ts-jest: Ts-jest is failing to locate the tsconfig when being run from inside yarn workspace (or lerna)

Issue ts-jest is failing to locate the tsconfig when being run from inside yarn workspace (or lerna)

More info: ts jest is looking for tsconfig from the node_modules he is installed it and up. In yarn workspace/lerna usually it will be hoisted to the top level directory of the project. See: https://github.com/kulshekhar/ts-jest/blob/7b15180e4a6f1f7903ff1e5fcefb40dbc52a9370/src/utils.ts#L116-L129
jest is also get hoisted, but still it manage to find the correct package.json

ts-jest should be able to pick up the tsconfig inside it

beforeAll(() => {
  const tempDir = tempy.directory()
  process.chdir(tempDir)

Try adding cleanup step and change the working directory back
