You can use console.log with vm.toString() to convert bytes32 to a readable string and log it alongside a label:

import "forge-std/Test.sol";
import "forge-std/console.sol";

bytes32 myValue = 0xabc123...;

// Option 1 — label + bytes32 as string
console.log("myValue:", vm.toString(myValue));

// Option 2 — multiple values with labels
bytes32 hashA = keccak256("foo");
bytes32 hashB = keccak256("bar");

console.log("hashA:", vm.toString(hashA));
console.log("hashB:", vm.toString(hashB));

vm.toString(bytes32) converts the raw bytes into a human-readable hex string so you can identify which is which in test output.

Alternative — use console.logBytes32():

console.log("hashA:");
console.logBytes32(hashA);

But vm.toString() is cleaner since it lets you put the label and value on the same line.
