## Assert
|
||
|
|
|
||
|
|
This module is used for writing unit tests for your applications, you can
|
||
|
|
access it with `require('assert')`.
|
||
|
|
|
||
|
|
### assert.fail(actual, expected, message, operator)
|
||
|
|
|
||
|
|
Tests if `actual` is equal to `expected` using the operator provided.
|
||
|
|
|
||
|
|
### assert.ok(value, [message])
|
||
|
|
|
||
|
|
Tests if value is a `true` value, it is equivalent to `assert.equal(true, value, message);`
|
||
|
|
|
||
|
|
### assert.equal(actual, expected, [message])
|
||
|
|
|
||
|
|
Tests shallow, coercive equality with the equal comparison operator ( `==` ).
|
||
|
|
|
||
|
|
### assert.notEqual(actual, expected, [message])
|
||
|
|
|
||
|
|
Tests shallow, coercive non-equality with the not equal comparison operator ( `!=` ).
|
||
|
|
|
||
|
|
### assert.deepEqual(actual, expected, [message])
|
||
|
|
|
||
|
|
Tests for deep equality.
|
||
|
|
|
||
|
|
### assert.notDeepEqual(actual, expected, [message])
|
||
|
|
|
||
|
|
Tests for any deep inequality.
|
||
|
|
|
||
|
|
### assert.strictEqual(actual, expected, [message])
|
||
|
|
|
||
|
|
Tests strict equality, as determined by the strict equality operator ( `===` )
|
||
|
|
|
||
|
|
### assert.notStrictEqual(actual, expected, [message])
|
||
|
|
|
||
|
|
Tests strict non-equality, as determined by the strict not equal operator ( `!==` )
|
||
|
|
|
||
|
|
### assert.throws(block, [error], [message])
|
||
|
|
|
||
|
|
Expects `block` to throw an error.
|
||
|
|
|
||
|
|
### assert.doesNotThrow(block, [error], [message])
|
||
|
|
|
||
|
|
Expects `block` not to throw an error.
|
||
|
|
|
||
|
|
### assert.ifError(value)
|
||
|
|
|
||
|
|
Tests if value is not a false value, throws if it is a true value. Useful when testing the first argument, `error` in callbacks.
