Problem Statement\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn large web applications, even minor changes to HTML structure, CSS rules, or JavaScript logic can affect the behavior of other components. Manual verification of every scenario takes considerable time and does not always cover every possible combination of states, data, and user actions. Another challenge involves identifying errors that occur only under specific conditions, such as asynchronous operations, screen dimension changes, repeated page loading, or interaction between multiple components. Without systematic testing and performance analysis, technical issues may accumulate and complicate future web application maintenance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2. Solution\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAlign Collection presents a systematic approach to web application verification at different levels, from individual functions to complete user workflows. You will learn to design test cases, create isolated checks, simulate external dependencies, and analyze test execution results. A substantial part of the program focuses on DOM, forms, asynchronous workflows, API communication, responsive styling, and inter-component communication. The final project combines testing, diagnostics, performance verification, and error analysis into a comprehensive web interface quality evaluation system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3.
