AtoZ has hundreds of years of combined experience in software testing and quality assurance. We have structured our extensive expertise in the following ways:

Defining the requirements

A successful and high-quality software project begins with working closely with the client to define the software’s functional and non-functional requirements, as well as understanding how users will interact with the software. Once a shared understanding and assessment are achieved, the requirements are written as use cases and user stories, which define how the software will be used. In agile development, requirements can be prioritized based on their value to the business, with development starting on the features that offer the greatest business value. This forms the foundation for the software testing plan and the actual testing work.

Reviews
The tester’s work should begin with reviewing the requirements and user stories, as this helps the tester gain a deeper understanding of the software, plan the testing strategy, and identify potential areas for errors. Early identification of flawed requirements can prevent them from being incorporated into features and functionalities. The business goals are reviewed with the client, and the necessary documents are examined, assessed, and reported as agreed.

Test Packages

We begin with a 2-hour kickoff meeting with the client to review the system’s current state and set the development goals and targets. Technical challenges are refined based on business objectives, which then drive the testing. After tests are completed, results are reported to the client, along with concrete recommendations for corrective actions. Pricing is based on a fixed 2-week period.

Testing Process Auditing and Improvement
We work with the client to assess the current testing functions, identify, describe, and define the process's current state, and set the desired future state. Based on observations, issues are identified and delimited, with recommendations for improvements in the current processes. If necessary, a new testing process and best practices are proposed. Metrics are developed to measure the efficiency of the testing process.

Test Automation
We review the current testing functions and practices with the client and plan how test automation can be leveraged to ensure the quality of business-critical software and applications. Parts of the system suitable for test automation are identified, and necessary resources and tools are suggested.

Acceptance Testing
We work with the client to review business objectives and requirements related to use cases that the system must fulfill before deployment. The system’s usability, quality, readiness, and performance are verified through test cases executed manually from the user’s perspective, using the client’s own data. Acceptance testing also considers integrations between different systems and components. If possible, the testing is performed in close collaboration with the client. Based on the test results and feedback, software improvements are recommended if the results deviate from the defined requirements.

Performance Testing
Performance testing design involves reviewing the client’s non-functional requirements, such as accessibility, usability, or scalability. Data volume limits and user count targets are refined into test cases, which are executed on the client’s test environment. Based on the results, software improvement recommendations are provided to the client.

Security Testing
To ensure business continuity and identify privacy risks and threats, security testing is performed by scanning the client’s systems for vulnerabilities, using OWASP TOP 10, OWASP ASVS, and other standard tests. Results are reviewed with the client, along with suggestions for improvement to enhance security.

Exploratory Testing
We review the business goals related to costs, timelines, and software features with the client. If there is a need to save on resources and testing time is limited, exploratory testing can be used to test user stories without complex preparation.
Repeating the same tests reduces the likelihood of finding new defects, but through exploratory testing, new issues can be discovered by trying new things in new ways based on previous experience. If resources and time are limited, exploratory testing offers a more cost-effective alternative to traditional testing. It is especially useful in Agile software development projects, where testing can be done simultaneously with development to quickly gain insights into the software’s status. The tester learns about the software and plans how and what to test based on the test results.

In DevOps environments, exploratory testing can also be done in production environments, allowing for testing during the release process and investigating client issues in collaboration with DevOps teams.

Accessibility Testing
Based on client needs, we ensure the accessibility, usability, and availability of digital services. The accessibility of applications is tested across multiple browsers and devices. Through search engine optimization, websites are optimized to rank higher in search results, attracting visitors to return.

Visual and cognitive accessibility testing involves designing the user interface to be visually perceptible for the user. Navigation should be intuitive and easy to manage, and the interface must function reliably, allowing for integration with assistive technologies.

MVP and PoC
Together with the client, we create a plan to ensure the core functionalities and user interface quality of a desired solution through exploratory testing. Based on user stories, fundamental errors, deficiencies, and bottlenecks can be identified early in the process, avoiding them before development begins. After exploratory testing, automation testing is introduced to handle the core functionality testing as product development continues.
