Tsdx: jest occasionally tries to transform json files -- needs better transform regex

[smashercosmo]

Current Behavior

Once in while I get the following warnings when I run 'tsdx test' command:

ts-jest[jest-transformer] (WARN) Got a unknown file type to compile (file: /Users/smashercosmo/Documents/projects/tmp-babel-plugin/node_modules/@babel/core/package.json). To fix this, in your Jest config change the `transform` key which value is `ts-jest` so that it does not match this kind of files anymore.
ts-jest[jest-transformer] (WARN) Got a unknown file type to compile (file: /Users/smashercosmo/Documents/projects/tmp-babel-plugin/node_modules/resolve/lib/core.json). To fix this, in your Jest config change the `transform` key which value is `ts-jest` so that it does not match this kind of files anymore.
ts-jest[jest-transformer] (WARN) Got a unknown file type to compile (file: /Users/smashercosmo/Documents/projects/tmp-babel-plugin/node_modules/globals/globals.json). To fix this, in your Jest config change the `transform` key which value is `ts-jest` so that it does not match this kind of files anymore.

Expected behavior

jest shouldn't try transforming json files

Suggested solution(s)

Probably 'json' should be added to transformIgnorePatterns in jest config

Is this still happening?

I'll check

Still getting this warnings with latest tsdx

[joemitchard]

I'm still finding this with v0.11.0. This usually occurs on the first run and then not again until the next build.

I am still seeing this issues in v0.12.3

Fixed by #513 . It will be out in the next release
