Black box testing – Internal system design is not considered in this type of testing. Tests are based on requirements and functionality.
White box testing – This testing is based on knowledge of the internal logic of an application’s code – also know as glass box testing. Internal software and code working should be know for this type of testing. Tests are based on coverage of code statements, branches, paths, conditions.
Unit testing – Testing of individual software components or modules. Typically done by the programmer and not by testers, as it requires detailed knowledge of the internal program design and code. May require developing test driven modules or test harnesses.
Incremental integration testing – Bottom up approach for testing i.e continuous testing of an application as new functionality is added. Application functionality and modules should be independent enough to test separately. Done by programmers or testers.
Integration testing – Testing of integrated modules to verify combined functionality. This type of testing is especially relevant to client/server and distributed systems.
Functional testing – This type of testing ignores the internal parts and focus on the output is as per requirement or not. Black-box type testing geared to functionality requirements of an application.
System testing – Entire system is tested as per the requirements. Black-box type testing that is based on overall requirements specifications, covers all combined parts of a system.
End-to-end testing – Similar to system testing, involves testing of a complete application environment in a situation that mimics real-word use, such as interacting with a database, using network communications, or interacting with other hardware, applications, or systems if appropriate.
Sanity testing – Testing to determine if a new software version is performing well enough to accept it for a major testing effort.
Performance testing – Term often used interchangeably with ‘stress’ and ‘load’ testing. To check whether system meets performance requirements. You will use different performance and load tools to do this. Example: Jmeter.
Usability testing – User-friendliness check. Application flow is tested, can new user understand the application easily.
Install/uninstall testing – Tested for full, partial, or upgrade install/unistall processes on different operating systems under different hardware, software environment.
Recovery testing – Testing how well a system recovers from crashes, hardware failures, or other catastrophic problems.
Security testing – Can system be penetrated by any hacking way. Testing how well the system is protected against unauthorized internal or external access. Check if system, database is safe from external attacks.
Compatibility testing – Testing how well software performs in a particular hardware/software/operating system/network environment and different combinations of above.
Comparison testing – Comparison of product strengths and weaknesses with previous versions or other similar products.
Alpha testing – In house virtual user environment can be created for this type of testing. Testing is done at the end of development. Still minor design changes may be mades as a result of such testing.
Beta Testing – Testing typical done by end-user or others. Final testing before releasing application for commercial purpose.
