Structuring Test Files

Organize test files to mirror the lib directory structure to maintain predictability.

• Place all test code within the test directory at the root of the package.
• Append _test.dart to the end of all test file names (e.g., lib/src/utils.dart should be tested in test/src/utils_test.dart).
• If writing integration tests, place them in an integration_test directory at the root of the package.

Writing Tests

Utilize package:test as the standard testing library for Dart applications.
