PCOV Reviews

PCOV Description

A standalone driver compatible with CodeCoverage for PHP is known as PCOV. When PCOV is not configured, it will search for directories named src, lib, or app in the current working directory sequentially; if none of these are located, it defaults to using the current directory, which can lead to inefficient use of resources by storing coverage data for the entire test suite. If the PCOV configuration includes test code, it is advisable to utilize the exclude command to optimize resource usage. To prevent the unnecessary allocation of additional memory arenas for traces and control flow graphs, PCOV should be adjusted based on the memory demands of the test suite. Furthermore, to avoid table reallocations, the PCOV setting should exceed the total number of files being tested, including all test files. It's important to note that interoperability with Xdebug is not achievable. Internally, PCOV overrides the executor function, which can disrupt any extension or SAPI that attempts to do the same. Notably, PCOV operates at zero cost, allowing code to execute at full speed, thus enhancing performance without additional overhead. This efficiency makes it a valuable tool for developers looking to maintain high performance while ensuring effective code coverage.
