Database Testing Richard Dallaway notes about database unit testing inspired me the realization of the DbUnit framework. I think this is a very good text about this subject. Hopefully he gave me the permission to present excerpts from his notes here. The original text is much longer and I strongly suggest you to read it as well. Database Testing

Intro to SW Test Automation Today,‘Test automation’ is a much talked about topic in the world of software testing and quality. In this article Saket Godase discusses the basics of test automation. What is test automation?
Software testing is an investigation conducted to provide stakeholders with information about the quality of the product or service under test. [ 1 ] Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Test techniques include, but are not limited to, the process of executing a program or application with the intent of finding software bugs (errors or other defects). Software testing can be stated as the process of validating and verifying that a computer program/application/product:
Test-driven development ( TDD ) is a software development process that relies on the repetition of a very short development cycle: first the developer writes an (initially failing) automated test case that defines a desired improvement or new function, then produces the minimum amount of code to pass that test, and finally refactors the new code to acceptable standards. Kent Beck , who is credited with having developed or 'rediscovered' the technique, stated in 2003 that TDD encourages simple designs and inspires confidence. [ 1 ] Test-driven development is related to the test-first programming concepts of extreme programming , begun in 1999, [ 2 ] but more recently has created more general interest in its own right. [ 3 ] Programmers also apply the concept to improving and debugging legacy code developed with older techniques.

In software engineering , behavior-driven development (abbreviated BDD ) is a software development process based on test-driven development (TDD) . [ 1 ] [ 2 ] Behavior-driven development combines the general techniques and principles of TDD with ideas from domain-driven design and object-oriented analysis and design to provide software developers and business analysts with shared tools and a shared process to collaborate on software development. [ 1 ] [ 3 ] Although BDD is principally an idea about how software development should be managed by both business interests and technical insight, the practice of BDD does assume the use of specialized software tools to support the development process. [ 2 ] Although these tools are often developed specifically for use in BDD projects, they can be seen as specialized forms of the tooling that supports test-driven development. The tools serve to add automation to the ubiquitous language that is a central theme of BDD. [ edit ] History
In computer programming , unit testing is a method by which individual units of source code , sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures, are tested to determine if they are fit for use. [ 1 ] Intuitively, one can view a unit as the smallest testable part of an application. In procedural programming a unit could be an entire module but is more commonly an individual function or procedure. In object-oriented programming a unit is often an entire interface, such as a class, but could be an individual method. [ 2 ] Unit tests are created by programmers or occasionally by white box testers during the development process.
Acceptance testing In engineering and its various subdisciplines , acceptance testing is a test conducted to determine if the requirements of a specification or contract are met. It may involve chemical tests , physical tests , or performance tests . In systems engineering it may involve black-box testing performed on a system (for example: a piece of software , lots of manufactured mechanical parts, or batches of chemical products) prior to its delivery. [ 1 ] Software developers often distinguish acceptance testing by the system provider from acceptance testing by the customer (the user or client) prior to accepting transfer of ownership.
