Call for Papers

The increasing complexity, pervasiveness and inter-connection of software systems on the one hand, and the ever-shrinking development cycles and time-to-market on the other, make the automation of software test (AST) an urgent requirement today more than ever. Despite significant achievements both in theory and practice, AST remains a challenging research area.

Conference Theme

The AST 2020 conference theme is “Who tests the tests?”.

In software test automation, test code is written and maintained. It is generally accepted that disciplined procedures and quality standards should be applied in application development and coding.

However, somehow we do not demand the same rigour for the test code developed for testing those applications. Several recent empirical studies point out how tests are affected by many problems, bugs, unjustified assumptions, hidden dependencies from other tests or environment, flakiness, and performance issues. Because of such problems, test effectiveness is impacted and several false alarms are raised in regression testing that increase the test costs. The problem of unreliable test code is exacerbated in modern continuous integration and DevOps practices, demanding for fast fully automated recycling of test executions.

We invite contributions that focus on: i) getting a better understanding of the dimensions and characteristics of problems with unreliable, low-quality, test code; ii) automatically identifying test code smells or bugs; iii) providing solutions to prevent test bugs and test flakiness; and iv) improving the quality of test code.

Topic of Interest

Submissions on the AST 2020 theme are especially encouraged, but papers on other topics relevant to the automation of software test are also welcome.

Topics of interest include, but are not limited to the following:

  • Test automation of large, complex system
  • Metrics for testing - test efficiency, test coverage
  • Tools for model-based V&V
  • Test-driven development
  • Standardization of test tools
  • Test coverage metrics and criteria
  • Product line testing
  • Formal methods and theories for testing and test automation
  • Test case generation based on formal and semi-formal models
  • Testing with software usage models
  • Testing of reactive and object-oriented systems
  • Software simulation by models, forecasts of behavior and properties
  • Application of model checking in testing
  • Tools for security specification, models, protocols, testing and evaluation
  • Theoretical foundations of test automation
  • Models as test oracles; test validation with models
  • Testing anomaly detectors
  • Testing cyber physical systems

We are interested in the following aspects related to AST:

  1. Problem identification. Analysis and specification of requirements for AST, and elicitation of problems that hamper wider adoption of AST
  2. Methodology. Novel methods and approaches for AST in the context of up-to-date software development methodologies
  3. Technology. Automation of various test techniques and methods for test-related activities, as well as for testing various types of software
  4. Tools and Environments. Issues and solutions in the development, operation, maintenance and evolution of tools and environments for AST, and their integration with other types of tools and runtime support platforms
  5. Empirical studies, and Experience reports, and Industrial Contributions. Real experiences in using automated testing techniques, methods and tools in industry
  6. Visions of the future. Foresight and thought-provoking ideas for AST that can inspire new powerful research trends.


Three types of submissions are invited:

  • Regular Papers (up to 10 pages)
    • Research Paper
    • Industrial Case Study
  • Short Papers (up to 4 pages)
    • Research Paper
    • Industrial Case Study
    • Doctoral Student Research
  • Industrial Abstracts (up to 2 pages)

Regular papers include both Research papers that present research in the area of software test automation, and Industrial Case Studies that report on practical applications of test automation.

Regular papers must not exceed 10 pages for all materials (including the main text, appendices, figures, tables, and references).

Short papers also include both Research papers and Industrial Case Studies.

Short papers must not exceed 4 pages for all materials.

As short papers, doctoral students working on software testing are encouraged to submit their work. AST will have an independent session to bring doctoral students working on software testing, with experts assigned to each paper together, to discuss their research in a constructive and international atmosphere, and to prepare for defense exam. The first author in a submission must be the doctoral student and the second author the advisor. Authors of selected submissions will be invited to make a brief presentation followed by a constructive discussion in a session dedicated to doctoral students.

