如何获取断言打印成功消息？

Question

这是我写的断言

assert.equal(0,0,"Test Passed);

我希望它会打印测试通过的消息,但它没有发生.但是,如果断言失败,则会显示消息以及错误.

如果测试成功,有没有办法打印消息？

根据消息来源,仅在断言失败时才打印消息.

assert.equal = function equal(actual, expected, message) {
  if (actual != expected) fail(actual, expected, message, '==', assert.equal);
};

这里只是为了完整性的定义fail.

function fail(actual, expected, message, operator, stackStartFunction) {
  throw new assert.AssertionError({
    message: message,
    actual: actual,
    expected: expected,
    operator: operator,
    stackStartFunction: stackStartFunction
  });
}
