+# ML Test Runner
+
+A test runner for executing Revive differential tests file-by-file with cargo-test-style output.
+
+This is similar to the `retester` binary but designed for ML-based test execution with a focus on:
+- Running tests file-by-file (rather than in bulk)
+- Caching passed tests to skip them in future runs
+- Providing cargo-test-style output for easy integration with ML pipelines
+- Single platform testing (rather than differential testing)
+
+## Features
+
+- **File-by-file execution**: Run tests on individual `.sol` files, corpus files (`.json`), or recursively walk directories
+- **Cached results**: Skip tests that have already passed using `--cached-passed`
+- **Fail fast**: Stop on first failure with `--bail`
+- **Cargo-like output**: Familiar test output format with colored pass/fail indicators
+- **Platform support**: Test against `geth` or `kitchensink` platforms
+
+## Usage
+
+```bash
+# Run a single .sol file (compile-only mode, default)
+./ml-test-runner path/to/test.sol --platform geth
+
+# Run all tests in a corpus file
+./ml-test-runner path/to/corpus.json --platform kitchensink
+
+# Walk a directory recursively for .sol files
+./ml-test-runner path/to/tests/ --platform geth
+
+# Use cached results and bail on first failure
+./ml-test-runner path/to/tests/ --cached-passed ./cache.txt --bail
+
+# Start the platform and execute tests (full mode)
+./ml-test-runner path/to/tests/ --platform geth --start-platform
+
+# Enable verbose logging (info, debug, or trace level)
+RUST_LOG=info ./ml-test-runner path/to/tests/
+RUST_LOG=debug ./ml-test-runner path/to/tests/ --start-platform
+RUST_LOG=trace ./ml-test-runner path/to/tests/ --start-platform
+```
+
+## Arguments
+
+- `<PATH>` - Path to test file (`.sol`), corpus file (`.json`), or folder of `.sol` files
+- `--cached-passed <FILE>` - File to track tests that have already passed
+- `--bail` - Stop after the first file failure
+- `--platform <PLATFORM>` - Platform to test against (`geth`, `kitchensink`, or `zombienet`, default: `geth`)
+- `--start-platform` - Start the platform and execute tests (default: `false`, compile-only mode)
+
+## Output Format
+
+The runner produces cargo-test-style output:
+
+```
+test path/to/test1.sol ... ok
+test path/to/test2.sol ... FAILED
+test path/to/test3.sol ... cached
+
+failures:
+
+---- path/to/test2.sol ----
+Error: ...
+
+test result: FAILED. 1 passed; 1 failed; 1 cached; finished in 2.34s
+```
+
+## Building
+
+```bash
+cargo build --release -p ml-test-runner
+```
+
+The binary will be available at `target/release/ml-test-runner`.
