Atomic Talk Title: Ichhadhari Data: The ReVoLT Mnemonic

The usual view of a variable and a value is of very little use when a tester has to think in terms of test design and sampling. A tester typically deals with what I call a Wanderer – data that goes through transformations and wanders through a system and outside it. In the process, the variables can only be imagined, many don’t technically exist and are imaginary. Along with it, the 4 dimensions of data, namely Representation, Value, Length and Type are fluent. This talk is an introductory view of my mental model of this Wanderer.

Talk Takeaways

  • An unconventional look at variables and data
  • A Pluralistic way of data in the context of black and white box testing
  • Some pertinent questions about the established test design techinques
