TA: How to get the Session Storage data from your browser

Our test automation suite for a single page application (SPA) called service-hub, takes almost one hour to run all +- 200 scenario's in serie per browser. The amount of scenario's will keep on growing with the expansion of the product. So I needed to start using some clever tricks to speed up the process. One of those tricks is by testing in parallel sessions. This is a very good thing to figure out anyway, but is also taking more resources (and therefore cost more money). Another trick is by using the API for some of the preconditions that take a lot of time. But for that we need a token which is stored in the browsers Session Storage.

Scenario example

For the service-hub product which I'm testing, it takes precious time to add/remove a material from an activity if I need to do this all via the UI. There are many steps to take to make sure I'm on the correct page, tab, breadcrumb, sub-tab and finally the element and to cover all other scenario's that might be failing from other tests that can block any user interaction. Most of the steps I need to perform anyway, but I can make it faster by checking via the API if a material is already in the list and based on the precondition remove or add it before moving on. 

Session Storage

For the API I need a bearer token to be able to perform GET/POST actions. So after I'm a logged in user, I want to extract the bearer token from the browser so I can use the API for some preconditions. And it's easier than I thought.
So with that in place, I can now use this to add materials to the activity like this:
asset_id_1 = "b15940c5-3165-4cb5-a1f7-02dceeab86f0" asset_id_2 = "aaaaaaaa-1111-a1a1-b2b2-000000000000" asset_id_array = [asset_id_1, asset_id_2]
activity_id = "501206de-c88d-4108-9fc7-392c90a962de"
token = Token.get_access_token #Get the access token, for the header (see below)
url = "<base_url>/Activities/Default.AddMaterials"
payload = { "AddMaterialsCommand":{ "ActivityId":activity_id, "AssetsId":asset_id_array } }
headers = { "Authorization" => "Bearer #{token}", "Content-Type" => "application/json" }

 # With the 'rest-client' gem we can now execute this command to add the materials to the activity
RestClient.post(url, payload.to_json, headers=headers)

PowerShell - How to overcome Azure VM's fixed resolution limitation

Image
Intro This is the first in a series of PowerShell blogposts. I don't know a lot of PowerShell so I'm going to cover this part very short. What is PowerShell? PowerShell is a very powerful framework you can use to automate tasks. For more info, use Google or check the Wiki:  https://en.wikipedia.org/wiki/PowerShell For my current project we use Azure VM's that we use as selenium-grid (hub and nodes). And Visual Studio Online for kicking off builds. So I started to use a fair share of PowerShell in my test automation process. During the setup I came accross a couple of problems that I want to share with you all which I'll spread across a couple of posts. And we start with Azure VM's that have a fixed resolution of 1024 x 768 and how to overcome this issue/limitation. Azure VM's resolution limitation  Let's start with the problem we faced. Our website under test, requires the test machine to have at least a certain resolution ( Which is > 1024

TA Basics: Website Test Automation on mobile devices via Appium server

Image
Recently I have been focussing on test automation with mobile devices. Specifically Android and iOS (no Windows phone because that platform is as good as dead at the moment). I first wanted to make a complete manual from setting up software and devices/simulators up to a small test script. But due to lack of time I'll focus on specific parts. If you have any questions reguarding the setup, feel free to contact me. So all that said, let's get to the point. The internet is full of blogposts, video's and examples of people testing mobile apps. However I don't test an app, I want to do some web test automation on mobile devices. It took me quiet some time to figure out what exactly I had to use to get it all to work as needed for my project. Setup Mac mini running OSX 10.13.4 High Sierra (Mac machine is needed for iOS simulation) Ruby version 2.5.0p0 (2017-12-25 revision 61468) [x86_64-darwin17] Appium desktop version 1.4.1 (with Appium server 1.7.2) lapis_laz

TA: Who doesn't like proxies? Me!

Image
Are you on a company network that is using a proxy to connect to the internet? And do you want (or are you planning) to connect your tests to an external selenium-grid. Than stay tuned, before you get lost in a bunch of answers on the internet that don't resolve the issue you're facing. Source:  https://nl.wikipedia.org/wiki/Proxyserver I'm on a new project and looking into Robotframework. But then I bumped into an issue with the POC I had to make which might result in me convincing the company to switch to Ruby. Anyway long story short. They use a proxy and although the internet has all the answers, you do need to know what specific question to ask to get the correct result. And since proxies are not used that much anymore, it's hard to find the skilled people to help you out and push you in the right direction for a solution. The setup To access the internet, I need a configuration on my computer that will tell Windows to connect to a proxy server. I
