Debugging a test case
=====================

These are the kinds of debugging information available from DejaGnu:

  1. Output controlled by test scripts themselves, explicitly allowed
     for by the test author.  This kind of debugging output appears in
     the detailed output recorded in the `TOOL.log' file.  To do the
     same for new tests, use the `verbose' procedure (which in turn
     uses the variable also called `verbose') to control how much
     output to generate.  This will make it easier for other people
     running the test to debug it if necessary.  Whenever possible, if
     `$verbose' is `0', there should be no output other than the output
     from `pass', `fail', `error', and `warning'.  Then, to whatever
     extent is appropriate for the particular test, allow successively
     higher values of `$verbose' to generate more information.  Be kind
     to other programmers who use your tests: provide for a lot of
     debugging information.

  2. Output from the internal debugging functions of Tcl and `expect'.
     There is a command line options for each; both forms of debugging
     output are recorded in the file `dbg.log' in the current directory.

     Use `--debug' for information from the `expect' level; it
     generates displays of the `expect' attempts to match the tool
     output with the patterns specified (*note Debug Log: Debug.).  This
     output can be very helpful while developing test scripts, since it
     shows precisely the characters received.  Iterating between the
     latest attempt at a new test script and the corresponding
     `dbg.log' can allow you to create the final patterns by "cut and
     paste".  This is sometimes the best way to write a test case.

     Use `--strace' to see more detail at the Tcl level; this shows how
     Tcl procedure definitions expand, as they execute.  The associated
     number controls the depth of definitions expanded; see the
     discussion of `--strace' in *Note Running the Tests: Invoking
     runtest.

  3. Finally, if the value of `verbose' is 3 or greater, `runtest'
     turns on the `expect' command `log_user'.  This command prints all
     `expect' actions to the `expect' standard output, to the detailed
     log file, and (if `--debug' is on) to `dbg.log'.

Adding a test case to a test suite
==================================

   There are two slightly different ways to add a test case. One is to
add the test case to an existing directory. The other is to create a new
directory to hold your test. The existing test directories represent
several styles of testing, all of which are slightly different; examine
the directories for the tool of interest to see which (if any) is most
suitable.

   Adding a GCC test can be very simple: just add the C code to any
directory beginning with `gcc.' and it runs on the next `runtest --tool
gcc'.

   To add a test to GDB, first add any source code you will need to the
test directory. Then you can either create a new `expect' file, or add
your test to an existing one (any file with a `.exp' suffix).  Creating
a new `.exp' file is probably a better idea if the test is
significantly different from existing tests. Adding it as a separate
file also makes upgrading easier. If the C code has to be already
compiled before the test will run, then you'll have to add it to the
`Makefile.in' file for that test directory, then run `configure' and
`make'.

   Adding a test by creating a new directory is very similar:

  1. Create the new directory. All subdirectory names begin with the
     name of the tool to test; e.g. G++ tests might be in a directory
     called `g++.other'. There can be multiple test directories that
     start with the same tool name (such as `g++').

  2. Add the new directory name to the `configdirs' definition in the
     `configure.in' file for the test suite directory. This way when
     `make' and `configure' next run, they include the new directory.

  3. Add the new test case to the directory, as above.

  4. To add support in the new directory for configure and make, you
     must also create a `Makefile.in' and a `configure.in'.  *Note What
     Configure Does: (configure.info)What Configure Does.

Hints on writing a test case
============================

   There may be useful existing procedures already written for your
test in the `lib' directory of the DejaGnu distribution.  *Note DejaGnu
Builtins: DejaGnu Builtins.

