Quality assurance and software testing

Quality assurance is the discipline of knowing what your software does before your users find out. That means automated coverage where it pays off, deliberate manual testing where it does not, and a release process that treats quality as a gate rather than a hope.

We work as part of your delivery cycle rather than as a downstream department that receives finished work and reports problems too late to be cheap.

What you get

Test strategy
What to automate, what to test by hand, and what genuinely does not need testing. Coverage without a strategy is just expense.
Automated test suites
Unit, integration and end-to-end coverage that runs in your pipeline and fails loudly enough to stop a bad release.
Manual and exploratory testing
Structured human testing for the failures automation does not catch — confusing flows, broken states, and the paths nobody specified.
Regression testing
A dependable safety net so that shipping a change does not mean re-verifying the whole product by hand.
Accessibility and compatibility
Testing against WCAG criteria, real browsers and real devices, rather than the one configuration the team happens to develop on.

Technologies we work in

What comes up most often — not a boundary. Teams are assembled per engagement, so we staff for the stack your project actually uses.

End-to-end

  • Playwright
  • Cypress
  • Selenium

Unit and integration

  • Jest
  • Vitest
  • pytest
  • JUnit

API and load

  • Postman
  • k6
  • JMeter

Mobile

  • Appium
  • XCTest
  • Espresso

How we work

  1. Assess current quality

    Where defects come from, what is covered, and what keeps reaching production.

  2. Agree the strategy

    A written plan for what gets tested and how, sized to your release cadence and risk.

  3. Build the suites

    Automation written to be maintained — flaky tests get fixed or deleted, never left to erode trust in the suite.

  4. Integrate into CI

    Tests run on every change, with results your team will actually read.

  5. Test each release

    Ongoing manual and exploratory passes alongside the automation, focused where the risk is.

Senior engineers, in your time zone

There is no junior bench here, so there is nobody to rotate onto your work to keep a seat warm. And because the team works from Argentina, you get a full working-day overlap with North America — questions get answered the same day, not the next one.

Common questions

Can you add tests to a project with none?

Yes, and it is a common starting point. We begin with the paths where a failure would hurt most rather than chasing a coverage percentage, so the suite is useful long before it is complete.

Do you replace our developers' testing?

No. Developers should keep testing their own work; a QA function exists to catch what that misses and to own the strategy. The two are complementary, and treating QA as a substitute produces worse software.

Who actually works on my project?

Senior engineers, every time. WizardsLabs has no junior bench to keep busy, so there is no one to rotate onto your work to fill a seat. Each engagement is staffed with hand-picked engineers matched to what you are building.

How does the time-zone overlap work?

The team works from Argentina, which sits within one to three hours of US Eastern for most of the year and keeps a full working-day overlap with every North American time zone. Stand-ups, pairing and same-day answers all happen in normal business hours for both sides — not at the edges of the day.

How do you handle flaky tests?

We treat them as defects in the suite. A test that fails at random trains a team to ignore red builds, which is worse than not having the test at all.
