From 406c3bcc82995830d5306e6a6f97abcf724d48b8 Mon Sep 17 00:00:00 2001 From: Felipe Cardoso Date: Sun, 2 Nov 2025 05:27:24 +0100 Subject: [PATCH] Update coverage report with resolved tracking issue and 88% overall coverage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Resolved `pytest-cov` tracking for async routes by adjusting `.coveragerc` to include `greenlet` concurrency. Coverage improved from 79% to 88%, with significant gains across key modules like `admin.py` (46% → 98%). Updated details on coverage gaps and priorities for reaching 95% target. --- backend/docs/COVERAGE_REPORT.md | 238 ++++++++++++++++++++++---------- 1 file changed, 163 insertions(+), 75 deletions(-) diff --git a/backend/docs/COVERAGE_REPORT.md b/backend/docs/COVERAGE_REPORT.md index c159360..3ee68b5 100644 --- a/backend/docs/COVERAGE_REPORT.md +++ b/backend/docs/COVERAGE_REPORT.md @@ -1,56 +1,96 @@ # Test Coverage Analysis Report -**Date**: 2025-11-01 -**Current Coverage**: 79% (1,932/2,439 lines) +**Date**: 2025-11-02 (Updated) +**Current Coverage**: 88% (2,157/2,455 lines) +**Previous Coverage**: 79% (1,932/2,439 lines) **Target Coverage**: 95% -**Gap**: 270 lines needed to reach 90%, ~390 lines for 95% +**Gap**: ~175 lines needed to reach 95% ## Executive Summary -This report documents the current state of test coverage, identified issues with coverage tracking, and actionable paths to reach the 95% coverage target. +This report documents the **successful resolution** of the coverage tracking issue and the path to reach the 95% coverage target. ### Current Status -- **Total Tests**: 596 passing -- **Overall Coverage**: 79% -- **Lines Covered**: 1,932 / 2,439 -- **Lines Missing**: 507 +- **Total Tests**: 598 passing ✅ +- **Overall Coverage**: 88% (up from 79%) +- **Lines Covered**: 2,157 / 2,455 +- **Lines Missing**: 298 (down from 507) +- **Improvement**: +9 percentage points (+225 lines covered) -### Key Finding: Coverage Tracking Issue +### ✅ RESOLVED: Coverage Tracking Issue -**Critical Issue Identified**: Pytest-cov is not properly recording coverage for FastAPI route files when tests are executed, despite: -1.
