[This post also appears\u00a0on <\/em><\/span>Dustin’s github blog<\/span><\/a><\/em>].<\/em><\/span><\/p>\n

I recently had a Membase<\/a> user point out a sequence of operations that led to an undesirable state. I\u2019ve got a lot of really good engine tests I\u2019ve written, but not this<\/em> case:<\/p>\n

\n
<\/div>\n
add with timeout -> wait for timeout -> add with timeout<\/div>\n<\/div>\n

The bug is pretty straightforward \u2013 expiry is lazy and it turns out I\u2019m not checking for expiry in this case. It was pretty easy to<\/p>\n

write this test, but immediately made me think about what other<\/em> cases weren\u2019t being run.<\/p>\n

Now, I know there are countless tools out there to aid in testing. I\u2019ve written another one. I probably spent an hour or so writing a framework to write and run all of the tests I needed. The difference between what I\u2019m describing here and, for example, quick check<\/a> is that I want something very simple to express actions that expect their environment to be in a particular state and will leave the environment in another state. Then I want to hit every possible arrangement of these actions to ensure they don\u2019t interfer with each other in unexpected ways.<\/p>\n

\"Permutations\"<\/div>\n

This blows up very quickly \u2013 specifically the number of tests generated for a test sequence of n<\/code> actions from a<\/code> possible actions is approximately an<\/sup><\/code>.<\/p>\n

Consider three defined actions permuted into sequences of two. That blows out to nine possibilites as shown in the diagram on the right.<\/p>\n

The actions in the diagram are defined with memcached semantics on a single key, so add<\/code> has a prerequisite that the item must not<\/em> exist and del<\/code> has a prerequisite that the item must<\/em> exist.<\/p>\n

The generated test expects success at each white box, failure at each red box, and tracks the expected state mutations to build assertions.<\/p>\n

\"BreakDancer<\/div>\n

My first test\u2026 um, test ran with 11<\/code> actions in sequences of 4<\/code> actions. I have more actions to go, but 4<\/code> is a pretty good length, so the chart at the left is going to demonstrate my growth rate.<\/p>\n

The awesome part is that it pointed out the original bug quite easily and another couple of bugs with limited effort.<\/p>\n

How Do I Use This?<\/h4>\n
\"action<\/div>\n

The API is so far pretty simple and composable. There are basically five classes (three are shown in the image on the right).<\/p>\n

Condition<\/h4>\n

A Condition<\/code> is a simple callable that is used for preconditions and postconditions. A given class doesn\u2019t care which one it\u2019s used for, and in many cases will be used for both.<\/p>\n

For example, consider my implementation of DoesNotExist<\/code>:<\/p>\n

\n
class<\/span> DoesNotExist(<\/span>Condition)<\/span>:
\ndef<\/span> __call__<\/span>(<\/span>self<\/span>,<\/span> state)<\/span>:
\nreturn<\/span> TESTKEY not<\/span> in<\/span> state<\/div>\n<\/div>\n

Effect<\/h4>\n

An Effect<\/code> changes our view of the state (and depending on the driver, may actually cause something in the world to change with it). For example, the StoreEffect<\/code> works as follows:<\/p>\n

\n
class<\/span> StoreEffect(<\/span>Effect)<\/span>:
\ndef<\/span> __call__<\/span>(<\/span>self<\/span>,<\/span> state)<\/span>:
\nstate[<\/span>TESTKEY]<\/span> =<\/span> ‘0’<\/span><\/div>\n<\/div>\n

Action<\/h4>\n

An Action<\/code> brings an Effect<\/code> and one or more Condition<\/code> classes as pre and post conditions. For example, we\u2019ll look at two actions, an Add<\/code> action and a Set<\/code> action:<\/p>\n

\n
\n

class Set(Action):
\neffect = StoreEffect()
\npostconditions = [Exists()]<\/p>\n

class Add(Action):
\npreconditions = [DoesNotExist()]
\neffect = StoreEffect()
\npostconditions = [Exists()]<\/p>\n<\/div>\n<\/div>\n

The interesting part of this is that Set and Add have different semantics, but are expressed as different compositions of the same conditions and effects.<\/p>\n

Driver<\/h4>\n

Driver is kind of a larger part (seven defined methods!). It does enough that I can do anything from generate a C test suite for memcached engines all the way to actually executing tests across a remote protocol.<\/p>\n

I won\u2019t describe the entire thing here since it\u2019s documented in the source<\/a>. I will however, close the loop by showing you some example code that it generated that demonstrated the error we failed to find in the first place:<\/p>\n

\n
static enum test_result test_add_add_delay_add(<\/span>ENGINE_HANDLE *h,<\/span>
\nENGINE_HANDLE_V1 *h1)<\/span> {<\/span>
\nadd(<\/span>h,<\/span> h1)<\/span>;<\/span>
\nassertHasNoError(<\/span>)<\/span>;<\/span> \/\/ value is<\/span> “0”<\/span>
\nadd(<\/span>h,<\/span> h1)<\/span>;<\/span>
\nassertHasError(<\/span>)<\/span>;<\/span> \/\/ value is<\/span> “0”<\/span>
\ndelay(<\/span>expiry+<<\/span>span class<\/span>=<\/span>“mi”<\/span>><\/span>1<\/span>)<\/span>;<\/span>
\nassertHasNoError(<\/span>)<\/span>;<\/span> \/\/ value is<\/span> not<\/span> defined
\nadd(<\/span>h,<\/span> h1)<\/span>;<\/span>
\nassertHasNoError(<\/span>)<\/span>;<\/span> \/\/ value is<\/span> “0”<\/span>
\ncheckValue(<\/span>h,<\/span> h1,<\/span> “0”<\/span>)<\/span>;<\/span>
\nreturn<\/span> SUCCESS;<\/span>
\n}<\/span>
\n<<\/span>\/span><\/span><\/div>\n<\/div>\n

That demonstrates how much information you know at each step of the way. From there, we can do all kinds of stuff with our stubs (delay above is implemented with the memcached testapp \u201ctime travel\u201d feature, for example).<\/p>\n

From here, it\u2019s less exciting. We provide constraints, it writes tests, and makes sure that there\u2019s another area that it\u2019s impossible for users to encounter something we haven\u2019t seen before.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
