PHPUnit necessitates the activation of the dom and json extensions, which are typically enabled by default, alongside the pcre, reflection, and spl extensions that are also standard and cannot be disabled without modifying PHP's build system or source code. Additionally, to generate code coverage reports, the Xdebug extension (version 2.7.0 or newer) and the tokenizer extension must be present, while the ability to create XML reports relies on the xmlwriter extension. Writing unit tests is fundamentally a best practice for developers to detect and resolve bugs, refactor code, and provide documentation for a unit of software being tested. Ideally, unit tests should encompass all potential execution paths within a program to maximize effectiveness. Generally, a single unit test is aligned with one specific path in a particular function or method. Nonetheless, it is important to recognize that a test method may not function as a completely isolated or independent unit, as there can often be subtle dependencies between various test methods that stem from the underlying implementation of a test scenario. This interconnectedness can sometimes lead to challenges in maintaining test integrity and reliability.
