Possible disadvantages of BackstopJS

• Complex Setup for Beginners
  The initial setup can be complex for those who are not familiar with headless browsers or visual testing concepts, potentially resulting in a steep learning curve.
• Performance Overhead
  Running visual tests can be resource-intensive, which might affect performance, especially with a large number of scenarios and comparisons.
• Maintenance Effort
  Creating and maintaining test scenarios can require ongoing effort as the application evolves, including updating baselines and handling false positives.
• Limited to Visual Testing
  BackstopJS focuses solely on visual regression testing and doesn't provide broader testing capabilities like functionality or performance testing, necessitating additional tools for comprehensive test coverage.
• Screenshot Differences
  Slight, acceptable differences in rendering between test runs can lead to false positives, requiring fine-tuning and adjustments for threshold settings.
