Speechify is absolutely brilliant. Growing up with dyslexia this would have made a big difference. I’m so glad to have it today.

K6 reviews

"Developer-Friendly Performance Testing Tool & Infrastructure" What do you like best about k6? -Excellent documentation and supportive blogs (and video content like the Office Hours series) content simplifies getting started with k6 -Developer-friendly -- Easy to install and get going in the CLI. Makes performance testing more accessible to not just a few, but all of those on an engineering team. This is so important as performance testing is no longer just an expectation of a single niche quality team because of limitations of licensing or knowledge of an antiquated tool. -k6 cloud -- So far, ensuring the ability to scale our tests beyond the resource of our machines has been reassuring. The analyses and comparison features between test executions is helpful so far. Looking forward to the continued work against this infrastructure platform. Review collected by and hosted on G2.com. What do you dislike about k6? -The user experience of using k6 with npm modules is not consistent with what you expect from typical development -xk6 extensions conceptually are great as a community is helping to build out a need. Just be cautious of utilization as they may not be supported long-term, though these extensions are featured in k6 documentation. Review collected by and hosted on G2.com. What problems is k6 solving and how is that benefiting you? k6 has made performance testing an accessible practice for engineering teams. It's a rather low barrier to entry (getting started with k6) , yet you can get as advanced as you with, customizing your scripts as you need to get the insights required. Because of this tool, I'm seeing engineering teams starting to take on the responsibility of knowing and testing the limitations of their APIs and tiers.

"K6-Game changer for API Load and Performance test" What do you like best about k6? It is developer friendly and easy to write load tests and has excellent documentation. Most importantly it is a straightforward K6 report that can tell where the performance issues are. We did a thorough analysis where we compared several tools/frameworks and we can tell with full confidence that K6 is much superior compared to other tools. These are some of the benefits: It is easy to install and start writing the first L&P test, code review It is great community support and excellent documentation Excellent Report and Integrates with NewRelic, CloudWatch if we decide to retire later it is easy to do because we can still run locally without being locked to one tool. I would call the K6 a modern L&P framework that can beneficial for any company. Review collected by and hosted on G2.com. What do you dislike about k6? I wish it had better support for HTTP protocols. It is awesome with API test but not so great with UI load test. Review collected by and hosted on G2.com. What problems is k6 solving and how is that benefiting you? Ensuring that API we develop performance well at Production. It is not a guessing game anymore. It is a data-driven decision.

What do you like best about k6? It's ease of use, readability and its fantastic set of constantly evolving features, paired with a vibrant community - which together with its good performance makes, to me, the best option for performance testing. And its extensibility as well... Tests are code, as they should. And readable code! Review collected by and hosted on G2.com. What do you dislike about k6? There is an extensibility /plug-in system but some integrations are still not covered… To complain about something, its only issue is that apart from the excellent readability of the tests, they still need to be written, so you need to know what you are doing- thank god- I still have a job. But give it time… (summary: tests needs to be written, haha) And the fact that you have to write in JavaScript - it would be fantastic to write in your own language such as C# as in my case :) Review collected by and hosted on G2.com. Recommendations to others considering k6: Check other options, make your own decisions. My criteria might not match yours. My decision points were the performance vs. features, mainly its code readability, how easy it is to define a real test, its open model, and extensibility. Review collected by and hosted on G2.com. What problems is k6 solving and how is that benefiting you? excellent, readable performance tests that evolve with the application, as code. One test source code fits all, so its simplicity is key.

TestComplete reviews

Ease of managing test script especially for regression testing.

- Tamoya B.

"Great when it works" What do you like best about TestComplete? TestComplete is a pretty robust automated testing tool. I've been using it for about 9 years. It does take some time to learn and unlike the salespeople push it to be plug and play or record and playback, there are some scripting skills needed to get your test scripts working consistently for regression testing. It's been a 9 year learning curve but I've gotten there. Review collected by and hosted on G2.com. What do you dislike about TestComplete? Their license utility leaves little to be desired. The department in charge of licensing should take off the tin foil beanies and be a little less paranoid over their product. Believe me, it's not something worth pirating. Most anti-virus software blocks this license product and getting them to get along has been a nightmare. Review collected by and hosted on G2.com. Recommendations to others considering TestComplete: Make sure your users are technical savvy. During my first training with TestComplete 9 years ago, it was very obvious that the sales team had sold the product as record and playback and that anyone can use it. The other participants in the training class were apparent business users and were not technically minded and were completely lost in the scripting instructions. Review collected by and hosted on G2.com. What problems is TestComplete solving and how is that benefiting you? It's really beneficial for regression testing. However, the scripts have to be watched and adjusted for network fluctuations and delays added to accommodate.

"It has been very useful for us to perform performance tests as well as performance and interface" What do you like best about TestComplete? It has a fairly complete, powerful and intuitive interface so you don't need to be a programming expert to be able to use it without any problem, the fact that it allows me to perform different tests on my programs and developments is something of great help When I want to verify the proper functioning of my entire program in a much safer, more accurate, faster and more reliable way, the quality of the reports generated after performing the software analysis is quite complete and objective, which helps me make decisions. in a much faster way regarding how we are going to solve the problems detected in the best possible way without generating long delays in the final delivery of the software. Review collected by and hosted on G2.com. What do you dislike about TestComplete? It has some errors that can affect the performance of this application during its use, especially slowing it down or even leaving the program frozen, which happens very frequently, the solution? As there is no other option than to restart the entire application and start the tests from scratch. Review collected by and hosted on G2.com. What problems is TestComplete solving and how is that benefiting you? It has been very useful for us to carry out different tests both of operation and performance and interface for users in a fairly fast and simple way, so that we can be able to identify and correct existing errors in our applications in one much simpler and faster way instead of carrying out manual tests of our systems by members of our work team.
