What is software testing ?
Verification :
There are two basics of software testing
1. Blackbox Testing :
2. Whitebox Testing :
Types:
There are many types of testing like as below
Unit Testing :
Integration Testing:
Functional Testing:
System Testing:
Performance Testing:
Usability Testing:
Acceptance Testing
Regression Testing
Beta Testing
- It is the process of evolution a software item to detect difference between given input and expected output , also to assess the feature of a software system.
- Testing assesses the quality of the product.
- It should be done in development phase.
- It is a verification and validation process.
Verification :
- It is the process to make sure the product satisfies the conditions imposed at start of the development phase.
- To make sure the product behaves the way we want.
Validation :
- It is the process to make sure the product satisfies the specified requirements at end of the development phase.
- To make sure the product is built as per customer requirement.
There are two basics of software testing
1. Blackbox Testing :
- It is a testing technique that ignores internal mechanism of the system and focusses on the output generated against any input and execution of the system.
- It is often used for Validation.
2. Whitebox Testing :
- It is a testing technique that takes into account the internal mechanism of the system.
- It is often used for Verification.
Types:
There are many types of testing like as below
Unit Testing :
- It is the testing of an individual unit or group of related units.
- It is done by programmer to test that the unit he has implemented is producing expected output against input.
- It falls under class of whitebox testing.
Integration Testing:
- It is testing in which the group of components are combined to produce the output.
- It is also interaction between hardware and software is tested if hardware and software components have any relation.
- It may fall both blockbox and whitebox testing.
Functional Testing:
- It is the testing to ensure that the specified fuctionalities required in the system requirements works.
- It falls under class of Blackbox testing.
System Testing:
- It is the testing to ensure that by putting the software in different environments (diff OS) it still works.
- It is done with full system implementation and environments.
- It falls under class of Blackbox testing.
Performance Testing:
- It is the testing to assess the speed and effectiveness of the system and to make sure it's generating results in
- specified time as an in performance requirements.
- It falls under class of Blackbox testing.
Usability Testing:
- It is performed to the perspective of the client , to evaluate how the GUI is user-friendly .How easily can the client learn? After learning how to use, how proficiently can the client perform? How pleasing is it to use its design?
- It falls under class of Blackbox testing.
Acceptance Testing
- It is often done by the customer to ensure that the delivered product meets the requirements and works as the customer expected.
- It falls under the class of black box testing.
Regression Testing
- It is the testing after modification of a system, component, or a group of related units to ensure that the modification is working correctly and is not damaging or imposing other modules to produce unexpected results.
- It falls under the class of black box testing.
Beta Testing
- It is the testing which is done by end users, a team outside development, or publicly releasing full pre-version of the product which is known as beta version. The aim of beta testing is to cover unexpected errors.
- It falls under the class of black box testing.
