In a call "retrieve(account: string)", nobody checks the contents of "account". What if we could specify its type not just as a string, but as a formal language - say, a regex "0-9]+"? In our new paper "FLAT: Formal Languages as Types" with Fengmin Zhu, we do […] [Original post on mastodon.social]

FLAT: Formal Languages as Types
And Their Applications in Testing
FENGMIN ZHU, CISPA Helmholtz Center for Information Security, Germany
ANDREAS ZELLER, CISPA Helmholtz Center for Information Security, Germany

Programmers regularly use strings to encode many types of data, such as Unix file paths, URLs, and email addresses. They are
conceptually different, but existing mainstream programming languages treat them as the same string type. This is problematic:
the type system allows, for instance, malicious HTML text to be passed to a function expecting an email address.
To distinguish conceptually different string types and to avoid potential vulnerabilities, we regard formal languages as types
(FLAT), thereby restricting the set of valid strings using context-free grammars and, if needed, semantic constraints. Applying
this type-based approach, we offer a unified solution for string API documentation, input validation, malicious input detection,
language-based fuzzing, and test oracles, all at once, based on user-annotated formal language types and, if necessary, pre-
and post-conditions. We implement this idea and present FLAT-PY, a testing framework for Python. By attaching annotations
directly to Python code, FLAT-PY automatically performs runtime type checking via code instrumentation and reports any
detected type errors as soon as possible...

With more and more AI-generated code, comprehensive system testing becomes more important than ever. Our new paper "Language-Based Protocol Testing" (with Alexander Liggesmeyer and Pepe Zamudio), shows how to specify and test all details of how programs […] [Original post on mastodon.social]

Over the past decade, the automated generation of test inputs has made significant advances. Modern fuzzers and test generators easily
produce complex input formats that do systematically cover the input and execution space. Testing protocols, though, has remained a
frontier for automated testing, as a test generator has to interact with the program under test, producing messages that conform to
the current state of the system.
In this paper, we introduce language-based protocol testing, the first approach to specify, automatically test, and systematically cover
the full state and input space of protocol implementations. We specify protocols as interaction grammars—an extension of context-free
grammars that tag each message element with the communication party that is in charge of producing it. Interaction grammars embed
classical state models by unifying states, messages, and transitions all into nonterminals, and can be used for producing interactions as
well as parsing them, making them ideally suited for testing protocols.
By systematically
covering the interaction grammar and solving the associated constraints, FANDANGO achieves comprehensive coverage of the protocol
interactions, resulting in high code coverage and a thorough assessment of the program under test.

How do execution features relate to failures? In this new @ACM TOSEM paper, Marius Smytzek, Martin Eberlein, Lars Grunske, and I analyze which execution features beyond code coverage correlate best with failures and lead to accurate explanations of failure […] [Original post on mastodon.social]

Fault localization aims to identify code regions responsible for failures. Traditional techniques primarily correlate statement
execution with failures; however, program behavior involves diverse execution features, including variable values, branch
conditions, and definition-use pairs, which can provide richer diagnostic insights.
This paper comprehensively investigates execution features for fault understanding, addressing two complementary goals.
First, we conduct an empirical study of 310 bugs across 20 projects, analyzing 17 execution features and assessing their
correlation with failure outcomes. Our findings suggest that fault localization benefits from a broader range of execution
features: (1) Scalar pairs exhibit the strongest correlation with failures; (2) Beyond line executions, def-use pairs and functions
executed are key indicators for fault localization; and (3) Combining multiple features enhances effectiveness compared to
relying on individual features.
Second, building on these insights, we introduce a debugging approach that learns relevant features from labeled test
outcomes. The approach extracts fine-grained execution features and trains a decision tree to differentiate passing and failing
runs. The trained model generates fault diagnoses that explain the underlying causes of failures.
Our evaluation demonstrates that the generated diagnoses achieve high predictive accuracy. ...

Time to get serious again. New blog post "Reviewer-Author Collusion Rings and How to Fight Them": andreas-zeller.info/2025/12/07/Revi…

Recently, I again heard rumors of a _collusion ring_ in Software Engineering research – a group of authors and reviewers who agree to favorably review each other’s papers. I have no evidence that such a ring actually exists, but if I were to set up one, here’s how:

Use a messaging app like WhatsApp or WeChat to create a user group.
Give the group an innocuous name, say “Researchers in XYZ”, where XYZ is some currently popular research topic.
Post papers you wrote, discuss research results, complain about reviewers – in short, do whatever researchers talk about with each other.
So, what could be wrong with this? The important thing is that there is an implicit understanding that all group members will review each other’s papers favorably. Of course, this would never admitted or discussed in my group: First rule of Fight Club is you do not talk about Fight Club. If someone were to check the group, it’s just a regular chat group of XYZ lovers ...

This Friday at 11:00 am, I will be giving a talk on "Language-Based Software Testing" at Imperial College in London, covering our latest and greatest in testing systems with highly complex inputs and interactions. Details here: srg.doc.ic.ac.uk/seminars/25-12-zel…

Language-Based Software Testing
with José Antonio Zamudio Amaya, Marius Smytzek, Valentin Huber, Addison Crump, Alexi Turcotte, and many others

Random test input generators (fuzzers) have become the prime detectors of vulnerabilities in software. While generic fuzzers easily adapt to arbitrary programs under test, they offer very little possibilities to control or shape the generated inputs. In this talk, I present FANDANGO, a novel language-based fuzzer that combines grammars with predicates over input elements to produce inputs that satisfy all the given predicates. Examples of what such predicates can express include

input format constraints (“The length field should be equal to the length of the payload”)
code features (“Any variable used must be declared beforehand”)
statistical distributions (“Across all inputs, the voltage field must follow a Gaussian distribution, but never exceed 20 mV”)
data collections (“The credit-card-number field should come from the Python faker library”)
and more – actually, any property that can be expressed in a Python expression.

In our experiments, FANDANGO efficiently solved complex file formats and satisfied demanding predicates, up to full-fledged programming languages as test inputs for compilers. This opens the door towards personalized fuzzing, where testers can make use of their own knowledge and LLM knowledge to very effectively fuzz systems. Includes live demos!

Fandango is available at https://fandango-fuzzer.github.io/

Today is my 60th birthday – and what a journey it has been! I've been very lucky to always work in environments that shared my focus on long-term impact and usefulness, a strategy that has served me well. I'm deeply grateful to my family, friends, students, and colleagues who have all inspired and supported me along the way, and to my wonderful scientific community for its constant encouragement and guidance. (That includes you, reviewer 2!)

So, where's the party, and why are you not invited? As a true computer scientist, I value powers of two higher than multiples of ten. So you'll have to wait another four years, when I'll celebrate my (binary) 1,000,000th birthday – hopefully in the astounding new CISPA building. "Will you still be sending me a valentine, birthday greetings, bottle of wine? 🎶", when I'm sixty-four? Looking back – and looking forward!
