-This repo is using [vitest](https://vitest.dev) as the test runner. Most of the tests are written as [snapshot tests](https://vitest.dev/guide/snapshot.html). The test will run and save the result as snapshot in a `.snap` file, and next time when the test runs again, it will compare the result with the snapshot. This eliminates the need to write assertions and make the test more readable.

-It is recommended use `yarn update-env` to update the `.env` file with latest block number before running the tests. This ensures tests are always running against the same blocks so that block data can be cached and reused to speed up test running time. Once you have a working test, update the blocks number again and rerun the tests to ensure the tests are block number indpendent. Use `redact` and event filters to make the snapshot be consistent regardless the block number.

 ### Debugging Tips
 
 - Move the failed test to [playground.test.ts](./tests/xcm-transfer/playground.test.ts) to only run the failed test.
-- Use `yarn vitest` instead of `yarn test` to display logs.
-- Add `-u` to automatically update snapshots and use git diff tool to compare the changes.
+- Add `--update-snapshots` to automatically update snapshots and use git diff tool to compare the changes.
 - For failed CI tests, check the block numbers from the `update-env` steps in the logs to local `.env` file to be able to run the tests with the same block height.
 - Remove the system events filter to see all the events in snapshots.
 	- e.g. Replace `checkSystemEvents(toChain, 'parachainSystem', 'dmpQueue')` to `checkSystemEvents(toChain)`