Industrial abstract talks are specifically conceived to promote industrial participation: We require the first author of such papers to come from industry. Authors of accepted papers get invited to give a talk with same time length and within same sessions as regular papers. Industrial abstracts must not exceed 2 pages for all materials.

The submission website is: https://easychair.org/conferences/?conf=ast2020

The format of the papers must follow the ACM formatting guidelines (https://www.acm.org/publications/proceedings-template) both for LaTEX and Word users. LaTEX users must use the provided acmart.cls and ACM-Reference-Format.bst without modification, enable the conference format in the preamble of the document (i.e., \documentclass[sigconf,review]{acmart}),and use the ACM reference format for the bibliography (i.e., \bibliographystyle{ACM-Reference-Format}).

Purchases of additional pages in the proceedings is not allowed.

Submissions must be unpublished original work and should not be under review or submitted elsewhere while being under consideration.

The accepted regular and short papers, case studies, and industrial abstracts will be published in the ICSE 2020 Co-located Event Proceedings and included in the IEEE and ACM Digital Libraries. Authors of accepted papers are required to register and present their accepted paper at the conference in order for the paper to be included in the proceedings and the Digital Libraries.

The official publication date is the date the proceedings are made available in the ACM or IEEE Digital Libraries.

This date may be up to two weeks prior to the first day of ICSE 2020. The official publication date affects the deadline for any patent filings related to published work.

Combating Flaky Tests

Abstract. Testing is the most common approach in practice to check software. Regression testing checks software changes. A key challenge for regression tests is to detect software bugs and fail when a change introduces a bug, signaling to the developer to fix it. However, an emerging challenge is that the tests must also not fail when there is no bug in the change. Unfortunately, some tests, called flaky, can non-deterministically pass or fail on the same software, even when it has no bug. Such flaky tests give false alarms to developers about the existence of bugs. A developer may end up wasting time trying to fix bugs not relevant to the recent changes the developer made. I will present some work done by my group and our collaborators to alleviate the problem of flaky tests.

CROWN 2.0: Automated Test Generation for Industrial Embedded Software - 17 Years Journey from Research To Product

Abstract. Automated software testing techniques such as software model checking and concolic testing have been popular in research communities for the last few decades. However, such advanced techniques are not yet successfully applied to industrial software. For fruitful technology transfer from academia to industry, we have to build a bridge to cross the obstacles such as lack of trained field engineers, hidden (and non-negligible) costs to apply automated techniques, different levels of software quality pursued by different industry sectors and so on.  In this talk, I will discuss lessons learned from my 17 years’ experience of applying automated software testing techniques to industrial embedded software such as Samsung smartphones, LG home appliances, and Hyundai automotive software. Also, I will share my experience of starting an automated software testing company V+Lab, which develops an automated test generation tool CROWN 2.0 that targets safety critical systems such as automotive vehicles, airplanes, and defense systems.

Speaker: Moonzoo Kim (SW Testing & Verification Group, & KAIST, Daejeon, South Korea)

Short bio: Moonzoo Kim is an associate professor in School of Computing at KAIST and the CEO of V+Lab. His research focuses on automated software testing and debugging techniques.

He has applied automated software testing techniques (e.g., concolic testing and fuzzing) to real-world industrial projects and detected critical bugs in Samsung flash memory and smartphones, LG home appliances, and Hyundai automobiles and so on. Based on such success from the industrial projects, he founded V+Lab  ( https://vpluslab.kr ) which develops automated test generation tools for safety critical domains (e.g., automobiles, airplanes, and defense systems).

He has been actively serving research communities as a conference organization committee member (e.g., ICSE SEIP 2020 chair, ISSTA workshop 2019 co-chair, ICSE New Faculty Symp. 2016 co-chair, ASE 2015 publication chair) and an editorial board member for STVR and JCSE. He was invited as a keynote speaker at FACS 2018 and received a Test of Time Award at Runtime Verification 2019 and a best paper award at ICST 2018.
