How to find number of tests in J48 ruleset

Can someone please answer follow question?
Open weather.nominal in the WEKA Explorer, run J48 (with default 
parameters),generate rules by reading them off the resulting tree. How many 
does test the ruleset has?
I have clicked on visualize tree and able to find the number of rules since 
it is same number of leaves which is 5. By the way I know the number of 
tests is 9. But don't know how
the count is 9 and what are they? Can someone explain this thanks.

Below is the weather.nominal data

\@relation weather.symbolic

\@attribute outlook {sunny, overcast, rainy}
\@attribute temperature {hot, mild, cool}
\@attribute humidity {high, normal}
\@attribute windy {TRUE, FALSE}
\@attribute play {yes, no}

\ @data sunny,hot,high,FALSE,no sunny,hot,high,TRUE,no overcast,hot,high,FALSE,yes rainy,mild,high,FALSE,yes rainy,cool,normal,FALSE,yes rainy,cool,normal,TRUE,no overcast,cool,normal,TRUE,yes sunny,mild,high,FALSE,no sunny,cool,normal,FALSE,yes rainy,mild,normal,FALSE,yes sunny,mild,normal,TRUE,yes overcast,mild,high,TRUE,yes overcast,hot,normal,FALSE,yes rainy,mild,high,TRUE,no
