Selenium中如何验证点击元素后是否成功跳转至目标页面？

Alright, let's walk through how to properly validate this submission flow so you can tell apart the different scenarios where clicking Page A's submit button doesn't take you to Page B. Here's a practical, step-by-step approach:

1. Initial Submission Check #

First, click the submit button on Page A and observe what happens right away:

• If you land directly on Page B: The happy path is working as intended—no further checks needed here.
• If you remain on Page A: This is where you need to dig deeper to distinguish between the two root causes.

2. Distinguish Frontend Validation Failure vs. Redirected Page A #

Check for Frontend Validation Issues #

These are the most common reasons the submit button won't trigger a navigation:

• Look for inline error feedback: Red text next to form fields, pop-up toast messages, or highlighted invalid inputs that tell you what's wrong (e.g., "Email format is invalid").
• Open your browser's dev tools (F12 or Ctrl+Shift+I on Windows/Linux, Cmd+Opt+I on Mac) and check the Console tab for any frontend script errors or validation-related logs.
• Try fixing any obvious input issues (like filling in missing required fields) and resubmit. If the button now takes you to Page B, it was definitely a validation failure.

Verify if It's a Redirected Fresh Page A #

If there are no validation errors, the page might have been redirected back to Page A intentionally. To confirm:

• Check the address bar: Even if the URL stays the same, a redirect will trigger a full page reload. You can often see a brief flash or the browser's loading indicator.
• Use the Network tab in dev tools: Look for a POST request to the submit endpoint, followed by a 3xx redirect response (like 302) that points back to Page A's URL.
• Compare the page state: A freshly redirected Page A will usually have cleared form inputs (unless the backend repopulates them for convenience) or reset temporary UI state (like collapsed sections, active tabs, or selected filters).
• Check the Performance tab in dev tools to confirm a full page load occurred—this will show a new entry in the timeline for Page A.

3. Edge Case Testing #

To cover all scenarios:

• Test with input combinations that are known to trigger the "redirect back to Page A" business rule (e.g., specific user permissions, valid but incomplete data that requires additional action on Page A).
• Simulate network delays (using dev tools' Network throttling) to ensure you don't misinterpret a slow redirect as a validation failure.
