An Object Mother is a class in software testing that simplifies creating example objects for test scenarios ([[References#^666dad|Fowler, 2006]]). It tackles the complexity of managing interconnected test data like relationships, histories, and attributes by providing reusable, standardized fixtures. These *canned objects* are preconfigured to meet typical testing needs, ensuring consistency and reducing redundancy across test cases. This approach improves readability and allows testers to modify familiar objects for different scenarios, enhancing team and stakeholder understanding. Object Mothers are often organized by class type to handle varied data requirements efficiently and maintain clarity. However, they can lead to [[Tight coupling]], making tests overly dependent on specific data configurations and complicating updates. Maintaining Object Mothers can also be labor-intensive when classes or data structures evolve, requiring changes to both the objects and dependent tests. Despite these challenges, they are a valuable tool for managing test data in systems needing consistent and comprehensive datasets. Canned objects from the Object Mother can become familiar to the team and users ([[References#^666dad|Fowler, 2006]]), aligning with the [[Chunking theory]]. By encapsulating complex concepts into chunks, these objects make it unnecessary to remember each small component individually, reducing cognitive load, enhancing memory retention, and enabling faster processing, communication and shared understanding.
