Our Services

Software Testing Types We Perform

Bestarion provides comprehensive software testing services for every challenge. We offer various types of testing and create custom quality assurance management plans to ensure your team delivers the highest-quality version of your product with speed and precision. We can support your platforms as they continue to evolve.

Manual Testing

Manual testing typically applied to smaller builds and systems requiring frequent feature changes, enables our team to identify vulnerabilities in your software that can’t be detected automatically. It also helps us better understand your application’s flow and is a base for the consequent automation testing.

Automation Testing

Using trusted automation frameworks, we can help you accelerate releases, increase test coverage and find more bugs before they enter production. Bestarion’s automated testing services enable organizations to check every aspect of the app’s performance and quickly identify invalid functionality, architectural flaws, vulnerabilities, scalability issues, and even design mistakes.

Our Services

Agile Software Testing Process

We employ the agile testing approach, a new-age approach focusing on testing smarter rather than putting in a lot of effort yet delivering high-quality products. Agile testing speeds up the detection of defects and reduces the cost of bugs by fixing them early. This approach also yields a customer-centric approach by delivering a high-quality product as early as possible. We are also proficient in setting up continuous testing practices and integrating testing activities into CI/CD pipelines within the DevOps approach.

Frequently asked questions

If you're new or looking for answers to your questions, this guide will help you learn more about our services and their features.


Software testing is a systematic evaluation of a product’s quality. Its purpose is to verify that digital products work as intended. For this, QA engineers interact with a program, application, etc., aiming to identify errors, gaps, or discrepancies between its expected and actual behaviors.

During testing, specialists assess different aspects of the software: functionality, performance, security, usability, and compatibility. Testing services for software highlight defects early in the development cycle and fix them before the software is released and becomes available to end-users.


By testing software, QA engineers ensure that a product meets user requirements, performs optimally, and is free of critical errors. If not, finding and fixing the problems enhances the software’s quality and reliability.

In particular, software testing as a service:

  • Helps identify, fix, and prevent defects from escalating into more significant problems during later stages or after deployment.
  • Ensures that the software meets business and system requirements and other compliance and quality standards.
  • Contributes to a positive user experience and higher loyalty by addressing issues that could impact functionality, performance, or usability.
  • Plays a vital role in risk mitigation strategy, reducing the likelihood of project delays or failures.
  • Allows for minimizing software development and maintenance costs by addressing defects early on.
  • Analyses the software’s performance under different conditions, including heavy user loads or varying network speeds, to optimize performance for different scenarios.
  • Provides valuable feedback regarding product enhancements, updates, and future iterations.

Testing strongly contributes to the overall success of software projects. Hence, outsourcing software testing services will help you launch high-quality, reliable, and user-friendly products and services.


Software testing and QA (Quality Assurance) services are related to the software development process, but they are different in their goals and focus.

Software testing refers to the process of checking the software application or system to ensure that it works as intended and that it meets the specified requirements. It involves executing the software with different test scenarios and data to identify any defects, errors, or issues that may affect its performance or functionality. Testing can be manual or automated and can include different types of testing such as functional testing, performance testing, security testing, and usability testing.

QA services, on the other hand, encompass a broader range of activities that are designed to ensure that the software development process produces high-quality software that meets the user’s needs and expectations. QA services are concerned with the entire software development life cycle, from requirements gathering and design to coding, testing, and deployment. QA services include activities such as creating quality standards and guidelines, conducting reviews and inspections, performing testing, managing defects and issues, and ensuring compliance with relevant regulations and standards.

In essence, software testing is a specific activity within the broader scope of QA services. Testing focuses on verifying that the software works as intended, while QA services focus on ensuring that the software development process produces high-quality software that meets the user’s needs and expectations.


We always make sure to find at least several common hours. You can be sure you can communicate with QA engineers directly during your working day. If you want to involve QA engineers in the team meetings, it won’t be a problem at all.

Meanwhile, the time difference has its perks for outsourcing software testing services. Namely, when your team has off-work hours, we’re testing. Your teams can see the results, receive reports and tickets, and get something to work with first thing in the morning.


Bestarion is a leading provider of end-to-end software testing services, leveraging global expertise and advanced automation tools to ensure quality, reduced time to market, and optimized costs. Together, we can accelerate digital transformation with reliable and scalable software testing services.

There are many different types of software testing, which can be broadly categorized into the following types:

  • Functional Testing: This type of testing checks if the software application or system works as intended and meets the functional requirements.
  • Performance Testing: This type of testing checks the software’s performance in terms of speed, scalability, and stability.
  • Security Testing: This type of testing checks the software’s security features and identifies any vulnerabilities or threats that could be exploited.
  • Usability Testing: This type of testing checks the software’s user interface and user experience to ensure that it is user-friendly and easy to use.
  • Compatibility Testing: This type of testing checks the software’s compatibility with different operating systems, hardware, and software configurations.
  • Regression Testing: This type of testing checks if changes or updates made to the software do not affect the existing functionality or create new defects.
  • Acceptance Testing: This type of testing checks if the software meets the user’s expectations and requirements.
  • Integration Testing: This type of testing checks the interaction between different modules or components of the software system.
  • Exploratory Testing: This type of testing involves exploring the software application or system to discover defects or issues that were not identified in other testing types. Automated Testing: This type of testing uses automation tools to execute tests and verify the software’s functionality, performance, and security.
