Question

我在selenium java中编写了一个自动化测试，用于检测页面是否重定向（自动检测是否打开了新页面，页面重定向到其他页面，打开了新选项卡以及是否打开了警报窗口）< / p>

现在问题。其中一个重定向我找不到任何方法来检测是一个自动下载的文件（你进入一个网站，网站自动下载文件，没有任何来自用户的触发器）

P.S。

我知道每个浏览器的下载过程可能不同，我需要它主要用于chrome

谢谢

Answer 1

我有同样的问题，这是我在互联网上找到的地方（也许是在stackoverflow，我不记得了）。我刚刚添加了一行来删除文件，以便在测试开始时调用此方法，我确保在尝试再次下载时该文件不再存在。

  public boolean isFileDownloaded(String downloadPath, String fileName) {
  File dir = new File(downloadPath);
  File[] dirContents = dir.listFiles();

  for (int i = 0; i < dirContents.length; i++) {
      if (dirContents[i].getName().equals(fileName)) {
          // File has been found, it can now be deleted:
          dirContents[i].delete();
          return true;
      }
          }
      return false;
  }

你只需要用这一行来打电话： isFileDownloaded（＆＃34; C：\ Path \ To \ Your \ Folder＆＃34;，＆＃34; yourPdfFile.abc＆＃34;）;

希望这有帮助！

Answer 2

我的解决方案是在打开页面之前和之后计算下载目录中的文件。

我很高兴知道是否有人知道找到下载触发器的方法

Answer 3

我使用了“存在”方法

public boolean isFileDownloaded() throws Exception {
    final int SLEEP_TIME_MILLIS = 1000;
    File file = new File(filePath);
    final int timeout = 60* SLEEP_TIME_MILLIS;
    int timeElapsed = 0;
    while (timeElapsed<timeout){
        if (file.exists()) {
            System.out.println(fileName + " is present");
            return true;
        } else {
            timeElapsed +=SLEEP_TIME_MILLIS;
            Thread.sleep(SLEEP_TIME_MILLIS);
        }
    }
    return false;
}

Answer 4

我在自动化中处理类似的情况。

步骤1：使用chrome首选项

在chrome中设置下载路径

ChromeOptions options = new ChromeOptions();

HashMap<String, Object> chromePref = new HashMap<>();

chromePref.put("download.default_directory", <Directory to download file>);

options.setExperimentalOption("prefs", chromePref);

确保您下载的文件夹中没有包含预期文件名的文件。

第2步：导航到chrome中的url，文件将自动下载到指定的文件夹中。

步骤3：检查下载文件夹中是否存在文件。

Answer 5

我使用了来自不同来源的组合变体：

覆盖默认下载文件夹：

ChromeOptions options = new ChromeOptions();
HashMap<String, Object> chromePref = new HashMap<>();
chromePref.put("download.default_directory", System.getProperty("java.io.tmpdir"));
options.setExperimentalOption("prefs", chromePref);
WebDriver driver = new ChromeDriver(options);

方法正文：

WebDriverWait wait = new WebDriverWait(driver, 5);
String tmpFolderPath = System.getProperty("java.io.tmpdir");
String expectedFileName = "Some_file_name.ext";
File file = new File(tmpFolderPath + expectedFileName);
if (file.exists())
    file.delete();
// Start downloading here.
wait.until((ExpectedCondition<Boolean>) webDriver -> file.exists());
// Do what you need.

Answer 6

我开发了library，在这种情况下处理得更清楚。您可以使用给定的下载文件夹生成ChromeOptions对象，并使用单行方法调用来下载文件并验证继承：

private SeleniumDownloadKPI seleniumDownloadKPI;

@BeforeEach
void setUpTest() {
    seleniumDownloadKPI =
         new SeleniumDownloadKPI("/tmp/downloads");
    ChromeOptions chromeOptions =
            seleniumDownloadKPI.generateDownloadFolderCapability();
    driver = new ChromeDriver(chromeOptions);
}

@Test
void downloadAttachTest() throws InterruptedException {
    adamInternetPage.navigateToPage(driver);
    seleniumDownloadKPI.fileDownloadKPI(
            adamInternetPage.getFileDownloadLink(), "SpeedTest_16MB.dat");
    waitBeforeClosingBrowser();
}

