LeanFT 14,5文件上传功能

Question

能否让我知道为什么我的文件上传功能不起作用：

@Test
public void testUploadFile() throws GeneralLeanFtException {        
    //Launch Chrome
    Browser browser = BrowserFactory.launch(BrowserType.CHROME);        
    browser.navigate("https://uploadfiles.io/");        
    //This is NOT getting invoked while running
    browser.describe(WebElement.class, new WebElementDescription.Builder()
           .innerText("Drop file here or click to upload. (5GB max) ").tagName("FORM").build()).click();                
}

我该怎么办？
