pg_tapgen - Generate schema TAP tests from an existing database
pg_tapgen -d template1 > schema_test.sql
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.
-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. -H --help Print a usage statement and exit. -m --man Print the complete documentation and exit. -V --version Print the version number and exit.
pg_tapgen --dbname try pg_tapgen -d postgres
The name of database to which to connect. Defaults to the value of the
$PGDATABASEenvironment variable or to the system username.
pg_tapgen --username foo pg_tapgen -U postgres
PostgreSQL user name to connect as. Defaults to the value of the
$PGUSERenvironment variable or to the operating system name of the user running the application.
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
$PGHOSTenvironment variable or localhost.
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
$PGPORTenvironment variable or, if not set, to the port specified at compile time, usually 5432.
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_VERBOSEenvironment variable to a true value.
pg_tapgen --exclude-schema contrib pg_tapgen -N testing -N temporary
Exclude a schema from the test generation.
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-schemato omit them. May be used more than once to exclude more than one schema.
pg_tapgen --help pg_tapgen -H
Outputs a brief description of the options supported by
pg_tapgen --man pg_tapgen -m
Outputs this documentation and exits.
pg_tapgen --version pg_tapgen -V
Outputs the program name and version and exits.
