I upgraded a react native project from 0.57.8 to 0.63.4
Before the upgrade my jest tests were passing. Now I can't run any of them, even if I take them all out and put this only this in foo.test.js:
describe("helpers", () => {
it("passes", () => expect(1).toEqual(1));
});
relevant parts of package.json:
{
"name": "x",
"version": "8.2.0",
"private": true,
"scripts": {
...
"test": "jest ./src/",
},
"jest": {
"preset": "react-native"
},
"dependencies": {
"@babel/runtime": "^7.5.5",
...
"babel-jest": "^27.0.6",
...
"jest": "^27.0.6",
"jest-cli": "^27.0.6",
"react-native": "0.63.4",
"react-native-cli": "^2.0.1",
...
},
"devDependencies": {
"@babel/core": "^7.8.4",
"@babel/plugin-proposal-class-properties": "^7.14.5",
"@babel/runtime": "^7.8.4",
...
},
}
When I run the test:
$ npm test
> jest ./src/
FAIL src/lib/foo.test.js
● Test suite failed to run
