Running

The installation of the prerequisites to run an anchor program is nicely explained in the anchor book.

With the prerequisites out of the way, npm i installs the rest of the dependencies.

Then building and running the tests can be done with anchor test.

To use the tests while working on a frontend run the localnet with anchor localnet.
In another terminal airdrop your wallet some SOL and load the test solana airdrop 1000 <YourPhantomWalletPubKey> && anchor run test.
