Languages and Tools for Next Generation Testing Workshop - LANGETI 2020

Every year, new ideas arise in programming and software development that facilitate new capabilities for software systems. However, aspects of software systems development (testing) are overlooked. The LANGETI workshop intends to serve as an open discussion platform for practitioners and researchers to share their ideas and the results of their work around the topic of automated testing for next generation applications.

LANGETI aims to disrupt the current state of workshops through the introduction of more dynamic and involved working sessions. We will divide the workshop sessions into three main components. First, we will provide a space to share high quality research ideas focused on the subject of testing languages and tools for next generation platforms and systems. Second, we will have hands-on sessions to offer a practical overview of tools. Finally, we will have an open panel for early career researchers and nascent projects in a “pechakucha” style of presentation. These presentations will specifically aim to spark conversation about researchers’ ideas, to be further discussed in small panels at the end of each day.

Intended Audience

The workshop looks to bring together practitioners and researchers at different stages of their career. The workshop contents should be of interest for people working on software testing in general. Moreover, with the hands-on format planned for the workshop we expect to capture the interest of both newcomers to the field and industrial practitioners alike.


The workshop will take place over 2 days. The first day will commence with an initial theory-oriented keynote, followed by regular paper presentations. Each of these presentations will undergo the normal peer review process expected of research papers at academic SE venues. The second day will open with a keynote-style tutorial, followed by practical sessions showcasing a wide variety of software testing tools ranging from prototypes to mature systems. These sessions will be structured as short tutorials, where attendants will have the opportunity to download, and use the tool in their own machines, following a guided example. Across both days of the workshop time will be dedicated for the “pecha kucha” spotlights, wherein the presentations on the first day will be more theoretical in nature, and those on the second day will be more tool oriented.


An explicit goal of the workshop is to open a platform for new or visionary testing techniques. We are also interested in tool-oriented submissions, where participants would present and demo their testing solutions. Therefore, contributions to the workshop should ideally include, in addition to a detailed discussion of the proposed approach (for example by defining the models, mechanisms, or testing strategies underlying that approach), a discussion of how the proposed approach on software testing could influence or be influenced by other approaches and perspectives. Although it is not mandatory, we encourage the authors to include preliminary results of using the proposed approaches/tools. We encourage submissions that make contributions related to the topics of testing-oriented programming languages and tools tailored for new technologies, or new application domains.

We will accept contributions in the following forms:

  1. Technical Workshop Papers (up to 6 pages including references): Technical workshop papers should explicitly discuss new testing techniques as relevant to the workshop topics listed below. Submissions of work in early stages is encouraged, although we also suggest authors include a preliminary evaluation of their proposed techniques or discussions of the implications of findings from empirical studies.

  2. Research Abstracts (up to 2 pages including references): We encourage both academic researchers and industrial practitioners to submit extended abstracts that describe early or existing ideas about testing approaches to be discussed during the workshop. Abstracts should clearly state the purpose of the approach, research/implementation challenges, and research agenda.

  3. Testing Tool Extended Abstracts (up to 2 pages including references): We encourage both academic researchers and industrial practitioners to submit extended abstracts that describe new or existing testing tools to be showcased during the workshop. Abstracts should clearly state the purpose of the tool, and provide an overview of its functionality.

The topics of interest of the workshop include, but are not limited to:

Papers must be written in English, provided as PDF documents, and follow the ESEC/FSE 2020 Format and Submission Guidelines, i.e., ACM Conference Format (10 point font, Times New Roman font family, numeric citation style). Submission will be managed through the LANGETI 2020 EasyChair conference management system.

Accepted papers will be published as part of ACM’s Digital Library. Submissions will undergo standard peer reviewing by at least three members of the program committee. Shepherding will be a possibility after notification. All accepted papers will be allocated a presentation slot. All paper submissions are expected to present their topic together with a hands-on mini tutorial about the use/implementation of the tool/algorithm presented in their paper.

Important Dates

Paper submission: August 17, 2020
Paper notification: September 13, 2020
Camera-ready submission: September 18, 2020
Workshop date: November 9, 2020

Follow-up Plans

This will be the first edition of the LANGETI workshop, which we aim to evolve into a self-sustaining workshop and a mainstay of the ESEC/FSE conference. With LANGETI we will build a community for software testing researchers and practitioners to come together. We will create an online software testing portal associated with LANGETI. The idea of the portal is to use it as a hub gathering information about authors and tools that participate in the workshop. Overtime, profiles for other researchers, and other testing tools can be added to the webpage.

In addition to this testing portal, we will record the “pecha kucha” talks, which will be added to the permanent workshop webpage. These talks will serve as a roadmap and archive of emerging ideas in software testing. We will add an editorial note of the workshop summarizing the main discussions (together with a detailed discussions memoir) of the workshop.
