This adds a basic test harness infrastructure for the mempool package which aims to make writing tests for it much easier. The harness provides functionality for creating and signing transactions as well as a fake chain that provides utxos for use in generating valid transactions and allows an arbitrary chain height to be set. In order to simplify transaction creation, a single signing key and payment address is used throughout and a convenience type for spendable outputs is provided. The harness is initialized with a spendable coinbase output by default and the fake chain height set to the maturity height needed to ensure the provided output is in fact spendable as well as a policy that is suitable for testing. Since tests are in the same package and each harness provides a unique pool and fake chain instance, the tests can safely reach into the pool policy, or any other state, and change it for a given harness without affecting the others. In order to be able to make use of the existing blockchain.Viewpoint type, a Clone method has been to the UtxoEntry type which allows the fake chain instance to keep a single view with the actual available unspent utxos while the mempool ends up fetching a subset of the view with the specifically requested entries cloned. To demo the harness, this also contains a couple of tests which make use of it: - TestSimpleOrphanChain -- Ensures an entire chain of orphans is properly accepted and connects up when the missing parent transaction is added - TestOrphanRejects -- Ensure orphans are actually rejected when the flag on ProcessTransactions is set to reject them |
