JH Jitka H. Mid-Market (51-1000 emp.) 4/4/2023 "Excellent testing partner with global reach and strong collaboration" 5/5 What do you like best about Testlio? We’ve had a very positive experience working with Testlio as an external software testing partner. They have been a reliable extension of our internal teams and consistently deliver high-quality testing support across a range of projects. One of the standout strengths of Testlio is their global network of testers. This enables true real-world testing across multiple regions, devices and environments, something that is very difficult to replicate with internal teams alone. They are particularly valuable when testing needs to cover different geographies, device types, user scenarios at scale. Collaboration has been excellent throughout. Testlio integrates well into existing project structures, communication is clear, responsive, well organised. Having a dedicated communication channel and a structured approach to sharing documentation and updates makes day-to-day collaboration straightforward and efficient. They are also highly responsive and adaptable. Whether refining test scope, answering detailed questions or adjusting to project timelines, the team engages proactively and works closely with stakeholders to ensure alignment. This is particularly important in projects where requirements evolve. From a delivery perspective, Testlio provides structured testing execution, comprehensive defect reporting, regular progress updates. This helps maintain visibility and control throughout the testing lifecycle. Their outputs are clear and actionable, making it easy for internal teams to prioritise and address issues quickly. Another key benefit is their ability to support specialist testing needs, including areas such as accessibility and broader quality assurance coverage that may not always be fully resourced internally. Overall, I'd highly recommend Testlio to organisations looking for a scalable, professional, collaborative testing partner. They are especially valuable for teams that need global coverage, diverse device testing, additional capacity without compromising on quality. Review collected by and hosted on G2.com.

What problems is Testlio solving and how is that benefiting you? Testlio provides a QA team if your QA team is absent or busy. User acceptance testers may be busy with their day to day work and not able to provide thorough enough testing. Testlio extends the team. The Testlio testers are experts in testing, they have an eye for detail that users may not have. Writing test scripts could be time consuming, especially for someone who doesn't do it every day. Testlio resolved that problem by producing their own test scripts based on limited information we provided. These test scripts were also useful for our own internal testers. Testing world-wide provides an excellent opportunity to check in-situ if the site works as it should in that country, without using proxy servers, which may be unreliable.
