Which struture should I use for testing Yii2 modules

Hi everyone,

I have read the section about testing of Yii2. It is quite useful even not finished yet. In normally, the folder struture for test in Yii2 is as below:


/

...

tests/

--codeception/

----acceptance/

----functional/

----unit/

------components/

------models/

I confuse how structure directory test for modules. Should I use


/

...

modules/

--myModule/

----tests/

------acceptance/

------functional/

------unit/

Or


/

...

tests/

--codeception/

----modules/

------myModule/

--------acceptance/

--------functional/

--------unit/

----------components/

----------models/

----acceptance/

----unctional/

----unit/

Or


/

...

tests/

--codeception/

----acceptance/

------modules/

--------myModule/

----functional/

        modules/

          myModule/

----unit/

------modules/

--------myModule/

----------models/

------components/

------models/

Which should be the best approach?
