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])
