Problem Description

Starting with v42, Electron binaries are downloaded when electron /path/to/file is first run (#49328).

We currently have no automated tests for this. The installation logic is such an important part of the project.

Proposed Solution

We should have automated tests for downloading and installing the Electron binaries.

Alternatives Considered

Wait for bug reports to come flying our way. 📫
