Testdriver:Focus Application

Overview

Move a specific application window to the front. Make it the active window for interactions.

Syntax

javascriptCopy code
await testdriver.focusApplication(name)

Parameters

Returns

Promise<string> - The result message

Examples

Common Applications

javascriptCopy code
// 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

javascriptCopy code
// 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

Always focus the target application before interacting with its UI:

javascriptCopy code
await testdriver.focusApplication('Google Chrome');

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

Give applications time to open before focusing:

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

javascriptCopy code
// ✅ Correct
await testdriver.focusApplication('Google Chrome');

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

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

Use Cases

Copy code
await testdriver.focusApplication('Notepad');
await testdriver.type(data);
await testdriver.pressKeys(['ctrl', 's']);

await testdriver.focusApplication('Google Chrome');
const nextButton = await testdriver.find('next button');
await nextButton.click();
```

Copy code
await testdriver.focusApplication('Microsoft Edge');
await testdriver.assert('page loaded correctly in Edge');
```

Copy code
await testdriver.focusApplication('Notepad');
await testdriver.type('Test content');
```

Copy code
// Click desktop icon
const icon = await testdriver.find('Chrome icon on desktop');
await icon.click();

await new Promise(r => setTimeout(r, 2000));

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