如果你希望用 JUnit 来测试一些性能问题,那么 JUnitBenchmark 可以帮到你,主要特性:
示例测试:
package org.javabenchmark; import com.carrotsearch.junitbenchmarks.AbstractBenchmark; import com.carrotsearch.junitbenchmarks.BenchmarkOptions; import javolution.text.TextBuilder; import org.junit.Test; /** * Benchmark for String concatenation. Compares StringBUilder (JDK) and * TextBuilder (Javolution). */ public class StringConcatenationBenchmark extends AbstractBenchmark { public static final long LOOPS_COUNT = 10000000; @Test @BenchmarkOptions(benchmarkRounds = 3, warmupRounds = 1) public void stringBuilderBenchmark() { StringBuilder builder = new StringBuilder(); for (long i = 0; i < LOOPS_COUNT; i++) { builder.append('i').append(i); } System.out.println(builder.toString().length()); } @Test @BenchmarkOptions(benchmarkRounds = 3, warmupRounds = 1) public void textBuilderBenchmark() { TextBuilder builder = new TextBuilder(); for (long i = 0; i < LOOPS_COUNT; i++) { builder.append('i').append(i); } System.out.println(builder.toString().length()); } }
