Types of Testing Performed
Zillexit performs exhaustive testing encompassing various testing types and test levels:
Unit Testing
Unit testing verifies the smallest testable units of code like classes, functions, interfaces, etc. in isolation. Zillexit leverages unit test automation frameworks like JUnit, NUnit to accelerate unit testing.
Our unit tests are written by developers to test individual units of source code as they are developed. We use stubs and mock objects to simulate dependencies and inputs. Unit tests are run continuously as part of our build process to catch issues early. We ensure each code unit has a corresponding set of unit tests to maximize coverage.
Unit testing promotes modular code design and helps detect logical errors and bugs quickly during development. We rigorously unit test critical business logic and functions that get reused across the system. This ensures any changes do not break existing functionality.
Integration Testing
Integration testing validates interactions between integrated components and interfaces. Zillexit performs extensive automated API testing during integration.
When individual software modules are integrated, integration testing verifies the interfaces and combined functionality works as expected. Our integration testing ensures components developed by different engineers work together correctly.
We simulate end-to-end transactions that span multiple systems and validate the end-to-end flow. Automated API tests are used to validate backend services integration without the user interface. Integration testing provides confidence in the system architecture early.
System Testing
System testing evaluates end-to-end system workflows and requirements under production-like environments. Realistic test data is used for thorough system testing.
We test the fully integrated system to verify it meets business and technical requirements. System testing is black-box testing performed from an end-user perspective. We configure production-like test environments and databases to simulate real-world usage scenarios and data. Our test cases validate all key system functions, failure cases, and integration touchpoints.
System testing provides insights into system-level defects, inconsistencies, performance issues, and data errors. It builds confidence that the finished system will work as expected before release. We involve business analysts, QA and UX teams in collaborative system testing.
Regression Testing
Regression testing re-runs test cases to check no new bugs or issues have emerged after changes to the code. Test automation helps accelerate regression testing at Zillexit.
Regression testing is done after enhancements or bug fixes to ensure existing functionality still works correctly. Our automated regression test suite runs on every code change to detect any unintended side effects. We continuously expand regression test coverage based on defects found previously.
Regression testing provides confidence that product quality is maintained over iterative development. We optimize regression testing to run frequently without slowing down development velocity. Test automation and effective test case prioritization are key enablers of rapid regression testing.
Performance Testing
Performance testing measures the system’s responsiveness and stability under heavy user loads. Zillexit undertakes load, stress, spike, and endurance testing to benchmark performance.
We simulate high user traffic and peak loads on the system to uncover performance bottlenecks. Load testing verifies behavior under maximum expected usage while stress testing overloads the system to test its robustness.
Our performance tests measure response times, resource utilization, and throughput metrics under different workloads. Performance testing ensures the system can scale smoothly and identifies capacity planning requirements before launch. We tune the system configuration and architecture based on performance test findings.
Security Testing
Security testing finds vulnerabilities in the system that can be exploited by hackers. Zillexit performs penetration testing, audit of authentication, encryption, etc. to identify security gaps.
We conduct comprehensive security tests to detect weaknesses that can compromise sensitive data or enable cyber attacks. Penetration testing mimics real-world attacks to exploit vulnerabilities that hackers can potentially use.
Our security assessment examines authentication mechanisms, access controls, encryption, data security, server configuration, network security, etc. Security testing is integrated into multiple stages of our development lifecycle. We remediate all high and medium risk security defects before software release.
Compatibility Testing
Compatibility testing verifies software compatibility and consistent behavior across different operating systems, browsers, devices and third-party integrations.
We test our software across diverse environments and third-party systems it must interact with. Compatibility testing validates UI rendering, workflows, integrations, data exchange, etc. work as expected on target platforms.
Our test matrix includes latest OS versions, major browser versions, iOS and Android variants, and simulated legacy environments. We confirm compatibility issues are gracefully handled. This provides assurance of seamless omnichannel user experience.
Accessibility Testing
Accessibility testing validates compliance with accessibility standards and usability of the system for people with disabilities.
We assess compliance with applicable accessibility regulations and conventions. Our accessibility testing methodology checks color contrast, screen reader support, keyboard navigation, and other assistive requirements.
Testing focuses on identifying barriers that can inhibit usage for disabled users. User groups representing different disabilities take part in hands-on accessibility testing. We take prompt measures to eliminate uncovered accessibility defects.
Localization Testing
Localization testing evaluates Zillexit’s software adaptations across different languages, regional preferences, and cultural nuances.
We validate localized UI, content, formats, integrations, and documentation meet target market needs. Our localization testing verifies translated text, locale-specific data formatting, imagery, colors, icons, and conventions.

Incomplete Requirements
Inadequate and frequently changing requirements make test case design difficult and lead to rework. Unclear requirements result in testing gaps that allow defects to pass through.
For example, a vague requirement like “easy login” leaves room for interpretation. More specifics are needed to test properly. Requirements should clearly define expected behavior.
Manual Testing Overheads
Manual testing is time-consuming, repetitive, and lacks thoroughness beyond a point. But automating every test scenario is challenging too. Finding the optimal balance is key.
Testing complex workflows with many conditional steps often requires manual validation. But purely manual testing slows the feedback loop and cannot scale.
Release Time Pressures
Insufficient time allocated for proper testing in release schedules impacts quality. Shortcuts taken to meet deadlines result in uncaught defects.
Difficulty getting timely access to test environments due to shared resources further squeezes testing. Careful test planning is needed to prevent last minute quality issues.
Test Environment Setup
Replicating the complexity of real-world production environments for testing can be difficult for some applications. Lack of test data and environments that mirror production can lead to false test successes.
For example, testing a big data analytics app requires setting up large datasets to test at production scale.Simplified test environments miss some defects.
Inter-team Coordination
Seamless collaboration between dev, testing and ops teams is vital for test automation, CI/CD, monitoring and other needs. Lack of alignment causes delays.
Teams should agree on tools, environments, test data needs etc. early. Testers should be involved in requirement reviews to plan test scenarios better.
Analyzing Test Results
Analyzing large test outputs, logs and telemetry data to identify root causes of failures is challenging. Isolating the source among complex dependencies requires domain knowledge.
Test management tools that aggregate results and intelligent diagnostics using ML/AI can help. Teams also need to review logs and repro failures collaboratively.
