-.Sh NAME
-.Nm tap
-.Nd write tests that implement the Test Anything Protocol
-.Sh SYNOPSIS
-.In tap.h
-.Sh DESCRIPTION
-The
-.Nm
-library provides functions for writing test scripts that produce output
-consistent with the Test Anything Protocol. A test harness that parses
-this protocol can run these tests and produce useful reports indicating
-their success or failure.
-.Ss PRINTF STRINGS
-In the descriptions that follow, for any function that takes as the
-last two parameters
-.Dq Fa char * , Fa ...
-it can be assumed that the
-.Fa char *
-is a
-.Fn printf
--like format string, and the optional arguments are values to be placed
-in that string.
-.Ss TEST PLANS
-.Bl -tag -width indent
-.It Xo
-.Ft void
-.Fn plan_tests "unsigned int"
-.Xc
-.It Xo
-.Ft void
-.Fn plan_no_plan "void"
-.Xc
-.It Xo
-.Ft void
-.Fn plan_skip_all "char *" "..."
-.Xc
-.El
-.Pp
-You must first specify a test plan. This indicates how many tests you
-intend to run, and allows the test harness to notice if any tests were
-missed, or if the test program exited prematurely.
-.Pp
-To do this, use
-.Fn plan_tests .
-The function will cause your program to exit prematurely if you specify
-0 tests.
-.Pp
-In some situations you may not know how many tests you will be running, or
-you are developing your test program, and do not want to update the
-.Fn plan_tests
-parameter every time you make a change. For those situations use
-.Fn plan_no_plan .
-It indicates to the test harness that an indeterminate number
-of tests will be run.
-.Pp
-Both
-.Fn plan_tests
-and
-.Fn plan_no_plan
-will cause your test program to exit prematurely with a diagnostic
-message if they are called more than once.
-.Pp
-If your test program detects at run time that some required functionality
-is missing (for example, it relies on a database connection which is not
-present, or a particular configuration option that has not been included
-in the running kernel) use
-.Fn plan_skip_all ,
-passing as parameters a string to display indicating the reason for skipping
-the tests.
-.Ss SIMPLE TESTS
-.Bl -tag -width indent
-.It Xo
-.Ft unsigned int
-.Fn ok "expression" "char *" "..."
-.Xc
-.It Xo
-.Ft unsigned int

-.Xc
-.It Xo
-.Ft unsigned int
-.Fn pass "char *" "..."
-.Xc
-.It Xo
-.Ft unsigned int
-.Fn fail "char *" "..."
-.Xc
-.El
-.Pp
-Tests are implemented as expressions checked by calls to the
-.Fn ok
-and
-.Fn ok1
-macros. In both cases
-.Fa expression
-should evaluate to true if the test succeeded.
-.Pp
-.Fn ok
-allows you to specify a name, or comment, describing the test which will
-be included in the output.
-.Fn ok1
-is for those times when the expression to be tested is self
-explanatory and does not need an associated comment. In those cases
-the test expression becomes the comment.
-.Pp
-These four calls are equivalent:
-.Bd -literal -offset indent
-int i = 5;
-
-ok(i == 5, "i equals 5"); /* Overly verbose */
-ok(i == 5, "i equals %d", i); /* Just to demonstrate printf-like
- behaviour of the test name */
-ok(i == 5, "i == 5"); /* Needless repetition */
-ok1(i == 5); /* Just right */
-.Ed
-.Pp
-It is good practice to ensure that the test name describes the meaning
-behind the test rather than what you are testing. Viz
-.Bd -literal -offset indent
-ok(db != NULL, "db is not NULL"); /* Not bad, but */
-ok(db != NULL, "Database conn. succeeded"); /* this is better */
-.Ed
-.Pp
-.Fn ok
-and
-.Fn ok1
-return 1 if the expression evaluated to true, and 0 if it evaluated to
-false. This lets you chain calls from
-.Fn ok
-to
-.Fn diag
-to only produce diagnostic output if the test failed. For example, this
-code will include diagnostic information about why the database connection
-failed, but only if the test failed.
