How Does Continuous Testing Differ from
Traditional Testing?
Continuous testing and traditional testing represent two distinct approaches
to software quality assurance, each with its unique characteristics,
methodologies, and outcomes. Here's an in-depth look at how they differ:
1. Timing and Frequency of Testing:
● Traditional Testing: In traditional software development models like
Waterfall, testing typically occurs after the development phase is
complete. This means testing is often a discrete phase that happens
towards the end of the project lifecycle. As a result, defects are
identified late, making them more costly and time-consuming to fix.
● Continuous Testing: In contrast, continuous testing is integrated
throughout the development lifecycle. Automated tests are executed
continuously at every stage, from development to production. This
approach ensures that code is tested as soon as changes are made,
providing immediate feedback to developers.

8. 2. Feedback Loop:
● Traditional Testing: The feedback loop in traditional testing is
relatively long. Developers may not receive feedback on code quality
until weeks or even months after writing the code. This delay can lead
to a backlog of defects that need to be addressed late in the
development process.
● Continuous Testing: Continuous testing provides a much shorter
feedback loop. Automated tests run with every code commit,
delivering instant feedback on the impact of changes. This immediate
feedback helps developers quickly identify and fix issues, maintaining
the quality of the codebase.
3. Test Coverage and Automation:
● Traditional Testing: Traditional testing often relies heavily on manual
testing, which can be time-consuming and prone to human error.
While automated tests may be used, they are usually not as
extensively integrated into the development process.
