Performance tests
Gatling - Java

The training is aimed at testers and QA. In order to make the most of participation in the training, we require basic knowledge of object-oriented programming (preferably Java), understanding of Rest API communication and the basics of building Web applications. If you have doubts whether the training is for you, write to us at kontakt@cantest.it. We will be happy to answer any questions.

In order for the training to run smoothly, we require:
​

• software testing experience

• knowledge of the basics of object-oriented programming (preferably Java)

• understanding Rest API  communications

• understanding the basics of building web applications

​
If you are wondering if you can handle the training, write to us at kontakt@cantest.it. We will be happy to talk, advise and dispel your doubts.

I Theory and Fundamentals
​
• Definition of performance tests
• Types of performance tests
• Risks related to late detection of performance errors
• What should be measured in performance testing?
• Performance testing methodology and setup
• Percentile and other concepts in statistics
 
2. Application setup
​
• Launching the project
• Overview of the tested architecture (Application written in Java with
using Spring Boot, which provides the tested REST API)
• Launching the project with tests
 
III Practice - workshop writing tests in Gatling and Java
 
• Refactoring of the startup script. Gatling for easier maintenance
seeing and understanding objects
• Work with static test data in *.json or *csv format
• Generate random test data via code
• Saving and reusing values from HTTP responses (e.g. Token
JWT)
• Build requests using easy-to-maintain domain objects
(DTO)
• Traffic profiling
• Cleaning of test data using less frequently used Gatling methods
 
IV Theory - advanced
​
• Defining requirements
• Functional and non-functional assertions
• Load balancer - its importance for performance tests
• SLIs, SLAs, SLOs
• Introduction of a clear and understandable performance metric, reporting
for business and management
