Pearson CTFL-Foundation New Attempt

The main objective during development testing is to cause as many failures as possible to identify defects in the software. This proactive approach ensures that defects are discovered and addressed early in the development process, improving the overall quality and reliability of the final product​​.

The typical order of testing phases starts with unit testing, where individual components are tested in isolation. This is followed by system testing, where the integrated system is tested as a whole. Acceptance testing is then conducted to ensure the system meets the business requirements and is ready for deployment. Finally, maintenance testing is performed after the system is in production to ensure it continues to function correctly and to address any issues that arise.

The amount of testing that is considered enough depends on various factors, including the level of risk associated with the application, industry standards, contractual obligations, and specific requirements. It is a risk-based decision that balances the need for thorough testing with time and resource constraints. Reference: ISTQB CTFL Syllabus V4.0, Section 5.2.2​​.

A test case defines the expected result of a test. The ISTQB CTFL syllabus v4.0 explains that a test case includes a set of input values, execution preconditions, expected results, and execution postconditions developed for a particular objective or test condition​​.
