Specification-Based Testing: Analyze boundaries

When conducting specification-based tests, analyzing boundaries is crucial. Boundaries, such as inclusive and exclusive intervals, often harbor bugs. For instance, in the CHIP-8 emulator code, the boundary condition for the carry flag at exactly 255 requires thorough testing. Testing exact, minus one, and plus one boundary values is essential to identify potential bugs and clarify code behavior.

Simplify Your Tests and Save Time: A Guide to Test Data Builders

Test data builders provide a solution to the time-consuming and complex task of setting up test scenarios. By pre-populating domain objects with valid data, developers can easily modify and reuse data for their tests. This technique not only simplifies the test setup process but also significantly improves the readability and maintainability of the test code, ultimately enhancing the developer experience.
