Microbenchmarking is a widely used form of performance testing in Java software. A
microbenchmark repeatedly executes a small chunk of code while collecting measurements …

Refactoring aims at improving the maintainability of source code without modifying its
external behavior. Previous works proposed approaches to recommend refactoring …

Software benchmarks are only as good as the performance measurements they yield.
Unstable benchmarks show high variability among repeated measurements, which causes …

Regression testing comprises techniques which are applied during software evolution to
uncover faults effectively and efficiently. While regression testing is widely studied for …

Background Agile principles play a pivotal role in modern software development.
Unfortunately, the assessment of non-functional software properties, such as performance …

Performance is a crucial non-functional requirement of many software systems. Despite the
widespread use of performance testing, developers still struggle to construct and evaluate …

Software performance changes are costly and often hard to detect pre-release. Similar to
software testing frameworks, either application benchmarks or microbenchmarks can be …

Performance testing aims at uncovering efficiency issues of software systems. In order to be
both effective and practical, the design of a performance test must achieve a reasonable …

Performance testing aims to ensure the operational efficiency of software systems. However,
many factors influencing the efficacy and adoption of performance tests in practice are not …

Performance problems in applications should ideally be detected as soon as they occur, ie,
directly when the causing code modification is added to the code repository. To this end …
