+# Fuzz Test for GreptimeDB
+
+## Setup
+1. Install the [fuzz](https://rust-fuzz.github.io/book/cargo-fuzz/setup.html) cli first.
+```bash
+cargo install cargo-fuzz
+```
+
+2. Start GreptimeDB
+3. Copy the `.env.example`, which is at project root, to `.env` and change the values on need.
+
+## Run
+1. List all fuzz targets
+```bash
+cargo fuzz list --fuzz-dir tests-fuzz
+```
+
+2. Run a fuzz target.
+```bash
+cargo fuzz run fuzz_create_table --fuzz-dir tests-fuzz
+```
+
+## Crash Reproduction
+If you want to reproduce a crash, you first need to obtain the Base64 encoded code, which usually appears at the end of a crash report, and store it in a file.
+
+Alternatively, if you already have the crash file, you can skip this step.
+
+```bash
+echo "Base64" > .crash
+```
+Print the `std::fmt::Debug` output for an input.
+
+```bash
+cargo fuzz fmt fuzz_target .crash --fuzz-dir tests-fuzz  
+```
+Rerun the fuzz test with the input.
+
+```bash
+cargo fuzz run fuzz_target .crash --fuzz-dir tests-fuzz
+```
+For more details, visit [cargo fuzz](https://rust-fuzz.github.io/book/cargo-fuzz/tutorial.html) or run the command `cargo fuzz --help`.
