Testing is an important task within software development. To write test cases and integrate them into an automated test suite requires a significant amount of work. Given a set of requirements and specifications of a software, testing is needed to ...

In this paper, we present the latest version 3.0.0 of EvoMaster, an open-source search-based fuzzer aimed at Web APIs. We discuss and present all its recent improvements, including advanced white-box heuristics, advanced search algorithms, support ...

Microservices is now becoming a promising architecture to build large-scale web services in industry. Due to the high complexity of enterprise microservices, industry has an urgent need to have a solution to enable automated testing of such systems. ...

Due to its importance and widespread use in industry, automated testing of REST APIs has attracted major interest from the research community in the last few years. However, most of the work in the literature has been focused on black-box fuzzing. ...

The Graph Query Language (GraphQL) is a powerful language for application programming interface (API) manipulation in web services. It has been recently introduced as an alternative solution for addressing the limitations of RESTful APIs. This article ...

In the dynamic landscape of Search-Based Software Engineering (SBSE), tools and algorithms are continually improved, possibly making past experimental insights outdated. This could happen if a newly designed technique has side-effects compared to ...

RESTful APIs are a type of web service that are widely used in industry. In the past few years, a lot of effort in the research community has been spent in designing novel techniques to automatically fuzz those APIs to find faults in them. Many real ...

JavaScript is one of the most popular programming languages. However, its dynamic nature poses several challenges to automated testing techniques. In this paper, we propose an approach and open-source tool support to enable white-box testing of JavaScript ...

C# is one of the most widely used programming languages. However, to the best of our knowledge, there has been no work in the literature aimed at enabling search-based software testing techniques for applications running on the .NET platform, like ...

Remote Procedure Call (RPC) is a communication protocol to support client-server interactions among services over a network. RPC is widely applied in industry for building large-scale distributed systems, such as Microservices. Modern RPC frameworks ...

Research in software testing often involves the development of software prototypes. Like any piece of software, there are challenges in the development, use and verification of such tools. However, some challenges are rather specific to this ...

Unit testing is a critical part of software development process, ensuring the correctness of basic programming units in a program (e.g., a method). Search-based software testing (SBST) is an automated approach to generating test cases. SBST generates ...

Nowadays, many companies use RESTful web services to develop their enterprise applications. These web services typically interact with databases. In REST, resource handling is a fundamental concept, where resources are manipulated by exposing HTTP ...

Search-based software testing (SBST) has been shown to be an effective technique to generate test cases automatically. Its effectiveness strongly depends on the guidance of the fitness function. Unfortunately, a common issue in SBST is the so-called flag ...

Automated system test generation for web/enterprise systems requires either a sequence of actions on a GUI (e.g., clicking on HTML links and form buttons) or direct HTTP calls when dealing with web services (e.g., REST and SOAP). When doing white-box ...

Automated system test generation for web/enterprise systems requires either a sequence of actions on a GUI (e.g., clicking on HTML links), or direct HTTP calls when dealing with web services (e.g., REST and SOAP). However, web/enterprise systems do ...

In this paper we revisit the field of search-based software testing (SBST) in the context of its technological maturity. We highlight some successes with respect to tools, hybrid approaches, extensions and industry adoption. We then discuss some open ...

This tutorial covers the basics of how to use statistical tests to evaluate and compare search-algorithms, in particular when applied on software engineering problems. Search-algorithms like Hill Climbing and Genetic Algorithms are randomised. Running ...

Automated Test Case Generation (ATCG) is an important topic in Software Testing, with a wide range of techniques and tools being used in academia and industry. While their usefulness is widely recognized, due to the labor-intensive nature of the task, ...

A key indicator of the health and quality of any evolutionary algorithm is the landscape of its search. By analyzing the landscape one can determine the peaks (local maxima) where significant solutions exist. In this paper we examine the landscape for ...
