Karma TypeScript Preprocessor 2

A Karma preprocessor plugin that transpiles TypeScript files using the gulp-typescript compiler with incremental compilation for fast rebuilds. Version 1.2.1 is the latest stable release. It relies on tsconfig.json for primary configuration, supports custom compiler overrides, sourcemaps via gulp-sourcemaps, and virtual path transformations. Notable features include very fast incremental rebuilds, good error reporting, and the ability to exclude .d.ts files. However, it has several unsupported TypeScript config options (sourceMap, rootDir, watch, project) and may face compatibility issues with newer Karma or TypeScript versions.
