I'm using it to instrument a running development system as I'm working with
it, via an API, REPL, and tests. I've found it handy in all three places
for my :ret specs to be checked when the function runs, and quickly
detecting problems in my spec or function. I can see how :ret and :fn are
invaluable for generative tests, but in my experience it is also very
useful to check them in other places. As far as I can tell, the only
downside to checking :fn and :ret specs while in development is that it
takes marginally more CPU to check them. Maybe I'm missing something though?

I find it funny that Clojure strongly believes that static types aren't worth 
the effort in most cases, but somehow the effort of adding generative testing 
is.

I think it's great to encourage people to use generative testing, but I'd 
rather it be à la carte, like most other things in Clojure. Orchestra allows 
that. If you want your :fn and :ret spec validated only on your manual tests, 
or on your regression tests, it lets you do that.

2017-07-10 Thread Rick Moynihan 
It might be worth including a discussion about when to use this library,
and perhaps indicating that using it might not be a best-practice.

:ret and :fn specs were originally validated by instrument, but this
feature was removed because Rich et al thought it redundant, and that there
were different (and arguably better) tools for validating :ret specs, e.g.
check.

https://groups.google.com/d/msg/clojure/JU6EmjtbRiQ/WSrueFvsBQAJ

For what it's worth I understand why you might want to use this, and it's
nice to have the option if you have a legacy test suite that you want to
incorporate some specs/validation with, but if you're using it you're doing
example based testing and not the generative testing which spec seems
intended to encourage.

2017-07-09 Thread Daniel Compton 
Thanks Jeaye, I'm really happy to see this for CLJS too!

Orchestra has been an excellent development time addition to our apps.
Checking the :ret specs is very helpful for finding the error in code as
close as possible to the problem, rather than further downstream when a
further spec fails.

[ANN] Orchestra 2017.07.04-1 (now supporting ClojureScript)

2017-07-08 Thread Jeaye 
Folks,

I'm happy to announce that a new version of Orchestra has been released this 
past week.

# Where to find it?
https://github.com/jeaye/orchestra
[orchestra "2017.07.04-1"]

# What is it?
Orchestra is a Clojure(Script) library made as a drop-in replacement for 
clojure.spec.test.alpha, which provides custom instrumentation that validates 
all aspects of function specs. By default, clojure.spec will only instrument 
:args. This leaves out :ret and :fn from automatic validation; Orchestra checks 
all of them for you.

# What changed since 0.3.0?
ClojureScript support!

# Any more info?
You can read my call to arms for instrumentation here: 
https://blog.jeaye.com/2017/05/31/clojure-spec/ Also, some notes on porting 
Orchestra to ClojureScript, which extend to porting Clojure projects to 
ClojureScript in general, here: 
https://blog.jeaye.com/2017/06/30/orchestra-cljs/

# When should I use it?
I strongly believe we can benefit from this instrumentation throughout the 
entire development cycle, so I recommend both your tests and your developments 
builds use instrumentation by default. If any functions misbehave, you'll know 
immediately and you'll have the context to find out why.

Cheers,
Jeaye
