Systematic testing coverage from functional verification to performance and security.
Manual Functional Testing
Test cases mapped to every requirement in your SRS. 100% requirement traceability, systematic execution, defect logging with reproduction steps and retest verification after fixes.
Test Automation
Selenium for web UI, Appium for mobile apps, RestAssured for APIs, TestNG/JUnit as test runners. Automated suites in CI/CD pipelines give pass/fail results within minutes of a code commit.
Performance and Load Testing
JMeter and Locust simulations to find your application's maximum concurrent user capacity, response times at different load levels, and the specific bottlenecks limiting performance.
Security Testing
OWASP Top 10 coverage: SQL injection, XSS, broken authentication, insecure direct object references and security misconfiguration. Structured penetration testing with detailed remediation guidance.
Regression Testing
Ensure new releases do not break previously working functionality. Automated regression suites run on every build, catching regressions within minutes of a code change before they reach users.
UAT Support
Business-language UAT test scripts, facilitated UAT sessions, defect tracking and prioritisation, and sign-off documentation to authorise go-live with confidence.
Why Choose SSIS India for QA and Testing
100+ Device Test Lab
Physical devices covering all popular Android and iOS phones and tablets, OS versions ranging from 10 years old to latest, plus Windows and Mac machines with all major browsers.
Industry Domain Expertise
Our QA engineers do not just test features - they bring domain knowledge (banking, healthcare, logistics, e-commerce) to provide inputs based on real-world usage scenarios your developers may miss.
QA Process Consultation
We help you implement QA processes and strategy, select the right tools, and produce documentation that can help you achieve process certifications and product quality certificates.
Requirement Traceability
Every test case is mapped to a requirement in your SRS. This guarantees 100% coverage of agreed functionality and provides audit evidence that every feature was verified before go-live.
Integrated with Your Dev Team
We work within your existing development process - Agile, sprint-based or waterfall. QA runs in parallel with development so testing does not become a bottleneck before release.
Low-Cost, High-Quality
Competitive rates for professional QA services. The cost of proper testing is always lower than the cost of production bugs - lost orders, regulatory risk, customer complaints and emergency fixes.
Why Software Quality Assurance Matters for Your Business
Every bug that reaches a production environment costs significantly more to fix than a bug caught during testing. This is not just a technical observation - it has direct business consequences. A bug in your online payment flow means lost orders. A bug in your hospital billing software means revenue leakage or compliance issues. A bug in your logistics app means wrong deliveries and angry customers. A bug in your banking application means regulatory risk.
Quality assurance is not a cost - it is insurance against far larger costs. SSIS India's QA and testing services provide that insurance systematically, using structured testing methodologies rather than ad-hoc manual checking.
Types of Testing We Perform
Functional Testing: Verifying that every feature works as specified in the requirements. We create test cases from requirements documents (ensuring 100% requirement traceability), execute them systematically, log defects with detailed reproduction steps and retest after fixes.
Integration Testing: Modern software systems integrate with many external services - payment gateways, SMS providers, government APIs, third-party ERPs, logistics platforms. Integration testing verifies that data flows correctly between your application and these external systems, that error responses are handled gracefully, and that the integrated system behaves correctly under real-world conditions including network delays and service timeouts.
Performance and Load Testing: How does your application behave under high load? An application that works perfectly with 10 concurrent users may crash with 500. Performance testing identifies the maximum load your application can handle, the response times users experience at different load levels, and the specific bottlenecks that need optimisation. We use JMeter and Locust to simulate realistic load patterns.
Security Testing: Web application security testing covers the OWASP Top 10 vulnerabilities - SQL injection, cross-site scripting (XSS), broken authentication, insecure direct object references, security misconfiguration and more. For applications handling financial data, patient data or personal information, security testing is not optional. We conduct structured penetration tests and provide detailed remediation guidance.
Regression Testing: Every time new functionality is added to software, there is a risk that something that was working before has broken. Regression testing ensures that new releases do not introduce bugs in previously working functionality. For applications with frequent releases, we develop automated regression test suites that run on every build - catching regressions within minutes of a code change.
User Acceptance Testing (UAT) Support: We support your business users through UAT by preparing UAT test scripts written in business language (not technical test cases), facilitating UAT sessions, tracking and prioritising UAT defects, and preparing the sign-off documentation needed to authorise go-live.
Test Automation for Faster Releases
Manual testing is time-consuming and expensive. For applications with frequent release cycles, automated testing significantly reduces the time from code completion to confident release. We build automated test frameworks using Selenium (for web UI testing), Appium (for mobile app testing), RestAssured (for API testing) and TestNG or JUnit as test runners. Automated tests run in CI/CD pipelines and provide pass/fail results within minutes of a code commit, enabling same-day releases with confidence.
