+
+## Prerequisites
++ Go 1.19
++ Rust (for version, see [rust-toolchain](./common/libzkp/impl/rust-toolchain))
++ Hardhat / Foundry
++ Docker
+
+To run the tests, it is essential to first pull or build the required Docker images. Execute the following commands in the root directory of the repository to do this:
+
+```bash
+docker pull postgres
+make dev_docker
+```
+
+## Testing Rollup & Coordinator
+
+### For Non-Apple Silicon (M1/M2) Macs
+
+Run the tests using the following commands:
+
+```bash
+go test -v -race -covermode=atomic scroll-tech/rollup/...
+go test -tags="mock_verifier" -v -race -covermode=atomic scroll-tech/coordinator/...
+go test -v -race -covermode=atomic scroll-tech/database/...
+go test -v -race -covermode=atomic scroll-tech/common/...
+```
+
+### For Apple Silicon (M1/M2) Macs
+
+To run tests on Apple Silicon Macs, build and execute the Docker image as outlined below:
+
+#### Build a Docker Image for Testing
+
+Use the following command to build a Docker image:
+
+```bash
+make build_test_docker
+```
+
+This command builds a Docker image named `scroll_test_image` using the Dockerfile found at `./build/dockerfiles/local_test.Dockerfile`.
+
+#### Run Docker Image
+
+After the image is built, run a Docker container from it:
+
+```bash
+make run_test_docker
+```
+
+This command runs a Docker container named `scroll_test_container` from the `scroll_test_image` image. The container uses the host network and has access to the Docker socket and the current directory.
+
+Once the Docker container is running, execute the tests using the following commands:
+
+```bash
+go test -v -race -covermode=atomic scroll-tech/rollup/...
+go test -tags="mock_verifier" -v -race -covermode=atomic scroll-tech/coordinator/...
+go test -v -race -covermode=atomic scroll-tech/database/...
+go test -v -race -covermode=atomic scroll-tech/common/...
+```
+
+## Testing Contracts
+
+You can find the unit tests in [`<REPO_DIR>/contracts/src/test/`](/contracts/src/test/), and integration tests in [`<REPO_DIR>/contracts/integration-test/`](/contracts/integration-test/).
+
+For more details on contracts, see [`/contracts`](/contracts).

-In addition, launching the bridge will launch a separate instance of l2geth, and sets up a communication channel
-between the two, over JSON-RPC sockets.
-
-Something we should pay attention is that all private keys inside sender instance cannot be duplicated.
