lab test; in-house test
Used in computing and technical contexts for tests conducted in a controlled indoor environment, as opposed to field tests.
We plan to conduct a lab test of the new software next week.
The in-house test results were good, but field testing is also necessary.
実地試験 refers to field testing in real-world conditions, contrasting with the controlled indoor setting of 室内実験.
Compound of 室内 (indoor) and 実験 (experiment).
