松露測試錯誤

我想創建一個去中心化的應用程序來出售我的代幣。所以，在這種情況下。我創建一個函式來結束我的代幣銷售。所以，我在下面創建一個函式。

堅固性程式碼在這裡： -

function endSale() public {
    require(msg.sender == admin);
    require(tokenContract.transfer(admin,tokenContract.balanceOf(this)));    
    selfdestruct(admin);
   }

松露java腳本測試程式碼在這裡： -

it('ends token sale', function() {
  `enter preformatted text here` return DappToken.deployed().then(function(instance) {
     // Grab token instance first
     tokenInstance = instance;
     return DappTokenSale.deployed();
   }).then(function(instance) {
     // Then grab token sale instance
     tokenSaleInstance = instance;
     // Try to end sale from account other than the admin
     return tokenSaleInstance.endSale({ from: buyer });
   }).then(assert.fail).catch(function(error) {
     assert(error.message.indexOf('revert' >= 0, 'must be admin to end sale'));
     // End sale as admin
     return tokenSaleInstance.endSale({ from: admin });
   }).then(function(receipt) {
     return tokenInstance.balanceOf(admin);
   }).then(function(balance) {
     assert.equal(balance.toNumber(), 999990, 'returns all unsold dapp tokens to admin');
     // Check that token price was reset when selfDestruct was called
     return tokenSaleInstance.tokenPrice();
   }).then(function(price) {
     assert.equal(price.toNumber(), 0, 'token price was reset');
   });
 });

當我通過 truffle test 命令對其進行測試時，出現以下錯誤：-

Error: Attempting to run transaction which calls a contract function, but recipient address 0x970c30c59d21df9fe660a266faf2ba0871dc25ad is not a contract address

因此，任何人都可以幫助我解決此類錯誤。請告訴我我在程式碼中的錯誤位置。

嘗試selfdestruct從 endSale 函式中刪除函式呼叫。

您不能tokenSaleInstance.tokenPrice()在之後呼叫，tokenSaleInstance.endSale({ from: admin })因為在那之後契約不再存在。

正如@ThorkilVærge 所建議的，如果您需要價格，您可以移除 selfdestruct。另一種選擇是在呼叫之前檢索價格endSale()。
