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.

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."
"Appium's best feature is that it supports multiple frameworks."
"Appium has easy interaction with mobile."
"The library is extensive so the driver interacts with most functions or actions on mobile devices."
"We get a list that shows all devices that are connected to the system."
"The most valuable feature of Appium is it supports iOS and AOS and is open-source."
"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 can be used with different programming languages."
"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

"We previously worked with native applications, and there weren't any good mobile app testing tools. We started working with React Native, which works well with Appium, but it would be good to see better integration; the way elements are displayed can be messy. React Native is very popular nowadays, so it's essential to have that compatibility."
"The deployment process and configuration are quite complex and require improvement."
"We haven't been able to fully leverage Appium for multiple reasons. I think number one is just that the tests take a long time to run. We have had some issues around just the results themselves and how predictable they are, but those are not issues with Appium directly."
"It needs to accommodate applications that use React.js and AngularJS."
"Support-wise, it could be better."
"Configuration-wise, there is a lot of room for improvement."
"The user interface needs improvement because there are issues when setting up environment variables."
"They should add an in-built framework."
"One area where k6 could improve is by introducing a GUI similar to JMeter."
 

Pricing and Cost Advice

"The solution is open-source."
"Appium is free and open-source."
"The price is good for people to be able to make a favorable decision for the value."
"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."
"The solution is open source so it is free."
"The solution is open source."
"This is an open source solution so it does not cost anything for licensing or otherwise."
"Appian is open-source, which is not licensed."
