To send ether to your Solidity test contract, it should have a public function that returns uint, called initialBalance in that contract. This can be written directly as a function or a public variable.

Your test contract can then use that ether to script ether interactions within your contract under test. Note that initialBalance is optional and not required. For example, take a look at the following code:

import "truffle/Assert.sol"; import "truffle/DeployedAddresses.sol"; import "../contracts/MyContract.sol"; contract TestContract {  // Truffle will send the TestContract ...
