How To Protect Data Corruption By Testing ?

In todays information-driven enterprises, business critical information must be highly available

, from internal company-sensitive data to applications that manage crucial partner and customer relationships. Outages are costly in lost revenue and damaged reputation, and can be crippling to the business.

Without the ability to reliably maintain the integrity of data, computers would be useless. No one would rely on a system that scrambles bank accounts, garbles inventory data, or loses order information.Customer's business are critically dependant on every component of a computer system having a high degree of data Integrity. Data Integrity problems are most difficult to detect with traditional testing techniques.

Validating data integrity requires testers to think differently from other programmers. Testcases that programmatically determine when an error is encountered and consists in gathering diagnostic data are very powerful . Expose bugs that do not surface in cursory testing, such as memory management bugs, memory leaks, buffer overflows, etc.

Ensure that the application meets the performance baseline established during performance testing. This is done by running regression tests against the application at a specified maximum load. Avoid modifying your system registry or over-clock your hardware to yield performance boost unless you're absolutely sure of what you're doing. You don't wish to fry your computer.

Do not share or allow network access to any unknown users. Your computer data can be prone to theft and modification if anyone on the network can access your files freely. When you receive mails with attachment from unknown senders, do not open it. Attempt to create tests that have minimal requirements on configurations and other system attributes. Also keep the test execution simple. This makes it easy to port te tests from test system,share the tests with other testers and ensure lots of reuse.

In contrast, some emerging software disciplines such as extreme programming and the agile software development movement, adhere to a "test-driven software development" model. In this process, unit tests are written first, by the software engineers (often with pair programming in the extreme programming methodology). Of course these tests fail initially; as they are expected to. Then as code is written it passes incrementally larger portions of the test suites. The test suites are continuously updated as new failure conditions and corner cases are discovered, and they are integrated with any regression tests that are developed. Unit tests are maintained along with the rest of the software source code and generally integrated into the build process (with inherently interactive tests being relegated to a partially manual build acceptance process). The ultimate goal of this test process is to achieve continuous integration where software updates can be published to the public frequently.
