java : collection : listfiles

Question

我想使用列表文件而不是手动设置对象集合:

@Paramaters
public static Collection<Object[]> data()
{
     Object[][] data = new Object[][]{{"test_files/myfilea.txt"}, {"test_files/myfileb.txt"},{"test_files/myfilec.txt"},{"test_files/myfiled.txt"}};

return Arrays.asList(data);
}

任何想法，解决方案，请。

Answer 1

这样做

File theDirectory = new File("test_files");
File[] theFiles;
if(theDirectory.isDirectory()) 
    theFiles = theDirectory.listFiles();
else
    return null; //Or throw exception... up to you
List<Object[]> yourFilesList = new ArrayList<Object[]>();   //Edited here
for(File f: theFiles)
{
    if(f.isFile())
        //yourFilesList.add(new Object[]{f.getName()});       //Edited here again
        // or your code may rely on directory also so you can do this
         yourFilesList.add(new Object[]{"test_files/" + f.getName()}); 
}
return yourFilesList;
