Overview

Bring a specific application window to the foreground and make it the active window for interactions.

await testdriver.focusApplication(name)

Parameters

<ParamField path="name" type="string" required>

Application name (e.g., 'Google Chrome', 'Microsoft Edge', 'Notepad')

</ParamField>

Returns

Promise<string> - Result message

Examples

Common Applications

// Focus Chrome browser
await testdriver.focusApplication('Google Chrome');

// Focus Edge browser
await testdriver.focusApplication('Microsoft Edge');

// Focus Notepad
await testdriver.focusApplication('Notepad');

// Focus File Explorer
await testdriver.focusApplication('File Explorer');

// Focus Visual Studio Code
await testdriver.focusApplication('Visual Studio Code');

After Opening Applications

// Open Chrome and focus it
await testdriver.exec('pwsh', `
  Start-Process "C:/Program Files/Google/Chrome/Application/chrome.exe" -ArgumentList "https://example.com"
`, 5000);

await new Promise(r => setTimeout(r, 2000)); // Wait for launch

// Focus the Chrome window
await testdriver.focusApplication('Google Chrome');

Best Practices

<Check>

Focus before UI interactions

Always focus the target application before interacting with its UI:

  await testdriver.focusApplication('Google Chrome');
  
  const button = await testdriver.find('submit button');
  await button.click();

</Check>

<Check>

Wait after launching apps

Give applications time to open before focusing:

  await testdriver.exec('pwsh', 'Start-Process notepad', 5000);
  await new Promise(r => setTimeout(r, 1000)); // Wait for launch
  await testdriver.focusApplication('Notepad');

</Check>

<Check>

Use exact application names

  // ✅ Correct
  await testdriver.focusApplication('Google Chrome');
  
  // ❌ May not work
  await testdriver.focusApplication('Chrome');
  await testdriver.focusApplication('chrome.exe');

</Check>

<Warning>

Application must be running

The application must already be running. focusApplication() won't launch applications, only bring existing windows to the foreground.

</Warning>
