Types of testing
Types of testing
A professional QA-team consisting of Invento Labs specialists will analyze the challenge you are faced with and offer the best combination of various types of testing based on your needs and objectives.
Functional testing

Functional testing. It focuses on the expected functionality of the application under test. It answers the basic question: Does the application perform the functions declared in its specification?

  • Alpha testing is testing at the development phase, prior to product finalization.
  • Beta or acceptance testing includes checking the compliance of the system with the requirements and acceptance criteria.
  • Black Box testing is testing without access to the code.
  • End-to-End testing verifies that the system meets its purpose from the user’s perspective. For best results, end-to-end testing is performed in an environment as close as possible to the anticipated production environment.
  • Exploratory testing is the simultaneous design and performance of functional tests.
  • Modular testing is the testing of individual modules of the future system (application) without any connection with each other.
  • System testing checks the behaviour of the entire system in accordance with business, system and functional requirements. This is usually done after the completion of modular testing and integration testing.
  • Regression testing verifies that any modification has only had positive outcomes and that the application still meets the requirements.
  • Smoke testing is testing based on business scenarios, aimed at checking the performance and readiness of the developed product for more advanced testing, determining the overall quality status of the product. This type of testing allows you to initially identify the main critical defects that are quickly detected. Unless the performance test is passed, integration is rejected.
Non-functional testing

Non-functional testing involves diving deeper into the system deeper than during functional testing and testing of properties that are not related to the functionality of the system

  • Localization testing verifies the quality of localization (translation into different languages) of interface elements, system messages, reference information and other materials. During localization testing, translations are created, applied and tested.
  • Usability testing is aimed at identifying problems related to software usability and offering recommendations for improving the UI.
  • Big Data Testing.
Mobile app testing

Functional testing

  • Functional testing ensures that the application meets the requirements.
  • Laboratory testing verifies voice or data communication.
  • Interrupt testing checks whether the app function can recover from interruptions such as network failures, text messages or incoming calls.

Non-functional testing

  • Performance testing verifies app behaviour under certain conditions, such as low battery, poor coverage or low available memory capacity
  • Memory leaks testing checks memory allocation
  • Usability testing verifies ease of use for the end user
  • Installation testing ensures that the installation process has gone smoothly.
