In accessibility testing, distinguishing between false positives and false promises is crucial, as false positives involve incorrectly flagged issues that waste resources, while false promises mislead users into believing their products are accessible when they are not. Although false positives can be an inconvenience, they are manageable compared to the significant risks posed by false promises, which often arise when tools claim zero false positives by offering limited coverage. This creates a false sense of security, potentially leaving serious accessibility barriers undetected that could lead to user frustration, brand damage, and legal non-compliance. A comprehensive approach is necessary to effectively address accessibility issues, as focusing solely on minimizing false positives can result in overlooking critical problems that require manual audits, thus increasing workload and risk. BrowserStack aims to provide a balanced solution by focusing on coverage, completeness, and correctness to automatically detect real-world issues while keeping false positives minimal.
