46// ASSERT_PRED_FORMAT1(pred_format, v1)
47// ASSERT_PRED_FORMAT2(pred_format, v1, v2)
48// ...
49//
50// where pred_format is a function or functor that takes n (in the
51// case of ASSERT_PRED_FORMATn) values and their source expression
52// text, and returns a testing::AssertionResult. See the definition
53// of ASSERT_EQ in gtest.h for an example.
54//
55// If you don't care about formatting, you can use the more
56// restrictive version:
57//
58// ASSERT_PRED1(pred, v1)
59// ASSERT_PRED2(pred, v1, v2)
60// ...
61//
62// where pred is an n-ary function or functor that returns bool,
63// and the values v1, v2, ..., must support the << operator for
64// streaming to std::ostream.
65//
66// We also define the EXPECT_* variations.
67//
68// For now we only support predicates whose arity is at most 5.
69// Please email googletestframework@googlegroups.com if you need
70// support for higher arities.
