Test statistics plugin for InvenTree

InvenTree Test Statistics Plugin

An InvenTree plugin for generating and viewing statistical test data.

Description

The Test Statistics plugin provides a panel for viewing statistical test data aggregated by test template. It displays pass/fail counts and percentages, supports date range filtering, and shows month-by-month breakdowns as bar charts.

Test statistics can be generated for a particular part, or for a selected build order.

Test for a part (including variants)

Features

Panel Interface

The statistics panel provides:

• Date range selector — Filter results by month using start and end date pickers. Defaults to the past year.
• Include Variants toggle — Optionally include test results from variant parts in the statistics.
• Results table — Each row represents a single (enabled) test template and shows:
  • Test name and description
  • Total pass and fail counts, each with percentage of total runs
  • Total number of test executions
• Monthly breakdown — Click to expand any row and view a stacked bar chart of pass/fail counts broken down month by month across the selected date range.

API

The plugin exposes a REST endpoint at plugin/test_statistics/statistics/ that accepts the following query parameters:

Parameter	Type	Description
part	integer	Filter by Part (primary key)
include_variants	boolean	Include variant parts in results (default: false)
build	integer	Filter by Build Order (primary key)
stock_item	integer	Filter by Stock Item (primary key)
date_after	date	Include results on or after this date
date_before	date	Include results on or before this date
started_after	datetime	Include results where test started on or after this datetime
started_before	datetime	Include results where test started on or before this datetime
finished_after	datetime	Include results where test finished on or after this datetime
finished_before	datetime	Include results where test finished on or before this datetime

Only test templates with enabled=True are included in the response.

The endpoint returns a list of objects, one per test template:
