TopCoder offers a variety of testing options for any application:

• Test Scenarios - Given requirements and some form of prototype, members will draft a detailed set of test scenarios to validate that requirements are met and the application functions as expected.
• Test Automation - Given a set of test scenarios, members will automate tests to enable fast and repeatable quality assurance.
• TopCoder Bug Hunt Competitions - Concerned about bugs that slipped through the cracks? Don't be! With a Bug Hunt, members carefully examine every aspect of your application to find the bugs that the planned tests missed.
