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.

Rapid delivery has transformed complex enterprise apps and supports faster cross-domain projects
Every platform or low-code platform tool is quite good in its own area, but there is always space to groom or enhance or improve. The same is with OutSystems as well. A couple of things from the integration point of view can be enhanced. If your application or the enterprise organization is tackling a huge data application where you have bulk amounts of data, it becomes a challenge for all the technologies and the same with OutSystems. You have to design your architecture in a very magnificent and decent way so that how you process your data so that load can be easily balanced. Data handling and huge data handling is a kind of challenge you may need to face. Then we have some vendor lock-in. If you are trying to migrate your application from OutSystems, then you probably get into this vendor lock-in system. Some organization may face challenges if some organization is on a small scale size. The small scale businesses may find OutSystems costly because of its high cost and pricing due to the licensing cost. Apart from that, OutSystems really plays well, and it needs a learning curve. If a traditional application or programming is there which your developers are skilled into and they are directly deployed into OutSystems, it may take some significant amount of time for them to get comfortable with OutSystems. There is a learning curve. OutSystems community is already in place, but it can more be enhanced regarding some aspects. They did organize lots of bootcamps and other user groups as well, but those can also be improved from the documentation point of view and having some integration guidebook as well. A couple of things which can be improved into OutSystems include the licensing cost, the vendor lock-in side, the learning curve, couple of integration aspects and customizations.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Our clients have realized benefits by reducing their testing cycle from three days to three hours through Appium."
"For the particular use case we used Appium for, we felt that it served our purpose completely, and we haven't had any issues with the Python Client for Appium."
"It can be used with different programming languages."
"The latest versions of the solution are stable."
"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."
"We chose Appium for the scalability and the ease of automation for both Android and iOS."
"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."
"For our company, Appium's similarity with Selenium is important as we use Selenium."
"One of the valuable features of OutSystems is the very small lead time for the delivery of projects."
"The OutSystems' most effective features for speeding up development cycles are the process orchestration and the drag-and-drop updating of business processes."
"Fast for server-side development."
"Our previous solution had other overheads such as release management, version management, code management, monitoring, etc., all of which are built-in with OutSystems."
"We've used features like batch processing timers, components, and integrations with other systems like SAP, which have accelerated our development process.In terms of productivity, we've seen a 30 percent reduction in screen design time and an additional 10 percent improvement when implementing client requirements. OutSystems' integration capabilities have significantly enhanced our app's functionality, making it quicker and easier to connect with other systems."
"It is very stable."
"We used almost all of the features, themes, styling guide, and approach components. They are useful in our applications."
"It is a stable solution, and the initial setup is straightforward."
 

Cons

"The installation part of Appium is somewhat clumsy, requiring numerous dependencies and configurations."
"The product was a bit difficult to install. It wasn’t easy. We had issues."
"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."
"We need some bug fixes for nested elements."
"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."
"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."
"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 needs to accommodate applications that use React.js and AngularJS."
"I like the OutSystems platform. I am working on integrating it with another platform using APIs, however, it has proven to be difficult. The main issue I am facing is obtaining authorization tokens as well as access and refresh tokens. It may be due to my lack of knowledge of APIs as it is new to me."
"The asynchronous processing and multithreading tasks for which the current resources of the platform are very generic and not built for the end-user. Any asynchronous jobs have to be constructed with an end-user dashboard to allow inspection of the status of the activities."
"The resource availability needs to be increased."
"The technical support is not very good but I still give it a six out of 10."
"We had some lagging issues under high data loads, and the solution needed to be customized to improve this."
"The technical support is quite good, although it could be better: it currently fluctuates a little depending on how busy they are."
"I have difficulty in using several new features. Some of the product's features are tricky to use as well."
"The integration points need to be increased. People have also started to adopt this solution for their regular needs. That means it's not only the big enterprises that are adopting this solution. There are also small and medium enterprises that are adopting it. I've read that where you have large deployments, OutSystems starts to crumble a bit. That is the idea that no customer would know at the beginning and would also not like to hit the wall there. When it is on the client, there are a lot of applications already on low-code, and then suddenly you realize that you want to do some big applications, and you face hurdles. This is the general feedback for all such platforms."

"You should contact OutSystems for more details but my opinion is that it is not for small business budgets."
"The subscription is billed on a yearly basis."
"It is not an expensive product, especially if you have access to more features and deal with more projects."
"It is still very expensive, so small companies can’t generally afford it... Still, the time saving on development and delivery is worth the value."
"OutSystems is expensive, and they changed the pricing model in the last couple of years. It's changing too much and it's becoming unstable. They are constantly shifting their prices based on users, courses, and other factors."
"OutSystems is an expensive product. My company has to make monthly payments towards the licensing costs attached to the solution."
