Go Test Formatter

A simple tool to parse and format Go test output with better readability and useful summaries.

Usage

Pipe your Go test output through this tool:

go test -json ./... | go run main.go

Options

• -condense - Show package-level summaries for passing tests instead of individual test lines
• -no-color - Disable colored output
• -top N - Show top N slowest tests (default: 10)
• -show-logs - Include all output logs in failure details
• -github - Emit GitHub Actions ::error annotations

Features

• Color-coded test results (PASS/FAIL/SKIP)
• Package-grouped test organization
• Failed test details with file locations
• Build error reporting
• Slowest test identification
• Summary statistics

Example

# Basic usage
go test -json ./... | go run main.go

# Condensed view with top 5 slowest tests
go test -json ./... | go run main.go -condense -top 5

# No colors (for CI/logging)
go test -json ./... | go run main.go -no-color

The tool reads JSON test events from stdin and outputs a formatted summary to stdout. It exits with code 1 if any tests fail or build errors occur.
