        // 3. 找到网页上name属性为"my-text"的元素textBox
        WebElement textBox = driver.findElement(By.name("my-text"));
        // 3.1 设置textBox的值为Selenium
        textBox.sendKeys("Test selenium");

//        sleep(2000);
        // 4. 点击提交元素

//        sleep(2000);
        // 5. 断言页面名称为"Web form - target page"
        assertEquals("Web form - target page", driver.getTitle());

//        sleep(2000);
        // 6. 找到id为"message"的消息，断言为"Received!"
        WebElement message = driver.findElement(By.id("message"));
        assertEquals("Received!", message.getText());

    @Test
    public void simpleSeleniumTest() {
        new SimpleSelenium(driver)
                .openWeb()

                .fillForm()

    }

    @AfterEach
    public void teardown() {
        driver.quit();
    }

    public void sleep(long timeMillis) {
        try {
            Thread.sleep(timeMillis);
        } catch (InterruptedException e) {
            throw new RuntimeException(e);
        }
    }
}

3. 效果

运行测试后，会先等待1~5秒（具体看机器性能），打开一个谷歌游览器，在输入网址，进入网页，并找到网页中的元素，输入内容后，点击提交按钮，网页会自动跳转到新的页面。结束
