In both encoding and contracts: - Make sure that the tests names/encoder match what is happening (we had test_split_... that was only a single swap). - Made modules inside the encodings tests - In swap_encoders: there is one module per protocol - In strategy_encoders: there is one module per strategy and an extra protocol_integration module. Inside the sequential module there is another module called chained_swaps - In contracts, each strategy has its own file. Integration tests per strategy should also be here. Renamed TychoRouterIntegration to TychoRouterProtocolIntegration. Only protocol integration tests should be in this file --- don't change below this line --- ENG-4327 Took 1 hour 13 minutes
