ARMmbed#2613 should be merged first 
Using test_api, I found that the test names were dependent on where mbed-os (if that is the root) is stored on disk if you provide anything other than '.' as the root directory. 
This would change names like: 
```
repos-mbed-os-example-blinky-mbed-os-features-storage-feature_storage-tests-cfstore-example3
```
to
```
features-storage-feature_storage-tests-cfstore-example3
