ConsoleMessage objects are dispatched by page via the Page.onConsoleMessage(handler) event. For each console messages logged in the page there will be corresponding event in the Playwright context.

// Listen for all System.out.printlns
page.onConsoleMessage(msg -> System.out.println(msg.text()));

// Listen for all console events and handle errors
page.onConsoleMessage(msg -> {
if ("error".equals(msg.type()))
System.out.println("Error text: " + msg.text());

// Get the next System.out.println
ConsoleMessage msg = page.waitForConsoleMessage(() -> {
// Issue console.log inside the page
page.evaluate("console.log('hello', 42, { foo: 'bar' });");

// Deconstruct console.log arguments
msg.args().get(0).jsonValue() // hello
msg.args().get(1).jsonValue() // 42
