How has support for test discovery (prove) changed across recent Perl versions?

Support for test discovery in Perl, particularly through the use of the `prove` command, has evolved significantly across various versions of Perl. The `prove` command is utilized for running test scripts and has progressively enhanced its functionalities to improve the testing workflow for developers.

Test Discovery in Recent Perl Versions

In earlier versions of Perl, using `prove` was limited and often required explicit specifications for locating and running tests. However, with updates to the `Test::Harness` and associated modules, recent versions of Perl have streamlined this process, making it more intuitive and efficient.

Key Changes

• Improved test file handling that allows for better identification of test scripts.
• Enhanced support for directory structures, allowing for recursive testing of nested directories.
• Integration with additional testing frameworks that can be discovered automatically.

Example Usage

The following is an example of using `prove` to run tests in a directory:
