| // which compare given proto buffers with output appropriate message. |
| // |
| // How to use: |
| // You can pass the same type of proto buffer to EXPECT_PROTO_P?EQ, in |
| // "expect, actual" order. For convenience, the first argument of the macros, |
| // (i.e. expect), can take string literal. It'll be parsed appropriately. |
| // Assuming the proto P has members a and b; |
| // |
| // 1) |
| // P actual; |
| // ... (testing code) ... |
| // P expected; |
| // expected.set_a(expected_a); |
| // expected.set_b(expected_b); |
| // EXPECT_PROTO_EQ(expected, actual); |
| // |
| // 2) |
| // P actual; |
| // ... (testing code) ... |
| // EXPECT_PROTO_EQ("a: expected_a b: expected_b", actual); |
| // |
| // and so on. We can use EXPECT_PROTO_PEQ instead of EXPECT_PROTO_EQ. |
| // The difference between them is that EXPECT_PROTO_EQ compares all fields, |
| // but EXPECT_PROTO_PEQ checks only fields which is set in "expected". |
