How does the ability to view code contribute to creating automated tests?

The ability to view the code (for example, the application's source code or the tested module) significantly facilitates the creation of automated tests for several reasons:

• Understanding the logic: Knowing how the code works allows the tester to identify critical areas and scenarios that require verification.
• Choosing entry points: You can select methods or functions to test directly, especially when writing unit tests.
• Defining boundary conditions: Analyzing the code helps identify possible edge cases and errors that need to be covered by tests.
• Simplifying debugging: When problems arise in tests, you can quickly find the cause by examining the code.

Thus, access to the code improves the quality and completeness of automated tests, making them more targeted and effective.
