Description

The doc comments for multiple functions in the require package have code examples that are invalid. Example:

The example reads:

	  if require.NoError(t, err) {
		   require.Equal(t, expectedObj, actualObj)
	  }

but the NoError() function does not return any value, so this is invalid.

There are similar invalid examples in the doc comments for NoErrorf, NotEmpty and NotEmptyf.
