I am trying to make a unit-testing framework for J, in the lines of
the other standard star-unit frameworks, for example, like JUnit
http://en.wikipedia.org/wiki/JUnit
However, I found the facilities for reflection and exception handling
in J is wanting compared to other languages like Java.
---------
sum=: +
mul=: *
should_eq=: dyad :0
:
text=. ''
if. -.x-:y do.
text=. x ([,' -...@-: ',])&": y
end.
text assert x-:y
)
test_sum=: monad : 0
10 should_eq sum/ 1 2 3 4
10 should_eq sum/ 1 2 3
)
test_mul=: monad : 0
24 should_eq mul/ 1 2 3 4
6 should_eq mul/ 1 2 3 4
)
all_test=: monad : 0
test_sum''
test_mul''
)
all_test''
---------
First limitation: I want to get the line number(in the script file
along with the file name) when there is a failure. How do I get this?
(13!:13 was a possible path but the line number there isn't the LN
from the top of the file)
Second limitation: each test case should run independently from each
other. That means the failure in test_sum shouldn't stop running
test_mul. What is an easy and flexible way? (maybe making a gerund
array of test_sum and test_mul, and running through the gerund array
to execute each verb inside try, catch statement -- handling the
failure appropriately afterwards)
Gathering all the verbs that start with "test_" wouldn't be that hard.
(reflection)
