( #3333=superdoc: print w/replies, xml ) Need Help??
I have inherited a proprietary testing system that uses 200 individual Perl scripts for each test case of an external device (over a serial connection).

Each script uses a custom "Test" module, calls a start routine, does the test in perl using subroutines from it, and then calls an end routine.

On top of that we have a master perl script which calls each perl script (by running it with the system command) in turn.

We are having performance problems. I suspect because it is building a new perl interpreter and reloading the harnass module for each test case.

I want to convert the system over to using a single perl interpreter.

This would involve turning the perl scripts into modules I suspect, loading them somehow at runtime with the master script. (require, use, do, eval? )

Can anyone recommend a strategy as to making this change?

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