   It is safest to write patterns that match *all* the output generated
by the tested program; this is called "closure".  If a pattern does not
match the entire output, any output that remains will be examined by
the *next* `expect' command.  In this situation, the precise boundary
that determines which `expect' command sees what is very sensitive to
timing between the `expect' task and the task running the tested tool.
As a result, the test may sometimes appear to work, but is likely to
have unpredictable results.  (This problem is particularly likely for
interactive tools, but can also affect batch tools--especially for
tests that take a long time to finish.)  The best way to ensure closure
is to use the `-re' option for the `expect' command to write the
pattern as a full regular expressions; then you can match the end of
output using a `$'.  It is also a good idea to write patterns that
match all available output by using `.*\' after the text of interest;
this will also match any intervening blank lines.  Sometimes an
alternative is to match end of line using `\r' or `\n', but this is
usually too dependent on terminal settings.

   Always escape punctuation, such as `(' or `"', in your patterns; for
example, write `\('.  If you forget to escape punctuation, you will
usually see an error message like `extra characters after close-quote'.

   If you have trouble understanding why a pattern does not match the
program output, try using the `--debug' option to `runtest', and
examine the debug log carefully.  *Note Debug Log: Debug.

   Be careful not to neglect output generated by setup rather than by
the interesting parts of a test case.  For example, while testing GDB,
I issue a send `set height 0\n' command.  The purpose is simply to make
sure GDB never calls a paging program.  The `set height' command in GDB
does not generate any output; but running *any* command makes GDB issue
a new `(gdb) ' prompt.  If there were no `expect' command to match this
prompt, the output `(gdb) ' begins the text seen by the next `expect'
command--which might make *that* pattern fail to match.

   To preserve basic sanity, I also recommended that no test ever pass
if there was any kind of problem in the test case.  To take an extreme
case, tests that pass even when the tool will not spawn are misleading.
Ideally, a test in this sort of situation should not fail either.
Instead, print an error message by calling one of the DejaGnu procedures
`error' or `warning'.


File: dejagnu.info,  Node: Variables,  Prev: Hints,  Up: Tests

Special variables used by test cases
====================================

   Your test cases can use these variables, with conventional meanings
(as well as the variables saved in `site.exp' *note Setting `runtest'
defaults: Customizing.):

     *These variables are available to all test cases.*

`prms_id'
     The tracking system (e.g. GNATS) number identifying a corresponding
     bugreport.  (`0' if you do not specify it in the test script.)

`bug_id'
     An optional bug id; may reflect a bug identification from another
     organization.  (`0' if you do not specify it.)

`subdir'
     The subdirectory for the current test case.

     *These variables should never be changed. They appear in most
     tests.*

`expect_out(buffer)'
     The output from the last command. This is an internal variable set
     by `expect'.

`exec_output'
     This is the output from a `TOOL_load' command. This only applies
     to tools like GCC and GAS which produce an object file that must
     in turn be executed to complete a test.

`comp_output'
     This is the output from a `TOOL_start' command.  This is
     conventionally used for batch oriented programs, like GCC and GAS,
     that may produce interesting output (warnings, errors) without
     further interaction.

New Tools, Targets, or Hosts
****************************

   The most common ways to extend the DejaGnu framework are: adding a
suite of tests for a new tool to be tested; adding support for testing
on a new target; and porting `runtest' to a new host.

* Menu:

* Adding Tools::                How to add tests for a new tool
* Adding Targets::              How to add a new target

File: dejagnu.info,  Node: Adding Tools,  Next: Adding Targets,  Up: Extending

Writing tests for a new tool
============================

   In general, the best way to learn how to write (code or even prose)
is to read something similar.  This principle applies to test cases and
to test suites.  Unfortunately, well-established test suites have a way
of developing their own conventions: as test writers become more
experienced with DejaGnu and with Tcl, they accumulate more utilities,
and take advantage of more and more features of `expect' and Tcl in
general.

   Inspecting such established test suites may make the prospect of
creating an entirely new test suite appear overwhelming.  Nevertheless,
it is quite straightforward to get a new test suite going.

   There is one test suite that is guaranteed not to grow more elaborate
over time: both it and the tool it tests were created expressly to
illustrate what it takes to get started with DejaGnu.  The `example/'
directory of the DejaGnu distribution contains both an interactive tool
called `calc', and a test suite for it.  Reading this test suite, and
experimenting with it, is a good way to supplement the information in
this section.  (Thanks to Robert Lupton for creating `calc' and its
test suite--and also the first version of this section of the manual!)

