Run the following commands to create a test case directory and upload the test case package to the directory:
```
mkdir -p /path/to/SWAN/swan-testcse
cd /path/to/SWAN/swan-testcse

```
Run the following commands to go to the directory and create a soft link:
```
cd refract
ln -s /path/to/SWAN/swan4131/swan.exe ./
```
Run the following commands to run the case:
