--description--
请注意,本项目在 这个 Repl.it 项目 的基础上进行开发。你也可以从 GitHub 上克隆。
isTrue()
仅当给出的值为 Boolean 的 true
时可以通过测试;isNotTrue()
则会在给出除 true
以外的值时通过测试。
assert.isTrue(true, '可以通过,因为值的类型是布尔且值为 true');
assert.isTrue('true', '不能通过,因为值的类型是字符串);
assert.isTrue(1, '不过能通过,因为值是数字 1');
isFalse()
和 isNotFalse()
同样存在,表现与上面提到的两个方法类似。
--instructions--
使用 assert.isTrue()
或 assert.isNotTrue()
让测试通过。
--hints--
不应有未通过的测试
