Software Testing & Quality Assurance

Software Testing & Quality Assurance Services

Software Testing and Quality Assurance are essential to software development services. A balanced approach to manual and automated testing efforts is carefully applied to reduce the risk of faulty or malfunctioning software, ensure predictability and reliability, and meet each client's needs and requirements.

Quality assurance and testing services are an integral part of every software project, big or small, across a range of technology domains. Testing and quality control can be achieved manually, using test automation, or a mix of the two. 

Symphony Solutions sets up QA/QC processes, whether part of full-cycle software development, QA consulting, or a full-service QA outsourcing project. 

Software testing and QA services include functional and non-functional testing, as well as test advisory services. Functional testing requires a healthy balance of manual and automation testing, while non-functional testing will focus on the verification and validation of software performance, reliability, scalability, usability, accessibility, and security. Clients may also request test advisory services provided by Symphony Solutions’ QA experts. 

As a team of Agile practitioners, Symphony Solutions uses QA functional testing services, including unit tests, integration tests, API tests, contract tests, and end-to-end UI testing of the product.

Our QA and Software Testing Services

Functional Testing
Manual Testing

Manual testing is the cornerstone of a high-quality control process. Knowledge of different business domain specifics and product logic helps the QA and testing services team to apply relevant test techniques and tools to analyze software behavior and output. Our quality assurance and test engineers are trained in web and mobile technologies, databases, networking, security, software installation, and configuration.

Test Automation

The purpose of test automation is to make frequent routine quality control checks more quickly, so, tests should be repeated during development cycles. Every time the source code is modified, relevant tests should be repeated. For each release or deployment of the software, it may be tested on all supported operating systems and hardware configurations. Manually repeating these tests is costly and time-consuming. Once created, automated tests can be run over and over again at no additional cost, and they are much faster than manual tests. There is one downside of automation, that it doesn’t detect new defects. But even so, automated software testing can reduce the time it takes to run repetitive tests from days to hours or even minutes. A time saving that translates directly into cost savings.
Symphony Solutions achieves this by applying the relevant automation tools, either COTS or building custom testing frameworks, which are then used for creating and maintaining individual test scripts and scenarios within specific business domains. These automation tests are included as part of deployment and delivery pipelines, especially for projects with short release cycles. Symphony Solutions also have solid experience in performance, load, and stress testing of web applications.

Functional Testing
Performance Testing

Performance Testing is essential to securing a strong foundation of your software product and guaranteeing that it runs like clockwork. Understanding how your system behaves under different workloads, helps identify its weak points, address the issues, and make your software solution stable, reliable, and consistent.

Security Testing

Security Testing helps identify any vulnerabilities in your IT solution and address the issues early on in the software development life cycle. This helps avoid running into the risk of data breaches and system breakdowns, detect malicious activities and intrusion attempts, protecting your organization from potential cyber-attacks. Organizations are getting affected every day by security allied incidents such as network intrusion, Cross Site Scripting and DDoS attacks. Our security testers are certified ethical hackers. Our approach is in conformance with international standards including OWASP and OSSTMM.

Usability Testing

Usability Testing evaluates your application from the perspective of a user and helps understand if it’s easy to use and provides a satisfactory user experience. Our software testing team will emulate how the user interacts with the application, and detect any issues, such as a confusing interface or difficult navigation, or other bugs that deter one from using the app as intended.

Software Testing Consulting

Symphony Solutions’ QA professionals can offer you their expertise in the form of Software Testing consulting services to help your organization establish a reliable Quality Assurance system and guide your teams through improving their software testing practices. Our software testing consulting includes three stages:

Stage 1: Discover Phase
Stage 2: Analyze Phase
Stage 3: Recommend Phase

We cover the following key activities in these 3 stages:

  • Understand the current business strategy and how it translates to QA/testing specific goals and objectives.
  • Access current testing processes and practices and identify opportunities for improvement.
  • Review the usage and utilization of tools in testing and their integration with other tools in SDLC.
  • Understand the development, configuration management and release management processes.
  • Develop a roadmap of improvements to help align QA strategy with the organizational goals.

Software Testing Process

The Symphony Solutions QA and testing team has experience in small, mid-size and massive projects (with QA teams of over 50 engineers). For our clients, this experience is used to define and design testing strategies on a range of sizes, scales, and detail involved, including data quality assurance for big data projects.

Software testing services start with an analysis of project requirements and a clear definition of KPIs. Using this analysis, the scope and depth of the testing required are defined by the QA and testing team. Quality KPIs might be just a few essential metrics or extensive and sophisticated analytics based on root-cause analysis of defects, impact analysis for proposed code changes, and risk assessment across a range of features.

Quality assurance provides guidelines across the whole company, for every phase of the Software Development Life Cycle (SDLC) within Software Testing Life Cycle (STLC).

STLC is a sequence of specific activities conducted during the testing process to ensure software quality goals are met. STLC involves both verification and validation activities. Contrary to popular belief, Software Testing is not just a single/isolate activity, i.e., testing. It consists of a series of activities carried out methodologically to help certify your software product. STLC stands for Software Testing Life Cycle.

Quality gates are implemented through processes and procedures like (definition of functional requirements, user-readiness, peer reviews, formal demos, user acceptance testing, and sign-off process). Engineers use tooling such as code quality analysis tools, unit and integration tests, and continuous integration.

Software testing services FAQs

What is functional testing?

Functional testing is the part of software testing aimed at validating that the product meets customer’s functional requirements and is able to execute expected functions. Basic functionality gets tested against a set of predetermined specifications.

Non-functional testing is a type of software testing that checks properties of the product that don’t determine its functionality but are essential to a positive user experience, such as performance, usability, reliability, security, etc.

There are different types of application security testing, which can be categorized by access to the source code (black-box, white-box, and grey-box testing); techniques (vulnerability scanning, security scanning, penetration testing, security audit, ethical hacking, risk assessment, posture assessment); tools (static, dynamic, or interactive, mobile application security testing, software composition analysis).
