Test versions are builds usually designated with the prefix RC, for Release Candidate, TESTx, for TEST (x = number), or by Version Numberx (where x = version number).
There are usually a TON of these before 3DGE hits a stable (and final) release. Early TEST versions are usually incompatible with STABLE releases, including savegames. Some are from different codebases altogether.
Stable releases are usually the last in lineage (for instance, 1.36A-F, with F being "Final" and thus reaching "Stable"). These are the ones that are guaranteed to work as intended.
note: This article assumes releases in order: DosDOOM, EDGE, and finally 3DGE.
