For those tasks I use most of the time block selection.

Put your cursor on the first # character, press Ctrl``V (or Ctrl``Q for gVim), and go down until the last commented line and press x, that will delete all the # characters vertically.

For commenting a block of text is almost the same: First, go to the first line you want to comment, press Ctrl``V, and select until the last line. Second, press Shift``I``#``Esc (then give it a second), and it will insert a # character on all selected lines. For the stripped-down version of vim shipped with debian/ubuntu by default, type : s/^/# in the second step instead.

Using py.test is great and the support for test fixtures is pretty awesome. However, in order to share your fixtures across your entire module, py.test suggests you define all your fixtures within one single conftest.py file. This is impractical if you have a large quantity of fixtures -- for better organization and readibility, you would much rather define your fixtures across multiple, well-named files. But how do you do that? ...No one on the internet seemed to know.

Turns out, however, you can define fixtures in individual files like this:

tests/fixtures/add.py

import pytest

@pytest.fixture

	class Program
	{
	static void Main(string[] args)
	{
	MainAsync().Wait();
	}

	static async Task MainAsync()
	{
	CancellationTokenSource cts = new CancellationTokenSource();

	var mongoObjectId = function () {
	var timestamp = (new Date().getTime() / 1000 \| 0).toString(16);
	return timestamp + 'xxxxxxxxxxxxxxxx'.replace(/[x]/g, function() {
	return (Math.random() * 16 \| 0).toString(16);
	}).toLowerCase();
	};
