Software testing is the act of checking whether software satisfies ... inferences about intended or expected purpose, ... "Seven Principles of Software Testing" (PDF).
The standard formed part of the training syllabus of the ISEB Foundation and Practitioner Certificates in Software Testing promoted by the British Computer Society. ISTQB, following the formation of its own syllabus based on ISEB's and Germany's ASQF syllabi, also adopted IEEE 829 as the reference standard for software and system test documentation.
Unit testing, a.k.a. component or module testing, is a form of software testing by which isolated source code is tested to validate expected behavior. [ 1 ] Unit testing describes tests that are run at the unit-level to contrast testing at the integration or system level.
System testing can detect defects in the system as a whole. [citation needed] [1] System testing can verify the design, the behavior and even the believed expectations of the customer. It is also intended to test up to and beyond the bounds of specified software and hardware requirements. [citation needed]
A load test is usually conducted to understand the behavior of the system under a specific expected load. This load can be the expected concurrent number of users on the application performing a specific number of transactions within the set duration. This test will give out the response times of all the important business critical transactions.
A software requirements specification (SRS) is a description of a software system to be developed.It is modeled after the business requirements specification.The software requirements specification lays out functional and non-functional requirements, and it may include a set of use cases that describe user interactions that the software must provide to the user for perfect interaction.
Dynamic testing involves running the software. Static testing includes verifying requirements, syntax of code and any other activities that do not include actually running the code of the program. Testing can be further divided into functional and non-functional testing. In functional testing the tester would check the calculations, any link on ...
White-box testing (also known as clear box testing, glass box testing, transparent box testing, and structural testing) is a method of software testing that tests internal structures or workings of an application, as opposed to its functionality (i.e. black-box testing). In white-box testing, an internal perspective of the system is used to ...
