What are common mistakes developers make with assertions?

Assertions are a powerful tool for developers, but they can often be misused or misunderstood. Here are some common mistakes developers make with assertions:

  • Using Assertions for Control Flow: Assertions should not be used to replace proper error handling. They are meant for testing assumptions, not managing normal operational flow.
  • Relying on Assertions in Production: Assertions can be disabled at runtime. Relying on them for critical business logic can lead to unexpected behavior.
  • Neglecting to Document Assertions: Always document what the assertion is checking. Without documentation, other developers may not understand the purpose of the assertion.
  • Overusing Assertions: Too many assertions can clutter the code and reduce readability. Use them judiciously to maintain clarity.
  • Making Assertions Without Context: Ensure that the context in which the assertion is made is clear. This will help debug when assertions fail.
