A Modular Approach to Browser Compatibility Testing with Selenium, Virtual Machine Scheduling, and Custom UI Result Judgment
The article presents a three‑module architecture—Selenium for element interaction, a virtual‑machine scheduler to handle multiple browsers, and a custom result‑judgment component—to achieve reliable, automated web UI compatibility testing that overcomes the limitations of pure Selenium or manual methods.
Background : Traditional web browser compatibility testing often relies on manual checks or Selenium‑based automation, which struggle with coordinate‑based clicks, browser version coexistence, and UI visual verification.
Solution Overview : The proposed system consists of three core modules: Selenium for element identification and actions, a virtual‑machine scheduling layer to run isolated browser instances, and a custom result‑judgment engine that compares actual UI screenshots with expected images.
Portal : Users interact through a web portal to specify the target page, desired browsers, host settings, page actions, and optional expected result images; the portal forwards these parameters to the server control module.
Server Control : Based on the selected browsers, the server initiates the appropriate virtual machines via the scheduler and distributes the test configuration to each VM.
Virtual‑Machine Scheduling : This component launches isolated VMs, each pre‑installed with Selenium, the required browser, and its driver, thereby solving the browser coexistence problem.
Client (VM) : Inside each VM, a client program prepares the environment (sets host, launches Selenium, opens the browser), executes the scripted interactions, captures full‑page screenshots, and reports results back to the server.
Result Judgment : The server receives the actual screenshots, compares them with any provided expected images using similarity metrics, and presents the outcome through the portal; users can also save results for future regression testing.
