Manual QA Testing

Manual testing is one of the most successful testing approaches for finding severe bugs. This is because it leverages techniques like logical reasoning and inferences to discover some of the issues that automation testing sometimes ignores.

Why Quality Assurance Manual Testing

Manual software testing is still essential even in the age of total automatization. Being a very basic type of testing method helps find the bugs in the application.

Our quality assurance manual testing detects severe bugs by designing and passing atypical test cases drawing on our wide experience with testing solutions for different industries. Our QA engineers are always aware of new technologies and approaches to make sure your product is tested very thoroughly.

With our manual testing services, we ensure the flawlessness of your application by finding both visible and hidden defects which can affect user experience and the usability of the software. 

To benefit from the advantages of manual testing over automation and to make testing activities as effective as possible, VT Labs manual testers:

  • test from the end-user’s perspective

  • take into account previous user experience

  • possess cognitive abilities

  • consider risk assessment

  • constantly communicate with developers and project stakeholders

  • test beyond requirements
