Cross-Browser Web Testing Tool with Tolerance-Based Attribute Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cross-browser web application testing is challenging due to differences in how web browsers render web pages, making it difficult to identify and validate rendering discrepancies across various browsers.
Innovation Solution
A system and method that allows users to select multiple web browsers, specify test fields and attributes, set tolerance values for rendering errors, and generate reports on comparisons between browsers, including error, warning, and pass flags, to highlight rendering differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If comprehensive attribute comparison is performed across multiple browsers, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The testing system segments the web page into multiple test fields (elements, attributes, and values) that can be independently compared across browsers. Each test field represents a discrete unit of comparison, allowing the system to manage complexity by breaking down the overall rendering comparison into manageable segments rather than attempting to analyze the entire page as a single unit.
Solution Approach 2:
The system allows users to specify tolerance values for different attributes, changing the comparison parameters dynamically. By adjusting tolerance thresholds, the system can adapt the measurement precision to match the specific requirements of different attributes (e.g., stricter tolerance for text content, more lenient tolerance for positioning), thereby improving overall measurement accuracy without uniformly increasing system complexity across all comparisons.
2Loss of information
If detailed error reporting is generated for all attributes, then information completeness is improved, but loss of information increases due to report complexity
Solution Approach 1:
The reporting system applies local quality by providing detailed error information specifically for test fields that exhibit rendering discrepancies, while summarizing or omitting details for fields that pass comparison. Error flags, warning flags, and pass flags are selectively generated based on the actual comparison results, ensuring that comprehensive error reporting is focused only where needed rather than uniformly applied to all attributes, thus reducing overall report complexity.
Solution Approach 2:
The system generates simplified copy representations of the rendering discrepancies through standardized flag indicators (error flags, warning flags, pass flags) that convey the essence of comparison results without requiring detailed analysis of every attribute difference. These flag copies provide a condensed summary that preserves the critical information about rendering issues while avoiding the complexity of reporting every single attribute variation in detail.
3Manufacturing precision
If tolerance values are set for all attributes, then manufacturing precision is improved, but ease of operation decreases
Solution Approach 1:
The system implements partial action by allowing users to set tolerance values only for specific attributes that require precise control, rather than requiring tolerance configuration for all possible attributes. Users can selectively apply tolerance values to critical attributes (such as text content or key positioning) while leaving other attributes to use default comparison settings, thereby achieving manufacturing precision for important elements without the operational burden of configuring every single attribute.
4Productivity
If multiple browsers are tested simultaneously, then productivity is improved, but device complexity increases
Solution Approach 1:
The testing system merges multiple browser testing operations into a single unified comparison framework. By combining the rendering outputs of multiple browsers and comparing them against each other and against expected values within the same test execution, the system achieves improved productivity through simultaneous multi-browser testing while managing complexity through a unified comparison engine that handles all browsers consistently rather than requiring separate testing processes for each browser.

AI summary
A system for cross-browser testing of one or more web applications may include receiving user selection of web browsers, one or more test fields each corresponding to a specified web element, one or more attributes each corresponding to a specified property of a web element, and a tolerance value for each of the one or more selected attributes. A system for cross-browser testing may be configured to compare a selected attribute of each selected test field within a web page rendered by one selected browser with a corresponding attribute of a corresponding test field within the web page rendered by another selected browser relative to a selected tolerance value, and generate a report of the comparison. A system for cross-browser testing may be configured for comparisons independent of a human language used and may include a language translation module.
