All you need is two functions. Testing should be easy. The Test Anything Protocol makes it easy to do testing with just two just two functions.

1. software Testing
Presented by Lambert Lum
All you need is two functions

2. Test Anything Protocol
Test Anything Protcol (TAP)
Lets you do all your testing with two functions

3. Supported Languages
Perl
Python
PHP
Ruby
JavaScript
C
C++
Java
Forth

4. Perl
Our presentation will use Perl

5. How many tests
use Test::More tests => 1;

6. done_testing()
# Can't be bothered to specify number of tests
done_testing();
# bottom of test script

7. ok()
use Test::More tests => 1;
my $bool = 1;
ok ($bool, "boolean test");

8. is()
use Test::More tests => 1;
my $got = 5 * 2;
my $expected = 10;
is ($got, $expected, "got equals expected");

9. We’re done
All you need is ok() and is()
Let’s all go home.

10. What? You’re Still here?
Seriously, everything can be done with ok() and is()
It’s that simple

11. Wait! There’s more
The following slides have optional, but nice features

12. prove
# run all the test scripts in the t directory
$ prove t

13. prove
$ prove t
t/done_testing.t .. ok
t/is.t ............ ok
t/ok.t ............ ok
t/ok_is.t ......... ok
All tests successful.
Files=4, Tests=5, 0 wallclock secs ( 0.04 usr
0.00 sys + 0.20 cusr 0.01 csys = 0.25 CPU)
Result: PASS

14. prove
# run test scripts in parallel
$ prove --jobs 9 t

15. prove
# parallelize optimally
$ prove --jobs 9 --state=save,slow t

16. Test::Harness
The prove command is part of Test::Harness

17. eq_or_diff
For comparing deeply nested data structures.
Will produce side-by-side diffs on fail.

18. eq_or_diff
use Test::More tests => 1;
use Test::Differences qw(eq_or_diff);
eq_or_diff (
$hash,
{
name => 'Jagermech',
armament => {
RA => ['Autocannon 2', 'LRM 15'],
},
},
"comparing data structures",
);

19. Test::Exception
dies_ok ( sub { die "now dieing"; }, "die");
lives_ok ( sub { }, "no die");

20. Test::Fatal
Simpler alternative to Test::Exception
Lambert has no practice in this

21. Test::BDD::Cucumber
Gives an English-like way for project managers to write test
Lambert hasn’t used it

22. Test::Pod
For testing your POD documentation
Lambert has no practice in this

23. Supplementary info
The following slides are not part of Test Anything Protocol
They are still useful, though

24. Devel::Cover
Coverage testing
Lambert has no practice in this

25. Devel::NYTProf
Profiling on per-line and per-subroutine
Produces HTML web pages
