# Tests

- Place a line with "// SUT" before the line that causes the code being tested to be exercised.

Can we add conditions and/or caveats to this? A lot of tests are simple enough that this would just be noise. Right now we have 168 instances of ``// SUTin*.ts` files, and 2,745 instances of `it(`. I'm sure some could use it that lack it, but I'm not sure a 16-fold increase in usage is called for.

  /** Whether to show a caution notice about comparing older durations. */
  get shouldShowDurationComparisonCaution(): boolean {

As a nit about naming, I think should is mostly redundant. That said, I do appreciate erring on the side of calrity, and not choosing a name like isDurationComparisonCuationShown.

    // Day after the date when draftGenerationRequestId began to be used, which was in SFv5.46.1 at
    // 2025-12-18T17:48:57Z.
    const requestIdIntroductionDate: Date = new Date(2025, 12 - 1, 18 + 1);

This would be way simpler as new Date(2025-12-18) (or you could use an exact timestamp) since everyone is more familiar with ISO date formats than JavaScript date APIs. Additionally, it's interpreted as UTC, whereas constructing a date from numbers results in it being interpreted as local time, meaning the cutoff depends on the user's timezone.

(Also in tests)

src/SIL.XForge.Scripture/ClientApp/src/app/serval-administration/draft-jobs.component.ts line 222 at r1 (raw file):

    const rangeStartMs: number = this.currentDateRange.start.getTime();
    const cutoffMs: number = requestIdIntroductionDate.getTime();

For what it's worth, you can directly compare JavaScript datetimes (and if you couldn't, TypeScript would yell at you for trying to compare incompatible types).
