Load Test — Latency Percentiles by Scenario (CSV)

The percentile table a performance report renders as a chart, with mean, p50, p95, p99 and max for each of the four scenarios. The same numbers appear inside the JSON summary in this group, so a chart built from either source can be diffed against the other.

Scenario
Chart latency percentiles and check them against the JSON summary twin.
Expected result
Every value in this table matches the corresponding scenario entry in load-test-summary.json, and p50 <= p95 <= p99 <= max holds on all four rows.

What is a .csv file?

CSV (Comma-Separated Values) is a plain-text tabular format where rows are lines and fields are separated by commas, with quoting rules for values that contain delimiters, quotes, or newlines. It has no formal type system and depends on encoding and dialect conventions. It is the most portable format for tabular data exchange.

How to use this file

Use an example CSV to test parsers against quoting and embedded-delimiter edge cases, header handling, encoding detection, and import pipelines into databases or spreadsheets.

How to use this file for testing

“Load Test — Latency Percentiles by Scenario (CSV)” is a deterministic Novus Examples fixture for Performance testing, CSV parsing, Conversion testing. Documented size, row-count, duration, and resolution ladders for measuring parser, renderer, converter, and upload performance without relying on private production data.

Documented properties for this file: seed 61200 · 4 rows · 8 columns · LF. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.

Test and coverage reports document their totals (suites, cases, passes, failures, skips, covered lines) in the spec table. Point your CI dashboard, coverage gate, or report converter at the file and assert those counts survive; format twins carry identical numbers so a conversion can be scored exactly.
