Description

Seems like React < 15.3 has been broken in enzyme for awhile.

See https://travis-ci.org/airbnb/enzyme/builds/508248173 / https://github.com/airbnb/enzyme/tree/react_15_0_1 - I've managed to drop the number of failing tests from about 400 to about 60.

Research direction
The issue reports that React versions <15.3 are broken in enzyme. The author has started work on a branch (react 15 0 1) and reduced failing tests from about 400 to 60. To proceed, examine the remaining test failures on that branch and the referenced Travis CI build (508248173). The fixes likely involve adjusting enzyme's internal handling of older React APIs. Because the issue is over 5 years old and no recent activity, reassess whether the problem still exists and if the proposed branch is still viable.
