How do I create a test file so the following line would work: `LocalFileSystem.getInstance().findFileByPathIfCached(fileName)`
Now I use 
```
project.baseDir
                    .createChildDirectory(null, "src")
                    .createChildDirectory(null, "test")
                    .createChildDirectory(null, "java")
                    .createChildData(null, "JavaTestClass.java")
```
But it works only once :disappointed: Next time I run the test I get: 
```
java.io.IOException: '/private/var/folders/d6/232wh5350xz0fpbbtcz6yddr0000gn/T/unitTest_aame/src' already exists in VFS
```
