Why should I outsource quality assurance?

Quality assurance outsourcing goes beyond simply testing a software application or product. This holistic approach helps QA engineers ensure that all features work smoothly and that the developed solution is free of bugs.

It might become a cost-effective choice for your software development project. If you are on a budget but lack a qualified team to perform testing for your software product, outsourcing can completely meet your needs without compromising quality.

What are the quality assurance and testing stages?

Our testing process includes the next stages:

  1. Quality and UX audit
    At this stage, our QA experts scrutinize the UI of your product and come up with thoughts on how to make your user experience smoother and more enjoyable.
  2. Performance Evaluation
    We examine the performance of your application in different environments and check on its scalability and stability under additional user loads.
  3. Security and Compliance tests
    We find and fix threats and vulnerabilities in your system to wipe out all possible security risks.
  4. Code Review
    During this stage, we inspect the quality and consistency of your code and provide recommendations on what should be changed or improved.
  5. Software Validation
    Validation testing crops up at the end of the development process to ensure that the end product meets the conditions and performs all the necessary functions.
  6. Software Maintenance
    When your product is deployed, you need to keep its performance high. During this stage, we test all the changes in your product to sustain its quality and capacity for stable work.
