Ramanagowda Hullur - PeerSpot reviewer
Staff Engineer at Stryker
Automation has transformed mobile testing workflows and delivers reliable end-to-end coverage
One painful point that still exists with Appium, especially in iOS mobile application testing, is its reliance on WebDriverAgent, which creates a lot of stress during setup for beginners. Although many improvements have been made since MCP, that area still needs attention. Additionally, improvements in the locator strategies are needed to adapt to modern technologies for locating mobile applications developed outside traditional Apple or core scripting technologies like Swift, Java, or Kotlin. A community needs to emerge, driven by a set of industry leaders who can help people and contribute to the community, especially since platforms like Stack Overflow have diminished in relevance due to the rise of AI. If I could change or improve one thing about Appium, I would focus on enhancing Appium MCP to ensure it delivers what it promises reliably.

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

"It's one of the most stable solutions for mobile automation."
"Appium helps me to do as much as much as I want to."
"The library is extensive so the driver interacts with most functions or actions on mobile devices."
"It has great documentation and excellent community support."
"Previously, we wrote all the end-to-end mobile application functionality automation manually, but with Appium MCP, our productivity has increased tenfold as it can generate scripts, debug, and auto-heal itself, reducing the time spent in scripting and debugging test cases."
"We do not need to pay for the solution. It’s free."
"Many reference areas on the web can help you understand the product quite well."
"We get a list that shows all devices that are connected to the system."
"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

"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."
"It breaks down."
"The product was a bit difficult to install. It wasn’t easy. We had issues."
"Installation of this particular tool is tedious, and it gives you a good number of challenges at times."
"The deployment process and configuration are quite complex and require improvement."
"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."
"It should provide reliable and promising executions every time without any interruptions and avoiding any synchronization issues."
"I'm facing a lot of issues with my new juniors when they set up Appium for iOS."
"One area where k6 could improve is by introducing a GUI similar to JMeter."
 

Pricing and Cost Advice

"There is no license for this solution because it is open-source."
"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."
"It's completely 100% free, and there are no hidden fees."
"The solution is open source so it is free."
"Appium is free and open-source."
"Appian is open-source, which is not licensed."
"The solution is open source."
"Appium is open source; we can use it for free."
