如何让Selenium webdriver读取csv文件以执行操作。我有我的脚本将其加载到浏览器中并执行操作如何使其读取csv文件并将该操作替换为csv文件中的数据

Answer 1

执行此操作的最佳方法是使用另一个专门进行此类解析的库，并将其提供给内存。关于此问题的一个很好的StackOverflow问题是here。

Answer 2

请记住，WebDriver只是与浏览器进行交互。这是你写作文件IO的语言。我建议创建一个CSV类。由于csv只是一个文本文件，因此您可以将其作为字符串读取并遍历每一行。用逗号分开，你很高兴。你没有指定一种语言，所以这里是我们库中C＃的一个例子。注意我使用yield来提高效率。这是我在某处找到的东西。无需重新发明轮子。

public static class CSV
{
    private static bool ignoreFirstLineDefault = false;

    public static IEnumerable<IList<string>> FromFile(string fileName)
    {
        foreach (IList<string> item in FromFile(fileName, ignoreFirstLineDefault)) yield return item;
    }

    public static IEnumerable<IList<string>> FromFile(string fileName, bool ignoreFirstLine)
    {
        using (StreamReader rdr = new StreamReader(fileName))
        {
            foreach (IList<string> item in FromReader(rdr, ignoreFirstLine)) yield return item;
        }
    }

    public static IEnumerable<IList<string>> FromStream(Stream csv)
    {
        foreach (IList<string> item in FromStream(csv, ignoreFirstLineDefault)) yield return item;
    }

    public static IEnumerable<IList<string>> FromStream(Stream csv, bool ignoreFirstLine)
    {
        using (var rdr = new StreamReader(csv))
        {
            foreach (IList<string> item in FromReader(rdr, ignoreFirstLine)) yield return item;
        }
    }

    public static IEnumerable<IList<string>> FromReader(TextReader csv)
    {
        //Probably should have used TextReader instead of StreamReader
        foreach (IList<string> item in FromReader(csv, ignoreFirstLineDefault)) yield return item;
    }

    public static IEnumerable<IList<string>> FromReader(TextReader csv, bool ignoreFirstLine)
    {
        if (ignoreFirstLine) csv.ReadLine();

        IList<string> result = new List<string>();

        StringBuilder curValue = new StringBuilder();
        char c;
        c = (char)csv.Read();
        while (csv.Peek() != -1)
        {
            switch (c)
            {
                case ',': //empty field
                    result.Add("");
                    c = (char)csv.Read();
                    break;
                case '"': //qualified text
                case '\'':
                    char q = c;
                    c = (char)csv.Read();
                    bool inQuotes = true;
                    while (inQuotes && csv.Peek() != -1)
                    {
                        if (c == q)
                        {
                            c = (char)csv.Read();
                            if (c != q)
                                inQuotes = false;
                        }

                        if (inQuotes)
                        {
                            curValue.Append(c);
                            c = (char)csv.Read();
                        }
                    }
                    result.Add(curValue.ToString());
                    curValue = new StringBuilder();
                    if (c == ',') c = (char)csv.Read(); // either ',', newline, or endofstream
                    break;
                case '\n': //end of the record
                case '\r':
                    //potential bug here depending on what your line breaks look like
                    if (result.Count > 0) // don't return empty records
                    {
                        yield return result;
                        result = new List<string>();
                    }
                    c = (char)csv.Read();
                    break;
                default: //normal unqualified text
                    while (c != ',' && c != '\r' && c != '\n' && csv.Peek() != -1)
                    {
                        curValue.Append(c);
                        c = (char)csv.Read();
                    }
                    result.Add(curValue.ToString());
                    curValue = new StringBuilder();
                    if (c == ',') c = (char)csv.Read(); //either ',', newline, or endofstream
                    break;
            }

        }
        if (curValue.Length > 0) //potential bug: I don't want to skip on a empty column in the last record if a caller really expects it to be there
            result.Add(curValue.ToString());
        if (result.Count > 0)
            yield return result;

    }
}

我建议您使用Excel文件而不是csv。使用CSV时的限制是当你想在数据本身中使用分隔符'，'时如果您有一个地址字段，请在此处说出Gyandeep Colony, B. No : - 1/5'，'来打破您的代码。

我阅读数据的方式是使用我的实用程序代码

public class ExcelHandler {

public static String getSheetData(String path,String sheetName, int col , int row) {
    Workbook workbook;
    String data = null;
    try {
        workbook = Workbook.getWorkbook(new File(path));
        Sheet sheet = workbook.getSheet(sheetName);
         data  = sheet.getCell(row,col).getContents();

    } catch (BiffException e) {

        e.printStackTrace();
    } catch (IOException e) {

        e.printStackTrace();
    }

    return data;

}


public static String getSheetData(String path, int sheetNo, int col , int row) {
    Workbook workbook;
    String data = null;
    try {
        workbook = Workbook.getWorkbook(new File(path));
        Sheet sheet = workbook.getSheet(sheetNo);
         data  = sheet.getCell(row,col).getContents();

    } catch (BiffException e) {

        e.printStackTrace();
    } catch (IOException e) {

        e.printStackTrace();
    }

    return data;

}

}

我只是在我的代码中的任何地方调用这些方法。

让我们举个例子

WebElement username = driver.findElement(By.id("username"));
username.sendKeys(Utility.getSheetData("Login.xls",0,1,0));

快乐编码：）

$(function(){
$('select').change( function(){
    var value = $(this).val();
    if (value == 'new') {
        var other = prompt('Add new:');
        if(!other) return false;
        $(this).append('<option value"'
            + other
            + '" selected="selected">'
            + other
            + '</option>');
    }
});
});
