Cargo Startup Validation

Name: Cargo Startup Validation
Rating: 76
Author: m1nuzz

Purpose

Validates that cargo run starts successfully without runtime errors for long-running applications (daemons, tray apps, servers).

Workflow

1. Run Unit Tests

bash

cargo test --quiet

2. Check Compilation

bash

cargo check --quiet

3. Validate Binary Startup (Critical)

For long-running applications on Windows, run this command directly in the console:

powershell

Start-Process -FilePath "cargo" -ArgumentList "run" -RedirectStandardError "stderr.log" -RedirectStandardOutput "stdout.log" -PassThru | Wait-Process -Timeout 5 -ErrorAction SilentlyContinue

# If process is still running after timeout, kill it
$process = Get-Process | Where-Object {$_.ProcessName -like "*batrust*"} | Select-Object -First 1
if ($process -and !$process.HasExited) {
    Stop-Process -Id $process.Id -Force
}

# Combine output files
Get-Content stdout.log, stderr.log | Out-File -FilePath startup.log

# Check for errors
$errors = Select-String -Path startup.log -Pattern 'error|failed|panic|could not' -CaseSensitive
if ($errors) {
    Write-Host "❌ Runtime errors detected during startup"
    $errors | ForEach-Object { Write-Host $_ }
    Get-Content startup.log
    exit 1
} else {
    Write-Host "✅ No runtime errors detected during startup"
}

# Clean up temporary files
Remove-Item startup.log, stdout.log, stderr.log -ErrorAction SilentlyContinue

Success Criteria

•✅ Unit tests pass
•✅ Code compiles
•✅ Binary starts without errors in first 5 seconds
•✅ No "Error", "Failed", "Panic", "Could not" in output during startup

Failure Examples

code

Battery read error: Could not retrieve battery information from any feature
Warning: Could not create system tray

These are FAILURES even if exit code is 0.
