Execute the operations

Inco’s infrastructure is monitoring the operations requested over encrypted variables by the smart contracts.
Inco executes them asynchronously after the blocks containing the ops are mined. Under the hood, the Inco singleton instance on each supported chain is emitting events to request the operations (that includes encrypts, trivial encrypts, all logical and mathematical operations, and decryption requests). The solidity-based mock is using Foundry’s vm.recordLogs() function to record the pending ops.
As the events recording are consumed whenever read, there would be conflicts if you try to use recordLogs in your tests.
To simulate Inco processing the operations, which assigns to its internal value store its encrypted value to each handle, use the following cheatcode: 
processAllOperations();
This cheatcode must be called before reading the value of any encrypted variable, and performing assert statements. processAllOperations also executes any pending decryption callback.

​
Simulate Inputs

Encrypted inputs are normally generated using Inco’s JS SDK. Simulate them with the following cheatcodes:

​
For euint256

fakePrepareEuint256Ciphertext(uint256 value) returns (bytes memory ciphertext);

// example usage
token.transfer(bob, fakePrepareEuint256Ciphertext(1 ether));

​
For ebool

fakePrepareEboolCiphertext(bool value) returns (bytes memory ciphertext);

// example usage
someContract.setActive(fakePrepareEboolCiphertext(true));

​
Simulate decryption

Allowed accounts can request reading the values of e-variables using JS SDK. In the tests, you can read any value bypassing the access control checks.

​
For euint256

getUint256Value(euint256 input) (uint256);

// example usage
assertEq(getUint256Value(token.balanceOf(alice)), 9 * GWEI);

​
For ebool

getBoolValue(ebool input) (bool);

// example usage
assertEq(getBoolValue(someContract.isActive()), true);
To fully test how one of your user could see its encrypted data, we recommend combining an assertion over the decrypted value with an access control check. 
// example, we check that alice can read her balance
assertTrue(token.balanceOf(alice).isAllowed(alice));
