Graph Theory in Software Testing: Theory, Practice, and Optimization Strategies bridges the gap between abstract algorithms and real-world software testing challenges.

From modeling microservice dependencies to optimizing test case execution paths, this book explores how graph theory can elevate the way test engineers think, design, and automate. You'll learn to apply concepts like topological sorting, strongly connected components, articulation points, and graph coloring in practical scenarios — all with code examples in both Java and Python.

Whether you're building test frameworks, working in CI/CD pipelines, or designing test strategies for complex systems, this book gives you a toolkit for smarter, data-driven testing.

Key topics include:

• Graph modeling for microservices and test architecture
• Longest path and critical path analysis in test planning
• Graph coloring for parallel test scheduling
• Detecting flaky dependencies using Tarjan’s algorithm
• Real-world engineering case studies and source code

This book is written for software testers, SDETs, QA engineers, and developers who want to go beyond “point-and-click” testing and embrace algorithmic thinking in quality engineering.
