Thanks, Matthew. Maybe some examples in the docs of the preferred way
to use `racketinput` with single- and multi-line results would be good.
For a long time, I've been doing both of the following, and I could
always see that they were wrong:

Yes, I usually use a mix of SXPath and `sxml-match`.
Yes. That certainly seems helpful, thanks.

Phil, can you let me know whether this new document clears up
everything? http://www.neilvandyke.org/racket/sxml-intro/

Hi everyone,
I'm trying to write a little program to extract some data from a web-page.
But when I hit Stack Overflow with it, I'm getting some strange errors (I
documented them here :

Now I stumbled
It is possible you're using the #:cycles-ok argument, as in the
program below? If so, that means that the reduction graph has no
irreducible terms. So you would need to pass no "expected" arguments
to test-->> in order for the test case to pass.

Hi, Brina.
This is my README of how I use RackUnit in my project.

I'm toying around with porting a small Elixir program to Racket. The following
gist has both programs:
https://gist.github.com/lojic/66c00514dab54b84c56e
One thing that's quite awkward in my Racket version is the need for the extra
place channels (ch1, ch2).
So, for example, the size
Not exactly. I'm looking for a way to run a function before *each*, of possibly
many, test-cases. The test-suite #:before only runs once before running all the
test-cases.
Although my gist: https://gist.github.com/lojic/db7016fb95b1c05e4ade only has a
few test-cases, if there were many, the
Are you looking for something like this:
#lang racket
(require rackunit rackunit/text-ui)
(define my-database #f)
(define my-first-test-suite
(test-suite
"An example suite"
#:before (lambda () (set! my-database '(a b c)) (displayln `(Before
,my-database)))
#:after (lambda ()
One reason to want that kind of functionality is to maintain good source
location information on test failures (which helper functions don't).

I agree that it's trivial to add, but for something as common as "setup" and

Dear colleagues,
I'm working on a semantics using Redex.
I've got a strange message from "test-->>" function --- "got nothing".
It is strange, because a term, which I run "test-->>" on, definitely can be
reduced.
For example, I can see lots of its productions in "traces" or "stepper".

Hi Brian,
Can you explain what you want to write? Just imagine that the feature was
already there... what do you want?
I think of Rackunit as a way of writing checks, so if I wanted to do what
you're talking about, then I'd define the macro/function that you don't
want to. In other words, with
Does RackUnit provide a facility similar to the setup & teardown functions of
other unit testing frameworks? In other words, I'd like to execute some code
before each test w/o coding each test to call a setup function or having to
create my own macro given how common this is.
As far as I can

I've added support for that (a new preference is in the drracket
preferences dialog).
I'm still hopeful that someone else will look into
