| − | :It's better to use an image that is designed to work on USB. There are some subtle differences between ISO9660 (cdrom) and USB format. USB installation from a host OS is tricky because it depends on windows. My thought was to include a USB installer in the CDROM distribution. You boot with CD then use that OS to install on a USB.

Test-Driven Development is a software development technique consisting of short iterations where new test cases covering the desired improvement or new functionality are written first, then the production code necessary to pass the tests is implemented, and finally the software is refactored to accommodate changes. The availability of tests before actual development ensures rapid feedback after any change.
Practitioners emphasize that test-driven development is a method of designing software, not merely a method of testing.
Test-Driven Development began to receive publicity in the early twenty-first century as an aspect of Extreme Programming, but more recently is creating more general interest in its own right.
Along with other techniques, the concept can also be applied to the improvement and removal of software defects from legacy code that was not developed in this way.
Test-driven development requires that an automated unit test, defining requirements of the code, is written before each aspect of the code itself. These tests contain assertions that are either true or false. Running the tests gives rapid confirmation of correct behaviour as the code evolves and is refactored. Testing frameworks based on the xUnit concept (see the list of unit testing frameworks for an exhaustive list) provide a mechanism for creating and running sets of automated test cases.
