assert(value[, message])

• {any} 测试值.
• {any} 错误抛出时显示的消息.

var assert = require('assert');

assert.assert(1);
// OK

assert.assert(true);
// OK

assert.assert(false);
// throws "AssertionError: false == true"

assert.assert(0);
// throws "AssertionError: 0 == true"

assert.assert(false, "it's false");
// throws "AssertionError: it's false"

doesNotThrow(block[, message])

• block {函数}
• message {any} 显示的消息.

var assert = require('assert');

assert.doesNotThrow(
  function() {
    assert.assert(1);
  }
);
// OK

assert.doesNotThrow(
  function() {
    assert.assert(0);
  }
)
// throws "AssertionError: Got unwanted exception."

equal(actual, expected[, message])

• actual {any} 实际值.
• expected {any} 预期值.
• message {any} 显示消息.

var assert = require('assert');

assert.equal(1, 1);
assert.equal(1, '1');

fail(actual, expected, message, operator)

• actual {any} 实际值.
• expected {any} 预期值.
• message {any} 显示消息.

var assert = require('assert');

assert.equal(1, 1);
assert.equal(1, '1');

notEqual(actual, expected[, message])

• actual {any} 实际值.
• expected {any} 预期值.
• message {any} 显示消息.

var assert = require('assert');

assert.notEqual(1, 2);

notStrictEqual(actual, expected[, message])

• actual {any} 实际值.
• expected {any} 预期值.
• message {any} 显示消息.

var assert = require('assert');

assert.notStrictEqual(1, 2);
// OK

assert.notStrictEqual(1, 1);
// AssertionError: 1 !== 1

assert.notStrictEqual(1, '1');
// OK

strictEqual(actual, expected[, message])

• actual {any} 实际值.
• expected {any} 预期值.
• message {any} 显示消息.

var assert = require('assert');

assert.strictEqual(1, 1);
// OK

assert.strictEqual(1, 2);
// AssertionError: 1 === 2

assert.strictEqual(1, '1');
// AssertionError: 1 === '1'

throws(block[, expected, message])

• block {Function} 在函数中抛出异常.
• expected {Function} 预期的异常错误.
• message {any} 显示消息.

var assert = require('assert');

assert.throws(
  function() {
    assert.equal(1, 2);
  },
  assert.AssertionError
);
// OK

assert.throws(
  function() {
    assert.equal(1, 1);
  },
  assert.AssertionError
);
// Uncaught error: Missing exception
