Integration testing involves testing how different parts of your smart contract interact with each other and with external systems. This type of testing helps identify issues that might not be apparent in isolated unit tests.
Example: Testing how a smart contract interacts with an oracle to fetch external data and ensuring the data is processed correctly.
Fuzz Testing
Fuzz testing involves providing invalid, unexpected, or random data as inputs to a smart contract to see how it handles these scenarios. This technique can uncover vulnerabilities that would otherwise go unnoticed.
Example: Feeding malformed transaction data to see if the contract handles it gracefully or crashes.
Property-Based Testing
Property-based testing is a method where tests are defined by properties that the code should satisfy. This approach ensures that the contract behaves correctly under a wide range of conditions.
Example: Ensuring that a contract’s balance always reflects the correct total amount of tokens held, regardless of the sequence of transactions.
State Machine Testing
Blockchain transactions fundamentally alter the state of the network. State machine testing verifies that the smart contract correctly updates the state in accordance with the defined rules.
Example: Testing all possible states of a contract to ensure that it transitions between states correctly and that it handles edge cases properly.
