How to Master APP Testing: A Complete Skill Roadmap for New Test Engineers

Background After interviewing over a hundred professionals, the author observed that many testers with 1‑3 years of experience still lack core skills, often due to poor onboarding and team environments. The guide aims to help newcomers avoid this mismatch between tenure and competence.

Target Audience Individuals who can endure solitude, handle pressure, and possess the five "hearts"—specifically interns, fresh graduates, and engineers with 1‑2 years of experience.

Structure The guide is divided into three parts: testing knowledge and work explanation, tool/technology explanation, and APP testing content explanation.
