Functional testing

Functional testing services for web and SaaS products

Functional testing answers: does this feature work for real users? TestSync Lab delivers remote functional testing services — requirements-based checks plus exploratory judgment — inside monthly retainers for US and global product teams.

Why SaaS teams hire TestSync Lab

  • Requirements + exploration

    We verify acceptance criteria and still hunt the edge cases scripts miss.

  • Engineer-ready defects

    Severity, steps, environment, evidence in Slack or Jira.

  • Pairs with API and automation

    Functional UI work sits beside /api-testing-services and /automation-testing-services as you grow.

Problems this retainer replaces

  • Ticket-only testing with no product sense

    We understand business logic — permissions, billing, workflows.

  • Functional testing only at the end

    Retainers keep functional coverage on every weekly release.

  • No link to regression

    New functional finds feed the regression pack on /regression-testing-services.
