| // Fork Testing Example | ||
| // | ||
| // The #test_fork pragma configures this test to run against a snapshot of mainnet state. | ||
| // This allows testing against real deployed contracts and production data without deploying | ||
| // anything to a live network. All mutations happen locally in your test environment. | ||
| // | ||
| // To run this test: flow test cadence/tests/test_incrementfi_swap_on_fork.cdc | ||
| // | ||
| // Learn more about fork testing in the README.md file or at: | ||
