Description: Outlier testing is an essential component of automated testing, designed to evaluate how a system handles unexpected or extreme data that significantly deviates from the norm. These tests are crucial for ensuring the robustness and reliability of applications, as outliers can cause errors, failures, or unexpected behaviors in software. By simulating extreme conditions, such as unusual inputs or data limits, testers can identify vulnerabilities and ensure that the system responds appropriately, whether by rejecting the input, handling the error in a controlled manner, or adjusting its behavior to adapt to the situation. Implementing these tests not only improves software quality but also contributes to a better user experience by preventing situations that could lead to data loss or malfunction. In an agile development environment, where changes are frequent and rapid, outlier testing becomes an indispensable tool for maintaining system integrity throughout its lifecycle.
