This section contains the APIs related to logging.

Console logs

Listen to the console.log events and register callbacks to process the event.

Selenium v4.8

    public void jsErrors() {
        CopyOnWriteArrayList<ConsoleLogEntry> logs = new CopyOnWriteArrayList<>();

        try (LogInspector logInspector = new LogInspector(driver)) {
            logInspector.onConsoleEntry(logs::add);
        }

        driver.get("https://www.selenium.dev/selenium/web/bidi/logEntryAdded.html");

            await driver.findElement({id: 'consoleLog'}).click()

            assert.equal(logEntry.text, 'Hello, world!')
            assert.equal(logEntry.realm, null)
            assert.equal(logEntry.type, 'console')
            assert.equal(logEntry.level, 'info')
            assert.equal(logEntry.method, 'log')
            assert.equal(logEntry.stackTrace, null)
            assert.equal(logEntry.args.length, 1)

JavaScript exceptions

Listen to the JS Exceptions and register callbacks to process the exception details.

            logInspector.onJavaScriptLog(future::complete);

            driver.get("https://www.selenium.dev/selenium/web/bidi/logEntryAdded.html");
            driver.findElement(By.id("jsException")).click();

            JavascriptLogEntry logEntry = future.get(5, TimeUnit.SECONDS);

            Assertions.assertEquals("Error: Not working", logEntry.getText());

            const inspector = await LogInspector(driver)
            await inspector.onJavascriptException(function (log) {
                logEntry = log
            })

            await driver.get('https://www.selenium.dev/selenium/web/bidi/logEntryAdded.html')
            await driver.findElement({id: 'jsException'}).click()

            assert.equal(logEntry.text, 'Error: Not working')
            assert.equal(logEntry.type, 'javascript')
            assert.equal(logEntry.level, 'error')

Listen to all JS logs at all levels and register callbacks to process the log.

Selenium v4.8

            driver.findElement(By.id("consoleLog")).click();

            ConsoleLogEntry logEntry = future.get(5, TimeUnit.SECONDS);

            Assertions.assertEquals("Hello, world!", logEntry.getText());
            Assertions.assertNull(logEntry.getRealm());
            Assertions.assertEquals(1, logEntry.getArgs().size());
            Assertions.assertEquals("console", logEntry.getType());
