EngineeringQA & Testing

Quality starts before the first line of code.

We test your software from the first requirements to the next release, catching issues before they become harder to fix.

QA engineers and developers work together, combining hands-on testing, automation and AI-assisted work to check new features and protect what already works.

Build quality into every stage.

  • PREVENT

    Find issues before code.

    Review requirements and designs for gaps, ambiguity and inconsistent behavior before implementation.

  • VERIFY

    Check what users rely on.

    Test core journeys, individual components and the connections between services.

  • PROTECT

    Keep changes from breaking things.

    Check every new build and repeat regression tests as features and fixes are added.

Our approach

From requirements to release decisions.

  1. 01

    Review & plan

    Bring QA into requirements and design reviews. Agree on expected behavior, critical journeys and the scope of testing.

  2. 02

    Test each build

    Run smoke tests to check build stability, then test features, components and integrations against requirements.

  3. 03

    Automate & repeat

    Automate suitable repetitive checks. Verify fixes and run regression tests to catch unintended effects on existing functionality.

  4. 04

    Report & refine

    Share test results, reproducible defects and remaining risks. Use findings to guide fixes and improve coverage for the next release.

Maintained tests for suitable recurring scenarios, alongside hands-on QA.
Visibility into release quality.
Test results, unresolved issues and coverage gaps to support the decision to release.
Why Cleevio

QA starts early. Quality is shared.

Our QA engineers join the process during requirements and design. Developers contribute unit tests and peer code reviews throughout implementation.

We combine manual testing with automation where it makes recurring checks more efficient. AI tools support the work, with engineers responsible for reviewing the output.

QA and development work together to investigate failures, verify fixes and improve the next release.

QA: scenarios, testing and defect verification

Developers: unit tests and peer review