-.Bd -literal -offset indent
-if (!ok(db != NULL, "Database conn. succeeded")) {
- diag("Database error code: %d", dberrno);
-}
-.Ed
-.Pp
-You also have
-.Fn pass
-and
-.Fn fail .
-From the Test::More documentation:
-.Bd -literal -offset indent
-Sometimes you just want to say that the tests have passed.
-Usually the case is you've got some complicated condition
-that is difficult to wedge into an ok(). In this case,
-you can simply use pass() (to declare the test ok) or fail
-(for not ok).
-
-Use these very, very, very sparingly.
-.Ed
-.Pp
-These are synonyms for ok(1, ...) and ok(0, ...).
-.Ss SKIPPING TESTS
-.Bl -tag -width indent
-.It Xo
-.Ft void
-.Fn skip "unsigned int" "char *" "..."
-.Xc
-.It Xo
-.Fn skip_if "expression" "unsigned int" "char *" "..."
-.Xc
-.El
-.Pp
-Sets of tests can be skipped. Ordinarily you would do this because
-the test can't be run in this particular testing environment.
-.Pp
-For example, suppose some tests should be run as root. If the test is
-not being run as root then the tests should be skipped. In this
-implementation, skipped tests are flagged as being ok, with a special
-message indicating that they were skipped. It is your responsibility
-to ensure that the number of tests skipped (the first parameter to
-.Fn skip )
-is correct for the number of tests to skip.
-.Pp
-One way of implementing this is with a
-.Dq do { } while(0);
-loop, or an
-.Dq if( ) { } else { }
-construct, to ensure that there are no additional side effects from the
-skipped tests.
-.Bd -literal -offset indent
-if(getuid() != 0) {
- skip(1, "because test only works as root");
-} else {
- ok(do_something_as_root() == 0, "Did something as root");
-}
-.Ed
-.Pp
-A convenient macro is provided to assist with this. The previous example could
-be re-written as follows.
-.Bd -literal -offset indent
-skip_if(getuid() != 0, 1, "because test only works as root") {
- ok(do_something_as_root() == 0, "Did something as root");
-}
-.Ed
-.Ss MARKING TESTS AS Dq TODO
-.Bl -tag -width indent
-.It Xo
-.Ft void
-.Fn todo_start "char *" "..."
-.Xc
-.It Xo
-.Ft void
-.Fn todo_end "void"
-.Xc
-.El
-.Pp
-Sets of tests can be flagged as being
-.Dq TODO .
-These are tests that you expect to fail, probably because you haven't
-fixed a bug, or finished a new feature yet. These tests will still be
-run, but with additional output that indicates that they are expected
-to fail. Should a test start to succeed unexpectedly, tools like
-.Xr prove 1
-will indicate this, and you can move the test out of the todo
-block. This is much more useful than simply commenting out (or
-.Dq #ifdef 0 ... #endif )
-the tests.
-.Bd -literal -offset indent
-todo_start("dwim() not returning true yet");
-
-ok(dwim(), "Did what the user wanted");
-
-todo_end();
-.Ed
-.Pp
-Should
-.Fn dwim
-ever start succeeding you will know about it as soon as you run the
-tests. Note that
-.Em unlike
-the
-.Fn skip_*
-family, additional code between
-.Fn todo_start
-and
-.Fn todo_end
-.Em is
-executed.
-.Ss SKIP vs. TODO
-From the Test::More documentation;
-.Bd -literal -offset indent
-If it's something the user might not be able to do, use SKIP.
-This includes optional modules that aren't installed, running
-under an OS that doesn't have some feature (like fork() or
-symlinks), or maybe you need an Internet connection and one
-isn't available.
-
-If it's something the programmer hasn't done yet, use TODO.
-This is for any code you haven't written yet, or bugs you have
-yet to fix, but want to put tests in your testing script
-(always a good idea).
