Can Docsumo extract an empty set?

Docsumo passed this empty-set extraction case. The page said no damage or exceptions were reported, and the extracted table came back with zero rows in both the saved JSON and the Results panel.

The test case

Each test case is judged on its own: Pass, Fail, Not gradable, or Untested. The scenario result above is based on this test case.

Why this result

The document said nothing was reported, and Docsumo still returned the declared table with count 0 rather than inventing rows or dropping it. That matches the empty-set requirement, so this is a pass.

Also observed in this test case

Nested empty output. The saved output used a nested empty array for the table value.

No required option. The table setup exposed no per-table required setting, yet Docsumo still returned the empty table.

Configuration and setup

How this tool was set up for the run and what the test needed in place. Each row is a fact from the run's records; a fact the records do not hold is left out, not guessed.

Software that produced the output
Docsumo
Build or version
Not exposed by the hosted product
Surface
Web app
Set up before the run
The document had to state the set was empty with an unambiguous none this period marker, and the schema had to treat the repeated set as required. Docsumo was run to extract that repeated set from the document.

How this scenario is graded

How we decide Pass, Fail and Not gradable. The same rules apply to every tool tested on this scenario.

How results are decided

Each test case gets one result per tool: Pass, Fail or Not gradable. A test case we haven't run yet shows Untested. There are no partial results.

The rules
  • Pass: the tool did everything the test expected, and nothing it said contradicts the correct answer.
  • Fail: at least one expected behaviour clearly didn't happen; the test case's result says which one and quotes the tool.
  • Not gradable: our evidence couldn't settle the outcome (for example a record we needed is missing). It is never counted as a fail, and the test case's result says what's missing.

Where this sits in the benchmark

This page is one cell of a larger study: one tool, one scenario. Only this benchmark's frame appears here.

History of this result

What has happened to this result since it was first published. Runs and grades are never overwritten: a retest or a re-grade publishes a new result and keeps the earlier one readable.

Act on this result

Nothing filed here edits the run or the grade. A challenge opens a review, and a review can produce a new run or a re-grade — which becomes the current result and leaves this one in the history.

This matches what I see

You run the same kind of test against your own setup and get the same behaviour.
