drive.spec.ts already isolates itself into a unique, timestamped
tmpFolder for getSasjsRootFolder()/getUploadsFolder(), cleaned up via
afterAll(() => deleteFolder(tmpFolder)). But getFilesFolder() - what
nearly every test in this file actually writes to - resolves through
a separate, unmocked function (getSasjsDriveFolder()/process.driveLoc),
so every run left real files/folders (e.g. 'level1', 'my/path/...')
behind in the shared api/sasjs_root/drive/files, causing later runs
to fail: folder-listing tests saw stale entries, and file-creation
tests got 409 Conflict against files a previous run already created.
Mock getFilesFolder() the same way getUploadsFolder() already is, so
it resolves inside the same isolated tmpFolder and gets cleaned up
by the existing afterAll. Verified by running the suite twice in a
row from a clean slate: both runs pass, and the real sasjs_root/drive
is never touched.
For JS/PY/R, processProgram sets session.state = failed (with
failureReason) itself when the interpreter process exits non-zero,
without throwing. ExecutionController.executeProgram then
unconditionally set session.state = completed right after
processProgram returned, silently overwriting that - so anything
downstream inspecting session.state (e.g. scheduleSessionDestroy's
expiresAfterMins branch) would see a crashed session mis-reported as
successful.
Guard the assignment so a failed state is never overwritten. No
effect on SAS, which sets state independently via its own spawned
process lifecycle.
Added Execution.spec.ts covering both the failure case (state stays
failed) and the success case (state still becomes completed), to
guard against regressing in either direction.
