Is it possible to disable specific React warnings from Jest (using Create React App)

If you want to disable all warnings that meet some condition, keeping all other warnings, for all tests:

const originalWarn = console.warn.bind(console.warn)
beforeAll(() => {
  console.warn = (msg) => 
    !msg.toString().includes('componentWillReceiveProps') && originalWarn(msg)
})
afterAll(() => {
  console.warn = originalWarn
})

React codebase also contains expect(render(...)).toWarnDev(...), but that's not included in Jest documentation, you might need to investigate more if you want to use that feature.

Similar in concept to a previous answer, but a bit easier would be:

jest.spyOn(global.console, 'warn').mockImplementationOnce((message) => {
  if (!message.includes('componentWillReceiveProps')) {
    global.console.warn(message);
  }
});

If you wanted to do it across tests you could do:

let consoleSpy;

beforeAll(() => {
  consoleSpy = jest.spyOn(global.console, 'warn').mockImplementation((message) => {
    // same implementation as above
});

afterAll(() => consoleSpy.mockRestore());
