What is software
testing? What are the different types of testing?
Software Testing
Software testing is the process of evaluation a software item to detect
differences between given input and expected output. Also to assess the feature
of A software item. Testing assesses the quality of the product. Software
testing is a process that should be done during the development process. In
other words software testing is a verification and validation process.
Verification
Verification is the
process to make sure the product satisfies the conditions imposed at the start
of the development phase. In other words, to make sure the product behaves the
way we want it to.
Validation
Validation is the
process to make sure the product satisfies the specified requirements at the
end of the development phase. In other words, to make sure the product is built
as per customer requirements.
Basics of software
testing
There are two basics of
software testing: blackbox testing and whitebox testing.
Blackbox Testing
Black box testing is a
testing technique that ignores the internal mechanism of the system and focuses
on the output generated against any input and execution of the system. It is
also called functional testing.
Whitebox Testing
White box testing is a
testing technique that takes into account the internal mechanism of a system.
It is also called structural testing and glass box testing.
Black box testing is
often used for validation and white box testing is often used for
verification.
Types of testing
There are many types of
testing like
- Unit Testing
- Integration Testing
- Functional Testing
- System Testing
- Stress Testing
- Performance Testing
- Usability Testing
- Acceptance Testing
- Regression Testing
- Beta Testing
Unit Testing
Unit testing is the
testing of an individual unit or group of related units. It falls under the
class of white box testing. It is often done by the programmer to test that the
unit he/she has implemented is producing expected output against given input.
Integration Testing
Integration testing is
testing in which a group of components are combined to produce output. Also,
the interaction between software and hardware is tested in integration testing
if software and hardware components have any relation. It may fall under both
white box testing and black box testing.
Functional Testing
Functional testing is
the testing to ensure that the specified functionality required in the system
requirements works. It falls under the class of black box testing.
System Testing
System testing is the
testing to ensure that by putting the software in different environments (e.g.,
Operating Systems) it still works. System testing is done with full system
implementation and environment. It falls under the class of black box testing.
Stress Testing
Stress testing is the
testing to evaluate how system behaves under unfavorable conditions. Testing is
conducted at beyond limits of the specifications. It falls under the class of
black box testing.
Performance Testing
Performance testing is
the testing to assess the speed and effectiveness of the system and to make
sure it is generating results within a specified time as in performance
requirements. It falls under the class of black box testing.
Usability Testing
Usability testing 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? This
falls under the class of black box testing.
Acceptance Testing
Acceptance testing 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
Regression testing 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
Beta testing 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.
Software Testing:
Software Testing
is a realm of activities with the objective to evaluate the capability and
capacity of the program or tool that has been developed. Since the limitation
and completeness of the software is hard to predict, software testing is still
looked at as a complex art and the complexity differs in accordance to the
compositeness of the software.
