Quality Assurance Services

Many organizations around the world face downtime in their applications because of glitches in their software. This leads to severe issues related to system availability which directly impacts the bottom line of the company. This will also put an organization's reputation at stake in front of the stakeholders and the customers.

Tetrasoft's Software Quality Assurance practice is oriented towards "prevention" of errors in each and every phase of the software development lifecycle. Our innovative, expertise and quality driven defect detection methodology ensures early detection of defects to avoid defect multiplication throughout the process. It ensures that all agreed-upon standards, processes and procedures are adhered to and resulting in other benefits like the following:

  • Fewer latent defects in software, resulting in reduced effort and time
  • Higher system availability
  • Higher reliability
  • Reduced maintenance costs
  • Reduced life cycle costs of software

Tetrasoft's Quality Assurance service offerings include the following:

In real time environment the manual testing becomes very essential, as 100 percent automation is not possible. Manual testing plays a vital role in Business critical applications where functionalities change quite often.

Tetrasoft's manual testing service involves the oldest and the most reliable form of testing, which aims to uncover as-yet-undiscovered errors and record software bugs or discrepancies related to the functionality of the application.

The steps involved in manual testing are as follows:

  • Understand the functionality of the application
  • Prepare and Setup a test environment
  • Analyze and acquire/prepare Test data
  • Execute test case(s) manually
  • Verify the actual result
  • Record the result as Pass or Fail
  • Make a summary report of the Pass and Fail test cases
  • Publish the report
  • Record any new defects uncovered during the test case execution

Tetrasoft, out of its vast experience has noticed that many organizations who have invested in automation testing tool do not get a good Return On their Investment (ROI) as they have not chosen the right tool or right test cases to automate.

The most important aspect of Automation Testing is the selection of the right tool. Tetrasoft’s automation testing service helps customers invest in the right test automation tool by doing a “Pros and Cons” analysis of the various tools available in the market

Our proficiency includes Automation Testing for products and applications across multiple domains.

Security Testing, in simple terms, is a process to determine that an information system protects data and maintains the functionality that was originally intended.

At Tetrasoft, we have a team of Security testing experts, who are experienced in solving the critical security challenges faced by our clients. We follow a risk-based approach, which is grounded in system’s architectural reality to gauge the software security adequately. We perform a deep analysis of the application in order to minimize the possibility of exploitation by any kind of malicious attacks. We aim at finding vulnerabilities that can affect the applications. We accomplish this by managing security assessment tools and techniques.

Our security testing practice revolves around the following six basic security concepts:

  • Confidentiality
  • Integrity
  • Authentication
  • Availability
  • Authorization
  • Non-Repudiation

To remain competitive in today’s world, it becomes very essential for every organization to predict the performance capability of their software applications. Organizations must make sure that their applications are optimized to deliver the experience their users demand like applications being fast, relevant, easy to use, aesthetically pleasing, and satisfying.

Tetrasoft has rich and varied experience in performance Testing. Our team of Performance Testing engineers use their years of experience to analyze and decrease application performance bottlenecks that block intended business functionality and performance. They determine how fast some aspects of a system perform under a particular workload to evaluate the reliability, scalability and interoperability of the application.

Our Performance Testing services include the following:

  • Application Performance Monitoring
  • Load Testing
  • Stress Testing
  • Volume Testing
  • Soak and Reliability Testing
  • Performance Benchmarking
  • Performance Diagnostics Testing
  • Scalability Testing and Capacity Planning
  • Performance Code Reviews/Profiling
  • System Characterization

Migrations can be risky and if not engineered properly will fail to give expected results. For a migration to be successful it is necessary to perform Quality Assurance and testing before the application is into production. Migration Testing is most expensive in terms of money and time. It demands resources with the appropriate experience, specialization skills, and tools.

Whether it is Application Migration, Database Migration, Platform Migration or Technology Migration, Tetrasoft has a complete understanding of the problems that arise from migration. Our migration testing practice covers all the above scenarios to help our customers achieve:

  • Cost Savings
  • Enhanced performance and scalability, post migration
  • Minimize risks

Tetrasoft's System Integration Testing (SIT) service ensures that different modules/systems interact with each other well and render the same levels of performance. It also ensures that there is proper exchange of data between dependent systems.

A ‘Black Box’ approach to SIT is what Tetrasoft follows and recommends to its customers. The endeavor of Tetrasoft’s SIT approach is to cover as many paths as possible through the applications based on different data and actions of the users.

Tetrasoft’s SIT Test design techniques for developing test cases are as follows:

  • Equivalence Partitioning
  • Boundary Value Analysis
  • Decision Table Testing
  • State Transition Testing
  • Use Case Testing
  • Usability Testing

Tetrasoft follows a phase wise approach for its Test Process Consulting service. As part of this service, we provide well defined software testing norms, standards and procedures, templates and documents, testing metrics and measurements and test acceptance criteria.

Our comprehensive consulting service also provides the following benefits to the customer:

  • Reduced downtime; high availability
  • Reduction in the number of errors
  • Adherence to industry standards and procedures
  • Lower maintenance overheads
  • Reduction in the cost of testing
  • Overall improvement in the test process maturity
