如何设置Firefox在Katalon测试执行期间无需提示即可下载文件？

我试图创建一个非常简单的Katalon测试用例，打开Firefox，转到给定的URL并单击按钮下载文件。我已经根据Katalon文档（）设置了所需的功能，但运气不佳。当我尝试下载文件时，会出现一个文件提示，但文件未下载。如何禁用提示并立即下载文件

下面是软件版本、源代码和屏幕截图

Windows 10、Katalon Studio 7.2.1、Mozilla Firefox 72.0.2、Selenium 3.141.59

WebUI.click(findTestObject('downloadCsvFileButton'))

对于Chrome，项目设置中所需功能的默认设置可以正常工作，但对于Firefox，我必须做一些变通来使其正常工作

因此，我找到了这个主题，@kazurayam的回复帮助我创建了一个脚本，用于初始化WebDriver，我在每个测试用例之前调用它：

import org.openqa.selenium.WebDriver
import org.openqa.selenium.firefox.FirefoxDriver
import org.openqa.selenium.firefox.FirefoxOptions
import org.openqa.selenium.firefox.FirefoxProfile
import org.openqa.selenium.firefox.ProfilesIni
import static com.kms.katalon.core.testobject.ObjectRepository.findTestObject
import com.kms.katalon.core.webui.driver.DriverFactory
import com.kms.katalon.core.webui.driver.WebUIDriverType
import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI
import internal.GlobalVariable as GlobalVariable

WebUIDriverType executedBrowser = DriverFactory.getExecutedBrowser()
switch(executedBrowser) {
    case WebUIDriverType.FIREFOX_DRIVER:          // "Firefox"
        System.setProperty('webdriver.gecko.driver', DriverFactory.getGeckoDriverPath())
        FirefoxOptions options = new FirefoxOptions()

        options.addPreference('marionette', true)
        options.addPreference('browser.download.folderList', 2)
        options.addPreference('browser.helperApps.alwaysAsk.force', false)
        options.addPreference('browser.download.manager.showWhenStarting', false)
        options.addPreference('browser.download.dir', GlobalVariable.downloadPath)
        options.addPreference('browser.download.downloadDir', GlobalVariable.downloadPath)
        options.addPreference('browser.download.defaultFolder', GlobalVariable.downloadPath)
        options.addPreference('browser.helperApps.neverAsk.saveToDisk', 'application/download, application/octet-stream, text/csv')

        WebDriver driver = new FirefoxDriver(options);
        // let Katalon Studio to use the WebDriver created here
        DriverFactory.changeWebDriver(driver)
        break
    default:
        WebUI.openBrowser('')
}

请注意，如果要下载不同的文件类型，必须在“browser.helperApps.neverAsk.saveToDisk”首选项中指定所有必需的MIME类型。可以在此处找到MIME类型列表：

此外，如果文件为PDF，则必须再添加一个首选项：

options.addPreference('pdfjs.disabled', true)
