A test strategy is an outline that describes the testing approach of the software development cycle.The purpose of a test strategy is to provide a rational deduction from organizational, high-level objectives to actual test activities to meet those objectives from a quality assurance perspective.
The test plan could come in the form of a single plan that includes all test types (like an acceptance or system test plan) and planning considerations, or it may be issued as a master test plan that provides an overview of more than one detailed test plan (a plan of a plan). [51] A test plan can be, in some cases, part of a wide "test strategy ...
Shift-left testing [1] is an approach to software testing and system testing in which testing is performed earlier in the lifecycle (i.e. moved left on the project timeline). It is the first half of the maxim "test early and often". [2] It was coined by Larry Smith in 2001. [3] [4]
Model-based testing is an application of model-based design for designing and optionally also executing artifacts to perform software testing or system testing. Models can be used to represent the desired behavior of a system under test (SUT), or to represent testing strategies and a test environment. The picture on the right depicts the former ...
Test Driven Development (TDD) is a software development approach where tests are written before the actual code. It offers several advantages: Comprehensive Test Coverage: TDD ensures that all new code is covered by at least one test, leading to more robust software.
Test coverage in the test plan states what requirements will be verified during what stages of the product life. Test coverage is derived from design specifications and other requirements, such as safety standards or regulatory codes, where each requirement or specification of the design ideally will have one or more corresponding means of verification.
Risk-based testing uses risk (re-)assessments to steer all phases of the test process, i.e., test planning, test design, test implementation, test execution and test evaluation. [4] This includes for instance, ranking of tests, and subtests, for functionality; test techniques such as boundary-value analysis , all-pairs testing and state ...
Development, testing, acceptance and production (DTAP) [1] [2] is a phased approach to software testing and deployment. The four letters in DTAP denote the following common steps: Development: The program or component is developed on a development system. This development environment might have no testing capabilities.
