Chinese Engine Development

Could be less. Took China 30 years to put a little rabbit on the moon so I guess will be less.
To admit I don't think so ! There are just two Y-20 flying and both with the venerable D-30 ... I actually can't think that after just so few flight (or such a brief test-phase) so far the WS-20 was already tested on it.

There was a photo of a WS-20 engine in combination with DS-30 but on a flying IL-76. I don't think there is one with Y-20 and WS-20 engines..

Some not all. The article seems to be an aggregation of different rumours and leaks. In my opinion and by my own assessment the timeline is the most reliable piece, but it's also old news.
I think you got a translation problem, it didn't say the ws-15 would finish flight testing in 2014, it said the "验证机“ of the ws-15 would finish its test. "验证机“(I don't know the english word for it), is not even a prototype, before you build a prototype, you build a "验证机“ to test the basic design concept.

you're probably right. i'm not read up on chinese technical jargon, nor do i know all the stages of testing that aircraft engines have to go through before entering production. i took the term 验证机 to simply mean trial/testing aircraft, which gave the impression that the ws-15's "trial aircraft" would finish testing this year according to the timeline image mentioned in the article.
thanks for clearing things up, admittedly i did think the idea that the ws-15 would finish flight testing this year sounded dubiously optimistic, but it's what i took the article to be claiming.
Maybe it's the engine's core, which was already reported to be under test ! ... as such it would fit.
Anyway ... all hopes to see a WS-15-powered J-20 soon or hopes that it is already under test are pure dreams ... nice dreams, but dreams (for a few years to come).

The rumour mill suggests they completed core testing at the end of last year and started building a prototype/demonstrator around the same time, which sounds about right given that they started construction of the core as early as 2006. My guess is that that end of 2014 date is when they plan on validating the entire design from LP to AB. After that they'll probably have a proper prototype and begin endurance and altitude tests.
