Contract Unit
“`soliditypragma solidity ^0.8.0;
contract Unit {
// Define a function to demonstrate unit testing function addTwoNumbers(uint a, uint b) public pure returns (uint) { return a + b; }}“`
Explanation:
- The
unit
contract defines aaddTwoNumbers
function that takes two unsigned integersa
andb
as input and returns their sum. - The
pure
keyword indicates that the function does not modify the contract’s state and can be safely copied into the bytecode. - The function’s return type is
uint
, which is an unsigned integer.
Testing the function:
To test the addTwoNumbers
function, you can use a testing framework like Truffle or Hardhat. Here’s an example test case:
“`import “@openzeppelin/contracts/test/contracts/unit.sol”;
contract UnitTest is unittest.Contract {
function testAddTwoNumbers() public { Unit unitContract = new Unit(); uint result = unitContract.addTwoNumbers(5, 10); assert.equal(result, 15); }}“`
Note:
This is just an example contract and test case. You can modify the code to suit your own needs.
