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

What QA and test automation services does MarsDevs offer?

MarsDevs builds automated test suites, performance testing frameworks, security assessments, and CI/CD quality gates for engineering teams who need to ship with confidence. We have delivered 50+ QA programmes with a 10x average regression cycle reduction and a strong quality track record across regulated-industry clients.

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

MarsDevs has built production QA programmes for product 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 audit-ready test programmes for regulated FinTech and HealthTech clients, 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.

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.

QA Engagement Process

How We Build QA That Actually Catches Bugs

Scope

Test scope definition, risk assessment, and coverage strategy. We define what needs to be tested, what the risk profile is, and which types of testing will deliver the most value for your product.

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.

Frequently Asked Questions

Questions, meet answers.

It depends on where you are starting from. If you have no automation, we start with a test scope and risk assessment in week one, build the first suite covering your highest-risk flows in weeks two and three, integrate it into your CI/CD pipeline so it runs on every commit, and hand over a maintained, living suite that grows with your codebase. If you already have some automation but it is flaky or incomplete, we audit what exists, fix what is salvageable, eliminate what is not, and extend coverage systematically. Every engagement starts with a free scoping call before any commitment.

A focused automation suite covering your highest-risk flows is typically production-ready in three to four weeks. A comprehensive suite covering full regression, API contract tests, and CI/CD integration takes six to eight weeks for a medium-sized product. We deliver working automation in the first two weeks rather than spending the first month planning. You see tests running in your pipeline before the engagement is halfway through.

QA is the discipline of ensuring a product meets its quality requirements across its full lifecycle — including requirements review, test design, defect management, and release sign-off. Test automation is a subset of QA: writing code that executes test cases automatically so humans do not have to run them manually. Both matter. Automation without QA thinking produces suites that test the wrong things. QA without automation produces teams that cannot release fast enough to compete. We do both.

Unit tests verify that individual functions behave correctly in isolation. They do not verify that those functions work correctly together, that the full user journey completes without failure, or that your API behaves correctly when a third-party dependency sends an unexpected response. Most production bugs live in the gaps between units: integration points, state machine edge cases, concurrent user scenarios, and environment-specific behaviour. Integration tests, end-to-end tests, and contract tests cover these gaps. Unit tests alone never will.

A flaky test is one that passes on some runs and fails on others for reasons unrelated to the code being tested — typically because it depends on timing, shared test data, network availability, or undetermined state from a previous test. Flaky tests are dangerous because they train engineers to ignore test failures. Once a team starts clicking re-run on a failing test instead of investigating, the test suite has lost its value as a quality gate. We include flaky test triage in every engagement and replace chronically flaky tests with deterministic equivalents.

We run a baseline profiling exercise first to understand how the system behaves under current load, then identify the specific bottlenecks — typically N+1 query patterns, missing database indexes, connection pool misconfiguration, or synchronous processing where async is needed. We then load test at 3x, 10x, and peak expected load using realistic user journey simulations rather than simple endpoint hammers. After remediation, we retest against the same scenarios and document the before and after benchmarks. The output is performance evidence your team and your enterprise clients can rely on.

Yes. We build QA programmes for regulated industries with audit-ready evidence artefacts. Regulatory technical audits require more than test coverage — they require documented evidence artefacts structured to the specific standard being audited, demonstrating that specific control requirements are being continuously verified. We design the test programme with the audit requirements in mind from the start, so the evidence exists before the auditor asks for it rather than being assembled retrospectively under deadline pressure.
