在 Selenium 中使用 java 从另一个 CSV 文件读取用户名和密码后将用户名和密码写入 CSV 文件

Question

我已经编写了从 CSV 文件读取内容（用户名和密码）的代码。现在，我需要将这些内容写入另一个 CSV 文件。请帮我提供一个好的建议。

public class NewCsvClass {
    // private static final String FILE_HEADER = "Username,Password,Result";
    // private static final String NEW_LINE_SEPARATOR = "\n";
    public static void main( String[] args) throws Exception {

        // csv reader aswathy -start
        CSVReader reader = new CSVReader(new FileReader("/home/user/Documents/UrmilaDocs/CSV PAck/testCSV.csv"));
        String[] nextLine;

        WebDriver driver = new FirefoxDriver();
        String appUrl = "https://accounts.google.com";
        driver.get(appUrl);
        driver.manage().window().maximize();

        while ((nextLine = reader.readNext()) != null) {

            String user_name = nextLine[0];
            String pass_word = nextLine[1];

            System.out.println("Username: " + user_name);
            System.out.println("Password: " + pass_word);

            // //stackoverflow
            // WebDriver driver = new FirefoxDriver();
            // String appUrl = "https://accounts.google.com";
            // driver.get(appUrl);
            // driver.manage().window().maximize();

            WebElement username = driver.findElement(By.xpath(".//*[@id='Email']"));
            username.clear();
            username.sendKeys(user_name);
            driver.findElement(By.xpath(".//*[@id='next']")).click();

            Thread.sleep(5000);
            // try
            try {
                WebElement password = driver.findElement(By.xpath(".//*[@id='Passwd']"));
                password.clear();
                password.sendKeys(pass_word);
                driver.findElement(By.xpath(".//*[@id='signIn']")).click();
                Thread.sleep(8000);

                // click on 'Google Apps' icon
                driver.findElement(By.xpath(".//*[@id='gbwa']/div[1]/a")).click();
                Thread.sleep(10000);

                // Click on 'Gmail' icon to navigate to inbox page
                driver.findElement(By.xpath(".//*[@id='gb23']/span[1]")).click();
                Thread.sleep(10000);
                System.out.println("Login Success");

                // Click on user name first letter circle icon
                driver.findElement(By.xpath(".//*[@id='gb']/div[1]/div[1]/div[2]/div[4]/div[1]/a/span")).click();
                Thread.sleep(5000);

                // click on 'Signout' button
                driver.findElement(By.xpath(".//*[@id='gb_71']")).click();
                Thread.sleep(10000);
                System.out.println("Logout Success");

                /*
                 * click on 'Signin with a different account ' option (since, after signing out from // the first user,
                 * the page is navigated to password entry page, which is supposed to navigate to // username/mailid
                 * entry page
                 */

                try {
                    driver.findElement(By.xpath(".//*[@id='account-chooser-link']")).click();
                    // driver.findElement(By.xpath(".//*[@id='link-signin-different']/a")).click();
                    Thread.sleep(10000);
                } catch (Exception e) {
                }

                // /* In 'Choose an Account page', Click on 'Add Account' button */
                driver.findElement(By.xpath(".//*[@id='account-chooser-add-account']")).click();
                Thread.sleep(10000);
                //
            } catch (Exception e) {
                System.out.println("Login failed!");
                driver.findElement(By.xpath(".//*[@id='link-signin-different']/a")).click();
                Thread.sleep(10000);
                driver.findElement(By.xpath(".//*[@id='account-chooser-add-account']")).click();
                Thread.sleep(10000);

            } // catch closed
            // //closing driver & firefox
            // driver.close();
            // System.exit(0);
            // end
        } // while end

        // //closing driver & firefox
        // driver.close();
        // //csv reader aswathy -end
        System.exit(0); // closing firefox

        // Writing the CSV file to another CSV file
        String csv = "/home/user/Documents/UrmilaDocs/CSV PAck/testCSV.csv";
        CSVWriter writer = new CSVWriter(new FileWriter(csv));
        String[] username = "testuser01.zyx#testuser07#testuser2#testuser01.zyx#tester2.zyx#testernew779".split("#");
        String[] password = "testuser0123#user0123#user0123#user0123#user0123#user0123".split("#");
        writer.writeNext(username);
        writer.writeNext(password);
        writer.close();
    }
}

我没有看到导入语句，但您使用的是 com.csvreader.CsvWriter，即 JavaCSV API？

如果是这样，请尝试插入

writer.endRecord();

之前

writer.close();

Answer 2

数据对于执行测试用例起着非常重要的作用，利用它我们可以使用不同的测试数据进行数据质量测试。 为了执行这些操作，我们需要 Excel 或 csv 来存储数据。

OpenCSV 是一个用于读取数据并将数据写入 Excel 的库。

下面是向excel写入数据的代码：

文件 file = new File(filePath);

try { 
  
    // create FileWriter object with file as parameter 
    FileWriter outputfile = new FileWriter(file); 

    // create CSVWriter object filewriter object as parameter 
    CSVWriter writer = new CSVWriter(outputfile); 

    // Add header to csv 
    String[] header = { "StudentName", "Class", "ID" }; 
    writer.writeNext(header); 

    // Add data to csv 
    String[] data1 = { "Arman", "10", "1" }; 
    writer.writeNext(data1); 
    String[] data2 = { "Sanjay", "10", "2" }; 
    writer.writeNext(data2); 

    // closing writer connection 
    writer.close(); 
}
