[Bug]: __mock.module_info hasn't enough data

[0legovich]

Describe the bug

I tried to write a simple test for my module and get unexpected error

/soldr-modules/utils/mock/core.lua:864: /soldr-modules/utils/engine/event.lua:488: attempt to call field 'fields_schema_validator' (a nil value)

After a little research, I realized that __mock.module_config hasn't enough data. I found the row with initializing and containing __mock.module_info https://github.com/vxcontrol/soldr-modules/blob/master/utils/mock/core.lua#L693 and was unhappy surprised there are no fields: fields, actions, events. As I understand __mock.module_info should contains data from file <module_name>/<version>/config/info.json.

I crookedly fixed it in my module, but it will be better if __mock.module_info contains real data from <module_name>/<version>/config/info.json.

Steps to Reproduce

• prepare environment by Wiki: https://github.com/vxcontrol/soldr-modules/wiki/Unit-testing

• cd soldr-modules

• git fetch origin osquery_linux (if not merged)

• Import test code:

cat << EOF > ./tests/osquery_linux_client_spec.lua
require 'busted.runner'()

describe('osquery_linux agent', function()
    setup(function()
        _G.__mock = {
            vars = {},
            timeout = 2, -- in seconds
            cwd = "tmpcwd",
            module = "osquery_linux",
            version = "1.0.0",
            side = "agent",
            log_level = os.getenv("LOG_LEVEL") or "debug", -- error, warn, info, debug, trace
        }
        require("mock")
        __mock:module_start()
    end)

    teardown(function()
        -- stop module actually wait for module coroutine to finish execution
        __mock:module_stop()
    end)

    before_each(function()
        __mock:clear_expectations()
    end)
end)
EOF

• Run test:
  ./tests_framework/lua/bin/busted.osx64.cmd tests/osquery_linux_client_spec.lua

Expected behavior:

1 success / 0 failures / 0 errors / 0 pending : 0.288752 seconds

Actual behavior:

0 successes / 0 failures / 1 error / 0 pending : 0.213859 seconds
