Traditional testing methodology refers to the conventional approach to software testing that involves following a pre-defined set of testing procedures and protocols. Synonyms for traditional testing methodology include classic testing, legacy testing, old-school testing, and traditional quality assurance. Other related phrases include structured testing, manual testing, and waterfall testing. While these methods are still commonly used in many organizations, there has been a trend toward agile testing, which involves a more flexible, iterative approach to software development and quality assurance. Other alternative testing methodologies include exploratory testing, shift-left testing, and regression testing, all of which aim to improve the efficiency and effectiveness of the testing process.
