[英]Error using a smart contract variable in test.js file
Trying to use a variable called postCount from my smart contract in my test file which is returning an error undefined尝试在我的测试文件中使用我的智能合约中名为 postCount 的变量,该变量返回未定义的错误
Smart contract looks like:智能合约看起来像:
contract SocialNetwork {
string public name;
uint public postCount = 0;
Test file looks like:测试文件如下所示:
describe ('posts', async ()=> {
let result
before(async ()=> {
result = await socialNetwork.createPost('This is my first post', {
from: author
})
postCount = await socialNetwork.postCount()
})
On testing, error being returned is:在测试时,返回的错误是:
1) Contract: SocialNetwork
posts
"before all" hook:

Your Contract code should work fine.您的合同代码应该可以正常工作。 The Problem is your js variable postCount is not defined.问题是您的 js 变量 postCount 未定义。
describe ('posts', async ()=> {
let result;
let postCount;
before(async ()=> {
result = await socialNetwork.createPost('This is my first post', {
from: author
})
postCount = await socialNetwork.postCount()
})
