Testing and Code Review | Dataford Interview Questions

Tell me about a time you wrote code, added tests, and used a code review process to improve quality.

As the coding portion, implement a validator for a sequence of development actions. Return True when the sequence contains write, followed later by test, followed later by review; otherwise return False. Repeated actions and unrelated action names may appear, and only the first valid occurrence of each required stage matters.

Function signature: def validate_quality_workflow(actions):, where actions is a list of strings and the result is a Boolean.

Constraints

0 <= len(actions) <= 10^5
Each action is a string
The required stages are exactly "write", "test", and "review"
Unrecognized action names may appear

Function Signature

def validate_quality_workflow(actions):
