Use Mox by default for local integration tests How to run without Mox is in the root `README.md`. Run all combinations of Variant and Transport on CircleCI to ensure that Mox matches HTTP behavior, so Mox can be used for fast local testing: * Geth, HTTP * Geth, Mox * Parity, HTTP * Parity, Mox Using Mox locally also lessens load on Sokol and the Infura API key the tests use for Geth under the assumption that we do far more local testing than CI testing. May help with #340, but does not fix the root cause, which is now known as `Sequence` not chunking ranges correctly on retry. 6 years ago			`Mox.defmock(EthereumJSONRPC.Mox, for: EthereumJSONRPC.Transport)`
Don't track retry counts All implemented of BufferedTask ignore the number and not tracking it saves memory and simplifies BufferedTask itself. 6 years ago			`Mox.defmock(Indexer.BufferedTaskTest.RetryableTask, for: Indexer.BufferedTask)`
