+
+### 2.2 运行所有用例
+
+```
+python3 test262/run_test262.py
+```
+
+### 2.3 运行 `es51` 相关测试用例
+
+```python
+python3 test262/run_test262.py --es51
+```
+
+执行完成后，在目录' test262/data '下创建一个名为' test_es51 '的目录，该目录用于存储所有' es51 '案例。
+
+### 2.4运行' es2015 '相关的测试用例
+#### 2.4.1只包含ES2015的用例
+```python
+python3 test262/run_test262.py --es2015 only
+```
+#### 2.4.2包含ES5和ES2015的所有用例
+```python
+python3 test262/run_test262.py --es2015 all
+```
+
+### 2.5运行单个测试用例
+
+```python
+python3 test262/run_test262.py --file test262/data/test_es5/language/statements/break/12.8-1.js
+```
+
+### 2.6运行指定目录下的所有测试用例
+
+```python
+python3 test262/run_test262.py --dir test262/data/test_es5/language/statements
+```
+
+### 2.7使用其他引擎运行单个测试用例。以d8为例
+
+```python
+ python3 test262/run_test262.py --engine="/home/share/v8-code/v8/out.gn/x64.release/d8" --file test262/data/test_es5/language/statements/break/12.8-1.js
+```
+### 2.8 使用‘babel’转换运行单个测试用例
+```
+python3 test262/run_test262.py  --babel --file test262/data/test_es5/language/statements/break/12.8-1.js
+```
+
+### 2.9 得到测试结果
+

+
+```shell