-.Ed
-.Ss DIAGNOSTIC OUTPUT
-.Bl -tag -width indent
-.It Xo
-.Fr void
-.Fn diag "char *" "..."
-.Xc
-.El
-.Pp
-If your tests need to produce diagnostic output, use
-.Fn diag .
-It ensures that the output will not be considered by the TAP test harness.
-.Fn diag
-adds the necessary trailing
-.Dq \en
-for you.
-.Bd -literal -offset indent
-diag("Expected return code 0, got return code %d", rcode);
-.Ed
-.Ss EXIT STATUS
-.Bl -tag -width indent
-.It Xo
-.Fr int
-.Fn exit_status void
-.Xc
-.El
-.Pp
-For maximum compatability your test program should return a particular
-exit code. This is calculated by
-.Fn exit_status
-so it is sufficient to always return from
-.Fn main
-with either
-.Dq return exit_status();
-or
-.Dq exit(exit_status());
-as appropriate.
-.Sh EXAMPLES
-The
-.Pa tests
-directory in the source distribution contains numerous tests of
-.Nm
-functionality, written using
-.Nm .
-Examine them for examples of how to construct test suites.
-.Sh COMPATABILITY
-.Nm
-strives to be compatible with the Perl Test::More and Test::Harness
-modules. The test suite verifies that
-.Nm
-is bug-for-bug compatible with their behaviour. This is why some
-functions which would more naturally return nothing return constant
-values.
-.Pp
-If the
-.Lb libpthread
-is found at compile time,
-.Nm
-.Em should
-be thread safe. Indications to the contrary (and test cases that expose
-incorrect behaviour) are very welcome.
-.Sh SEE ALSO
-.Xr Test::More 1 ,
-.Xr Test::Harness 1 ,
-.Xr prove 1
-.Sh STANDARDS
-.Nm
-requires a
-.St -isoC-99
-compiler. Some of the
-.Nm
-functionality is implemented as variadic macros, and that functionality
-was not formally codified until C99. Patches to use
-.Nm
-with earlier compilers that have their own implementation of variadic
-macros will be gratefully received.
-.Sh HISTORY
-.Nm
-was written to help improve the quality and coverage of the FreeBSD
-regression test suite, and released in the hope that others find it
-a useful tool to help improve the quality of their code.
-.Sh AUTHORS
-.An "Nik Clayton" Aq nik@ngo.org.uk ,
-.Aq nik@FreeBSD.org
-.Pp
-.Nm
-would not exist without the efforts of
-.An "Michael G Schwern" Aq schqern@pobox.com ,
-.An "Andy Lester" Aq andy@petdance.com ,
-and the countless others who have worked on the Perl QA programme.
-.Sh BUGS
-Ideally, running the tests would have no side effects on the behaviour
-of the application you are testing. However, it is not always possible
-to avoid them. The following side effects of using
-.Nm
-are known.
-.Bl -bullet -offset indent
-.It
-stdout is set to unbuffered mode after calling any of the
-.Fn plan_*
-functions.

+ * tap - Test Anything Protocol
+ *
+ * The tap package produces simple-to-parse mainly-human-readable test
+ * output to assist in the writing of test cases. It is based on the
+ * (now-defunct) libtap, which is based on Perl's CPAN TAP module. Its
+ * output can be parsed by a harness such as CPAN's Prove.
+ *
+ * CCAN testcases are expected to output the TAP format, usually using
+ * this package.
+ *
+ * For more information about TAP, see:
+ * http://en.wikipedia.org/wiki/Test_Anything_Protocol
+ *
+ * Based on the original libtap, Copyright (c) 2004 Nik Clayton.
+ *
+ * Example:
+ * #include <string.h>
+ * #include "tap/tap.h"
+ *
+ * // Run some simple (but overly chatty) tests on strcmp().
