研究方向

Read the Test/QuickCheck.purs definition linked in the issue, especially the Gen-based property API. The report asks to support testing effectful functions without unsafePerformEffect; use the Blockly code2blockly then blockly2code round trip as the example. Done means an effectful property can express that round trip and verify the original code is returned.

描述

status: needs more info

I have a case that I think is quite legitimate where I want to quickcheck an effectful function however I can't because https://github.com/purescript/purescript-quickcheck/blob/v5.0.0/src/Test/QuickCheck.purs#L97 uses the concrete Gen monad.

My usecase is testing Blockly code2blockly and blockly2code functions. Since Blockly is a very mutable javascript library, both code2blockly and blockly2code have Effect types. In order to test my implementation of these functions I can take some code and basically run code2blockly followed by blockly2code and I should get the original code back. Currently I'm doing this with unsafePerformEffect 😱 but since tests are actually Effects I don't think this is really necessary.
