Shell Execution (Linux)

Run shell commands in the Linux sandbox.

Basic Commands

javascriptCopy code
// List files
const files = await testdriver.exec('sh', 'ls -la', 5000);

// Check current directory
const pwd = await testdriver.exec('sh', 'pwd', 5000);

// Run a script
await testdriver.exec('sh', './setup.sh', 60000);

File Operations

javascriptCopy code

await testdriver.exec('sh', 'echo "Hello World" > test.txt', 5000);

// Read a file
const content = await testdriver.exec('sh', 'cat test.txt', 5000);

// Copy files
await testdriver.exec('sh', 'cp source.txt dest.txt', 5000);

// Delete files
await testdriver.exec('sh', 'rm test.txt', 5000);

PowerShell Execution (Windows)

Execute PowerShell commands in the Windows sandbox.

Software Installation

javascriptCopy code
// Install npm package globally
await testdriver.exec('pwsh', 'npm install -g http-server', 30000);

// Install via Chocolatey
await testdriver.exec('pwsh', 'choco install firefox -y', 60000);

// Download and run installer
await testdriver.exec('pwsh', `
  Invoke-WebRequest -Uri "https://example.com/setup.exe" -OutFile "C:\\setup.exe"
  Start-Process -FilePath "C:\\setup.exe" -ArgumentList "/S" -Wait
`, 120000);

File Operations

javascriptCopy code
// Create a file
await testdriver.exec('pwsh', `
  Set-Content -Path "C:\\test.txt" -Value "Hello World"
`, 5000);

// Read a file
const content = await testdriver.exec('pwsh', 
  'Get-Content -Path "C:\\test.txt"', 
  5000
);

// Copy files
await testdriver.exec('pwsh', 
  'Copy-Item -Path "C:\\source.txt" -Destination "C:\\dest.txt"', 
  5000
);

// Delete files
await testdriver.exec('pwsh', 
  'Remove-Item -Path "C:\\test.txt"', 
  5000
);

// List directory
const files = await testdriver.exec('pwsh', 
  'Get-ChildItem -Path "C:\\Users\\testdriver\\Documents"', 
  5000
);

Process Management

javascriptCopy code
// List running processes
const processes = await testdriver.exec('pwsh', 'Get-Process', 5000);

// Start application
await testdriver.exec('pwsh', `
  Start-Process "C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe" -ArgumentList "--start-maximized", "https://example.com"
`, 5000);

// Kill a process
await testdriver.exec('pwsh', 'Stop-Process -Name "chrome" -Force', 5000);

// Wait for process
await testdriver.exec('pwsh', 'Start-Process notepad -Wait', 30000);

Environment Variables

javascriptCopy code
// Set environment variable (session)
await testdriver.exec('pwsh', '$env:MY_VAR = "value"', 5000);

// Get environment variable
const value = await testdriver.exec('pwsh', '$env:MY_VAR', 5000);

// Set persistent environment variable
await testdriver.exec('pwsh', `
  [Environment]::SetEnvironmentVariable("MY_VAR", "value", "User")
`, 5000);

Network Operations

javascriptCopy code
// Test connectivity
const pingResult = await testdriver.exec('pwsh', 
  'Test-NetConnection google.com', 
  10000
);

// Download file
await testdriver.exec('pwsh', `
  Invoke-WebRequest -Uri "https://example.com/file.zip" -OutFile "C:\\Downloads\\file.zip"
`, 30000);

// Check if port is open
const portOpen = await testdriver.exec('pwsh', 
  'Test-NetConnection -ComputerName localhost -Port 3000', 
  5000
);

Silent Execution

Suppress output for background operations:

javascriptCopy code
// Silent installation
await testdriver.exec('pwsh', 'npm install -g some-package', 30000, true);

// Start background process
await testdriver.exec('pwsh', 'Start-Process notepad', 5000, true);

// Run setup script silently
await testdriver.exec('pwsh', '.\\setup.ps1', 60000, true);

Best Practices

javascriptCopy code
// Quick operations: 5000ms
await testdriver.exec('sh', 'ls -la', 5000);

// Installations: 30000-60000ms
await testdriver.exec('pwsh', 'npm install -g package', 30000);

// Downloads or complex operations: 60000-120000ms
await testdriver.exec('pwsh', 'Install-Module Something', 120000);

javascriptCopy code
try {
  await testdriver.exec('pwsh', 'Some-Command', 5000);
} catch (error) {
  console.error('Command failed:', error.message);
  // Fallback or retry logic
}

javascriptCopy code
// Silent install
await testdriver.exec('pwsh', 'npm install -g tool', 30000, true);

// Background service
await testdriver.exec('pwsh', 'Start-Service MyService', 5000, true);

Use proper escaping for special characters:

javascriptCopy code
// Use backticks for newlines
await testdriver.exec('pwsh', `
  Write-Host "Line 1\`nLine 2"
`, 5000);

// Use single quotes to avoid variable expansion
await testdriver.exec('pwsh', 
  "Write-Host 'Text with $special chars'", 
  5000
);
