46 // ASSERT_PRED_FORMAT1(pred_format, v1)
47 // ASSERT_PRED_FORMAT2(pred_format, v1, v2)
48 // ...

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:

64 // streaming to std::ostream.
