lib/testing.cf
The testing.cf
library provides bundles for working testing frameworks like
TAP and jUnit.
These bodies are included in the stdlib by default.

testing_ok_if
Prototype: testing_ok_if(classname, message, error, trace, format)
Description: Report outcome for test on classname
in format format
with optional error
and trace
Arguments:
classname
: The class namemessage
: The test messageerror
: The error to report, if the class is not definedtrace
: The error trace detail to report, if the class is not definedformat
: TAP (immediate output) or jUnit or anything else for delayed TAP
See also: testing_junit_report
, testing_tap_report
, testing_ok
, testing_todo
, and testing_skip
Implementation:
bundle agent testing_ok_if(classname, message, error, trace, format)
{
vars:
"next_testing_$(classname)" int => length(classesmatching("testing_.*", "testing_(passed|failed|skipped|todo)"));
"next_testing_$(classname)_failed" int => length(classesmatching("testing_.*", "testing_(passed|failed|skipped|todo)"));
classes:
"tap" expression => strcmp('tap', string_downcase($(format)));
"testing_$(classname)" expression => $(classname), scope => "namespace", meta => { "testing_passed", "error=$(error)", "trace=$(trace)", "message=$(message)" };
"testing_$(classname)_failed" not => $(classname), scope => "namespace", meta => { "testing_failed", "error=$(error)", "trace=$(trace)", "message=$(message)" };
reports:
inform_mode::
"$(this.bundle): adding testing report for class $(classname) at position $(next_testing_$(classname))";
"tap.testing_$(classname)"::
"$(const.n)ok $(message)";
"tap.testing_$(classname)_failed"::
"$(const.n)not ok $(message)";
}
testing_ok
Prototype: testing_ok(classname, message, format)
Description: Report expected success in format format
for classname
and its test
Arguments:
classname
: The class namemessage
: The test messageformat
: TAP (immediate output) or jUnit or anything else for delayed TAP
This bundle calls testing_ok_if
expecting classname
to be defined and thus the
test to be a success; the error and trace reflect that.

, testing_tap_report
, testing_ok_if
, testing_todo
, and testing_skip
Implementation:
bundle agent testing_ok(classname, message, format)

methods:
"" usebundle => testing_ok_if($(classname), $(message), "unexpected error for $(classname)", "no error trace available", $(format));
}
testing_skip
Prototype: testing_skip(classname, message, format)
Description: Report skipped classname
in format format
Arguments:
classname
: The class namemessage
: The test messageformat
: TAP (immediate output) or jUnit or anything else for delayed TAP
This bundle reports that classname
was skipped regardless of whether it's
defined.

, testing_tap_report
, testing_ok_if
, testing_todo

Implementation:

"$(const.n)ok # SKIP $(message)";
}
testing_todo
Prototype: testing_todo(classname, message, format)
Description: Report TODO classname
in format format
Arguments:
classname
: The class namemessage
: The test messageformat
: TAP (immediate output) or jUnit or anything else for delayed TAP
This bundle reports that classname
was skipped regardless of whether it's
defined.

classes:
"tap" expression => strcmp('tap', string_downcase($(format)));

testing_tap_report
Prototype: testing_tap_report(outfile)
Description: Report all test messages in TAP format to outfile
Arguments:
outfile
: A text file with the final TAP report or empty `` for STDOUT report

Description: Report all test knowledge in jUnit format to outfile
Arguments:
format
: The output format, eitherjUnit
orTAP
(case is ignored)outfile
: A file with the final report or empty for STDOUT
Note that jUnit output to STDOUT will most likely be truncated due to the 4K limitation on string lengths.

testing_usage_example
Prototype: testing_usage_example
Description: Simple demo of testing_junit_report and testing_tap_report testing.cf usage
You can run it like this: cf-agent -K ./testing.cf -b testing_usage_example
Or for extra debugging, you can run it like this: cf-agent -KI ./testing.cf -b testing_usage_example
You can either use tap
as the format
parameter for any testing bundle, in
which case you get immediate TAP output, OR you can use anything else, in
which case you can still get TAP output but at the end.
So your use cases are:
- format=jUnit, then testing_junit_report(''): all jUnit to STDOUT, output at end
- format=TAP, then testing_tap_report(''): all TAP to STDOUT, immediate output
- format=delayed_TAP, then testing_tap_report(MYFILE): all TAP to MYFILE, output at end
- format=jUnit, then testing_jUnit_report(MYFILE): all jUnit to MYFILE, output at end
