Solidity contract that can be used to mock contract dependencies during testing. Currently supports mocking the following
Solidity types: uint256, bytes32, bool
When writing tests for a contract function that depends on values returned from a dependency contract:
it("test", async () => {
const mock = await GenericMock.new()
// Use the mock's address as the address of the dependency contract for the contract under test
// This will vary depending on how the dependency injection takes place, but the address might be set
// in the constructor of the contract under test
// Set mock return value
await mock.setMockUint256(functionSelector("foo()"), 5)
})
When writing tests for a contract function that can only be called by a whitelisted address:
it("test", async () => {
const mock = await GenericMock.new()
// Use the mock's address as the address of the dependency contract for the contract under test
// This will vary depending on how the dependency injection takes place, but the address might be set
// in the constructor of the contract under test
await mock.execute(contractUnderTest.address, functionSelector("bar()"))
})
See test/GenericMock.js for an example.
