It is used to determine how much work will be required to solve or work around a software issue. Typically, a "spike test" involves gathering additional information or testing for easily reproduced edge cases. The term is used in agile software development approaches like Scrum or Extreme Programming. Uses. A spike in a sprint can be used in a number of ways: A distinction can be made between technical spikes and functional spikes. The technical spike  is used more often for evaluating the impact new technology has on the current implementation. A functional spike is used to determine the interaction with a new feature or implementation.
