Debugging on video game consoles is usually done with special hardware such as this Xbox debug unit intended for developers. Debugging ranges in complexity from fixing simple errors to performing lengthy and tiresome tasks of data collection, analysis, and scheduling updates.
In software engineering, rubber duck debugging (or rubberducking) is a method of debugging code by articulating a problem in spoken or written natural language. The name is a reference to a story in the book The Pragmatic Programmer in which a programmer would carry around a rubber duck and debug their code by forcing themselves to explain it ...
Early in the game development process the testing team is small and focuses on daily feedback for new code. As the game approaches alpha stage, more team members are employed and test plans are written. Sometimes features that are not bugs are reported as bugs and sometimes the programming team fails to fix issues first time around. [10]
A tracked item is often called bug, defect, ticket, issue, feature, or for agile software development, story or epic. Items are often categorized by aspects such as severity, priority and version number. In a process sometimes called triage, choices are made for each bug about whether and when to fix it based on information such as the bug's ...
As with all kinds of defensive programming, avoiding bugs is a primary objective; however, the motivation is not as much to reduce the likelihood of failure in normal operation (as if safety were the concern), but to reduce the attack surface – the programmer must assume that the software might be misused actively to reveal bugs, and that ...
Regression testing is performed when changes are made to the existing functionality of the software or if there is a bug fix in the software. Regression testing can be achieved through multiple approaches; if a test all approach is followed, it provides certainty that the changes made to the software have not affected the existing functionalities, which are unaltered.
Infrequently used portions of code, such as document filters or interfaces designed to be used by other programs, may contain bugs that go unnoticed. With changes in user requirements and other external factors, this code may be executed later, thereby exposing the bugs and making the software appear less functional.
Unlike a local game where the inputs of all players are executed instantly in the same simulation or instance of the game, in an online game there are several parallel simulations (one for each player) where the inputs from their respective players are received instantly, while the inputs for the same frame from other players arrive with a certain delay (greater or lesser depending on the ...
