It can test paths within a unit, paths between units during integration, and between subsystems during a system–level test. Though this method of test design can uncover many errors or problems, it might not detect unimplemented parts of the specification or missing requirements. Techniques used in white-box testing include: [32] [34]
System testing, a.k.a. end-to-end (E2E) testing, is testing conducted on a complete software system. System testing describes testing as at the system level to contrast to testing at the integration or unit level. System testing often serves the purpose of evaluating the system's compliance with its specified requirements [citation needed ...
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

System suitability – A test run each time an analysis is performed to ensure the test method is acceptable and is performing as written. This type of check is often run in a QC Lab. Usually, system suitability is performed by analyzing a standard material (House standard or reference standard) before the unknowns are run in an analytical method.
v. t. e. In software development, functional testing is a form of software system testing that verifies whether software matches its design. Generally, functional testing is black-box meaning the internal program structure is ignored (unlike for white-box testing). [1] Functional testing can evaluate compliance to functional requirements. [2 ...
t. e. 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 ...
Unit testing allows the programmer to refactor code or upgrade system libraries at a later date, and make sure the module still works correctly (e.g., in regression testing). The procedure is to write test cases for all functions and methods so that whenever a change causes a fault, it can be identified quickly.
Agile testing is a software testing practice that follows the principles of agile software development. Agile testing involves all members of a cross-functional agile team, with special expertise contributed by testers, to ensure delivering the business value desired by the customer at frequent intervals, working at a sustainable pace.
