Gap analysis — c11 in decision #174
scry-mcdc · lib.rs:776 · branch 1553
Status: GAP
What you need
To prove condition c11 independently affects the decision, you need a row where c11 = T and the outcome differs from row 515 (where c11 = F).
Required condition vector:
c0 = T c1 = F c2 = F c3 = F c4 = T c5 = F c6 = F c7 = F c8 = * c9 = T c10 = F c11 = T
Conditions marked * were short-circuited in the baseline row; the new test must drive inputs so they get evaluated to either T or F.
Suggested test stub
#[test]
fn closes_gap_d174_c11() {
// Verdict: scry-mcdc
// Source: lib.rs:776
// Branch: 1553
//
// TODO: drive the function so condition c11 evaluates to the
// value above and the resulting decision outcome differs from
// the existing pair row.
todo!("witness viz: gap drill-down for d#174/c11");
}
After adding the test, re-run: witness instrument && witness run --invoke run_row_NEW && witness report. The condition should flip from gap to proved.
