The element I got is <div class="x-tool x-box-item" id="tool-123" src="data:image/gif;base64" class="new-img x-tool-maximize".
I particularly need this class="new-img x-tool-maximize"
because its the common of all the screen.
I already tried
driver.findElement(By.className("new-img.x-tool-maximize")).click()
and
driver.findElement(By.className("new-img x-tool-maximize")).click();
and
driver.findElement(By.xpath("//div[contains(@class, 'value') and contains(@class, 'test')]"))``;