   To help orient you further in this task, here is an outline of the
steps to begin building a test suite for a program EXAMPLE.

  1. Create or select a directory to contain your new collection of
     tests.  Change to that directory (shown here as `testsuite'):

          eg$ cd testsuite/

  2. Create a `configure.in' file in this directory, to control
     configuration-dependent choices for your tests.  So far as DejaGnu
     is concerned, the important thing is to set a value for the
     variable `target_abbrev'; this value is the link to the init file
     you will write soon.  (For simplicity, we assume the environment
     is Unix, and use `unix' as the value.)

     What else is needed in `configure.in' depends on the requirements
     of your tool, your intended test environments, and which
     `configure' system you use.  This example is a minimal
     `configure.in' for use with Cygnus Configure.  (For an alternative
     based on the FSF `autoconf' system, see the `calc' example
     distributed with DejaGnu.)  Replace EXAMPLE with the name of your
     program:

          # This file is a shell script fragment
          # for use with Cygnus configure.
          
          srctrigger="EXAMPLE.0"
          srcname="The DejaGnu EXAMPLE tests"
          
          # per-host:
          
          # per-target:
          
          # everything defaults to unix for a target
          target_abbrev=unix
          
          # post-target:

  3. Create `Makefile.in', the source file used by `configure' to build
     your `Makefile'.  Its leading section should as usual contain the
     values that `configure' may override:

          srcdir = .
          prefix = /usr/local
          
          exec_prefix = $(prefix)
          bindir = $(exec_prefix)/bin
          libdir = $(exec_prefix)/lib
          tooldir = $(libdir)/$(target_alias)
          
          datadir = $(exec_prefix)/lib/dejagnu
          
          RUNTEST = runtest
          RUNTESTFLAGS =
          FLAGS_TO_PASS =
          
          #### host, target, site specific Makefile frags come in here.

     This should be followed by the standard targets at your site.  To
     begin with, they need not do anything--for example, these
     definitions will do:


          all:
          
          info:
          
          install-info:
          
          install:
          uninstall:
          
          clean:
                  -rm -f *~ core *.info*

     It is also a good idea to make sure your `Makefile' can rebuild
     itself if `Makefile.in' changes, with a target like this (which
     works for either Cygnus or FSF Configure):

          Makefile : $(srcdir)/Makefile.in $(host_makefile_frag) \
                       $(target_makefile_frag)
                  $(SHELL) ./config.status

     You also need to include two targets important to DejaGnu: `check',
     to run the tests, and `site.exp', to set up the Tcl copies of
     configuration-dependent values.  The `check' target must run
     `runtest --tool EXAMPLE':

          check: site.exp all
                  $(RUNTEST) $(RUNTESTFLAGS) $(FLAGS_TO_PASS) \
                      --tool EXAMPLE --srcdir $(srcdir)

     The `site.exp' target should usually set up (among other things!) a
     Tcl variable for the name of your program:

          site.exp: ./config.status Makefile
                  @echo "Making a new config file..."
                  -@rm -f ./tmp?
                  @touch site.exp
          
