I want to improve the Virtual User (VU) I created in my previous blog<\/a> by adding dynamic browsing of the shop web site. Indeed, as VU is based on a HAR file, it is statically browsing the website. Thus, if the website is evolving like a new species is added, the VU will never browse to it. For now, it is always going into “Fish” category and add a “Koi” to the cart. This is not really simulating real customer behavior (randomness either, but it is better \ud83d\ude09 ). That’s why, I will explain you here how to add some randomness in the browsing to be more dynamic.<\/p>\n\n\n\n

Extracting Information<\/h2>\n\n\n\n

First thing, I must do is to get all links to every category of the shop from page body.<\/p>\n\n\n\n

To do that, I will add a “Regexp extractor”:<\/p>\n\n\n\n

\"\"<\/p>\n\n\n\n

Then, we must fill in few information to it:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The most important field is “expression”. It is a regular expression<\/a> that will be used to find and extract matching patterns. Fortunately, OctoPerf is providing a tool to build it more easily. A click on the gear will open the recorded content and I will be able to find object I want to focus on (i.e. all species URLs):<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

In that window, I can search for any string. Let’s look for “Fish”:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Here, we can see the 5 existing species. If I select the part I am interested in (i.e. categoryId), it will automatically create a simple regexp for me:<\/p>\n\n\n\n

ory=&amp;categoryId=(.+?)\"<\/code><\/pre>\n\n\n\n
Another nice feature of OctoPerf is the ability to test this regular expression against the recorded content, so let’s try it (I am selecting All in Match Number option).<\/p>\n\n\n\n
With this new regexp, the list of extracted variables looks like the following:<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
You see there are duplicated results as links are present twice in the web page. As I will select Random option in “Match Number” parameter, it will be fine as it does not change category distribution (all categories are doubled).<\/p>\n\n\n\n
Using Variable<\/h2>\n\n\n\n
Now that we have the variable, let’s use it in the GET query that list all items in a category. The URL is currently containing a hard coded value: “FISH”:<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
I will empty the field and type “${“, then OctoPerf will suggest possible values including variables:<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Extracting Product<\/h2>\n\n\n\n
The next step is quite similar to previous, but as we are getting better, I will a bit faster.<\/p>\n\n\n\n
    \n
  1. Create a new RexExp Extractor under the GET action<\/li>\n\n\n\n
  2. Click on the gear to find the list of productId’s<\/li>\n\n\n\n
  3. Select the interesting text to get regexp generated: duct=&productId=(.+?)\"<\/code><\/li>\n\n\n\n
  4. Click Save and Debug to confirm it is working:<\/li>\n<\/ol>\n\n\n\n
    \"\"<\/figure>\n\n\n\n
    Note that result might differ as the categoryId is selected randomly.<\/p>\n\n\n\n
    Next, we need to modify the GET action on the productId to be dynamic as well:<\/p>\n\n\n\n
    \"\"<\/figure>\n\n\n\n
    GET action inside 04 – Add to Cart<\/em> container must be modified as well.<\/p>\n\n\n\n
    Run<\/h2>\n\n\n\n
    Finally, I will run the VU to check how it behaves and ensure I did not forget anything.<\/p>\n\n\n\n
    With these changes, the VU will work even if shop is adding or removing any species in the catalog as variables are dynamically extracted from web pages. <\/p>\n","protected":false},"excerpt":{"rendered":"
