Tabalyst smart sample

{{ doc.output.name }}

{{ doc.output.rows | count }} rows of {{ records | count }} from {{ doc.source.name }}, chosen to cover the cases the plan lists. This page reads the sample report alone; it needs neither the source nor the sample.

1 / What it promises

What this sample is, and is not

    {% for code in doc.statements %}
  • {{ statement_words.get(code, code) }}
    • {% endfor %}

2 / Coverage

What the sample covers of its targets

Scope: the {{ cov.defined | count }} targets of the plan, of which {{ cov.evaluable | count }} could be tested on a row. A target is covered when the sample holds at least one row that shows it.

Targets covered
{{ cov.covered | count }}of {{ cov.evaluable | count }} testable
Weighted coverage
{% if cov.weighted.share is not none %}{{ '%.1f' | format(cov.weighted.share * 100) }}%{% else %}–{% endif %}Rarer and more serious targets weigh more
Mandatory targets
{{ cov.mandatory.covered | count }} / {{ cov.mandatory.defined | count }}Values of an exhaustive catalog and confirmed problems
Rows
{{ sel.rows | count }}{{ sel.by_cover | count }} by cover, {{ sel.by_reserve | count }} ordinary{% if sel.shortfall %}; {{ sel.shortfall | count }} short{% endif %}

By family({{ cov.families | length }})

{% for f in cov.families %}{% endfor %}
FamilyDefinedTestableCoveredWeightedShare
{{ family_words.get(f.family, f.family) }}{{ f.defined | count }}{{ f.evaluable | count }}{{ f.covered | count }}{% if f.weight %}{{ '%.1f' | format(f.weight_covered / f.weight * 100) }}%{% else %}–{% endif %}

3 / Gaps

What the sample does not cover({{ cov.missing_total | count }})

Mandatory targets first, then the heaviest. A gap is never hidden: each has its reason.

{% if cov.missing %}
{% for m in cov.missing %}{% endfor %}
TargetFamilyObligationWeightWhy
{{ m.id }}{{ family_words.get(m.family, m.family) }}{{ m.obligation }}{{ '%.1f' | format(m.weight) }}{{ miss_text(m.reason) }}
{% if cov.missing_total > cov.missing | length %}

Showing the {{ cov.missing | length | count }} heaviest of {{ cov.missing_total | count }}; the JSON lists the status of every target.

{% endif %} {% else %}

Every testable target is covered.

{% endif %}

4 / Verification

Counts the plan knew, checked while reading

For the targets whose rows the plan counted exactly (from the Scan), the reading counted them again.

Agreed
{{ cov.verification.agreed | count }} / {{ cov.verification.checked | count }}{% if cov.verification.disagreed %}{{ cov.verification.disagreed | length | count }} differ: the test and the Scan disagree{% else %}No difference{% endif %}
Candidate pool
{{ sel.pool.peak_bytes | size }}{{ sel.pool.candidate_rows | count }} rows held, {{ sel.pool.refused_rows | count }} refused by the budget
Readings of the source
{{ doc.run.passes.total }}{% if doc.run.passes.scan %}First pass and selection{% else %}Selection only; the stored Scan was current{% endif %}
Duration
{{ doc.run.duration_seconds | seconds }}{{ doc.run.records_read | count }} records read
{% if cov.verification.disagreed %}

Targets that differ

    {% for t in cov.verification.disagreed %}
  • {{ t }}
    • {% endfor %}
{% endif %}

Sample report {{ doc.format }} {{ doc.format_version }} revision {{ doc.format_revision }}, seed {{ doc.request.seed }}, Tabalyst {{ doc.engine.version }}. Plan: {{ doc.plan.targets | length | count }} targets in {{ cov.families | length }} families. The sample CSV keeps the rows in the order of the source.
