I'd prefer keeping this as is, as the parameters are also logged in the `test*Parameter` when the thread is actually executed. This is just to make sure that the parameters are added to the list of threads, which would be easier in this format, as they are set in this format in the list above. 

log: 

Option added to all lowercase tests [properties, properties\[.*\|main|\\d{4}-\\d{2}-\\d{2}.*\]:, properties:]

code: 
```java 
new String[]{"properties",
             EXPECTED_PROP_REGEX,
             "properties:"},
