Installation
How do I analyze?
Let's pretend that you have a large web application, and are in the process of changing the way you verify user permissions when accessing a page.
That's it! The run
method of Experiment
will always return the result from your control. Both your control and
your candidate will be run, and Analyst will record what happened to both blocks of code. In the next section, we'll
take a look at what you can do with that information.
Publishing Experiment Results
Testing multiple code paths is pretty useless if we don't do anything with the information we get from our experiment.
That's where publishing comes into play. All you need to do is implement that publish
method in a custom Experiment
class.
Now, if we were to rewrite our earlier user permission example to use our custom MyExperiment
class, it would look
like this.
In the above example, we created our own Experiment
implementation, named MyExperiment
. In it, we made sure we had
a database connection (using PHP's PDO
class), and wrote data to it using the publish
method. Then, when we ran
our experiment within our controller example, all we needed to do was provide the extra arguments to the create
static
method of MyExperiment
(which we implemented ourselves to allow for the additional constructor argument).
After every experiment is run, Analyst will always call the publish
method of the experiment used to do our analysis.
Our options aren't limited to simple database inserts. You might decide to log the data to a file using a library like
Monolog, or you might send it off to a cloud service. It's up to you!
