+# Getting started with a new system test
+
+## Overview
+
+The systemtests suite is an end-to-end test suite that runs the evmd process and sends RPC requests from separate Ethereum/Cosmos clients. The systemtests for cosmos/evm use the `cosmossdk.io/systemtests` package by default. For more details, please refer to https://github.com/cosmos/cosmos-sdk/tree/main/tests/systemtests.
+
+## Preparation
+
+Build a new binary from current branch and copy it to the `tests/systemtests/binaries` folder by running system tests.
+
+```shell
+make test-system
+```
+
+Or via manual steps
+
+```shell
+make build
+mkdir -= ./tests/systemtests/binaries
+cp ./build/evmd ./tests/systemtests/binaries
+cp ./build/evmd ./tests/systemtests/binaries/v0.4
+```
+
+## Run Individual test
+
+### Run test cases for txs ordering
+
+```shell
+go test -p 1 -parallel 1 -mod=readonly -tags='system_test' -v ./... \
+--run TestTxsOrdering --verbose --binary evmd --block-time 5s --chain-id local-4221
+```
+
+### Run test cases for txs replacement
+
+```shell
+go test -p 1 -parallel 1 -mod=readonly -tags='system_test' -v ./... \
+--run TestTxsReplacement --verbose --binary evmd --block-time 5s --chain-id local-4221
+```
+
+### Run test exceptions
+
+```shell
+go test -p 1 -parallel 1 -mod=readonly -tags='system_test' -v ./... \
+--run TestExceptions --verbose --binary evmd --block-time 5s --chain-id local-4221
+```
+
+## Run Entire test
+
+```shell
+make test
+```
