我正在使用以太坊平台开发简单的DApp。在这方面，我使用了摩卡测试框架，但出现了此错误。请帮忙...

我得到了答案。我正在发布它，以便它可以对其他人有所帮助......
前面我已经将我的描述方法定义为：
describe(() => {
it("can pass the test", () => {
console.log(accounts);
});
}(; 错误图像
在这里，我已经传递了直接函数，而不是先进行 tittle 这就是为什么摩卡无法成功并返回错误的原因：
套件参数"title"必须是字符串。接收类型"函数">
但是在给出我的合同方法后，它接受它作为一个花絮
describe( 'inbox', () => {
it("can pass the test", () => {
console.log(accounts);
});
}(; 最终图像
