Quality Assurance Services

Functional Testing

Functional Testing (manual, semi-automated and automated) for all types of software ensures that your software and its components function correctly and conform to your requirements, business processes and the overall software business logic. This can involve testing of valid and invalid user actions, environment-specific behavior, APIs, product/user interface, database management, links, security, installation, networking, prototype, and much more.

Latitude's functionality testing service for live products empowers our clients to add value to their systems without the threat of damaging a live application. This service is also used as an acceptance check for the work of a third-party company.

At the end of the test cycle, you will receive assessment reports detailing test results and professional observations, along with relevant recommendations as to strategies to improve the application's overall quality.

Functional testing is especially effective when run iteratively and simultaneously with development of the application. Bugs found after release into production can be significantly more costly than errors found early in the software development process.

Performance and Stress Testing

Typically used to diagnose the performance and stability of software under normal and extreme operating conditions. As a result, you can identify the areas of your solution that requires tuning prior to deployment.

PST testing should also be employed to evaluate the maximum number of concurrent users, report rendering speed, data access, traffic, load, and other characteristics; to calculate statistics for various processes; to benchmark the performance and scalability of the system; and to predict and take necessary steps in case of business and data growth.

In general, Latitude provides different types of performance testing - stress testing, performance testing, load testing, soak testing, scalability testing, stability (reliability) testing and volume testing - to evaluate a solution's productivity and ensure that it meets all requirements.

Application Security Testing

We validate the reliability of your software's user and system security, protecting end users from the theft or loss of private and sensitive data, as well as guarding against other intrusions, including:

  • Unauthorized access, accidental or deliberate, to programs and system data by users with unauthorized or limited access
  • Theft of critical data, including user logins, passwords and payment information
  • Application Security Best-Practices Analysis
  • Dynamic testing of web applications against major types of attacks: XSS, SQL Injection, buffer overflows, manipulations of the address bar and source code revealing
  • Intrusion tests (access control, authentication, input validation, cryptography reliability, error handling)
  • Testing of payment mechanisms in different web systems
  • Vulnerability testing of system's third-party components
  • Security code audit (use of static code analysis tools, manual review of major components of the system, recommendations on improvements, patches, security alerts)
  • Server configuration testing (search for errors in multithreaded environments that allow data to be shared or corrupted)

Full Lifecycle Testing

Full life-cycle testing is a sequence of different phases, each having a specific input and output. In full lifecycle testing, development and testing stages are coordinated to complement each other. These stages are described below.

  • QA Strategy Development And Planning
  • Software Requirements Testing
  • Full Functional Specification Testing
  • Full System Design Analysis
  • Test Cases and Plan Creation
  • Prototype Testing
  • Standard QA Testing
