All your tests are commented out, is this the official example ? https://github.com/lelandrichardson/enzyme-example-jest/blob/master/src/__tests__/Foo-test.js

Uncommenting jest tests (shallow render) throws this error:

Using Jest CLI v0.8.2, jasmine1 Running 1 test suite...Warning: React.createElement: type should not be null, undefined, boolean, or number. It should be a string (for DOM elements) or a ReactClass (for composite components). FAIL src/tests/Foo-test.js (0.912s) ● A suite › it contains spec with an expectation

Seems like there are problems with Jest and Enzyme :( https://github.com/facebook/jest/issues/1175

This can be solved updating jest-cli and using "import Foo from "./Foo" and use "jest.unmock()" instead of jest.dontMock() https://facebook.github.io/jest/docs/api.html#jest-unmock-modulename

I still get errors when trying to add uncomment mount test. I updated jest-cli to version 17.0.0 + I changed to jest.unmock('../Foo');

I get the following error:

src/tests/Foo-test.js Console
