You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: mod.rs
    path of file: ./repos/kernel/tests/common
    
    the code of the file until where you have to start completion: /// Common functionality for all integration tests
/// Note: If you encounter `error[E0463]: can't find crate for 'test'`, rememmber to add
/// `harness = false` to the [[test]] section of cargo.toml
pub extern crate alloc;

	pub fn padded_name(&self, column_count: usize, align: NamePadding) -> String {
		let mut name = String::from(self.name.as_slice());
		let fill = column_count.saturating_sub(name.len());
		let pad = " ".repeat(fill);
		match align {
			PadNone => name,
			PadOnRight => {
				name.push_str(&pad);
				name
