Test cases generated from requirements
What this task is
Designing test cases from requirement documents: listing the steps, input data and expected results needed to cover both the normal flow and the error scenarios of each feature.
How AI replaces it
Since 2023, large language models can read requirement documents or user stories and generate structured test cases in bulk, flagging boundary conditions. By around 2027, most routine test cases are expected to be AI-written.
What stays human
QA engineers check that generated cases reflect real business risks, add the scenarios AI tends to miss, and decide where limited testing effort should focus.
