• [x] eth_call - non existing contract
• [x] eth_call - existing contract view function and existing from
• [x] eth_call - existing contract tx and existing from
• [x] eth_call - existing contract tx, existing from and positive value
• [x] eth_call - existing contract view function and non-existing from
• [x] eth_call - existing contract tx and non-existing from
• [x] eth_call - existing contract tx, non-existing from and positive value
• [x] eth_estimateGas - non existing contract
• [x] eth_estimateGas - existing contract view function and existing from
• [x] eth_estimateGas - existing contract tx and existing from
• [x] eth_estimateGas - existing contract tx, existing from and positive value
• [x] eth_estimateGas - existing contract view function and non-existing from
• [x] eth_estimateGas - existing contract tx and non-existing from
• [x] eth_estimateGas - existing contract tx, non-existing from and positive value
• [x] eth_getLogs - non-existing contract
• [x] eth_getLogs - existing contract

@Nana-EC adding 3 as points because the number of tests is pretty big but with no architecture changes. Thanks to these tests, we found a bug in the mirror node.
