Name

       pg_tapgen - Generate schema TAP tests from an existing database

Usage

         pg_tapgen -d template1 > schema_test.sql

Description

       "pg_tapgen" is a command-line utility to generate pgTAP tests to validate a database
       schema by reading an existing database and generating the tests to match. Its use requires
       the installation of the DBI and DBD::Pg from CPAN or via a package distribution.

       Warning: These prerequisites are not validated by the pgTAP "Makefile", so you'll need to
       install them yourself. As a result, inclusion of this script in the pgTAP distribution is
       experimental. It may be moved to its own distribution in the future.

Options

         -d --dbname DBNAME        Database to which to connect.
         -U --username USERNAME    Username with which to connect.
         -h --host HOST            Host to which to connect.
         -p --port PORT            Port to which to connect.
         -v --verbose              Display output of test scripts while running them.
         -N --exclude-schema       Exclude a schema from the generated tests.
            --directory DIRECTORY  Directory to which to write the test files.
         -H --help                 Print a usage statement and exit.
         -m --man                  Print the complete documentation and exit.
         -V --version              Print the version number and exit.

Options Details

       "-d"
       "--dbname"
             pg_tapgen --dbname try
             pg_tapgen -d postgres

           The name of database to which to connect. Defaults to the value of the $PGDATABASE
           environment variable or to the system username.

       "-U"
       "--username"
             pg_tapgen --username foo
             pg_tapgen -U postgres

           PostgreSQL user name to connect as. Defaults to the value of the $PGUSER environment
           variable or to the operating system name of the user running the application.

       "-h"
       "--host"
             pg_tapgen --host pg.example.com
             pg_tapgen -h dev.local

           Specifies the host name of the machine on which the server is running. If the value
           begins with a slash, it is used as the directory for the Unix-domain socket. Defaults
           to the value of the $PGHOST environment variable or localhost.

       "-p"
       "--port"
             pg_tapgen --port 1234
             pg_tapgen -p 666

           Specifies the TCP port or the local Unix-domain socket file extension on which the
           server is listening for connections. Defaults to the value of the $PGPORT environment
           variable or, if not set, to the port specified at compile time, usually 5432.

       "--dir"
       "--directory"
           Directory to which to write test files. Defaults to the current directory.

       "-v"
       "--verbose"
             pg_tapgen --verbose
             pg_tapgen -v

           Display standard output of test scripts while running them. This behavior can also be
           triggered by setting the $TEST_VERBOSE environment variable to a true value.

       "-N"
       "--exclude-schema"
             pg_tapgen --exclude-schema contrib
             pg_tapgen -N testing -N temporary

           Exclude a schema from the test generation. "pg_tapgen" always ignores
           "information_schema", as it is also ignored by pgTAP. But if there are other schemas
           in the database that you don't need or want to test for in the database (because you
           run the tests on another database without those schemas, for example), use
           "--exclude-schema" to omit them. May be used more than once to exclude more than one
           schema.

       "-H"
       "--help"
             pg_tapgen --help
             pg_tapgen -H

           Outputs a brief description of the options supported by "pg_tapgen" and exits.

       "-m"
       "--man"
             pg_tapgen --man
             pg_tapgen -m

           Outputs this documentation and exits.

       "-V"
       "--version"
             pg_tapgen --version
             pg_tapgen -V

           Outputs the program name and version and exits.
