Working with windows and tabs
Janelas e guias
Pegue o idenficador da janela
O WebDriver não faz distinção entre janelas e guias. E se seu site abre uma nova guia ou janela, o Selenium permitirá que você trabalhe usando um identificador. Cada janela tem um identificador único que permanece persistente em uma única sessão. Você pode pegar o identificador atual usando:
driver.getWindowHandle();
driver.current_window_handle
driver.CurrentWindowHandle;
driver.window_handle
await driver.getWindowHandle();
driver.windowHandle
Alternando janelas ou guias
Clicar em um link que abre em uma nova janela focará a nova janela ou guia na tela, mas o WebDriver não saberá qual janela que o sistema operacional considera ativa. Para trabalhar com a nova janela você precisará mudar para ela. Se você tiver apenas duas guias ou janelas abertas, e você sabe com qual janela você iniciou, pelo processo de eliminação você pode percorrer as janelas ou guias que o WebDriver pode ver e alternar para aquela que não é o original.
No entanto, o Selenium 4 fornece uma nova API NewWindow que cria uma nova guia (ou) nova janela e muda automaticamente para ela.

Criar nova janela (ou) nova guia e alternar
Cria uma nova janela (ou) guia e focará a nova janela ou guia na tela. Você não precisa mudar para trabalhar com a nova janela (ou) guia. Se você tiver mais de duas janelas (ou) guias abertas diferentes da nova janela, você pode percorrer as janelas ou guias que o WebDriver pode ver e mudar para aquela que não é a original.
Nota: este recurso funciona com Selenium 4 e versões posteriores.
// Opens a new tab and switches to new tab
driver.switchTo().newWindow(WindowType.TAB);
// Opens a new window and switches to new window
driver.switchTo().newWindow(WindowType.WINDOW);
# Opens a new tab and switches to new tab
driver.switch_to.new_window('tab')
# Opens a new window and switches to new window
driver.switch_to.new_window('window')
// Opens a new tab and switches to new tab
driver.SwitchTo().NewWindow(WindowType.Tab)
// Opens a new window and switches to new window
driver.SwitchTo().NewWindow(WindowType.Window)
# Note: The new_window in ruby only opens a new tab (or) Window and will not switch automatically
# The user has to switch to new tab (or) new window
# Opens a new tab and switches to new tab
driver.manage.new_window(:tab)
# Opens a new window and switches to new window
driver.manage.new_window(:window)
// Opens a new tab and switches to new tab
await driver.switchTo().newWindow('tab');
// Opens a new window and switches to new window
await driver.switchTo().newWindow('window');
// Opens a new tab and switches to new tab
driver.switchTo().newWindow(WindowType.TAB)
// Opens a new window and switches to new window
driver.switchTo().newWindow(WindowType.WINDOW)
Fechando uma janela ou guia
Quando você fechar uma janela ou guia e que não é a última janela ou guia aberta em seu navegador, você deve fechá-la e alternar de volta para a janela que você estava usando anteriormente. Supondo que você seguiu a amostra de código na seção anterior, você terá o identificador da janela anterior armazenado em uma variável. Junte isso e você obterá:
//Close the tab or window
driver.close();
//Switch back to the old tab or window
driver.switchTo().window(originalWindow);
#Close the tab or window
driver.close()
#Switch back to the old tab or window
driver.switch_to.window(original_window)
//Close the tab or window
driver.Close();
//Switch back to the old tab or window
driver.SwitchTo().Window(originalWindow);
#Close the tab or window
driver.close
#Switch back to the old tab or window
driver.switch_to.window original_window
//Close the tab or window
await driver.close();
//Switch back to the old tab or window
await driver.switchTo().window(originalWindow);
//Close the tab or window
driver.close()
//Switch back to the old tab or window
driver.switchTo().window(originalWindow)
Esquecer de voltar para outro gerenciador de janela após fechar uma janela deixará o WebDriver em execução na página agora fechada e acionara uma No Such Window Exception. Você deve trocar de volta para um identificador de janela válido para continuar a execução.
Sair do navegador no final de uma sessão
Quando você terminar a sessão do navegador, você deve chamar a função quit(), em vez de fechar:
driver.quit();
driver.quit()
driver.Quit();
driver.quit
await driver.quit();
driver.quit()
- quit() irá:
- Fechar todas as janelas e guias associadas a essa sessão do WebDriver
- Fechar o processo do navegador
- Fechar o processo do driver em segundo plano
- Notificar o Selenium Grid de que o navegador não está mais em uso para que possa ser usado por outra sessão (se você estiver usando Selenium Grid)
A falha em encerrar deixará processos e portas extras em segundo plano rodando em sua máquina, o que pode causar problemas mais tarde.
Algumas estruturas de teste oferecem métodos e anotações em que você pode ligar para derrubar no final de um teste.

Se não estiver executando o WebDriver em um contexto de teste, você pode considerar o uso do
try/finally
que é oferecido pela maioria das linguagens para que uma exceção
ainda limpe a sessão do WebDriver.
try {
//WebDriver code here...
} finally {
driver.quit();
}
try:
#WebDriver code here...
finally:
driver.quit()
try {
//WebDriver code here...
} finally {
driver.Quit();
}
begin
#WebDriver code here...
ensure
driver.quit
end
try {
//WebDriver code here...
} finally {
await driver.quit();
}
try {
//WebDriver code here...