+ * int main(int argc, char *argv[])
+ * {
+ * const char a[] = "a", another_a[] = "a";
+ * const char b[] = "b";
+ * const char ab[] = "ab";
+ *
+ * plan_tests(4);
+ * diag("Testing different pointers (%p/%p) with same contents",
+ * a, another_a);
+ * ok1(strcmp(a, another_a) == 0);
+ *
+ * diag("'a' comes before 'b'");
+ * ok1(strcmp(a, b) < 0);
+ * ok1(strcmp(b, a) > 0);
+ *
+ * diag("'ab' comes after 'a'");
+ * ok1(strcmp(ab, a) > 0);
+ * return exit_status();

+.Sh NAME
+.Nm tap
+.Nd write tests that implement the Test Anything Protocol
+.Sh SYNOPSIS
+.In tap.h
+.Sh DESCRIPTION
+The
+.Nm
+library provides functions for writing test scripts that produce output
+consistent with the Test Anything Protocol. A test harness that parses
+this protocol can run these tests and produce useful reports indicating
+their success or failure.
+.Ss PRINTF STRINGS
+In the descriptions that follow, for any function that takes as the
+last two parameters
+.Dq Fa char * , Fa ...
+it can be assumed that the
+.Fa char *
+is a
+.Fn printf
+-like format string, and the optional arguments are values to be placed
+in that string.
+.Ss TEST PLANS
+.Bl -tag -width indent
+.It Xo
+.Ft void
+.Fn plan_tests "unsigned int"
+.Xc
+.It Xo
+.Ft void
+.Fn plan_no_plan "void"
+.Xc
+.It Xo
+.Ft void
+.Fn plan_skip_all "char *" "..."
+.Xc
+.El
+.Pp
+You must first specify a test plan. This indicates how many tests you
+intend to run, and allows the test harness to notice if any tests were
+missed, or if the test program exited prematurely.
+.Pp
+To do this, use
+.Fn plan_tests .
+The function will cause your program to exit prematurely if you specify
+0 tests.
+.Pp
+In some situations you may not know how many tests you will be running, or
+you are developing your test program, and do not want to update the
+.Fn plan_tests
+parameter every time you make a change. For those situations use
+.Fn plan_no_plan .
+It indicates to the test harness that an indeterminate number
+of tests will be run.
+.Pp
+Both
+.Fn plan_tests
+and
+.Fn plan_no_plan
+will cause your test program to exit prematurely with a diagnostic
+message if they are called more than once.
+.Pp
+If your test program detects at run time that some required functionality
+is missing (for example, it relies on a database connection which is not
+present, or a particular configuration option that has not been included
+in the running kernel) use
+.Fn plan_skip_all ,
+passing as parameters a string to display indicating the reason for skipping
+the tests.
+.Ss SIMPLE TESTS
+.Bl -tag -width indent
+.It Xo

+.Ft unsigned int

+.Xc
+.It Xo

+.Fn pass "char *" "..."

+.It Xo
+.Ft unsigned int
+.Fn fail "char *" "..."
+.Xc
+.El
+.Pp
+Tests are implemented as expressions checked by calls to the
+.Fn ok
+and
+.Fn ok1
+macros. In both cases
+.Fa expression
+should evaluate to true if the test succeeded.
+.Pp
+.Fn ok
+allows you to specify a name, or comment, describing the test which will
+be included in the output.
+.Fn ok1
+is for those times when the expression to be tested is self
+explanatory and does not need an associated comment. In those cases
+the test expression becomes the comment.
+.Pp
+These four calls are equivalent:
+.Bd -literal -offset indent
+int i = 5;
+
+ok(i == 5, "i equals 5"); /* Overly verbose */
+ok(i == 5, "i equals %d", i); /* Just to demonstrate printf-like
+ behaviour of the test name */
+ok(i == 5, "i == 5"); /* Needless repetition */
+ok1(i == 5); /* Just right */
+.Ed
+.Pp
+It is good practice to ensure that the test name describes the meaning
+behind the test rather than what you are testing. Viz
+.Bd -literal -offset indent
+ok(db != NULL, "db is not NULL"); /* Not bad, but */
+ok(db != NULL, "Database conn. succeeded"); /* this is better */
+.Ed
+.Pp
+.Fn ok
+and
+.Fn ok1
+return 1 if the expression evaluated to true, and 0 if it evaluated to
+false. This lets you chain calls from
+.Fn ok
+to
+.Fn diag
+to only produce diagnostic output if the test failed. For example, this
+code will include diagnostic information about why the database connection
+failed, but only if the test failed.
