Dev Dives: Streamline document processing with UiPath Studio Web
Cerberus : Framework for Manual and Automated Testing (Web Application)
1.
2. What is it ?
Web Application .
Developed by La Redoute since 2011, then published in Open source.
Source code and documentation available on github and sourceforge :
https://github.com/vertigo17/Cerberus
Almost 2600 commits by 10 contributeurs
Centralized test repository.
Automate multi-technologies.
(Web, Application Mobile, Heavy Client, SOAP, Rest, SQL…)
Multi-environment (DEV, QA, UAT, PROD….)
Multi-langages (FR, UK, RU, IT, PL, …)
3. Business
Development
Team
Test Team
Where does it come from ?
• From the observation of the limits of a traditional organization.
• Silo Organisation.
• Test definition during or after development phase.
The possible interpretation of a functional specification
can lead to a number of significant go back .
The test case, correctly described in earlier in the
development phase , is the most effective way to
prevent the poor quality .
Need for a common test repository to the various players , fed earlier in the development phase.
4. Where does it come from ?
• From the experimentation of new organizations : Agile / Continuous Integration / Devops
time
risk
timeShort iteration
Long iteration
Need for test automation
No automated Tests = No quick feedback = No short iteration = Increasing risk to production deploy.
Regression risk evolution vs delay between each deploy
DevOps is an effort to create business value by involving all
stakeholders in the software development ( from design to
production , including the developers ) through short iterations
and recognize the value closely , consists of experimentation and
rewind.
5. Where does it come from ?
• From the experience in test automation.
To guarantee test maintenability.
a.Avoid code duplication
Use step library.
b.Guaranty functional test coverage.
Functional test coverage should be defined by business/MOA team.
c. Deploy one unique repository.
Link functional information with technical implementation to allow to easily maintain one unique repository.
Need for a test framework, including functional and technical information.
6. Test Automation
Web (Selenium)
IOS and Android Apps (Appium)
Heavy Client / GUI (sikuli)
Web-services (xml unit)
Databases (sql connectors - jdbc)
Why do it ?
• A common test repository to the various players , fed earlier in the development phase.
• Test automation whatever the technology.
• Test framework, including functional and technical information.
Test Repository
Functional description ACTION / CONTROLES / DATA
Test centralisation
Step library
Test description standardisation.
Testing Management
Testcase execution Dashboard.
Performance metrics.
Log (screenshot).
Standardize test reporting.
Link to ticketing system.
9. Cerberus usage : in the context of the project
1 –Test specification allowing to guaranty the quality of the project
• Who ?
Business, AMOA.
• Where ?
In the description fields.
• How ?
Following the frame (Action/Control).
Using step library and data library.
• When?
As soon as possible in the project.
Ideally during functional specification.
10. Cerberus usage : in the context of the project
2 –Test Automation
• Who ?
Developers, QATeam.
• Where ?
In the script fields.
• How ?
Following the frame.
• When?
During development phase.
When user interface are designed.
11. Cerberus usage : in the context of the project
3 –Test Execution
• Who ?
All project actors.
• Where ?
Manual & Automated. In the test execution page.
• How ?
Manual: Allow to define status for each action.
Automated : Launched manually or for continuous integration chain.
• When ?
During the test phase.
Manual execution
12. Cerberus usage : in the context of the project
4 –Test project management
• Who?
Every project actors.
• Where ?
Reporting page
• How ?
Follow execution status.
Interface with several ticketing tools.
• When?
During the test phase.
13. Cerberus usage : in the context of the project
Synthesis:
Test specification.
• Suivant le cadre défini (Data/Actions/Contrôles)
• En utilisant les données et étapes de libraires
Test automation (20/80)
• Pour le périmètre qui n’est pas en librairie / données

14. RegressionTesting : key figures
La Redoute :
For the perimeter www.laredoute.xx (10 countries) and m.laredoute.xx (10 countries) :
3500 tests launched twice a day (UAT and PreProd).
4 production deploy for each application.
Speed of test creation increasing, due to library usage.
Evolution du périmètre des TNRs
Aout 2014

Aout 2015
2000 Tests
Janvier 2016
2900 Tests
Avril 2016
3500 Tests
16. Functional monitoring
Run functional to guaranty .
Functional test execution
(Example : 10 scenarii every 5 minutes)
Technical data records
• Response time per action
• Network Trafic (HAR file)
Data exploitation
• Services allowing to raise alert on
non OK status.
• Publish data into Elastic Search
/Kibana
• Business Activity Monitoring
17. Functional monitoring : key figures
Follow the availability of the key scenarios:
Homepage / Authenticate / Account creation / Navigation / Product List / Product Page / Comparison / Basket /
Delivery / Payment
At a pertinent frequency:
Every 5 minutes, 21h a day
>> 24.000.000 step every year for1 application
Decorelate the cost of the monitoring from the execution frequancy allow to avoid to opposite
quality with cost of the necessary solution.
19. Cerberus in an InformationTechnology service
Cerberus can be interfaced with a lot of popular tools already in place in most of the IT service
Oracle SQL
MySQL
PostGreSQL
DB2
Microsoft SQLServer
SSAS
Can be launched by any task scheduler.
• Via 1 api REST
• $U, cron, Jenkins….
• Execute 1 test or even a campaign
Push execution status.
• OK/KO for a go/no go status
Push into ES/Kibana
Automatic ticket opening.
• In Mantis / Redmine / ….
• Forward testcase information
Can be intefaced with Centreon
Allow to Read/Write any Database.
