Goal
The path to "Web APIテスト技法"
Here is the reading path leading up to this book, derived from its dependencies and ordered from the fundamentals.
The path so far (7 books)
Why read this first: Once you can write basic Java syntax, the next step is to raise your sights from merely working code to code that is readable and easy to change. Clean Code provides principles for naming, function decomposition, and comments—building the sense of quality that is hard to acquire on your own.
Why read this first: Once you can write clean functions and classes, it's time to learn design patterns—named solutions to recurring design problems—through Java code. This book lets you experience the 23 GoF patterns in Java implementations, building a vocabulary of reusable designs and the ability to compose relationships between classes with clear intent.
Why read this first: Once you can wield class-level patterns, you broaden your view to how dependencies and boundaries are designed across the whole system. Clean Architecture offers the Dependency Rule—pushing details outward and keeping business rules at the center.
Why read this first: Knowing the OS-level mechanisms for processes, I/O, and memory lets you see what Spring abstracts away under the hood. This low-level understanding keeps the framework from being a black box and pays off when diagnosing performance issues and failures.
Why read this first: Once you can build applications with Spring, you start to feel the limits of framework-driven design centered on the database or the framework. Clean Architecture provides the Dependency Rule that keeps business rules independent of the framework, letting you choose a structure resilient to change over the long term.
Why read this first: Learning an architecture that controls the direction of dependencies makes you want testing principles that maximize the resulting testability. Unit Testing: Principles, Practices, and Patterns defines what a good test is, converting the loose coupling your architecture enables into testing value.

Why read this first: Having mastered unit testing principles, you broaden your view to a testing strategy for APIs that cross service boundaries. Testing Web APIs shows how to balance the upper layers of the test pyramid—integration, contract, end-to-end—securing the API reliability that unit tests alone can't protect.
