Embedding quotes in strings

Yesterday I saw this (anonymized) in our codebase’s unit tests:

test_json_thing("{\"key\": 42, \"otherkey\": \"value\"}");

And then I looked elsewhere in our unit tests, and I saw this:

test_json_thing(R"( {"key": 42, "otherkey": "value"} )");

Frankly, these alternatives are both awful and I hate them. So when I wrote my unit test, I wrote this:

#define TEST_JSON_THING(...) test_json_thing(#__VA_ARGS__)

TEST_JSON_THING( {"key": 42, "otherkey": "value"} );
