18 ## Warning: heap big magic in the following tests!!! |
|
|
19 ## The test function builds a private context for each |
|
|
20 ## test, with only the specified values shared between |
|
|
21 ## them. It does this using the following template: |
|
|
22 ## |
|
|
23 ## function [<shared>] = testfn(<shared>) |
|
|
24 ## <test> |
|
|
25 ## |
|
|
26 ## To test inputname, I need a function context invoked |
|
|
27 ## with known parameter names. So define a couple of |
|
|
28 ## shared parameters, et voila!, the test is trivial. |
|
|
29 %!shared hello,worldly |
|
|
30 %!assert(inputname(1),'hello'); |
|
|
31 %!assert(inputname(2),'worldly'); |
