The Gnosis MockContract is a smart contract enabling developers to quickly mock contract interactions for unit tests.
It enables developers to
- Make dependent contracts return predefined values for different methods and arguments
- Simulate exceptions such as revert and outOfGas
- Assert on how often a dependency is called
The MockContract facilitates these features without requiring any separate test contracts.
Check out the repo: https://github.com/gnosis/mock-contract
Extend the functionality of the MockContract to partially matching arguments.
- Develop a framework allowing developers to define partially matching calldata for specific methods.
Defining partially matched call data should look similar to:
const particallyMatchedCalldata = contract.methods.methodName(
accounts, ANY, ..., ANY
Here, ANY would be some sort of constant defined in the smart contract.
- Write the logic for the MockContract to expose predefined returns to the partially matched calldata.
It is expected that the following functions for partially matched calldata are provided:
function givenPartialCalldataReturn(bytes calldata call, bytes calldata response) external;
function givenPartialCalldataReturnBool(bytes calldata call, bool response) external;
function givenPartialCalldataReturnUint(bytes calldata call, uint response) external;
function givenPartialCalldataReturnAddress(bytes calldata call, address response) external;
function givenPartialCalldataRevert(bytes calldata call) external;
function givenPartialCalldataRevertWithMessage(bytes calldata call, string calldata message) external;
function givenPartialCalldataRunOutOfGas(bytes calldata call) external;
They should enable the same functionality on partially matching calldata as the current respective functions with the same function names, but without the word "Partial".
- Make sure the invocation count functions are still returning the expected numbers
function invocationCount() external returns (uint);
function invocationCountForMethod(bytes calldata method) external returns (uint);
function invocationCountForCalldata(bytes calldata call) external returns (uint);
- Current naming conventions need to be preseved
- All functionality must have 100 % line and branch coverage
- The [solidity style guide](https://solidity.readthedocs.io/en/v0.5.3/style-guide.html) must be considered and code must be linted
Additional GNO can be tipped according to the level of technical implementation
