Pages intentionally left blank?

[carols10cents]

There are multiple pages at the end of chapters that don't have any content on the page other than the page number and the chapter heading. Some chapters end as I would expect in a partial page.

Example of a blank page:

In the versions of the PDF generated on 2015-08-27 and 2015-08-21, the last page of Chapter 14 Advanced Unit Testing is totally blank (it's page 126 on the 27th and page 124 on the 21st). The fact that it's happening in 2 different versions makes me suspect that there's something in the PDF generation toolchain responsible.

Example of a partial page:

In the versions of the PDF generated on 2015-08-27 and 2015-08-21, the last page of Chapter 2 What Is Software Testing ends in a partial page (16 in both versions).

I wonder if it's trying to do something like not start a chapter on the right hand side if this were printed double-sided? But all the page numbers are even...

If this is intentional or acceptable, carry on :)

This is an intentional default behavior in the toolchain. The book is intended for two-sided printing, and as such, chapters should start on right-facing (odd-numbered) pages.

If a chapter happens to be an odd number of pages in length, a blank page is added to accomplish this.

Hmm ok. Sounds like this should be closed then! Silly legacy paper support ;)
