Function EqFailure

tests/gtest/gtest-all.cc:2806–2838

Constructs and returns the message for an equality assertion (e.g. ASSERT_EQ, EXPECT_STREQ, etc) failure. The first four parameters are the expressions used in the assertion and their values, as strings. For example, for ASSERT_EQ(foo, bar) where foo is 5 and bar is 6, we have: lhs_expression: "foo" rhs_expression: "bar" lhs_value: "5" rhs_value: "6" The ignoring_case parameter is tr

// *_STRCASEEQ*.  When it's true, the string "Ignoring case" will
// be inserted into the message.
