From bcba6ed25244b36a7975a7c1bc429732d54818d1 Mon Sep 17 00:00:00 2001 From: Kurt Korbatits Date: Mon, 19 Mar 2012 14:54:16 +1000 Subject: Added extra tests to json benchmark - Added toByteArray() and fromByteArray() benchmark tests. Performance tests to measure QVariantMap to bytearray and bytearray to QVariantMap. Use case: Interprocess communications via local socket Change-Id: If5e94ff870890b2ebb665f3cc38f5c33b34547f4 Reviewed-by: Rohan McGovern --- .../corelib/json/tst_bench_qtbinaryjson.cpp | 32 ++++++++++++++++++++++ 1 file changed, 32 insertions(+) (limited to 'tests/benchmarks/corelib/json') diff --git a/tests/benchmarks/corelib/json/tst_bench_qtbinaryjson.cpp b/tests/benchmarks/corelib/json/tst_bench_qtbinaryjson.cpp index 2253d00778..e4e10ba2ba 100644 --- a/tests/benchmarks/corelib/json/tst_bench_qtbinaryjson.cpp +++ b/tests/benchmarks/corelib/json/tst_bench_qtbinaryjson.cpp @@ -58,6 +58,8 @@ private Q_SLOTS: void parseNumbers(); void parseJson(); void parseJsonToVariant(); + void toByteArray(); + void fromByteArray(); }; BenchmarkQtBinaryJson::BenchmarkQtBinaryJson(QObject *parent) : QObject(parent) @@ -127,6 +129,36 @@ void BenchmarkQtBinaryJson::parseJsonToVariant() } } +void BenchmarkQtBinaryJson::toByteArray() +{ + // Example: send information over a datastream to another process + // Measure performance of creating and processing data into bytearray + QBENCHMARK { + QVariantMap message; + message.insert("command", 1); + message.insert("key", "some information"); + message.insert("env", "some environment variables"); + QByteArray msg = QJsonDocument(QJsonObject::fromVariantMap(message)).toBinaryData(); + } +} + +void BenchmarkQtBinaryJson::fromByteArray() +{ + // Example: receive information over a datastream from another process + // Measure performance of converting content back to QVariantMap + // We need to recreate the bytearray but here we only want to measure the latter + QVariantMap message; + message.insert("command", 1); + message.insert("key", "some information"); + message.insert("env", "some environment variables"); + QByteArray msg = QJsonDocument(QJsonObject::fromVariantMap(message)).toBinaryData(); + + QBENCHMARK { + QVariantMap message; + message = QJsonDocument::fromBinaryData(msg, QJsonDocument::Validate).object().toVariantMap(); + } +} + QTEST_MAIN(BenchmarkQtBinaryJson) #include "tst_bench_qtbinaryjson.moc" -- cgit v1.2.3
