jemul8 takes an object-oriented approach to emulation. Primarily an educational tool, it aims to provide a detailed description of the internal workings of an IBM-compatible PC.
It aims to reflect computer science concepts, such as Fetch-Decode-Execute, in a largely abstract context, although the only instruction set currently supported is Intel's IA-32/x86 architecture.
To run the tests, visit /tests/bdd/ in the browser. For example, to run the tests from the demo environment on jemul8.com, visit http://jemul8.com/tests/bdd/ to run the Mocha tests (warning: this is slow - it is recommended to run the tests locally.)
