Informations about the package yii2-abtest
yii2-abtest
A simple extension for writing A/B Tests in Yii2.
This extension does not include the hooks for various programs, but does allow you to list()
so you can quickly
add it to your analytics code.
Installing
Simply include it from composer:
php ./composer.phar require sammaye/yii2-abtest:"@stable"
Adding it to your configuration
Easiest thing is to just show an example of my configuration:
'test' => [
'class' => 'sammaye\abtest\Test',
'filter' => [
'rules' => [
[
'allow' => false,
'roles' => ['staff']
]
]
],
'tests' => [
[
'name' => 'Beta Search',
'values' => ['old', 'new'],
'default' => 'new'
]
]
],
The configuration breaks down into two parameters:- filter
and tests
.
Only tests
is required.
filter
allows you to use the AccessControl
like you would on any controller and
provide a set of rules whereby the tests should not take effect.
When an 'allow' => false
filter is matched the test will return the default
parameter from the test you are looking at
and will not not record it in $_SESSION
.
This way, when you come to list()
at the end of the page to push onwards for analytics, these tests will not appear in that list.
Using it
Once it is fully configured you can just use it to detect which path a user takes:
Yii::$app->test->value('Beta Search')
This function will return either old
or new
depending on whether I am a staff member or lady random chooses me.
In order to add it to your analytics code you need to list all active tests and their values:
Yii::$app->test->list()
This will then print out a list of (for me):
[
'Old Search' => [
'name' => 'Old Search',
'value' => 'old' // active
// custom data could be housed
// here from the configuration like "goal"
]
]
So, the key is name of the test and the value is the configuration object but with values
replaced with only the active value
.
