// Flow:
// init indexer
// init first keypair
// init crank
// vec of public Merkle tree NF queue pairs
// vec of public address Mt and queue pairs
// for i in rounds
//   randomly add new keypair
// for every keypair randomly select whether it does an action

// Architecture:
// - bundle trees, indexer etc in a E2ETestEnv struct
// - methods:
// 	// bundles all general actions
//   - activate general actions
//   // bundles all keypair actions
//   - activate keypair actions
// 	// calls general and keypair actions
//   - execute round
//   // every action takes a probability as input
//   // if you want to execute the action on purpose pass 1
//   - method for every action
//  - add action activation config with default configs
//    - all enabled
//    - only spl, only sol, etc
//  Forester struct
//  - payer keypair, authority keypair
//  -methods
//   - empty nullifier queue
//   - empty address queue
//   - rollover Merkle tree
//   - rollover address Merkle tree

// keypair actions:
// safeguard every action in case of no balance
// 1. compress sol
// 2. decompress sol
// 2. transfer sol
// 3. compress spl
// 4. decompress spl
// 5. mint spl
// 6. transfer spl

// general actions:
// add keypair
// create new state Mt
// create new address Mt

// extension:
// keypair actions:
// - create pda
// - escrow tokens
// - delegate, revoke, delegated transaction

// general actions:
// - create new program owned state Merkle tree and queue
// - create new program owned address Merkle tree and queue

// minimal start
// struct with env and test-indexer
// only spl transactions

// second pr
// refactor sol tests to functions that can be reused

// TODO: implement traits for context object and indexer that we can implement with an rpc as well
// context trait: send_transaction -> return transaction result, get_account_info -> return account info
// indexer trait: get_compressed_accounts_by_owner -> return compressed accounts,
// refactor all tests to work with that so that we can run all tests with a test validator and concurrency
