我正在使用以太坊平台开发简单的DApp。在这种情况下,我使用了Mocha测试框架,但会出现此错误。请帮助...

我得到了答案。我正在发布它,以便对其他人有帮助...
我之前将我的describe方法定义为:
module.exports = {
target: 'web'
}
}); Error Image
在这里,我通过了直接函数,而不是先付诸表决,这就是为什么摩卡咖啡无法做到并返回错误:
Suite参数“ title”必须为字符串。收到类型“函数”
但是在提供了我的合同方式之后,它接受了它的所有权
describe(() => {
it("can pass the test", () => {
console.log(accounts);
});
}); Final Image
