Kas võiks selgitada, mida mõistetakse lepinguna tarkvaraarenduse kontekstis?

In the context of software development, a contract is an agreement between system components about how they should interact. It defines the obligations and guarantees of each party.

For example, a contract may describe:

• What input data a function or module accepts.
• What outputs or effects are guaranteed.
• Preconditions (what must be true before the call).
• Postconditions (what will be true after execution).

This helps improve the reliability and predictability of the code, making testing and maintenance easier.
