Querying Reagent/Hiccup Markup For Tests

Question

I want to test a Reagent/Re-Frame view by asserting properties of the Hiccup markup it returns. Therefore I need functions that traverse the tree, filter it, or check that certain elements with certain attributes are present.

I can not be the first to have this problem, yet Google wasn't very helpful. Is there a library that does that? If not, how would you, e.g., write a function that traverses the markup and returns a seq of all elements with a certain tag?

Please specify your actual problem and the code, that failed. — cfrick, Apr 24 '20 at 16:34

I'd be looking at:

Convert the hiccup out to HTML then use HTML selectors to do analysis
Put the tree inside DataScript then use datalog to do analysis
- More details here https://juxt.pro/blog/posts/datascript-dom.html
Explore the sea of libraries for data filtering:

- https://github.com/BrunoBonacci/where

There's a lot of ways of doing this it's hard to suggest a good answer

You can analyze and modify any tree-like data structure using the Tupelo Forest library. Please view the Lightning Talk video and peruse the many live examples.

If you add more detail to your question I can update the answer with something specific.

It seems to me that `tupelo.forest` isn't available in ClojureScript, or am I doing something wrong? – Teresa Siegmantel Apr 24 '20 at 08:11
Oh, yes, it is CLJ only at present. I am working on an upgrade that will support CLJS also. You could use the `walk-with-parents-readonly` as a temporary workaround. – Alan Thompson Apr 24 '20 at 09:03
