传统的断言模式


传统的断言模式在以下方法中使用抽象的相等性比较

使用传统的断言模式:

const assert = require('assert');

只要有可能,请使用严格的断言模式。 否则,抽象的相等性比较可能会导致意外的结果。 特别是对于 assert.deepEqual(),其中的比较规则是松散的:

// 注意:这不会抛出 AssertionError!
assert.deepEqual(/a/gi, new Date());

Legacy assertion mode uses the Abstract Equality Comparison in:

To use legacy assertion mode:

const assert = require('assert');

Whenever possible, use the strict assertion mode instead. Otherwise, the Abstract Equality Comparison may cause surprising results. This is especially true for assert.deepEqual(), where the comparison rules are lax:

// WARNING: This does not throw an AssertionError!
assert.deepEqual(/a/gi, new Date());
