Question

I’m writing a coded ui test that is to act on a folder created every night. The way I want it to work is that the test will choose the newest folder.

How would I do this? Assertions?

The folder is being selected from a folder dialog box that I open with the main application. The name of the folder is then placed into a text box on the main app and scaned for patches.

 //Expand 'Computer' -> 'network drive (X:)' -> 'great-granparent' -> 'granparent' -> 'parent' -> 'folder' tree item
 uIfolder_TreeItem.Expanded = this.Browse_For_FolderParams.UIfolder_TreeItemExpanded;

Using nXu’s code I’ve tried this:

 DirectoryInfo root = new DirectoryInfo(@"X:\great-granparent\granparent\parent");
        DirectoryInfo[] folders = root.GetDirectories();

        DirectoryInfo newest = folders[0];
        foreach (var dir in folders)
        {
            if (dir.CreationTime.CompareTo(newest.CreationTime) > 0)
                newest = dir;
        }


        //Expand 'Computer' -> 'network drive (X:)' -> 'great-granparent' -> 'granparent' -> 'parent' -> 'folder' tree item
        newest = this.Browse_For_FolderParams(newest);

End Code

        DirectoryInfo root = new DirectoryInfo(@"X:\great-granparent\granparent\parent");
        DirectoryInfo[] folders = root.GetDirectories();

        DirectoryInfo newest = folders[0];
        foreach (var dir in folders)
        {
            if (dir.CreationTime.CompareTo(newest.CreationTime) > 0)
                newest = dir;
        }


        uIfolder_TreeItem.SearchProperties["Name"] = newest.Name;

        //Expand 'Computer' -> 'network drive (X:)' -> 'great-granparent' -> 'granparent' -> 'parent' -> 'folder' tree item
        uIfolder_TreeItem.Expanded = this.Get_FolderParams.UIfolder_TreeItemExpanded;

Thanks for the help 🙂

Use the DirectoryInfo class, it has CreationTime, LastAccessTime and LastWriteTime properties.
For example, to select the last created folder on C:\ root, use the following code:

DirectoryInfo root = new DirectoryInfo(@"C:\");
DirectoryInfo[] folders = root.GetDirectories();

DirectoryInfo max = folders[0];
foreach (var dir in folders)
{
    if (dir.CreationTime.CompareTo(max.CreationTime) > 0)
        max = dir;
}

// Last created directory is max
