Running a global test setup before each test in Jest

You could use setupFilesAfterEnv (which replaces setupTestFrameworkScriptFile, deprecated from jest version 24.x) which will run before each test

// package.json
{
  // ...
  "jest": {
    "setupFilesAfterEnv": ["<rootDir>/setupTests.js"]
  }
}

And in setupTests.js, you can directly write:

global.beforeEach(() => {
  ...
});

global.afterEach(() => {
   ...
});
