Software:
Software is a collection of programs, data and instructions that tell a Computer how to perform specific tasks.
It is the non-physical(intangible) component of a Computer system that enables hardware to function.
Software can be categorized into two types
System Software:
These softwares are used to provide interface between the system components.
Application Software:
These are developed based on client business needs in order to perform their business activities
Application s/w divided into two types.
a. Product Based :-
When we develop an application based on standard requirements, it can be sold to any customer in the market.
b. Project Based :-
When an application is developed based on specific client requirements, it is delivered exclusively to that client.
It is a process used to identify the correctness and completeness and to measure the quality of a developed software application.
- Software testing plays a key role in delivering reliable applications and minimizing project maintenance costs.
- The primary objective pf software testing is defect identification, which in turn enhances software quality when resolved.
Defect :- It is a variation between the expected result and the actual result produced by the application under test.
- Defect may also be known as a bug.
Correctness :- Validating that the implemented functionality performs as expected through operational testing.
Completeness :- Ensure that all client business requirements are addressed through the application's functionalities.
- Software testing, in simple terms, involves both verification and validation.
- According to the development team, an application is qualified as a quality product when it meets all client requirements.
- According to the client or end user, an application is considered high quality when it is fit for use and aligned with business requirements
Following are the major factors depends software quality:
- Budget or Cost
- In Time Release
- Reliability
1. Meet client requirements in terms of functionality
2. Meet Client Expectations
Software Testing Methods :-
- Manual Testing
- Automation Testing
- Performance Testing
- Security Testing
Manual Testing :-
Manual testing involves verifying the application's actual behavior by performing operations or transactions without the use of automation tools. Test engineers prepare test cases to validate the application.
Advantages : Simple & Easy
Disadvantages :
- Time Consuming
- Human Erros
- In Efficient Results some time
Automation Testing :-
