Master Thesis: AI-driven Test Failure Root Cause Analysis
Join our Team
About this opportunity
Software testing is a cornerstone of high-quality software delivery. However, test failures, especially those without clear root causes, lead to productivity loss, slow release cycles, and unreliable systems. This thesis investigates the use of Machine Learning (ML) and Large Language Models (LLMs) to analyze test failures and provide root cause insights across various testing stages (unit, integration, system), using data already collected from CI/CD pipelines and stored in S3.
What you will do
This thesis project revolves around building a Test Failure Root Cause Assistant powered by:
Existing CI test data (stored in AWS S3)Large Language Models like LLaMA-3, Mistral, or GPT variantsMetadata & features such as commit frequency, test flakiness, smell types, test suite duration, and build environmentEngineer features across multiple test levels (unit/integration/system).Train models to classify test failures or recommend root causes.
The skills you bring
Master´s student in computer science, computer engineering, or similar. Background in software testing and AI/ML is preferred.
