unable to run tests (compiling fails)

[murtaza52]

Hi,

I created a new project using lein new reagent hello-world +test. (The below is on a virgin project created using the template).

When I run lein cljsbuild test unit it throws the following error while compiling test.js -

Compiling ClojureScript. Compiling "target/test.js" from ["src/cljs"]... Compiling "target/test.js" failed. java.lang.NullPointerException at clojure.lang.Reflector.invokeNoArgInstanceMember(Reflector.java:301) at cljs.closure$load_externs$load_js3229$fn3230.invoke(closure.clj:223)

I get the same error while even doing a lein cljsbuild once. However lein fighweel compiles the code and does not throw an error.

Is some figwheel dependency causing a problem ? Can you please help, this is driving me crazy. Is there an alternate way to just run my tests ?

I can reproduce this, and it appears that it's related to figwheel, where the build is unable to find the namespace that it inject:

Caused by: clojure.lang.ExceptionInfo: No such namespace: figwheel.client, could not locate figwheel/client.cljs or figwheel/client.cljc at line 1 env/dev/cljs/hello_world/dev.cljs {:file "env/dev/cljs/hello_world/dev.cljs", :line 1, :column 1, :tag :cljs/analysis-error}

Looks like adding it as a dependency explicitly fixes the issue. I'll push out a new version with the fix:

:profiles {:dev {:repl-options {:init-ns hello-world.repl
                                  :nrepl-middleware [cemerick.piggieback/wrap-cljs-repl]}

                   :dependencies [[ring-mock "0.1.5"]
                                  [ring/ring-devel "1.3.2"]
                                  [weasel "0.6.0"]
                                  [leiningen-core "2.5.1"]
                  [lein-figwheel "0.3.3"]
                                  [com.cemerick/piggieback "0.2.1"]
                                  [org.clojure/tools.nrepl "0.2.10"]
                                  [pjstadig/humane-test-output "0.7.0"]]

new template is up and test seems to work as expected:

hello-world> lein cljsbuild test
Compiling ClojureScript.

Probably can remove the react preamble to silence the warning above.

gadfly ~/Desktop/hello-world $ lein cljsbuild test

[yogthos]

yeah that makes sense :)

[murtaza52]

Thanks for the prompt response. That saved my day !

How do you guys run your tests, if you never encountered the above problem ? Is there a better way to run them then lein cljsbuild test unit ?

[yogthos]

Figwheel allows reloading stuff on code change that's handy for automatically running the tests as seen here.

[yogthos]

@gadfly361 and just pushed out a new version without the preamble

[yogthos]

sounds like we can close this one then?

[murtaza52]

Dmitri how do I have two figwheel builds - the :main and the :test running at the same time.

lein figwheel only starts the main build. Also where will see the results after the test have run ? Any sample configs you can point me to.

Appreciate the help.

I don't have a sample config handy, but it's probably easiest to just add the test path to the dev resource-paths and have figwheel run the tests. The results should show up in the repl, you can also switch the figwheel repl to the test ns and run the tests from there as well.

I was about to open an issue on lein-figwheel, but it looks like @murtaza52 beat me to it. :)

For reference, that issue can be found here and the relevant clojure west talk can be found here.

Dmitri, I included the test sources, in :dev build :src. Now whenever there is a compilation error in the tests, I do see it in the browser. However how do I also get the tests to run when the src changes ?

Do you keep them running from the repl ?

Thanks for the help.

I don't understand why the namespace lookup didn't work. But you should just add the client and not the whole plugin to the dependencies [figwheel "0.3.3"].

[yogthos]

Is this still an issue or can we close it?

[yogthos]

I'm closing this one and we can reopen it if it's still a problem
