Abhishek-Tiwari - PeerSpot reviewer
Has cross-platform flexibility and a record-and-play option
The challenging part with Appium is that installation can be a bit tricky. It can be challenging to set up in Android versus iOS environments. Appium has some limitations in terms of writing code using simulators and online cloud devices. I faced challenges with native based scenarios, battery turn out percentage, battery charging percentage, and memory capacity. The other challenge I faced involved codes changing from device to device. For example, the piece of code that works in iOS version 10.1 won't work in iOS version 6.0. In upcoming releases, if they can reduce some more of the dependencies like SDK, UIAutomator, etc., it would be great. That is, I'd like to see a consolidated package or bundle release that is much more user-friendly.
NalinGoonawardana - PeerSpot reviewer
Offers good scalability and has the ability to integrate with various systems and services
One area where k6 could improve is by introducing a GUI similar to JMeter. While k6 is a powerful tool for performance testing, it leans heavily towards coding. Having a GUI, even if it is a low-code approach, could make it more accessible to a broader audience. It would be beneficial to strike a balance where basic tasks can be performed graphically through a user-friendly interface, while still allowing the flexibility for more complex operations through code, similar to how JMeter operates. This could enhance the user experience and make k6 more approachable for those who may not be as comfortable with scripting.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Appium helps me to do as much as much as I want to."
"It can be used with different programming languages."
"What I like about Appium right now is that it's like Cypress in the sense that............. to test the components in the way I want them to be tested."
"Appium's best feature is that it supports multiple frameworks."
"We develop apps using the React Native framework, and Appium integrates well for testing those apps. The Appium automation framework also has good integration with GitHub Actions and plenty of other tools and frameworks, including BrowserStack."
"It runs completely flawlessly and seamlessly every day."
"The most valuable feature of Appium is it supports iOS and AOS and is open-source."
"The latest versions of the solution are stable."
"The tool's big advantage is that it is more performance-test oriented for experienced testers who know what they are doing. In a normal working setup, performance engineers frequently work with DevOps and development teams. For these teams, k6 Open Source's syntax is much simpler and easier to understand and apply in the working process."
"The standout feature of k6 is its strong focus on API performance testing."
 

Cons

"One thing which can be really helpful is that there is some kind of a recorder made available rather than scripting everything."
"The initial setup is straightforward if you have previous experience with the solution, but it can be complicated for a novice user."
"I rarely use Appium nowadays because I'm now at the managerial level, but the last time I used it, whenever I selected and clicked on an element, Appium was very slow. I tried to debug it, but I still couldn't find the problem, so this is an area for improvement in the solution. Another area for improvement lies with the connector and server. For example, the effort to get into the local machine sometimes causes the emulator to become slow, which then leads to failure in testing, and this is the usual issue I've encountered from Appium. An additional feature I'd like added to Appium in its next release is being able to do automation in iOS without using XPath and the name of the element. In Xcode, you can use previous UI tests for detecting elements, but in Appium, you have to use Xpath and the element name instead of being able to directly put the X-UiPath, which is what you can do in Xcode. In iOS as well, sometimes the element doesn't have a name or a path. Sometimes, there's also no element."
"They should add an in-built framework."
"There is always a concern about the amount of code that is required to enhance the automation process. The idea of having less code or no code is what we would like to see in future updates."
"The setup and installation were a problem for us at first."
"An application developed on the Unity platform, such as a gaming application, objects are moving in that case. Interacting with those elements is still lacking in Appium. Appium doesn't have the internal library to play with the Unity platform. That is a huge lack right now."
"The challenging part with Appium is that installation can be a bit tricky. It can be challenging to set up in Android versus iOS environments."
"One area where k6 could improve is by introducing a GUI similar to JMeter."
 

Pricing and Cost Advice

"This is an open source solution so it does not cost anything for licensing or otherwise."
"The solution is free."
"As far as I know, Appium is a free solution. It's not for commercial use."
"We found out that we could explore features of the solution for 30 days trial. We can switch to a permanent license later if we want."
"Appian is open-source, which is not licensed."
"It's completely 100% free, and there are no hidden fees."
"The solution is open source."
"There is no license for this solution because it is open-source."
