pgTAP is a unit testing framework for PostgreSQL written in PL/pgSQL and PL/SQL. It includes a comprehensive collection of TAP-emitting assertion functions, as well as the ability to integrate with other TAP-emitting test frameworks. It can also be used in the xUnit testing style. For detailed documentation, see the documentation in doc/pgtap.mmd or online.

To build it, just do this:

make
make installcheck
make install

If you encounter an error such as:

"Makefile", line 8: Need an operator

You need to use GNU make, which may well be installed on your system as gmake:

gmake
gmake install
gmake installcheck

If you encounter an error such as:

make: pg_config: Command not found

Or:

Makefile:52: *** pgTAP requires PostgreSQL 8.1 or later. This is .  Stop.

Be sure that you have pg_config installed and in your path. If you used a package management system such as RPM to install PostgreSQL, be sure that the -devel package is also installed. If necessary tell the build process where to find it:

env PG_CONFIG=/path/to/pg_config make && make install && make installcheck

And finally, if all that fails (and if you're on PostgreSQL 8.1, it likely will), copy the entire distribution directory to the contrib/ subdirectory of the PostgreSQL source tree and try it there without pg_config:

env NO_PGXS=1 make && make install && make installcheck

If you encounter an error such as:

ERROR:  must be owner of database regression

You need to run the test suite using a super user, such as the default "postgres" super user:

make installcheck PGUSER=postgres

Once pgTAP is installed, you can add it to a database. If you're running PostgreSQL 9.1.0 or greater, it's a simple as connecting to a database as a super user and running:

CREATE EXTENSION pgtap;

If you've upgraded your cluster to PostgreSQL 9.1 and already had pgTAP installed, you can upgrade it to a properly packaged extension with:

CREATE EXTENSION pgtap FROM unpackaged;

For versions of PostgreSQL less than 9.1.0, you'll need to run the installation script:

psql -d mydb -f /path/to/pgsql/share/contrib/pgtap.sql

If you want to install pgTAP and all of its supporting objects into a specific schema, use the PGOPTIONS environment variable to specify the schema, like so:

PGOPTIONS=--search_path=tap psql -d mydb -f pgTAP.sql

pgTAP requires PostgreSQL 8.1 or higher, with 8.4 or higher recommended for full use of its API. It also requires PL/pgSQL.
