Testing in Agile

You are defining the test approach for an Agile project that is developing a system to control traffic lights at busy road junctions, using inputs from sensors that measure traffic density and flow rates on the roads approaching the junctions. It is a safety-critical application, but because of the project team’s skill and experience, a risk assessment has determined that its risk level is low.

Which option in the table below represents the BEST test approach for this release?

Key to symbols:

++ (highly recommended)

  • (recommended)

o (neutral / optional)

  • (not recommended)

-- (not to be used)

Explanation

For a low-risk safety-critical system, automated testing, exploratory testing, and specification-based/manual black-box testing are all recommended. Automation remains recommended for safety-critical systems regardless of the risk level, while the lower assessed risk does not require any of these approaches to be highly recommended.
