❓ Frequently Asked Questions (FAQ)
What types of software testing services are typically offered?
Most software testing companies in the UK provide a mix of functional testing, automated testing, regression testing, performance/load testing, usability testing, and security testing. Some also specialize in domain-specific QA (e.g., healthcare, fintech, eCommerce).
Can UK companies work with offshore or nearshore QA teams effectively?
Absolutely. Many UK-based companies work seamlessly with offshore partners like Enozom Software, using Agile frameworks, shared tools (e.g., Jira, TestRail), and overlapping time zones. Success depends on clear communication, solid onboarding, and defined SLAs.
What’s the typical cost of hiring a QA company in the UK?
Pricing varies. UK-based QA services typically range from £40–£90/hour, while offshore partners charge between £15–£40/hour. Fixed-price contracts are also common for well-scoped projects. Be sure to confirm rates for manual vs. automated testing.
How do QA companies ensure quality and consistency?
Reputable QA firms follow industry standards like ISTQB, ISO 9001, or CMMI. They use test case management tools, bug tracking systems, and automation frameworks to ensure repeatable, traceable QA processes. Many also provide detailed test documentation and audit logs.
Do testing companies supply their own tools?
Yes—many testing vendors provide their own licenses for tools like Selenium, Appium, JMeter, or proprietary platforms. Some also integrate with your existing tools (e.g., GitHub, Jenkins, Azure DevOps). Be sure to clarify this during onboarding.
What’s the difference between managed testing services and staff augmentation?
Managed services mean the QA provider handles the entire testing process end-to-end, including planning, execution, and reporting. Staff augmentation adds QA engineers to your team under your process and control. Choose based on your internal QA maturity.
How do I evaluate the effectiveness of a QA provider?
Look at case studies, client testimonials, and industry awards. Ask about past projects in your sector, success metrics (e.g., defect reduction rate, time-to-market improvements), and how they handle regression or critical issue scenarios. Trial projects or proof-of-concepts can also help gauge their capabilities.
What should be included in a QA service agreement or contract?
A QA service agreement should cover scope of testing, types of services (manual/automated/security/etc.), service level agreements (SLAs), reporting cadence, tools used, communication protocols, IP and confidentiality terms, and pricing models. Ensure clear exit criteria and ownership of test artifacts.
Are QA companies responsible for security testing too?
Yes—many QA firms offer specialized security testing, such as penetration testing, vulnerability assessments, and data privacy validation. Ensure your QA vendor has certified security testers (e.g., CEH, CISSP) and a proven process for identifying and mitigating risks.
Can QA firms work with Agile and DevOps pipelines?
Absolutely. Top-tier QA companies are well-versed in Agile, Scrum, and DevOps methodologies. They can integrate into CI/CD pipelines using tools like Jenkins, GitLab CI, or Azure DevOps to enable continuous testing and faster feedback loops.
How often should testing cycles be run?
Testing frequency depends on your development model. Agile teams may require testing after each sprint (bi-weekly), while traditional models might test before major releases. Continuous delivery environments benefit from daily automated regression and smoke tests.
Is it better to outsource all QA or keep some in-house?
A hybrid model often works best—retain strategic QA roles in-house for deep domain knowledge, and outsource tactical or high-volume testing (like regression or load testing) to external experts. This balances cost, control, and scalability.
