Simple configuration of Jest with ts-jest produces error \"ReferenceError: describe is not defined\" in runtime. Here minimal example: https://github.com/PFight/jest-ts-desc
Or you can add the type definitions for jest like this in your tsconfig: "include": ["node_modules/@types", "test/**/**.ts"],
"include": ["node_modules/@types", "test/**/**.ts"],
And add the types via installing it with npm -i @types/jest
I can't push to your repo though creating a PR is not possible..
