A software development methodology is a framework that is used to structure, plan, and control the life cycle of a software product. Common methodologies include waterfall, prototyping, iterative and incremental development, spiral development, agile software development, rapid application development, and extreme programming.
Software assurance initiatives are programs and activities designed to ensure the quality, reliability, and security of software systems. These initiatives are important because software is used in a wide range of applications, from business operations to critical infrastructure, and defects or vulnerabilities in software can have serious consequences.
Software testing can also be performed by non-dedicated software testers. In the 1980s, the term software tester started to be used to denote a separate profession. Notable software testing roles and titles include: [65] test manager, test lead, test analyst, test designer, tester, automation developer, and test administrator. [66]
Clover also allows testing time to be reduced by only running the tests that cover the application code that was modified since the previous build. This is called Test Optimization [ 19 ] and can lead to huge drops in the amount of time spent waiting for automated tests to complete.
This article discusses a set of tactics useful in software testing.It is intended as a comprehensive list of tactical approaches to software quality assurance (more widely colloquially known as quality assurance (traditionally called by the acronym "QA")) and general application of the test method (usually just called "testing" or sometimes "developer testing").
Specify test data needed and charter effort (often overlooked, but vital to carrying out a valid performance test). Develop proof-of-concept scripts for each application/component under test, using chosen test tools and strategies. Develop detailed performance test project plan, including all dependencies and associated timelines.
It ensures the continuing function of a piece of software under unforeseen circumstances. Defensive programming practices are often used where high availability, safety, or security is needed. Defensive programming is an approach to improve software and source code, in terms of: General quality – reducing the number of software bugs and problems.
Test-driven development (TDD) is a way of writing code that involves writing an automated unit-level test case that fails, then writing just enough code to make the test pass, then refactoring both the test code and the production code, then repeating with another new test case.
