Manual testing takes more effort and cost than automated testing. It is more boring and provides limited visibility for stakeholders. Automated tests can test single units, are reusable, and provide a safety net for refactoring. They also ensure all tests are run, drive clean design, and do not create code clutter like manual tests. An initial learning curve and questions around organization and reuse may prevent developers from writing automated tests, but designating responsibility and learning tools can help overcome these issues.
