Types of QA Testing
Types of QA Testing

Invento Labs’ team of QA professionals will analyze your problem and offer the optimal combination of various types of testing suitable for your needs and tasks.

Functional testing

This type of testing focuses on the expected functionality of the tested application. It answers the main question: does the application fulfill the functions stated in the specification?

  • Alpha testing - testing carried out at the development stage, prior to the product finalization.
  • Beta testing or Acceptance testing – examination of whether the system meets the requirements and acceptance criteria.
  • Black Box testing - testing without access to the code.
  • End-to-End Testing - the goal of end-to-end testing is to verify that the system fits its purpose from the user's perspective.
  • Exploratory testing - represents the simultaneous design and execution of functional tests.
  • Modular testing - testing of individual modules of the future system (application) without their connection to one another.
  • System testing – examination of whether the behaviour of the entire system complies with business, system, and functional requirements. It’s usually done after the completion of modular testing and integration testing.
  • Regression testing – examination to ensure that any modifications implemented had only positive outcomes and that the application still meets the requirements.
  • Smoke testing - 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.
Non-functional testing

This type of testing requires diving deep into the system than in functional testing, specifically aimed at testing the features that are not related to the functionality of the system.

  • Performance testing is a set of various types of testing, the purpose of which is to determine the operability, stability, resource consumption, and other attributes influencing the quality of your software under various scenarios of its use and workloads.
  • Usability testing – the identification of issues related to the software usability and UI improvement recommendations.
  • Database testing (Big Data testing) – examination of data integrity and search for opportunities to optimize database queries.
Mobile App testing

Invento Labs carries out the web, hybrid, native, and client-server application testing. We form a set of devices and versions of operating systems necessary for testing according to the Client's task.

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.
