Node Assert section method 

Assert (value[, message]) assert.ok(value[, message]) assert() is short for assert.ok() and can be used the same way. If the value of value istrueThen nothing will happen. If the value isfalseWill throw an error with the message message. Value. Equal (actual, expected[, message]) determines whether actual and expected values are equal(==) and when this is not value, a message error is thrown. Assert.deepequal (actual, Expected [, message]) deep means that enumerable attributes of child objects are also counted. Passes if both its property and its child property are equal. Otherwise an error is thrown. Assert. DeepStrictEqual (actual, Expected [, message]) determines whether the depth is strictly equal. assert.notDeepEqual(actual, expected[, message]) assert.notDeepStrictEqual(actual, expected[, message]) assert.notEqual(actual, expected[, message]) assert.notStrictEqual(actual, expected[, message]) assert.strictEqual(actual, expected[, message]) assert.throws(block[, error][, message])Copy the code
