+/// `MockProvider` is a mock Ethereum provider that can be used for testing purposes.
+/// It allows to simulate Ethereum state and behavior, by explicitly instructing
+/// provider's responses on client requests.
+///
+/// This can be useful for testing code that relies on providers without the need to
+/// connect to a real network or spend real Ether. It also allows to test code in a
+/// deterministic manner, as you can control the state and behavior of the provider.
+///
+/// In these examples we use the common Arrange, Act, Assert (AAA) test approach.
+/// It is a useful pattern for well-structured, understandable and maintainable tests.
