 ### Testing
 
 We are in the process of migrating our tests to use [Foundry](https://book.getfoundry.sh/). The tests in this folder have already been migrated from [Truffle](../test).

-### Testing
-
-We are in the process of migrating our tests to use [Foundry](https://book.getfoundry.sh/). The tests in this folder have already been migrated from [Truffle](../test).
-
-To run tests with Foundry there's no need to `yarn` or manage any Javascript dependencies. Instead, run
-
-```bash
-forge test
-```
-
-This will run all tests in this folder. To run only a specific file you can use
-
-```bash
-forge test --match-path ./path/to/file.t.sol
-```
-
-To run only a specific contract in a test file, you can use
-
-```bash
-forge test --match-contract CONTRACT_NAME
-```
-
-To run only a specific test, you can use
-
-```bash
-forge test --match-test test_ToMatch
-```
-
-You can specify a verbosity level with the `-v`, `-vv`, `-vvv`, and `-vvvv` flags. The more `v`s you put the more verbose the output will be.
-
-Putting it all together, you might run something like
-
-```bash
-forge test --match-path ./path/to/file.t.sol --match-test test_ToMatch -vvv
-```
-
-You can read more about the `forge test` command [here](https://book.getfoundry.sh/reference/forge/forge-test).
-
-To skip a specific test, you can add `vm.skip(true);` as the first line of the test.
-
-If a test name begins with `testFail` rather than `test`, foundry will expect the test to fail / revert.
-
-Please follow the naming convention `test_NameOfTest` / `testFail_NameOfTest`.
-
-If you're new to Forge / Foundry, we recommend looking through the [Cheatcode Reference](https://book.getfoundry.sh/cheatcodes/) for a list of useful commands that make writing tests easier.
