How we test
Functional testing
We check if an application works correctly based on the requirements.
Usability testing
We assess if an app is convenient, user-friendly, and easy-to-use.
UI testing
We validate the proper display and work of the graphic user interface (GUI) elements in an app.
Integration and API testing
We test integration between different modules of an app and between an app and third-party solutions (at this stage we thoroughly check APIs).
Performance testing
We test the app's speed, reaction to load from many simultaneous users and requests, and other performance aspects.
Compatibility testing
We check how an app works on different devices / browsers and its synchronization between devices / other platforms.
Security testing
We assess an app’s security level by following the OWASP criteria and methodology.
Regression testing
We check if fixing the discovered bugs caused any negative effect on the existing features and functionality of an app.
Stages of testing
QA during different SDLC stages
Requirements analysis stage
- analyzing and forecasting risks
- preventing errors in functional and non-functional requirements
- preparing a high-level test plan
- determining the necessary types of testing
- developing test methodology
Design stage
- analyzing the time needed for testing
- confirming that the architecture satisfies all non-functional requirements
- analyzing / preparing a data flow diagram and documentation for it
- verifying entity relationship and workflow process diagrams + user stories
- verifying compliance of the specification with design layouts and UIs
- preparing a low-level test plan
Development stage
- QA procedures for the finished prototype
- unit testing
- creating a list of test cases
- designing Behavior Driven Development cases
- preparing the test environment
Testing stage
- preparing test documentation
- designing metrics to cover functional requirements with tests
- conducting comprehensive product testing
- testing non-functional requirements
- confirming that all discovered bugs were verified and fixed
- participating in UAT testing
- preparing the final test report
Implementation and post-production stage
- preparing a manual with user cases and user stories
- preparing a report with risks analysis, missed requirements / defects, and suggestions on quality improvements
- analyzing and forecasting risks
