Download the PHP package hi-media/pdo-tools without Composer

pdo-tools

pdo-tools simplifies the build of a database for testing purposes and allows you to easily verify the contents of a database after operations.

Specifically pdo-tools is a small PHP class extending PHPUnit_Framework_TestCase (see PHPUnit) allowing to dynamically build entirely new test databases, with:

• no database, schema or privileges prerequisites,
• keep the last N built databases (customizable, for monitoring and debugging),
• easy fixtures,
• additional specific assertions,
• powerful combination of PDO/PDOStatement mock objects and callbacks, e.g. to mock a third-party database,
• ready-to-use with Jenkins and local PHPUnit.

Installation

1. Class autoloading and dependencies are managed by Composer so install it following the instructions on Composer: Installation - *nix or just run the following command:

2. Add dependency to Himedia\PDOTools into require section of your composer.json:

   and run php composer.phar install from the terminal into the root folder of your project.

3. Include Composer's autoloader:

Usage

Instantiation

Example:

where /path/to/buildfile.php (example here) is a build file describing how to create a fresh database, roles/users and schemas, with listing of fixtures to load

Simple test

Example including:

• fixture loading,
• comparison between result of executed SQL query, converted into CSV, and a CSV file,
• clean up

where /path/to/fixture.sql is a typical SQL dump file, gzipped or not.

Note that in CSV files, following field's values are converted:

• '∅' ⇒ null
• 't' ⇒ true
• 'f' ⇒ false

Mocking a third-party database

In this example, successives calls to PDOStatement::fetch() method on the third-party database…

• will return content of /path/to/fixture.csv file like calls to PDOStatement::fetch(PDO::FETCH_ASSOC) if initial statement of PDO::query() was 'SELECT … FROM A', and false if no more lines in specified CSV,
• will return results of successives calls to the user callback if initial statement of PDO::query() was 'SELECT … FROM B'

All queries are internally normalized to simplify matching.

Documentation

API documentation is generated by ApiGen in the doc/api folder.

Versioning & Git branching model

For transparency into our release cycle and in striving to maintain backward compatibility, Padocc's engine is maintained under the Semantic Versioning guidelines. We'll adhere to these rules whenever possible.

The git branching model used for development is the one described and assisted by twgit tool: https://github.com/Twenga/twgit.
