FAQ

QA
questions

Common questions before you start.

Talk to Us β†’
Do you write tests or just run them?+
Both. We write automated test suites from scratch, add tests to existing projects, and run manual exploratory QA. For new projects we advocate test-writing alongside development rather than as a separate phase.
What coverage percentage do you target?+
80%+ line coverage for unit tests on business logic, 100% coverage of critical paths (auth, payments, data mutations) with integration tests. We don't chase 100% overall coverage β€” we focus coverage on risk.

Our Process

How we deliver

A clear, milestone-based process with no surprises.

01
Test Strategy
Week 1

Define what to test, at which layer, with what tools. Risk-based prioritisation.

02
Environment Setup
Week 1

CI integration, test database seeding, environment parity, and API mock setup.

03
Unit & Integration Tests
Week 2–4

Tests written alongside code. We work in your dev workflow, not after it.

04
E2E Automation
Week 3–6

Playwright tests for critical user journeys β€” sign-up, checkout, core flows β€” run on every PR.

05
Load Testing
Week 5–6

k6 or Locust to validate performance SLAs. Identify bottlenecks before production.

06
Security Testing
Week 6

OWASP Top 10 manual checks, dependency scanning, SQL injection, XSS test suite, DAST.

🎯
Risk-Based

We prioritise by business risk, not coverage metrics. Critical paths get bulletproof coverage.

πŸ“Š
Measurable

Coverage reports, execution trends, and defect density metrics visible every sprint.

Client Reviews

What clients say about our work

"

Nexcode wrote our entire Playwright E2E suite in 3 weeks. It runs on every PR, catches regressions in 4 minutes, and has prevented 6 production incidents. Deploy frequency went from weekly to daily.

"k6 load test revealed a database N+1 query that would have taken down the API at 500 concurrent users. Found in staging, fixed in 2 hours. Paid for itself before we went live."

"Security testing found 4 OWASP issues in our fintech platform. Fixed them all, passed pen test first time, got SOC2 certification 6 weeks later."
