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.

Performance Test Engineer at BETBY
Lighter on the RAM and has native Grafana support
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. Recently, I had a case where I was using another tool, and there wasn't enough memory for it because it required more RAM. k6 Open Source, on the other hand, is lighter and doesn't have a UI, which is beneficial. An engineer I was training could use k6 Open Source scripts even without my help. The tool is more efficient and has native support with Grafana, as both are developed by the same company. This integration enhances monitoring and loss ratio tracking. Thanks to its intelligent GUI, k6 Open Source's design is simpler, particularly for complex scenarios. When we need to manage hundreds of thousands or millions of transactions per minute, the solution becomes a game-changer compared to JMeter.

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."
"The automation part is extremely helpful in streamlining our processes."
"The most valuable feature of Appium is it supports iOS and AOS and is open-source."
"We do not need to pay for the solution. It’s free."
"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."
"Within a single command, we can easily connect to the device."
"I like that Appium is an opensource tool, I also like its cross-platform flexibility, and Appium provides a record-and-play option with commands that are the same as those that Selenium uses so a person who has some exposure to Selenium will be able to write a piece of code in Appium."
"The solution helps with test automation. We focus mostly on Java."
"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

"If it had more facility for configuration it would be a spectacular solution."
"Installation of this particular tool is tedious, and it gives you a good number of challenges at times."
"Image recognition could be improved. We have some images in our mobile applications. It should be able to run from the cloud, so we can automate the catcher."
"Stability is an area that needs some improvement."
"There is always a concern about the amount of code that is required to enhance the automation process."
"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."
"One area where I think Appium could improve is in addressing security concerns for our data. Currently, we're unable to use cloud solutions like CloudForm due to security restrictions on our servers. We also face challenges in updating packages for the same reason. It would be beneficial if the solution could provide better support for auto-reporting and easier connections to mobile device farms."
"Configuring the project to be used in Appium is a little bit tedious."
"One area where k6 could improve is by introducing a GUI similar to JMeter."
 

Pricing and Cost Advice

"The price is good for people to be able to make a favorable decision for the value."
"The solution is open source so it is free."
"Appian is open-source, which is not licensed."
"The solution is free."
"As far as I know, Appium is a free solution. It's not for commercial use."
"There is no license for this solution because it is 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."
"Appium is open source; we can use it for free."
