ts-jest is a TypeScript preprocessor with source map support for Jest that lets you use Jest to test projects written in TypeScript.
It supports all features of TypeScript including type-checking. Read more about Babel7 + preset-typescript vs TypeScript (and ts-jest).
We are not doing semantic versioning and 23.10 is a re-write, run npm i -D ts-jest@"<23.10.0" to go back to the previous version |
