# Final Test

Now that we have checked in most of the cases each contract individually. We are going to perform a test in order to assure that our DEX, XdYe works as expected before deploying Smart Contracts to Volta TestNet.

In here we are going to give a small brief of the tested critical aspects.

* We `mint` XdYe to ADD\[2]
* We `transfer` TKA & TKB to ADD\[2] from ADD\[0]
* We `transfer` XdYe to ADD\[3]
* We `approve` Router Contract to be able to manipulate TKA, TKB & XdYe from ADD\[2]
* We `addLiquidityETH` on pairs:
  * ETH - TKA
  * ETH - XDYE
  * ETH - TKB
* We check `getReserve` for the created Pairs
* We perform a `swapETHForExactTokens` for Pair *(ETH - TKA)* from ADD\[3]
* We check `getReserve` for the Pair in which we have performed the swap
* We perform a `swapETHForExactTokens` for Pair *(ETH - XDYE)* from ADD\[6]
* We check `getReserve` for the Pair in which we have performed the swap
* We `approve` XdYeBar Contract to manipulate XdYe Tokens from ADD\[3]
* We `enter` all XdYe Token balance that ADD\[3] has
* We check that ADD\[3] XdYe Token balance is now 0
* We `approve` Router Contract to be able to manipulate TKA from ADD\[3]
* We `swapTokensForExactTokens` for Pair *(TKA-TKB)* from ADD\[3], those tokens ADD\[3] has from previous ETH --> TKA swap
* We check ADD\[3] balances before & after the trade/swap
* We `approve` Router to be able to manipulate LP from ADD\[2] so it can remove ETH-TKA LPs
* We `removeLiquidityETH` for Pair *(ETH -* *TKA),* just 50% of it
* We check LP balance of ADD\[2] so we can assure the remove function has succeed
* We `approve` Router to be able to manipulate LP from ADD\[2] so it can remove ETH-XDYE LPs
* We `removeLiquidityETH` for Pair *(ETH -* *XDYE),* just 50% of it
* We check LP balance of ADD\[2] so we can assure the remove function has succeed
* We `approve` Router to be able to manipulate LP from ADD\[2] so it can remove TKA-TKB LPs
* We `removeLiquidity` for Pair *(TKA -* *TKB),* just 50% of it
* We check LP balance of ADD\[2] so we can assure the remove function has succeed
* Now LPs have been generated and transferred to XdYe Maker
* We `convert` WETH - TKA in XdYeMaker Contract
* We `convert` WETH - XdYe in XdYeMaker Contract
* We `convert` WETH - TKB in XdYeMaker Contract
* We `leave` all XdYe Token from XdYeBar Contract from ADD\[3]
* We check the XdYe Token balance of ADD\[3] after leaving XdYeBar
* Finally we check all addresses that have been used for the test and see if balances match the expected amount after all the system has been proven.
