Use == for string comparison in tests
This replaces assertions that previously checked the return value of strcmp or compareTo, giving the testing framework a bit more information on the actual comparison happening, so it can show the actual strings it compares (instead of just the strcmp or compareTo return value). This changes errors like: REQUIRE( strcmp(str.c_str(), "ABC") == 0 ) with expansion: 220 == 0 into: REQUIRE( str == "ABC" ); with expansion: "XYZ" equals: "ABC" These changes were done using the following commands: sed -i 's/REQUIRE(strcmp(\([^,]*\).c_str(), \([^,]*\).c_str()) == 0)/REQUIRE(1円 == 2円)/g' * sed -i 's/REQUIRE(strcmp(\([^,]*\).c_str(), \([^,]*\)) == 0)/REQUIRE(1円 == 2円)/g' * sed -i 's/REQUIRE(\([^.]*\).compareTo(\([^)]*\)) == 0)/REQUIRE(1円 == 2円)/g' test_String.cpp test_characterAccessFunc.cpp test_operators.cpp test_substring.cpp Note that test_compareTo.cpp was excluded, since that actually needs to test compareTo. Additionally, two more lines were changed manually (one where the Arduino string and cstr were reversed, one where compareTo needed to return non-zero). Also note that this relies on the operator == defined by String itself, but since that is subject of its own tests, this should be ok to use in other tests.