} finally {
driver.quit()
}
O WebDriver do Python agora suporta o gerenciador de contexto python,
que ao usar a palavra-chave with
pode encerrar automaticamente o
driver no fim da execução.
with webdriver.Firefox() as driver:
# WebDriver code here...
# WebDriver will automatically quit after indentation
Gerenciamento de janelas
A resolução da tela pode impactar como seu aplicativo da web é renderizado, então WebDriver fornece mecanismos para mover e redimensionar a janela do navegador.
Coletar o tamanho da janela
Obtém o tamanho da janela do navegador em pixels.
//Access each dimension individually
int width = driver.manage().window().getSize().getWidth();
int height = driver.manage().window().getSize().getHeight();
//Or store the dimensions and query them later
Dimension size = driver.manage().window().getSize();
int width1 = size.getWidth();
int height1 = size.getHeight();
# Access each dimension individually
width = driver.get_window_size().get("width")
height = driver.get_window_size().get("height")
# Or store the dimensions and query them later
size = driver.get_window_size()
width1 = size.get("width")
height1 = size.get("height")
//Access each dimension individually
int width = driver.Manage().Window.Size.Width;
int height = driver.Manage().Window.Size.Height;
//Or store the dimensions and query them later
System.Drawing.Size size = driver.Manage().Window.Size;
int width1 = size.Width;
int height1 = size.Height;
# Access each dimension individually
width = driver.manage.window.size.width
height = driver.manage.window.size.height
# Or store the dimensions and query them later
size = driver.manage.window.size
width1 = size.width
height1 = size.height
// Access each dimension individually
const { width, height } = await driver.manage().window().getRect();
// Or store the dimensions and query them later
const rect = await driver.manage().window().getRect();
const width1 = rect.width;
const height1 = rect.height;
//Access each dimension individually
val width = driver.manage().window().size.width
val height = driver.manage().window().size.height
//Or store the dimensions and query them later
val size = driver.manage().window().size
val width1 = size.width
val height1 = size.height
Definir o tamanho da janela
Restaura a janela e define o tamanho da janela.
driver.manage().window().setSize(new Dimension(1024, 768));
driver.set_window_size(1024, 768)
driver.Manage().Window.Size = new Size(1024, 768);
driver.manage.window.resize_to(1024,768)
await driver.manage().window().setRect({ width: 1024, height: 768 });
driver.manage().window().size = Dimension(1024, 768)
Coletar posição da janela
Busca as coordenadas da coordenada superior esquerda da janela do navegador.
// Access each dimension individually
int x = driver.manage().window().getPosition().getX();
int y = driver.manage().window().getPosition().getY();
// Or store the dimensions and query them later
Point position = driver.manage().window().getPosition();
int x1 = position.getX();
int y1 = position.getY();
# Access each dimension individually
x = driver.get_window_position().get('x')
y = driver.get_window_position().get('y')
# Or store the dimensions and query them later
position = driver.get_window_position()
x1 = position.get('x')
y1 = position.get('y')
//Access each dimension individually
int x = driver.Manage().Window.Position.X;
int y = driver.Manage().Window.Position.Y;
//Or store the dimensions and query them later
Point position = driver.Manage().Window.Position;
int x1 = position.X;
int y1 = position.Y;
#Access each dimension individually
x = driver.manage.window.position.x
y = driver.manage.window.position.y
# Or store the dimensions and query them later
rect = driver.manage.window.rect
x1 = rect.x
y1 = rect.y
// Access each dimension individually
const { x, y } = await driver.manage().window().getRect();
// Or store the dimensions and query them later
const rect = await driver.manage().window().getRect();
const x1 = rect.x;
const y1 = rect.y;
// Access each dimension individually
val x = driver.manage().window().position.x
val y = driver.manage().window().position.y
// Or store the dimensions and query them later
val position = driver.manage().window().position
val x1 = position.x
val y1 = position.y
Definir posição da janela
Move a janela para a posição escolhida.
// Move the window to the top left of the primary monitor
driver.manage().window().setPosition(new Point(0, 0));
# Move the window to the top left of the primary monitor
driver.set_window_position(0, 0)
// Move the window to the top left of the primary monitor
driver.Manage().Window.Position = new Point(0, 0);
driver.manage.window.move_to(0,0)
// Move the window to the top left of the primary monitor
await driver.manage().window().setRect({ x: 0, y: 0 });
// Move the window to the top left of the primary monitor
driver.manage().window().position = Point(0,0)
Maximizar janela
Aumenta a janela. Para a maioria dos sistemas operacionais, a janela irá preencher a tela, sem bloquear os próprios menus do sistema operacional e barras de ferramentas.
driver.manage().window().maximize();
driver.maximize_window()
driver.Manage().Window.Maximize();
driver.manage.window.maximize
await driver.manage().window().maximize();
driver.manage().window().maximize()
Minimizar janela
Minimiza a janela do contexto de navegação atual. O comportamento exato deste comando é específico para gerenciadores de janela individuais.
Minimizar Janela normalmente oculta a janela na bandeja do sistema.
Nota: este recurso funciona com Selenium 4 e versões posteriores.
driver.manage().window().minimize();
driver.minimize_window()
driver.Manage().Window.Minimize();
driver.manage.window.minimize
await driver.manage().window().minimize();
driver.manage().window().minimize()
Janela em tamanho cheio
Preenche a tela inteira, semelhante a pressionar F11 na maioria dos navegadores.
driver.manage().window().fullscreen();
driver.fullscreen_window()
driver.Manage().Window.FullScreen();
driver.manage.window.full_screen
await driver.manage().window().fullscreen();
driver.manage().window().fullscreen()
TakeScreenshot