Answer 7

这种方法对我来说成功了

 /**
     * This method will wait until the folder is having any downloads
     * @throws InterruptedException 
     */
    public static void waitUntilFileToDownload(String folderLocation) throws InterruptedException {
        File directory = new File(folderLocation);
        boolean downloadinFilePresence = false;
        File[] filesList =null;
        LOOP:   
            while(true) {
                filesList =  directory.listFiles();
                for (File file : filesList) {
                    downloadinFilePresence = file.getName().contains(".crdownload");
                }
                if(downloadinFilePresence) {
                    for(;downloadinFilePresence;) {
                        sleep(5);
                        continue LOOP;
                    }
                }else {
                    break;
                }
            }
    }

Answer 8

这非常适合我：

  public static void waitForTheExcelFileToDownload(String fileName, int timeWait)
                throws IOException, InterruptedException {
            String downloadPath = getSystemDownloadPath();
            File dir = new File(downloadPath);
            File[] dirContents = dir.listFiles();

            for (int i = 0; i < 3; i++) {
                if (dirContents[i].getName().equalsIgnoreCase(fileName)) {
                    break;
                }else {
                    Thread.sleep(timeWait);
                }
            }
        }

Answer 9

希望这会有所帮助！

public static Boolean isFileDownloaded(String fileName) {
        boolean flag = false;
        //paste your directory path below
        //eg: C:\\Users\\username\\Downloads
        String dirPath = ""; 
        File dir = new File(dirPath);
        File[] files = dir.listFiles();
        if (files.length == 0 || files == null) {
            System.out.println("The directory is empty");
            flag = false;
        } else {
            for (File listFile : files) {
                if (listFile.getName().contains(fileName)) {
                    System.out.println(fileName + " is present");
                    break;
                }
                flag = true;
            }
        }
        return flag;
    }

Answer 10

在当前用户的下载文件夹中的脚本执行文件下载过程中。

使用下面的代码检查和下载文件

public void  delte_file(String filename)

{
    String home = System.getProperty("user.home");
    String file_name = filename;
    String file_with_location = home + "\\Downloads\\" + file_name;
    System.out.println("Function Name ===========================" + home + "\\Downloads\\" + file_name);
    File file = new File(file_with_location);
    if (file.exists()) {
        System.out.println(file_with_location + " is present");
        if (file.delete()) {
            System.out.println("file deleted");
        } else {
            System.out.println("file not deleted");
        }
    } else {
        System.out.println(file_with_location + " is not present");
    }
}

要检查文件是否存在，请使用以下代码：

public static String  check_file_exist(String filename)
    {
        String home = System.getProperty("user.home");
            String file_name = filename;
        String file_with_location = home + "\\Downloads\\" + file_name;
        System.out.println("Function Name ===========================" + home + "\\Downloads\\" + file_name);
        File file = new File(file_with_location);
        if (file.exists()) {
            System.out.println(file_with_location + " is present");
            String result = "File Present";
            return result;
        } else {
            System.out.println(file_with_location + " is not present");
            String result = "File not Present";
            String result1 = result;
            return result1;
        }
    }

Answer 11

   String downloadPath = "C:\\Users\\Updoer\\Downloads";
   File getLatestFile = getLatestFilefromDir(downloadPath);
   String fileName = getLatestFile.getName();
   Assert.assertTrue(fileName.equals("Inspections.pdf"), "Downloaded file 
   name is not matching with expected file name");

----------------每次您需要删除下载的文件时，请添加此代码也---------

   File file = new File("C:\\Users\\Updoer\\Downloads\\Inspections.pdf"); 
   if(file.delete())
       System.out.println("file deleted");
 System.out.println("file not deleted");

-----在此代码下添加方法-------

    private File getLatestFilefromDir(String dirPath){
    File dir = new File(dirPath);
    File[] files = dir.listFiles();
    if (files == null || files.length == 0) {
        return null;
    }

    File lastModifiedFile = files[0];
    for (int i = 1; i < files.length; i++) {
       if (lastModifiedFile.lastModified() < files[i].lastModified()) {
           lastModifiedFile = files[i];
       }
    }
    return lastModifiedFile;
    }
