Replace:

    "test": "jest",
    "updateSnapshot": "jest --updateSnapshot",
    "test:watch": "jest --watch",
    "coverage": "nyc jest && nyc report --reporter=html && open coverage/index.html || xdg-open coverage/index.html",

     "files": [
       "Tests/**/*.js",

     ],	
     "require": [		
       "babel-register",		
       "babel-polyfill",		
       "react-native-mock/mock",		
      "./Tests/Setup"		
    ],		
    "babel": "inherit"

in package.json added Jest node

return { isTablet: jest.fn() }
})
.mock('react-native-router-flux', () => {
return {
Actions: {'myScreen': () => {}},

const replace = require('ramda')
const forEach = require('ramda')

return {
t: (key, replacements) => {
let value = english[key]
if (!value) return key
if (!replacements) return value

  forEach((r) => {
    value = replace(`{{${r}}}`, replacements[r], value)
  }, keys(replacements))
