minitest.cr

Directly ports Ruby's Minitest syntax, making it easy for developers with Ruby experience to write tests using assertions like assert_equal and spec blocks, as shown in the unit test and spec examples.

Offers both class-based unit tests with test_ methods and behavior-driven spec syntax with describe/it blocks, allowing flexibility in testing style, evidenced by the README's separate examples for each approach.

Enables running specific tests by name or regex via command-line flags like -n, such as 'crystal run test.cr -- -n /will/', for focused development and debugging.

Follows the original Minitest's philosophy of minimalism, resulting in a lightweight framework with less overhead, as emphasized in the project's rationale and simple setup.