                  -@mv site.exp site.bak
                  @echo "## these variables are automatically\
           generated by make ##" > ./tmp0
                  @echo "# Do not edit here. If you wish to\
           override these values" >> ./tmp0
                  @echo "# add them to the last section" >> ./tmp0
                  @echo "set host_os ${host_os}" >> ./tmp0
                  @echo "set host_alias ${host_alias}" >> ./tmp0
                  @echo "set host_cpu ${host_cpu}" >> ./tmp0
                  @echo "set host_vendor ${host_vendor}" >> ./tmp0
                  @echo "set target_os ${target_os}" >> ./tmp0
                  @echo "set target_alias ${target_alias}" >> ./tmp0
                  @echo "set target_cpu ${target_cpu}" >> ./tmp0
                  @echo "set target_vendor ${target_vendor}" >> ./tmp0
                  @echo "set host_triplet ${host_canonical}" >> ./tmp0
                  @echo "set target_triplet ${target_canonical}">>./tmp0
                  @echo "set tool binutils" >> ./tmp0
                  @echo "set srcdir ${srcdir}" >> ./tmp0
                  @echo "set objdir `pwd`" >> ./tmp0
                  @echo "set EXAMPLENAME EXAMPLE" >> ./tmp0
                  @echo "## All variables above are generated by\
           configure. Do Not Edit ##" >> ./tmp0
                          @cat ./tmp0 > site.exp
                  @sed < site.bak \
                         -e '1,/^## All variables above are.*##/ d' \
                         >> site.exp
                  -@rm -f ./tmp?

  4. Create a directory (in `testsuite/') called `config/':

          eg$ mkdir config

  5. Make an init file in this directory; its name must start with the
     `target_abbrev' value, so call it `config/unix.exp'.  This is the
     file that contains the target-dependent procedures; fortunately,
     most of them do not have to do very much in order for `runtest' to
     run.

     If EXAMPLE is not interactive, you can get away with this minimal
     `unix.exp' to begin with:

          proc foo_exit {} {}
          proc foo_version {} {}

     If EXAMPLE is interactive, however, you might as well define a
     start routine *and invoke it* by using an init file like this:

          proc foo_exit {} {}
          proc foo_version {} {}
          
          proc foo_start {} {
            global EXAMPLENAME
            spawn $EXAMPLENAME
            expect {
              -re "" {}
            }
          }
          foo_start

  6. Create a directory whose name begins with your tool's name, to
     contain tests:

          eg$ mkdir EXAMPLE.0

  7. Create a sample test file in `EXAMPLE.0'.  Its name must end with
     `.exp'; you can use `first-try.exp'  To begin with, just write
     there a line of Tcl code to issue a message:

          send_user "Testing: one, two...\n"

  8. Back in the `testsuite/' (top level) directory, run

          eg$ configure

     (You may have to specify more of a path, if a suitable `configure'
     is not available in your execution path.)

  9. You are now ready to triumphantly type `make check' or `runtest
     --tool EXAMPLE'.  You should see something like this:

          Test Run By rhl on Fri Jan 29 16:25:44 EST 1993
          
                          === EXAMPLE tests ===
          
          Running ./EXAMPLE.0/first-try.exp ...
          Testing: one, two...
          
                          === EXAMPLE Summary ===

     There is no output in the summary, because so far the example does
     not call any of the procedures that establish a test outcome.

 10. Begin writing some real tests.  For an interactive tool, you should
     probably write a real exit routine in fairly short order; in any
     case, you should also write a real version routine soon.

Adding a target
===============

   DejaGnu has some additional requirements for target support, beyond
the general-purpose provisions of Cygnus `configure'.  `runtest' must
actively communicate with the target, rather than simply generating or
managing code for the target architecture.  Therefore, each tool
requires an initialization module for each target.  For new targets, you
must supply a few Tcl procedures to adapt DejaGnu to the target.  This
permits DejaGnu itself to remain target independent.  *Note
Initialization module: Init Module, for a discussion of the naming
conventions that enable DejaGnu to locate and use init files.

   Usually the best way to write a new initialization module is to edit
an existing initialization module; some trial and error will be
required.  If necessary, you can use the `--debug' option to see what
is really going on.

   When you code an initialization module, be generous in printing
information controlled by the `verbose' procedure (*note DejaGnu
procedures: DejaGnu Builtins.).

   Most of the work is in getting the communications right.
Communications code (for several situations involving IP networks or
serial lines) is available in a DejaGnu library file, `lib/remote.exp'.
*Note DejaGnu Builtins: DejaGnu Builtins.

