 ## Testing
 
-First, get benchmarks and tests:
+#### octane
+
+Using test runner
 ```sh
-git submodule update --init
+tools/run-tests.py --engine=ESCARGOT_BINARY_PATH octane
 ```
 
-### Benchmarks
-
-Test run for each benchmark (Sunspider, Octane, V8, Chakracore, test262,
-SpiderMonkey, etc.):
+Or directly run octane benchmarks
 ```sh
-tools/run-tests.py --arch=x86_64 spidermonkey test262 v8
+cd test/octane/
+./escargot run.js
 ```
+#### sunspider
+
+Using test runner
+```sh
+tools/run-tests.py --engine=ESCARGOT_BINARY_PATH sunspider-js
+```
+
+#### kraken
+
+download kraken benchmark
+```sh
+git clone https://github.com/mozilla-it/krakenbenchmark.mozilla.org.git
+```
+run kraken benchmark
+```sh
+cd krakenbenchmark.mozilla.org
+./sunspider --shell ESCARGOT_BINARY_PATH --suite kraken-1.1
+```
+results would be stored in `kraken-1.1-results` directory
