i don't think we actually need the parse transform. i think we can have the same syntax and use the imported function feature.

Possible related to the first answer mentioned on jimenezrick/vimerl#7

Auto indenting ends up with:

spec() ->
  describe("beforespec", fun() ->
        it("should do stuff", fun() ->
              io:format("output from: it should do stuff~n", [])
          end),
    end).

It should be:

spec() ->
    describe("beforespec", fun() ->
        it("should do stuff", fun() ->
            io:format("output from: it should do stuff~n", [])
        end),
    end).

rspec like instance variables

we should be able to support

Foo@ = setup_variable()

do_stuff_with(Foo@)

is that syntax too weird?

not sure exactly how this should work with before/after each/all

alternative 1)

each group/example creates its own variable context which is a copy of the outer variable context. this means examples/groups on the same level won't interfere with each other. but it also means an after_all in a group will only see variables set by a before_all in the same group or an outer group which limits what an after_all can clean up. i think that makes sense.

alternative 2)

do whatever rspec does...

Like the pending method in RSpec

we should have a thing that just automatically unloads all the mechs you have defined in a before or in an example.

for example

describe("foo", fun() ->
  before_each(fun() ->
    %load mech 1
  end),

  it("should do stuff", fun() ->
  end),

  describe("nested", fun() ->
    before_each(fun() ->
      % load mech 2
    end),
    it("should do more stuff", fun() ->
    end),
  end)
end)

is converted to

load mech 1
run "should do stuff"
unload mech 1

load mech 1
load mech 2
run "should do more stuff"
unload mech 2
unload mech 1

we should probably provide an option to auto-verify as well.

not sure if mech already has something to make this easy...

I want to make a standalone binary so it is easier to use in other projects. I used rebar escriptize in c5f15ec, which worked to generate a standalone binary, except that isn't enough.

The parse transform we have in include/espec.hrl also needs to be shared in the other projects, as spec files include it at the top.

We need to find a way to either not require this to be included and have the espec command do the work, or for the espec command to add this to the lib path before running specs (I guess it could write a temporary directory, then add that to the lib path).

Asserts like eunit, for example assertEqual, which when fail show you what was expected and what was returned. At the moment just a badmatch error is shown.

E.g.

Finished in 4.2 seconds
10 succeeded, 5 pending, 2 failures

I'm trying to use espec as a dep of my rebar project and I'm not sure how to use the command line tool. I've been using ./deps/espec/bin/espec but that seems to fail.

E.g.

        before_all(fun() ->
            % {undefined_module, nonexistant_module}
            ok = meck:new(nonexistant_module, [passthrough])
        end),

Probably also happens in before_each.
