What is Quality Assurance?

Quality Assurance at Startup House is not an end-of-cycle check. We embed testing into your development process from the first sprint. Our QA engineers work alongside your developers, writing test cases in parallel with code and running automated pipelines on every build.

We cover functional testing, performance testing, security testing, regression testing, and end-to-end flows. Manual testing handles edge cases and complex user journeys. Automated testing handles regression suites and repetitive checks. Both run together.

The result: releases your team ships with confidence, not releases you hold your breath for.

Let's talk

How we make quality part of how you build.

01

QA Audit and Test Strategy

We review your current product, codebase, and testing coverage. We define what needs manual coverage, what needs automation, and how QA integrates into your sprint cycle.

02

Test Case Design

We write test cases for all functional flows, edge cases, and user journeys. We document acceptance criteria and map test coverage to your product requirements.

03

Manual and Automated Testing

We execute manual testing on complex flows and perform end-to-end validation of new features. We build and maintain automated test suites for regression and performance coverage.

04

Performance and Security Testing

We test your product under load to verify it handles real-world traffic. We run security scans to identify vulnerabilities before release.

05

Release Sign-off and Ongoing QA

We validate every release before it goes live. We maintain your test suite as your product evolves and integrate QA into your CI/CD pipeline for continuous coverage.

From Manual to Automated

We don't start from scratch. We take your existing manual test cases and convert them into automated tests, step by step.

From Manual to Automated

We don't start from scratch. We take your existing manual test cases and convert them into automated tests, step by step.

Gradual conversion.

We take validated manual test cases and automate them using Cypress or Playwright.

CI/CD integration.

Automated tests run on every code change, giving your team fast, reliable feedback without manual triggers.

AI-assisted test writing.

We use AI tooling to accelerate test creation and scale the automation practice efficiently.

What you gain when QA runs with development.

Fewer production incidents.

Catching bugs before release costs a fraction of fixing them in production. Your support queue stays manageable and your engineers focus on building, not firefighting.

Faster release cycles.

Automated regression suites run on every build without waiting for manual checks. Your team ships more frequently without adding testing overhead.

Launch with confidence.

Every release goes through a documented sign-off process. Your team knows what was tested, what passed, and what risk level you are shipping with.

QA integrated, not added on.

Our QA engineers work inside your sprint cycle alongside your developers. Testing is not a gate at the end. It is part of how the work gets done.

Outpace competitors with stability.

Frequent bugs damage user trust faster than slow development does. A stable, reliable product keeps users engaged and reduces the churn your competitors are ready to capture.

From reactive bug fixing to a stable release process.

A bug found in development costs your team an hour. The same bug found in production costs days of engineering time, a support backlog, and user trust you cannot fully recover. The math on QA investment is straightforward.

Frequently asked questions

What types of testing do you offer?

We cover functional testing, regression testing, performance and load testing, security testing, usability testing, cross-browser testing, and end-to-end testing. The mix we recommend depends on your product type, release cadence, and risk areas.

Do you offer automated testing, manual testing, or both?

Both. Automated testing handles regression suites and repetitive checks efficiently. Manual testing covers complex user journeys, exploratory testing, and edge cases that scripts cannot anticipate. We define the right balance for your product during the audit phase.

How do you integrate QA into an existing development team?

We embed our QA engineers into your sprint cycle. We attend sprint planning, write test cases in parallel with development, and run testing on every build. You do not need to change your process significantly. We adapt to how your team works.

How long does it take to set up a QA process from scratch?

For a product already in development, the timeline depends on scale, but initial setup typically takes 2 to 3 weeks: QA audit, test strategy, and first test case library. Automated pipeline setup runs alongside the first testing cycle.

Can you take over QA for a product already in production?

Yes. We start with an audit of your current test coverage, identify the highest-risk areas, and build from there. We do not require a clean slate.

How do you handle testing across web and mobile platforms?

We test across browsers, operating systems, and device types. For mobile, we test on both iOS and Android, covering native apps and responsive web. Cross-platform test coverage is documented in the test strategy from the start.

What does a QA audit include?

We review your existing test coverage, identify untested critical paths, assess your automation maturity, and map risks by severity. You receive a report with prioritized recommendations and a proposed test strategy.

Ready to ship without the last-minute panic?

Start with a QA audit. We identify your highest-risk areas and show you exactly where your coverage falls short.
