Test-Comp 2026

Test Suites

This file describes the contents of an archive of the 8th Competition on Software Testing (Test-Comp 2026). https://test-comp.sosy-lab.org/2026/

The competition was organized by Dirk Beyer, LMU Munich, Germany. More information is available in the following article: Dirk Beyer. Evaluating Tools for Automatic Software Testing (Report on Test-Comp 2026). In Proceedings of the 29th International Conference on Fundamental Approaches to Software Engineering (FASE 2026, Turin, Italy, April 11–16), 2026. Springer.

• LICENSE.txt: specifies the license
• README.txt: this file
• fileByHash/: This directory contains test suites (witnesses for coverage). Each test witness in this directory is stored in a file whose name is the SHA2 256-bit hash of its contents followed by the filename extension .zip. The format of each test suite is described on the format web page: https://gitlab.com/sosy-lab/software/test-format A test suite contains also metadata in order to relate it to the test task for which it was produced.
• witnessInfoByHash/: This directory contains for each test suite (witness) in directory witnessFileByHash/ a record in JSON format (also using the SHA2 256-bit hash of the witness as filename, with .json as filename extension) that contains the meta data.
• witnessListByProgramHashJSON/: For convenient access to all test suites for a certain program, this directory represents a function that maps each program (via its SHA2256-bit hash) to a set of test suites (JSON records for test suites as described above) that the test-generation tools have produced for that program. For each program for which test suites exist, the directory contains a JSON file (using the SHA2 256-bit hash of the program as filename, with .json as filename extension) that contains all JSON records for test suites for that program.

This is a reduced data set, in which the 140 000 largest test suites were excluded.

A similar data structure was used by SV-COMP and is described in the following article: Dirk Beyer. A Data Set of Program Invariants and Error Paths. In Proceedings of the 2019 IEEE/ACM 16th International Conference on Mining Software Repositories (MSR 2019, Montreal, Canada, May 26-27), pages 111-115, 2019.
