WHAT’S CONTEXT-DRIVEN TESTING?
16Context-Driven Testing in Agile
Context-driven testing is a model for developing and debugging computer software that takes into
account the ways in which the programs will be used or are expected to be used in the real world.
Tech Target
Context-driven testing is a certain type of software testing that considers the product’s use in the
field, or a performance or production environment. It is one way that developers assess software as it
is built, looking for flaws and otherwise optimizing its design before its eventual final release
