[英]How to check if a file has been downloaded successfully with selenium webdriver?
[英]How to check whether a zip file is successfully downloaded or not using java-selenium webdriver?
我從應用程序下載多個zip文件,每個文件都有不同的大小。 顯然,下載時間取決於文件大小。 我有以下java代碼來檢查基於文件大小的下載。但它沒有按預期工作。它只是等待10秒並通過繼續到下一組行終止循環。 有人可以幫我解決這個問題嗎?
public void isFileDownloaded(String downloadPath, String folderName) {
String source = "downloadPath" + folderName + ".zip";
long fileSize1;
long fileSize2;
do {
System.out.println("Entered do-while loop to check if file is downloaded successfully");
String tempFile = source + "crdownload";
fileSize1 = tempFile.length(); // check file size
System.out.println("file size before wait time: " + fileSize1 + " Bytes");
Thread.sleep(10); // wait for 10 seconds
fileSize2 = tempFile.length(); // check file size again
System.out.println("file size after wait time: " + fileSize2 + " Bytes");
} while (fileSize2 != fileSize1);
}
等待時間之前和之后的fileSize總是返回43個字節。
這是我管理下載文件的方式:
public class Rahul {
String downloadDir = "C:\\Users\\pburgr\\Downloads\\";
public WebDriverWait waitSec(WebDriver driver, int sec) {
return new WebDriverWait(driver, sec);
}
public File waitToDownloadFile(WebDriver driver, int sec, String fileName) {
String filePath = downloadDir + fileName;
waitSec(driver, 30).until(new Function<WebDriver, Boolean>() {
public Boolean apply(WebDriver driver) {
if (Files.exists(Paths.get(filePath))) {
System.out.println("Downloading " + filePath + " finished.");
return true;
} else {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
System.out.println("Downloading " + filePath + " not finished yet.");
}
}
return false;
}
});
File downloadedFile = new File(filePath);
return downloadedFile;
}
}
取兩個字符串列表:
List<String> expectedFileName ;
在此列表中添加您必須具有的字符串格式的每個文件名。[您的預期文件名]
然后在下載完所有文件后,轉到下載目錄:
使用以下代碼檢查存在多少文件:
new File(<directory path>).list().length
現在比較預期和實際的長度:
expectedFileName.size()
和new File(<directory path>).list().length
,如果有任何不匹配,則返回false並打印文件丟失 。如果沒有任何不匹配,則從目錄中獲取所有文件名,如下所示:
List<String> actualFileName;
File folder = new File("your/path");
File[] listOfFiles = folder.listFiles();
for (int i = 0; i < listOfFiles.length; i++) {
if (listOfFiles[i].isFile()) {
actualFileName.add(listOfFiles[i].getName());
}
}
現在你有兩個String列表,你可以輕松地比較它。 雖然它不會檢查文件大小。
