### 2.2 Run all the test cases

```
python3 test262/run_test262.py
```

### 2.3 Run `es51` related test cases

```python
python3 test262/run_test262.py --es51
```

After the execution finished, a directory named `test_es51` is created under directory `test262/data` , which is used to store all `es51` cases.

### 2.4 Run `es2015` related test cases
#### 2.4.1 only include use cases for ES2015
```python
python3 test262/run_test262.py --es2015 only
```
#### 2.4.2  Contains all use cases for ES5 and ES2015
```python
python3 test262/run_test262.py --es2015 all
```

### 2.5 Run single test case

```python
python3 test262/run_test262.py --file test262/data/test_es5/language/statements/break/12.8-1.js
```

### 2.6 Run all the test cases under specified directory

```python
python3 test262/run_test262.py --dir test262/data/test_es5/language/statements
```

### 2.7 Run single test case with other engines. Take d8 as an example

```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 Run single test case with `babel` conversion
```
python3 test262/run_test262.py  --babel --file test262/data/test_es5/language/statements/break/12.8-1.js
```

### 2.9 Get test result

take the following code as an example:

```shell
zgy@lfgphicprd23154:/home/share/OpenHarmony2.0_20210604/ark/ts2abc$ python3 -B test262/run_test262.py --file test262/data/test_es51/language/statements/break/12.8-1.js

* `default` indicates `non-strict` mode; `strict mode` indicates the strict mode.

* After the execution finished, the following files are generated under directory `out/test262/` (you can specified it in `test262/config.py`):

```
-rw-rw-r-- 1 zgy zgy 7583 Nov 21 18:18 12.8-1-default.abc
-rw-rw-r-- 1 zgy zgy 415 Nov 21 18:18 12.8-1.js.panda.default.err

-rw-rw-r-- 1 zgy zgy 7601 Nov 21 18:18 12.8-1-strict.abc
```

`.abc` indicates the generated binary `abc` file.

`.err` indicates that an error occurred during the test.

`.fail/.pass` is the file saved after `js` file has been preprocessed.

The `result.txt` file is generated under directory `out/test262` to save statistics after the test finished.
