Unable to run rebar eunit configuration

[myles-mcdonnell]

When running rebar eunit config (skip deps = true, run in module = [none], command = eunit) it runs the following:

rebar eunit -C /private/var/folders/g6/snhc0p9n2ygdrxdrr07yj4k40000gp/T/eunit_teamcity9.tmp/rebar.config

which fails as this dir does not exist. Smells like an accidental commit from a dev.(or CI) env. to me, although maybe I'm doing something wrong as new to this party.

(Yosemite, IDJ 14.02, ErlangPlugin 0.5.9)

Hi @myles-mcdonnell!

Nothing accidental here. The plugin creates a temporary directory where it puts a copy of rebar.config from your project modified in order to attach eunit_teamcity reporter. It's weird if the temp directory isn't there as it's created each time you attempt to run the configuration.

Please re-check if the directory is there after you run the configuration, and if you still face the problem, share rebar's output.

[myles-mcdonnell]

Sorry, I'm not sure what you mean by "run the configuration"? I can run all rebar commands from a standalone terminal ok, including eunit.

My run config in IDJ as follows:

My rebar.config is as follows

{cover_enabled, true}.

{deps, [
{jiffy, ".*", {git, "https://github.com/davisp/jiffy.git"}}
]}.

Output from within IDJ is:

/Users/mylesmcdonnell/JsonErl/rebar eunit -C /private/var/folders/g6/snhc0p9n2ygdrxdrr07yj4k40000gp/T/eunit_teamcity10.tmp/rebar.config

I meant running rebar eunit configuration by "running the configuration", so you got me right.

Well, the output suggests we've done something wrong with the rebar.config (presumably, we've somehow output an incorrect configuration file there) - could you paste the content of /private/var/folders/g6/snhc0p9n2ygdrxdrr07yj4k40000gp/T/eunit_teamcity10.tmp/rebar.config here, please?

{cover_enabled, true}.

{deps, [
{jiffy, ".*", {git, "https://github.com/davisp/jiffy.git"}}
]}.{eunit_opts,[{report,{eunit_teamcity, []}},{no_tty, true}]}.

[myles-mcdonnell]

Got it, wants a line break after the '.' on line 5..

[deadok22]

Thank you, @myles-mcdonnell, I'll add a line break to the code which generates this file.

This is somewhat unexpected, though, as the issue hasn't been discovered before. What is your Erlang version?

[myles-mcdonnell]

R17.4.0 installed from here http://rudix.org/packages/erlang.html (yosemite)

If I add the line

{eunit_opts,[{report,{eunit_teamcity, []}},{no_tty, true}]}.

manually to the top of my rebar.config the config runs but reports empty test suite? This maybe unrelated.

If you want me to run a test on my system before you merge LMK, thanks @deadok22 .

[deadok22]

@myles-mcdonnell and does it work if you only add an extra newline at the end of your rebar.config?

If it still reports an empty suite and you're sure it's not empty, share more details on how your tests are written.

[myles-mcdonnell]

I've got the standard rebar template app with the eunit test code from https://github.com/rebar/rebar/wiki/Getting-started

-module(jsonErl_app).

-behaviour(application).

%% Application callbacks
-export([start/2, stop/1]).

-ifdef(TEST).
-include_lib("eunit/include/eunit.hrl").
-endif.

%% ===================================================================
%% Application callbacks
%% ===================================================================

start(_StartType, _StartArgs) ->
    jsonErl_sup:start_link().

stop(_State) ->
    ok.

-ifdef(TEST).

simple_test() ->
    ok = application:start(jsonErl),
    ?assertNot(undefined == whereis(jsonErl_sup)).

-endif.

this runs ok from the terminal with the following config:

{cover_enabled, false}.

{deps, [{jiffy, ".*", {git, "https://github.com/davisp/jiffy.git"}}]}.

but as reported previously from IDJ. If I add a new line empty to the top of the config, no change in either IDJ or Teminal results. If I add the team city config line, e.g.

{eunit_opts,[{report,{eunit_teamcity, []}},{no_tty, true}]}.

{cover_enabled, false}.

{deps, [{jiffy, ".*", {git, "https://github.com/davisp/jiffy.git"}}]}.

Then the output in IDJ is

/Users/mylesmcdonnell/JsonErl/rebar eunit -C /private/var/folders/g6/snhc0p9n2ygdrxdrr07yj4k40000gp/T/eunit_teamcity19.tmp/rebar.config

I've pushed a fix for this issue.

As to "Empty test suite." messages - ignore them. They're reported for modules which do not contain any eunit tests - try selecting different tests in the panel to the left of your console output.
