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

"The solution provides one roof or framework for both iOS and Android code bases."
"I haven't explored other solutions in this particular area, but what I like best about Appium is the fact that it shares functions with Selenium. The extension of Selenium functions allows me to use all of the methods that exist in that domain, and it just makes it simpler for me. I've been using Selenium for some time as well, so using Appium just seems like a natural fit for me."
"Appium is a great tool, and I recommend it."
"It has great documentation and excellent community support."
"It runs completely flawlessly and seamlessly every day."
"For our company, Appium's similarity with Selenium is important as we use Selenium."
"Many reference areas on the web can help you understand the product quite well."
"The solution is easy to use."
"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

"Configuration-wise, there is a lot of room for improvement."
"Sometimes, the Appium server won't connect with the mobile application because of some socket issues, so network connectivity between applications and the Appium server could be improved."
"Installation of this particular tool is tedious, and it gives you a good number of challenges at times."
"When doing mobile testing Appium is difficult as you can't use it for mobile testing in virtual machines."
"Appium can improve when the case fails, there should be a feature where you can generate the report from Appium. Once you're on a test case, automatically the screenshot should be captured which would avoid manual intervention. These features would be beneficial to migrate to Appium."
"It should provide reliable and promising executions every time without any interruptions and avoiding any synchronization issues."
"Appium is not that scalable, if you're using real devices locally."
"One thing which can be really helpful is that there is some kind of a recorder made available rather than scripting everything."
"One area where k6 could improve is by introducing a GUI similar to JMeter."
 

Pricing and Cost Advice

"The solution is open-source."
"The price is good for people to be able to make a favorable decision for the value."
"The solution is free."
"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."
"The solution is open source."
"It's open source, so it's completely free."
"Appium is free and open-source."
"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."
