// Regression test for gtest_pred_impl.h
//
// This file is generated by a script and quite long.  If you intend to
// learn how Google Test works by reading its unit tests, read
// gtest_unittest.cc instead.
//
// This is intended as a regression test for the Google Test predicate
// assertions.  We compile it as part of the gtest_unittest target
// only to keep the implementation tidy and compact, as it is quite
// involved to set up the stage for testing Google Test using Google
// Test itself.
//
// Currently, gtest_unittest takes ~11 seconds to run in the testing
// daemon.  In the future, if it grows too large and needs much more
// time to finish, we should consider separating this file into a
// stand-alone regression test.
