AS
Independent consultant, at OpenText
Efficient mobile testing with intuitive emulation capabilities and a user-friendly interface
Initial setup for Appium (especially for iOS) is not beginner-friendly.Consumes too much of your host machine's resources, potentially slowing down the machine.Appium Inspector often lacks deep insight or crashes with certain app builds. Improve test flakiness by intelligently selecting robust self-healing locators,simplified installers, better documentation, GUI-based config management,smart wait mechanisms and better failure logs.

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

"This solution has improved our organization in terms of efficiency."
"Appium has easy interaction with mobile."
"The way Appium server interacts with mobile apps is fantastic. It provides all the information about the elements inside the app, Android as well as iOS. I can interact with the element quickly, just type some text or get some text values from the element - whether it's a drop-down, or web text, or a native element."
"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."
"This is the best test automation tool for any mobile test automation engineer."
"We get a list that shows all devices that are connected to the system."
"Appium is a great tool, and I recommend it."
"The solution helps with test automation. We focus mostly on Java."
"The standout feature of k6 is its strong focus on API performance testing."
"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."
 

Cons

"Another room for improvement in Appium is that it's buggy sometimes."
"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."
"Appium has problems with automated validations following iOS updates, causing us to have to validate manually. Its execution speed is also very slow."
"Support-wise, it could be better. Whenever we get some issues, it may take some time."
"What needs improvement in Appium is its documentation. It needs to give more context on the libraries that Appium is using under the hood. For example, my team is using Appium for Android automation, and a lot of times, I feel that there's functionality that's available through the Appium interface, that exists within the UIAutomator, but there aren't a lot of useful or helpful resources on the internet to find that information, so it would be good to have some linkage with the underlying platform itself. Another room for improvement in Appium is that it's buggy sometimes. For example, at times, there's a bug in the inspector application that doesn't allow me to save my desired capability set, so it would be nice to get that bug fixed, but overall, Appium is a good tool. The Touch Actions functionality in Appium also needs improvement. For example, if I want to initiate a scroll on the device that I'm running Appium on, sometimes Swipe works, but in other situations, I have to explicitly use action chains, so I'm not too sure what's the better approach. What I'd like to see in the next version of Appium is a more intelligent and more intuitive AppiumLibrary, in terms of identifying menus and scroll bars, etc., because right now, I'm unsure if I have to do a lot of export reversals to get to the elements I'm looking for. It would be nice to have some functionality built in, which would allow me to easily get those exports."
"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."
"The setup and installation were a problem for us at first."
"It should provide reliable and promising executions every time without any interruptions and avoiding any synchronization issues."
"One area where k6 could improve is by introducing a GUI similar to JMeter."
 

Pricing and Cost Advice

"It's completely 100% free, and there are no hidden fees."
"The solution is open-source."
"This is an open source solution so it does not cost anything for licensing or otherwise."
"I'm unsure if there's any cost associated with Appium. I got the free package which includes the server GUI application and the inspector application, and it was free to download, and that's all I need to get my work done. I'm not aware of any additional costs associated with the tool."
"There is no license for this solution because it is open-source."
"It's open source, so it's completely free."
"The solution is open source."
"As far as I know, Appium is a free solution. It's not for commercial use."
