Rewriting Pipp tests in PHP

Bernhard on 2008-11-27T20:36:12

Pipp is Parrot's PHP and it has small test suite that lives alongside the code in the Parrot repository. Most of the test scripts are written in Perl 5 using the Parrot::Test modules. So usually I tell Pipp to run some PHP code and check whether the expected result is printed. This works fine but is not very exiting.

More exciting, for some definition of exciting, is to run PHP scripts and emit TAP with a testing lib implemented in PHP. So Pipp this needs

  1. user defined functions with param passing
  2. global for keeping track of the running test count
  3. module loading
Stealing from Rakudo I now got most of that. global is still missing, so currently I pass in the current test number and increment it outside the testing functions.

Over the next days I plan to port a selection of the easier scripts to PHP. Things like TODO, SKIP and regex matching have to wait for later. Takers welcome!

Can TAP library be written in Perl 6? AFAIR, it was one of goals of Parrot: to be possible to use libraries in one language from another.

Right now I know of no example where libraries are written in another high level language. But it is definitly the plan to make this possible.
Implementing the testing library in PHP is of course also driving the development of Pipp. For example I got reminded that Pipp had no support for parameters of user defined functions.

Pheme has used the PIR Test::More for a couple of years. All of Pheme's tests are written in Pheme.
