This directory contains two test suites. The Logtalk test suite includes unit
tests for built-in entities, predicates, control constructs, directives, and
methods. Besides this set of unit tests, there are also unit tests defined
for most libraries, developer tools, examples, contributions, and ports.

The Prolog test suite includes conformance tests for both official and de
facto standards. It can be used to highlight differences between backend
Prolog compilers when porting and testing Logtalk applications. See the
`prolog/NOTES.md` file for details about the these tests and how to run
them.

You can automate running all these tests by calling the `logtalk_tester`
shell script from the command-line (see the `scripts/NOTES.md` file for
details on how to use this script with POSIX and Windows operating-systems).
Type `man logtalk_tester` or `logtalk_tester -h` for usage details, including
how to select the backend Prolog compiler.

To run all the provided unit tests with e.g. SWI-Prolog as the backend
compiler, open a terminal and type:

	$ cd $LOGTALKUSER
	$ logtalk_tester -p swi
	...

You can also run the test sets individually:

	$ cd $LOGTALKUSER/tests/logtalk
	$ logtalk_tester -p swi
	...

	$ cd $LOGTALKUSER/tests/prolog
	$ logtalk_tester -p swi
	...

	$ cd $LOGTALKUSER/tools
	$ logtalk_tester -p swi
	...

	$ cd $LOGTALKUSER/examples
	$ logtalk_tester -p swi
	...

	$ cd $LOGTALKUSER/contributions
	$ logtalk_tester -p swi
	...