   If you suspect a communication problem, try running the connection
interactively from `expect'.  (There are three ways of running `expect'
as an interactive interpreter.  You can run `expect' with no arguments,
and control it completely interactively; or you can use `expect -i'
together with other command-line options and arguments; or you can run
the command `interpreter' from any `expect' procedure.  Use `return' to
get back to the calling procedure (if any), or `return -tcl' to make
the calling procedure itself return to its caller; use `exit' or
end-of-file to leave `expect' altogether.)  Run the program whose name
is recorded in `$connectmode', with the arguments in `$targetname', to
establish a connection.  You should at least be able to get a prompt
from any target that is physically connected.


File: dejagnu.info,  Node: Porting,  Prev: Adding Targets,  Up: Extending

Porting to a new host
=====================

   The task of porting DejaGnu is basically that of porting Tcl and
`expect'. Tcl and `expect', as distributed with DejaGnu, both use
`autoconf'; they should port automatically to most Unix systems.

   Once Tcl and `expect' are ported, DejaGnu should run.  Most system
dependencies are taken care of by using `expect' as the main command
shell.

Installing DejaGnu
******************

   Once you have the DejaGnu source unpacked and available, you must
first configure the software to specify where it is to run (and the
associated defaults); then you can proceed to installing it.

* Menu:

* Configuring DejaGnu::
* Installing DejaGnu::


File: dejagnu.info,  Node: Configuring DejaGnu,  Next: Installing DejaGnu,  Up: Installation

Configuring the DejaGnu test driver
===================================

   It is usually best to configure in a directory separate from the
source tree, specifying where to find the source with the optional
`--srcdir' option to `configure'. DejaGnu uses the GNU `autoconf' to
configure itself. For more info on using autoconf, read the GNU
autoconf manual. To configure, execute the `configure' program, no
other options are required. For an example, to configure in a seperate
tree for objects, execute the configure script from the source tree
like this:

     ../dejagnu-1.3/configure

   DejaGnu doesn't care at config time if it's for testing a native
system or a cross system. That is determined at runtime by using the
config files.

   You may also want to use the `configure' option `--prefix' to
specify where you want DejaGnu and its supporting code installed.  By
default, installation is in subdirectories of `/usr/local', but you can
select any alternate directory ALTDIR by including `--prefix=ALTDIR' on
the `configure' command line.  (This value is captured in the Makefile
variables `prefix' and `exec_prefix'.)

   Save for a small number of example tests, the DejaGnu distribution
itself does not include any test suites; these are available separately.
Test suites for the GNU compiler (testing both GCC and G++) and for the
GNU binary utilities are distributed in parallel with the DejaGnu
distribution (but packaged as separate files).  The test suite for the
GNU debugger is distributed in parallel with each release of GDB
itself, starting with GDB 4.9.  After configuring the top-level DejaGnu
directory, unpack and configure the test directories for the tools you
want to test; then, in each test directory, run `make' to build
auxiliary programs required by some of the tests.


File: dejagnu.info,  Node: Installing DejaGnu,  Prev: Configuring DejaGnu,  Up: Installation

Installing DejaGnu
==================

   To install DejaGnu in your filesystem (either in `/usr/local', or as
specified by your `--prefix' option to `configure'), execute

     eg$ make install

`make install' does these things for DejaGnu:

  1. Look in the path specified for executables (`$exec_prefix') for
     directories called `lib' and `bin'.  If these directories do not
     exist, `make install' creates them.

  2. Create another directory in the `lib' directory, called `dejagnu'.

  3. Copy the `runtest' shell script into `$exec_prefix/bin'.

  4. Copy all the library files (used to support the framework) into
     `$exec_prefix/lib/dejagnu'.

  5. Copy `runtest.exp' into `$exec_prefix/lib/dejagnu'.  This is the
     main Tcl code implementing DejaGnu.


   Each test suite collection comes with simple installation
instructions in a `README' file; in general, the test suites are
designed to be unpacked in the source directory for the corresponding
tool, and extract into a directory called `testsuite'.
