At the highest level, the software testing process consists of functional and non-functional aspects alongside automated and manual testing services. Non-functional testing relates to the way the system operates from a business perspective, rather than its specific functionality. Aspects like capacity, reliability, availability, scalability, recovery, and integrity are types of non-functional testing. Functional software testing services involve tests like unit testing, user acceptance, integration testing on different SDLC stages according to prior plans, checklists, and scenarios for testing.
Unit tests, integration testing, end-to-end testing, smoke, sanity, regression testing, acceptance and white box testing, sanity, and so on, are distinct software testing types. The QA engineer can apply manual and automation software testing services using various tools like JMeter, Selenium, Swagger, etc.
There is also UAT, which stands for User Acceptance Testing, as a distinct service in software QA outsourcing. Within the UAT phase, the product owner and/or real users check product compliance with the real-world needs, scenarios, requirements, etc. This is a sort of beta testing before the software’s release to ensure the ultimate service performance.
