OpenVMS Pascal - testing tools?

Post by garyrevell » Thu Nov 19, 2020 10:56 am

Hi,

Anyone know of any unit test tools for OpenVMS Pascal?

I'm looking for something a la Java JUNIT or Python Pytest etc. I'd like to write a suite of tests for our application and using a tool would be handy. Perhaps DTM has something I could use?

Thanks

Gary

I am not aware of anything.

Delphi DUnit2 and Lazarus FPTest will not work with VMS Pascal.

I think it will have to be DIY.

But it is not so hard to do.

I started and got:

$ typ testdemo.pas
[inherit('demo', 'vpunit')]
program testdemo(input, output);

procedure test_add2;

var
a, b, c : integer;

begin
a := 123;
b := 456;
c := add2(a, b);
vpunit_check_integer_equals(579, c, 'add2(123, 456)');
end;

procedure test_sub2;

var
a, b, c : integer;

begin
a := 579;
b := 123;
c := sub2(a, b);
vpunit_check_integer_equals(456, c, 'sub2(579, 123)');
end;

procedure test_mul2;

var
a, b, c : integer;

begin
a := 11;
b := 12;
c := mul2(a, b);
vpunit_check_integer_equals(131, c, 'mul2(11, 12)');
end;

procedure test_div2;

var
a, b, c : integer;

begin
a := 50;
b := 3;
c := div2(a, b);
vpunit_check_integer_equals(16, c, 'div2(50, 3)');
end;

procedure test_alwaystrue;

var
b : boolean;

begin
b := alwaystrue;
vpunit_check_true(b, 'alwaystrue');
end;

procedure test_dup;

var
s, s2 : varstr;

begin
s := 'ABC';
s2 := dup(s);
vpunit_check_fixstring_equals('ABCABC', s, 'dup(''ABC'')');
end;

begin
vpunit_test(test_add2);
vpunit_test(test_sub2);
vpunit_test(test_mul2);
vpunit_test(test_div2);
vpunit_stats;
end.

$ r testdemo
Failure: expected 131 actual 23 for mul2(11, 12)
4 test run: 1 failed

If there is interest then I could zip this stuff up and make it available for download.

But it is pretty trivial.

DTM would work if you have a license for it or DECset. Have a look at the latest DTM Guide https://vmssoftware.com/docs/VSI_DTM_GD.PDF

Thanks very much for this, unfortunately I fell at the first hurdle when trying it :
$ pas testdemo

[inherit('demo', 'vpunit')]
..........^
%PASCAL-F-FNF, file not found
at line number 1 in file MYROOT:[dev.pascal]testdemo.pas;1

%PASCAL-F-SRCERRORS, Source errors inhibit continued compilation - correct and recompile
%PASCAL-F-ENDDIAGS, PASCAL completed with 2 diagnostics
I'm a newbie to Pascal so not sure where the demo & vpunit files are/should be.

But I do like the look of the vpunit_ procedures but didn't see any documentation about them.

Thanks!

Thanks, we've got DTM and will have a more serious look at the documentation.

The vpunit stuff is something I wrote for this.

Module demo is the module I want to unit test.

Module vpunit is the vpunit_ routines.

So right now it only exist on my system.

I can ZIP it up and make it available for download if anybody want.

Thanks Arne, that'd be great! Look forward to getting hold of the sources, will you post a link or will they be attached to a post?

I was going to try writing my own test harness using ASSERT and catching thrown exceptions etc and then realised VMS Pascal doesn't have try/except blocks.

Best regards

And it is not really much.

But if you have some suggestions for improvement please tell me.

Thanks a lot Arne, I'll give it a go later today. It's certainly a good approach and perhaps I can build on it too.

Best regards
