Can't use in a monorepo where each project has a different tsconfig.json

[Xapphire13]

ts-jest: 22.4.6
Structure of project

<rootDir>/
|- packages/
   |- package1/
      |- tsconfig.json
      |- src/
      |- tests/
         |- tsconfig.json
   |- package2/
      |- tsconfig.json
      |- src/
      |- tests/
         |- tsconfig.json

Issue

In a monorepo where each project has a tsconfig.json I cannot run jest as it cannot find a tsconfig.json

Expected behavior

ts-jest should use the tsconfig.json file closest to the file being tested that is applicable for the file (the same way tsc and tslint work).

Do you use jest projects here, or are they simply in subfolders?

I am using the jest projects config. Though I don't know if I'm doing it right =]. This is the first repo i've tried to make into a monorepo. Here is the repo link: https://github.com/Xapphire13/xapphire13.com

Have a look here.
I have posted my working solution there
jestjs/jest#3112

I figured out using a combination of trial and error and @nolazybits's solution that basically, each project needs to have its own jest configuration in the package.json to work.