+.Bd -literal -offset indent
+if (!ok(db != NULL, "Database conn. succeeded")) {
+ diag("Database error code: %d", dberrno);
+}
+.Ed
+.Pp
+You also have
+.Fn pass
+and
+.Fn fail .
+From the Test::More documentation:
+.Bd -literal -offset indent
+Sometimes you just want to say that the tests have passed.
+Usually the case is you've got some complicated condition
+that is difficult to wedge into an ok(). In this case,
+you can simply use pass() (to declare the test ok) or fail
+(for not ok).
+
+Use these very, very, very sparingly.
+.Ed
+.Pp
+These are synonyms for ok(1, ...) and ok(0, ...).
+.Ss SKIPPING TESTS
+.Bl -tag -width indent
+.It Xo
+.Ft void
+.Fn skip "unsigned int" "char *" "..."
+.Xc
+.It Xo
+.Fn skip_if "expression" "unsigned int" "char *" "..."
+.Xc
+.El
+.Pp
+Sets of tests can be skipped. Ordinarily you would do this because
+the test can't be run in this particular testing environment.
+.Pp
+For example, suppose some tests should be run as root. If the test is
+not being run as root then the tests should be skipped. In this
+implementation, skipped tests are flagged as being ok, with a special
+message indicating that they were skipped. It is your responsibility
+to ensure that the number of tests skipped (the first parameter to
+.Fn skip )
+is correct for the number of tests to skip.
+.Pp
+One way of implementing this is with a
+.Dq do { } while(0);
+loop, or an
+.Dq if( ) { } else { }
+construct, to ensure that there are no additional side effects from the
+skipped tests.
+.Bd -literal -offset indent
+if(getuid() != 0) {
+ skip(1, "because test only works as root");
+} else {
+ ok(do_something_as_root() == 0, "Did something as root");
+}
+.Ed
+.Pp
+A convenient macro is provided to assist with this. The previous example could
+be re-written as follows.
+.Bd -literal -offset indent
+skip_if(getuid() != 0, 1, "because test only works as root") {
+ ok(do_something_as_root() == 0, "Did something as root");
+}
+.Ed
+.Ss MARKING TESTS AS Dq TODO
+.Bl -tag -width indent
+.It Xo
+.Ft void
+.Fn todo_start "char *" "..."
+.Xc
+.It Xo
+.Ft void
+.Fn todo_end "void"
+.Xc
+.El
+.Pp
+Sets of tests can be flagged as being
+.Dq TODO .
+These are tests that you expect to fail, probably because you haven't
+fixed a bug, or finished a new feature yet. These tests will still be
+run, but with additional output that indicates that they are expected
+to fail. Should a test start to succeed unexpectedly, tools like
+.Xr prove 1
+will indicate this, and you can move the test out of the todo
+block. This is much more useful than simply commenting out (or
+.Dq #ifdef 0 ... #endif )
+the tests.
+.Bd -literal -offset indent
+todo_start("dwim() not returning true yet");
+
+ok(dwim(), "Did what the user wanted");
+
+todo_end();
+.Ed
+.Pp
+Should
+.Fn dwim
+ever start succeeding you will know about it as soon as you run the
+tests. Note that
+.Em unlike
+the
+.Fn skip_*
+family, additional code between
+.Fn todo_start
+and
+.Fn todo_end
+.Em is
+executed.
