​
Overview

Executes test commands and filters output to show only failures and summary. Supports all major test frameworks with intelligent parsing.

​
Syntax

rtk test <COMMAND...>

​
Arguments

​
COMMAND
string[]
required
Full test command to execute (e.g., cargo test, pytest, npm test)

​
Supported Test Frameworks

​
Rust - Cargo Test

rtk test cargo test
rtk test cargo test --lib
rtk test cargo nextest run
Detects:
  • Test result summary
  • Failed test names
  • Failure details

​
Python - Pytest

rtk test pytest
rtk test pytest -v tests/
Detects:
  • Passed/failed/error counts
  • Failed test names
  • Assertion failures

​
JavaScript - Jest/Vitest

rtk test npm test
rtk test yarn test
rtk test pnpm test
Detects:
  • Test Suites summary
  • Tests summary
  • Failed test names (marked with ✕)

​
Go - Go Test

rtk test go test ./...
rtk test go test -v
Detects:
  • PASS/FAIL lines
  • Failed test output
  • Coverage summary

​
Output Format

​
With Failures

❌ FAILURES:
  FAILED tests::test_addition - assertion failed
  FAILED tests::test_division - panicked at 'divide by zero'
  ... +3 more failures

📊 SUMMARY:
  test result: FAILED. 2 passed; 5 failed; 0 ignored

​
All Passing

📊 SUMMARY:
  test result: ok. 10 passed; 0 failed; 0 ignored

​
With Errors

❌ FAILURES:
  ERROR tests::setup - connection refused
  FAILED tests::test_api - timeout

📊 OUTPUT (last 5 lines):
  Running 12 tests
  ERROR: connection refused
  test result: FAILED

​
Token Savings

90% reduction - only failures and summary shown 
rtk test cargo test
# Shows only failed tests + summary

​
Behavior Details

​
Failure Detection

RTK detects failures via multiple patterns:
  • Lines containing FAILED, ERROR, FAIL
  • Lines containing ✕, ✗, ❌
  • Assertion failures and panic messages
  • Test framework-specific markers

​
Summary Extraction

Extracts key summary lines:
  • test result: (Rust)
  • Tests:, Test Suites: (Jest/Vitest)
  • passed, failed, error counts (Pytest)
  • ok, FAIL lines (Go)

​
Fallback Behavior

If no framework-specific patterns match:
  • Shows last 5 lines of output
  • Preserves exit code
  • Still provides token reduction

​
Tee Output Recovery

On failure (exit code ≠ 0), RTK automatically saves full output and prints a hint: 
❌ FAILURES:
  ...

[full output: ~/.local/share/rtk/tee/test-abc123.txt]
Read the full output without re-running: 
rtk read ~/.local/share/rtk/tee/test-abc123.txt

​
Exit Codes

Preserves the original test command exit code:
  • 0 - All tests passed
  • 1 - Some tests failed
  • 101 - Compilation error (Rust)
  • Other codes preserved as-is
  • rtk cargo test - Rust-specific test filter (90% savings)
  • rtk vitest run - Vitest-specific filter (99.5% savings)
  • rtk playwright test - Playwright-specific filter (94% savings)
  • rtk pytest - Pytest-specific filter (90% savings)
  • rtk err - Show only errors from any command
