Morphology
The meaning 'a rocket used to test design or performance' is directly and transparently derived from combining 'test' (an activity for checking performance) with 'rocket' (a rocket vehicle). This noun-noun compounding pattern is common in English (e.g. 'test flight', 'test vehicle') and cross-linguistically straightforward, so a B1 learner who knows both words would readily infer the MWE meaning.
Etymology
Test rocket comes from the simple idea of a rocket built for a test. Engineers launch these rockets to check the design and parts before they make the final rockets, so it means 'a rocket used for testing'.
