specifically designed or edited for every organization to meet its needs. Such type of software are called custom software.

D. Packaged software:
Packaged software is always ready for sale, lease or public use. It is also popularly known as a software package which is often programmed to perform similar functions and includes a lot of similar features. Packaged software are often bundled together as a set of particular software programs. Packaged software are often ready-made and available for use.

2. Software Development Lifecycle:
In general terms, it can be called as System Development Lifecycle. It is an integral and the most important component of any software development process. It is systematic structure imposed on the development process of any software product. It is a kind of model which particularly consists of several models for this kind of processes. All of the models are specifically for describing approaches to a broad range of tasks or activities that take place during the developmental phase of any software.

3. Software Development Processes and Models:
Most of the renowned software development and testing companies in India focus on the implementation of process methodologies. The entire market is an ocean of such models. Some of them are listed below:
• ISO 900
• ISO 15504
• Six Sigma

There are plenty of such models. But Capability Maturity Model (CMM) is the most popular process methodology or model. However, the development of any successful software is the result of the way any organization defines and executes all of its processes. The success of any software development process also depends on the accuracy of any company’s models. This entire procedure and its accuracy is key to the independence of accuracy assessments for grading any organization.

As for Software development lifecycle process models, there are mainly two types of process models. Following are the two types of software development lifecycle process models:
• Waterfall Process Model
• Iterative Process Model
• Agile Process Model
• RAD Models
• Incremental Model
• Spiral
• Prototype
• V- Model

Some Vital Components of Software Development Process:
It is not easy to execute any software process model without the contribution of the following software development lifecycle components:
• Analysis of requirements
• Specifications
• Architecture of software
• Implementation
• Documentation
• Training and support
• Maintenance
• Testing

All of these components play a vital role during the developmental process of any software and play a huge role in the success of any software. Testing is usually the last process which is performed to ensure the accuracy of results for exceeding the requirements and expectations of clients. It is performed for the purpose of finding bugs or any possibility of any kind of problem in the software. Almost every company has its own rigorous software testing procedure in place.

Software Testing:
Software testing is a rigorous and very complex process followed for executing a program or an application for finding any kind of bug in it. All of the software testing services experts execute this process for the validation and verification of any newly developed software. The main objective of software testing is quality assurance.

Ensuring the fulfillment of all of the technical and business requirements is the biggest objective of software testing. It makes sure that your software works smoothly and it is ready to be used with the same specifications.
Let’s break Software testing into the following parts and make it easy for you to understand.

Process and all lifecycle activities are an integral part of the entire software testing procedure. What is process? What is the difference between process and all lifecycle related activities? The answer to these two questions is as simple as ABC!
In simple words, the entire software testing procedure is a kind of technically complex process instead of a single activity. Software testing is rigorously conducted throughout the software development lifecycle.

It is always wise to be proactive and implement the best technical approaches and for designing tests during the initial stages of the software development lifecycle. Such a wise approach is very useful for preventing defects in the code. It is also called as “varying the test basis via the test design. All of the documents stating requirements and design specifications etc. are an important part of Software testing procedure. There are a number of best software testing companies in India.

Types of software Testing:
Software testing is a vast field in itself. Some of the experts even recommend this field should be open to scientific researches for more accuracy in performance. There are various types of software testing. Some of them are listed below:
1. Static testing
2. Dynamic testing
