Regression Testing Across Every Layer

From UI to database and everything in between, our regression suites validate the full application stack so that nothing slips through on release day.

🖥️

Functional Regression

End-to-end validation that every user journey and business workflow continues to behave correctly after each code change or sprint delivery.

User StoriesAcceptance CriteriaEdge Cases
🔌

API Regression

Contract and behaviour validation for every REST, GraphQL, and SOAP endpoint to ensure backward compatibility across services and consumers.

Contract TestingSchema ValidationResponse Assertions

UI Visual Regression

Pixel-level comparison of every screen state to detect unintended layout shifts, colour changes, and rendering anomalies introduced by CSS or component updates.

Pixel DiffingCross-BrowserResponsive

Database Regression

Data integrity and schema-migration validation ensuring that every release preserves existing records, constraints, stored procedures, and reporting accuracy.

Mobile Regression

Automated regression across real Android and iOS devices and emulators, covering every OS version and screen size critical to your user base.

Performance Regression

Baseline benchmarking and continuous performance comparison to detect response-time degradations and throughput drops introduced by new code changes.

Our Regression Testing Services

A complete range of regression testing engagements — from one-off manual test execution to a fully owned, CI/CD-integrated automation platform tailored to your release cadence.

01

Manual Regression Testing

Structured exploratory and scripted regression executed by certified QA engineers who understand your product domain and catch defects automation misses.

  • Risk-based test case prioritisation
  • Domain-expert exploratory sessions
  • Detailed defect reporting with repro steps
  • Sprint-aligned execution scheduling
  • Sign-off reports for every release
02

Automated Regression Suite

A bespoke automation framework built on Selenium, Playwright, or Cypress that owns your full regression scope and runs on every commit.

  • Framework architecture & build from scratch
  • Page Object Model / Screenplay pattern
  • Parallel execution for speed
  • Self-healing locator strategies
  • Full knowledge transfer & documentation
03

Visual Regression Testing

Percy or Applitools integration that automatically catches unintended UI changes across browsers, viewports, and themes with zero human effort.

  • Baseline snapshot management
  • Cross-browser visual diffing
  • Responsive breakpoint coverage
  • Dark mode & theme regression
04

API Regression Testing

Continuous contract and functional validation of your APIs using RestAssured, Postman Newman, or Karate DSL integrated into your build pipeline.

  • OpenAPI / Swagger spec validation
  • Consumer-driven contract tests
  • Negative & boundary scenario coverage
  • Automated pipeline execution
  • Diff alerts on schema changes
05

Database & Data Regression

Automated pre- and post-deployment data validation ensuring every release leaves your persistent data layer intact and accurate.

  • Schema migration regression checks
  • Row-count & aggregation assertions
  • Stored procedure & trigger validation
  • ETL pipeline data quality checks
06

CI/CD Regression Pipeline

End-to-end pipeline design that runs the right subset of regression tests at each stage — unit, integration, and E2E — with fail-fast gates and full reporting.

  • Stage-gated execution strategy
  • Jenkins / GitHub Actions / GitLab setup
  • Slack & email failure notifications
  • Allure / ExtentReports dashboards
  • Historical trend & flakiness tracking

Our Regression Testing Process

A repeatable, five-phase methodology that transforms your regression testing from an ad-hoc activity into a structured engineering discipline.

01

Regression Scope Analysis

We review your application architecture, release history, and defect logs to identify the highest-risk areas and define a prioritised regression scope aligned to your sprint velocity and business impact.

Risk AssessmentDefect History ReviewScope Document
02

Test Suite Design

Our QA architects design a lean, high-coverage test suite using techniques such as boundary-value analysis, equivalence partitioning, and decision-table testing to maximise defect detection with minimum test count.

BDD ScenariosTest Case DesignData Strategy
03

Automation Framework Build

We engineer a production-grade automation framework with self-healing locators, modular architecture, and data-driven parameterisation — built to scale with your product for years, not just the current sprint.

CI/CD Integration

The full suite is wired into your pipeline with stage-gated execution — smoke on every commit, full regression on release candidates — with real-time Slack notifications and rich HTML reporting dashboards.

Maintenance & Optimisation

We provide ongoing suite maintenance — updating tests for new features, fixing flaky cases, and continuously optimising execution time — so your regression suite remains an asset, not a liability.

What Sets Our Regression Practice Apart

We don't just run test cases — we engineer a regression safety net that gives your entire engineering team the confidence to ship fast without breaking things.

⬅️

Shift-Left Regression Strategy

Regression thinking starts at story-writing time. We embed acceptance criteria directly into automation, catching defects before they ever reach QA.

🤝

Framework Ownership Transfer

Every framework we build is fully documented and handed over to your team with pair-programming sessions, so you're never dependent on us to maintain it.

🔧

Self-Healing Test Scripts

Using AI-assisted locator strategies, our scripts automatically adapt to minor UI changes, dramatically reducing the maintenance burden after each release.

🚫

Zero Flaky Test Policy

We enforce a strict zero-flakiness policy. Any test that fails intermittently is quarantined, root-caused, and fixed before the next sprint cycle completes.

🏃

Sprint-Velocity Aligned

Our regression execution schedule is synchronised with your sprint cadence — no bottlenecks at release time, no last-minute surprises for your development team.

📋

Full Defect Traceability

Every regression failure is linked to a JIRA ticket, a root-cause category, and a fix-verification test — giving management complete visibility into quality trends.

Tools & Frameworks We Use

We select and configure the right toolchain for your specific technology stack, team skill set, and release pipeline — no vendor lock-in, no forced migrations.
