- Runtime generation using source string and Babel transform
- Using the Node `require()` function to read and parse fixture JSON
- Read in the fixture using Node's `fs` module and parse to object using `JSON.parse`
- Read and parse using `eval` 
- Read and parse using the `Function` constructor and invoking to parse
- Read compressed JSON, decompress using `zlib`, and use `Function` to parse
- Read binary file produced with `v8.serialize` and deserialize with `v8.deserialize`
- Read compressed binary file produced with `v8.serialize`, decompress using `zlib`, and deserialize with `v8.deserialize`