+.Ss SKIP vs. TODO
+From the Test::More documentation;
+.Bd -literal -offset indent
+If it's something the user might not be able to do, use SKIP.
+This includes optional modules that aren't installed, running
+under an OS that doesn't have some feature (like fork() or
+symlinks), or maybe you need an Internet connection and one
+isn't available.
+
+If it's something the programmer hasn't done yet, use TODO.
+This is for any code you haven't written yet, or bugs you have
+yet to fix, but want to put tests in your testing script
+(always a good idea).
+.Ed
+.Ss DIAGNOSTIC OUTPUT
+.Bl -tag -width indent
+.It Xo
+.Fr void
+.Fn diag "char *" "..."
+.Xc
+.El
+.Pp
+If your tests need to produce diagnostic output, use
+.Fn diag .
+It ensures that the output will not be considered by the TAP test harness.
+.Fn diag
+adds the necessary trailing
+.Dq \en
+for you.
+.Bd -literal -offset indent
+diag("Expected return code 0, got return code %d", rcode);
+.Ed
+.Ss EXIT STATUS
+.Bl -tag -width indent
+.It Xo
+.Fr int
+.Fn exit_status void
+.Xc
+.El
+.Pp
+For maximum compatability your test program should return a particular
+exit code. This is calculated by
+.Fn exit_status
+so it is sufficient to always return from
+.Fn main
+with either
+.Dq return exit_status();
+or
+.Dq exit(exit_status());
+as appropriate.
+.Sh EXAMPLES
+The
+.Pa tests
+directory in the source distribution contains numerous tests of
+.Nm
+functionality, written using
+.Nm .
+Examine them for examples of how to construct test suites.
+.Sh COMPATABILITY
+.Nm
+strives to be compatible with the Perl Test::More and Test::Harness
+modules. The test suite verifies that
+.Nm
+is bug-for-bug compatible with their behaviour. This is why some
+functions which would more naturally return nothing return constant
+values.
+.Pp
+If the
+.Lb libpthread
+is found at compile time,
+.Nm
+.Em should
+be thread safe. Indications to the contrary (and test cases that expose
+incorrect behaviour) are very welcome.
+.Sh SEE ALSO
+.Xr Test::More 1 ,
+.Xr Test::Harness 1 ,
+.Xr prove 1
+.Sh STANDARDS
+.Nm
+requires a
+.St -isoC-99
+compiler. Some of the
+.Nm
+functionality is implemented as variadic macros, and that functionality
+was not formally codified until C99. Patches to use
+.Nm
+with earlier compilers that have their own implementation of variadic
+macros will be gratefully received.
+.Sh HISTORY
+.Nm
+was written to help improve the quality and coverage of the FreeBSD
+regression test suite, and released in the hope that others find it
+a useful tool to help improve the quality of their code.
+.Sh AUTHORS
+.An "Nik Clayton" Aq nik@ngo.org.uk ,
+.Aq nik@FreeBSD.org
+.Pp
+.Nm
+would not exist without the efforts of
+.An "Michael G Schwern" Aq schqern@pobox.com ,
+.An "Andy Lester" Aq andy@petdance.com ,
+and the countless others who have worked on the Perl QA programme.
+.Sh BUGS
+Ideally, running the tests would have no side effects on the behaviour
+of the application you are testing. However, it is not always possible
+to avoid them. The following side effects of using
+.Nm
+are known.

+ * Internet connection and one isn't available.

+ * skip(1, "Don't have SOME_FEATURE");

+ * will still be run, but with additional output that indicates that they are
+ * expected to fail.
+ *
+ * This way, should a test start to succeed unexpectedly, tools like prove(1)
+ * will indicate this and you can move the test out of the todo block. This
+ * is much more useful than simply commenting out (or '#if 0') the tests.
+ *
+ * From the Test::More documentation:
+ * If it's something the programmer hasn't done yet, use TODO. This is for
+ * any code you haven't written yet, or bugs you have yet to fix, but want to
+ * put tests in your testing script (always a good idea).
