What does MarsDevs offer in terms of Quality Assurance and Test Automation?

MarsDevs provides comprehensive quality assurance services including manual and automated testing, integration testing, performance testing, regression testing, and continuous testing through CI/CD integration.

How does MarsDevs implement Test Automation in the development cycle?

We incorporate test automation throughout the development lifecycle. Automation is embedded into the CI/CD pipelines, ensuring that tests are executed frequently and efficiently. This helps in faster release cycles and consistent product quality.

What tools and frameworks do you use for Test Automation?

MarsDevs uses a range of industry-standard tools for test automation such as Selenium, Cypress, JUnit, and Appium for mobile applications. We tailor the choice of tools to the specific needs and complexity of the project.

How do you ensure test coverage and reliability in automated tests?

Our approach includes writing clean, maintainable test scripts and ensuring they cover critical workflows. We implement continuous integration and run automated tests across multiple environments, ensuring broad test coverage and reliability.

Can you handle performance and security testing as part of QA?

Yes, in addition to functional testing, we offer performance testing using tools like JMeter and LoadRunner. We also conduct security testing to identify vulnerabilities, ensuring the application is secure and scalable.

How do you manage manual testing alongside automated testing?

While we emphasize automation for repetitive tasks, we also perform manual testing for exploratory, usability, and edge cases. This combination ensures that the application is both functional and user-friendly.

How do you report test results and issues?

We provide detailed test reports that highlight pass/fail rates, error logs, and bug tracking. These reports are integrated with your project management tools like Jira, ensuring transparent communication and quick resolutions.

Quality Assurance & Test Automation Services

We find the bugs before your users do, not after.

MarsDevs has built production QA programmes for founders and engineering teams across FinTech, HealthTech, E-commerce, and B2B SaaS since 2019. We build automated test suites that block bad code, performance frameworks that catch bottlenecks before scale, and security assessments that close vulnerabilities before regulators find them.

Most teams test in production without realising it. Manual regression cycles take days, miss the same defects repeatedly, and slow every release. Automated QA is not a cost it is the difference between shipping with confidence and shipping with fear.

Our QA engineers have built test programmes that have passed FCA, MAS, and HIPAA technical audits, identified critical vulnerabilities before go-live, and reduced regression cycles from days to minutes. We work directly with your engineering team without adding coordination overhead.

What we test

Test Automation Engineering

Playwright, Cypress, Selenium, and Appium suites that run on every commit and block broken code automatically. We build automation that your team trusts, not flaky suites that get ignored.

Performance and Load Testing

Baseline profiling, bottleneck identification, and load testing at 10x to 100x production scale. We find the breaking point before your users do, and produce the evidence your enterprise deals require.

Security and Penetration Testing

Application penetration testing, OWASP Top 10 coverage, API security assessment, and dependency auditing. We find vulnerabilities before regulators and attackers do.

API and Contract Testing

OpenAPI specification coverage, Pact contract testing for consumer integrations, and automated API regression that catches breaking changes before they reach any downstream system.

Mobile App Testing

Automated testing across real iOS and Android devices covering the device and OS fragmentation your users actually run. We use cloud device farms, not emulators.

CI/CD Quality Gate Integration

Test pipelines integrated into your deployment workflow with quality gates that block merges and deploys on failure. Deploy with confidence instead of crossed fingers.

Quality gates block merges and deploys on test failure
Per-PR isolated test environments eliminate shared environment noise
Deploy confidence measured by hotfix rate, not team opinion

Regression Testing

Full regression in under 30 minutes on every push
Characterisation testing for legacy systems with no existing tests
Parallel-run validation for migrations and major refactors

User Acceptance Testing

Structured UAT programmes for enterprise rollouts: test script design, business user training, defect management workflows, and go-live readiness criteria that make the launch decision evidence-based.

Structured test scripts mapped to business processes
Defect management workflow connecting UAT to development queues
Go-live readiness framework with documented sign-off criteria

Manual and Exploratory Testing

Expert-led exploratory testing that finds the defects automation misses: edge cases, UX inconsistencies, and business logic gaps that require human judgement and domain knowledge to surface.

Session-based exploratory testing with structured reporting
Domain-specific testers matched to your industry context
Defect density analysis to identify the highest-risk areas

E-commerce Checkout Regression

Zero checkout failures across 14 payment methods after automated regression coverage.

Overview

A high-growth Indian e-commerce platform was releasing code every two weeks and consistently breaking checkout flows across one or more of its 14 supported payment methods. Manual regression took 4 days to complete, delaying every release and still missing defects that reached production. A broken Paytm integration had caused a 9-hour checkout outage during a sale event, costing an estimated 2.3 crore in lost GMV. MarsDevs built a full automated regression suite covering all 14 payment methods, checkout state machines, cart edge cases, and coupon application logic. The suite ran on every pull request and nightly, reducing regression cycle time from 4 days to 22 minutes. The platform has had zero payment-related production incidents in the 11 months since the suite went live.

Challenges

14 payment method integrations each requiring regression on every release, taking 4 days of manual testing.
A broken payment integration during a sale event caused a 9-hour checkout outage and 2.3 crore in lost GMV.
No automated coverage of cart edge cases or coupon logic, which were the highest defect source after payments.
Engineers were self-certifying releases without structured regression, creating hidden risk on every deploy.

Solutions

Built a Playwright-based regression suite covering all 14 payment method integrations with simulated success and failure states.
Cart edge case library covered 140 scenarios including concurrent adds, coupon stacking, and inventory depletion mid-checkout.
Suite integrated into CI/CD pipeline, running on every pull request and blocking merge on regression failure.
Nightly full regression with Slack alerts gave the engineering team complete visibility before the business day started.

Plan

Test plan design, framework and tooling selection, and test environment setup. Architecture decisions made before a single test is written so the suite scales without refactoring.

Build

Test case development, automation script engineering, and CI/CD pipeline integration. Every test written to a standard that survives a codebase that keeps changing.

Execute

Test runs across real devices, environments, and data sets. Defects logged with reproduction steps and severity ratings. Nothing marked as passed until it actually passes.

Report

Coverage metrics, defect density analysis, and risk-rated findings with remediation cost estimates. Evidence artefacts structured for regulatory audit where required.

Maintain

Test suite maintenance as your codebase evolves, flaky test triage, and continuous expansion of coverage as new features ship. A QA programme that grows with the product.
