The phrase "a vacuum test" is correct and usable in written English.
It can be used in contexts related to engineering, manufacturing, or scientific testing where a vacuum is created to assess the integrity or performance of a system or component.
Example: "Before finalizing the design, we need to conduct a vacuum test to ensure there are no leaks in the system."
Alternatives: "vacuum assessment" or "vacuum evaluation".
