Publishing applications or websites is easy with Microsoft IIS. You don't need external software or complicated tutorials involving command lines and editing configuration files. On other hand, sometimes the troubleshooter needs a high knowledge of Windows Server, Registry, and tools to debug the application. If you need to host non-Microsoft technology as PHP pages or have a low budget, I recommend IIS equivalent software as Apache.
When you have to test the UI and how it behaves when certain actions are performed, you need something that can automate the browsers. This is where Selenium comes to the rescue. If you have to test APIs and not the frontend (UI), I would recommend going with other libraries that support HTTP Requests. Selenium is good only when you have no choice but to run the steps on a browser.
A big advantage that we use all the time is reviewing the logs that automatically get generated in IIS. It has helped us troubleshoot various problems in our applications over the years.
IIS integrates really well with Visual Studio and TFS. We are able to quickly deploy new applications and changes to applications when requested by the business.
IIS has proven that it is easy to configure and maintain with minimal effort.
Selenium is pretty user-friendly but sometimes tests tend to flake out. I'd say roughly one out of twenty tests yields a false positive.
Selenium software cannot read images. This is a minor negative because a free plug-in is available from alternate sources.
Slowness may be a minor factor with Selenium, though this is an issue with basically any testing software since waiting on a site to execute JavaScript requires the browser to wait for a particular action.
We have no intention to replace all applications running on top of the IIS platform. Not all applications support other platforms and not all support staff are skilled in Linux/Apache platform support. Whereas IIS may not be the best performing or most secure web platform available, for the aforementioned reasons, it is impossible not to continue use of this product.
We love this product mainly because of its high customization abilities and the ease of use. Moreover, its free and can be learned easily through online communities and videos. The tests are more consistent and reliable as compared to Manual tests. It has enabled us to test a large number of features all in one go, which would have impossible through manual tests. The reports generated at the end of the tests are really helpful for the QA and the development teams to get a fair view of the application.
As I've mentioned earlier, Microsoft IIS is very simple and easy to use. The user interface is a little bit overloaded with a huge number of different options, but once you have a little clue of what you are doing and what you need - no issues at all.
For those who are unfamiliar with coding, there is a bit of a learning curve. There is plenty of helpful documentation and resources but it can take a little time to get the software up and running. Once you get the hang of how Selenium works, and what it can do, you realize how many things you can use it for, and how many processes you can automate.
ARR (application request routing) in Microsoft IIS Server enables the web-admins to increase the web app reliability and availability through the rule based routing and load balancing of HTTP requests which in turn provides highly available server. IIS 7.0 Manager also provides kernel as well as user mode caching for faster performance and in case if the server fails, the IIS server has good amount of details logged in its log files which help understand and debug the cause quickly. Load balancing facilitates IIS server to fight against availability issues.
In my experience, I have never had significant issues with IIS performance. Sometimes I've experienced issues with loading time, but it is mostly related to the web site code. However Amazon, Microsoft and Google providing free cloud services with very limited resources, and in that scenario, "heavy" websites on IIS could be the issue. In other situations - performance is good.
As mentioned earlier there is so much documentation or guides or stack overflow questions out there that someone will have faced the same or very similar scenario to what you are going through that you will almost certainly find a solution to what you are after.
The Selenium app has a pretty fat community of users. For the problems we are experiencing, we are primarily receiving support from these communities. In addition, there is widespread service support. Instant support is given to the problems we experience when we need Online support. We and our team are happy to provide this support, especially before important deployment processes
We did everything we needed to use it. Now we can execute our tests on different operational systems and browsers running few tests simultaneously. We also implemented Appium framework to execute our tests on mobile devices, such as iPhones, iPads, Android phones and tablets. We use SauceLabs for our test execution and Jenkins for continuous integration.
Apache is java. Java is unnecessary complex. No developer wants to invest in learning all the hundreds of text based configuration files to get something done. Also, apache gives you the most evil and un-usable user interface possible. [Microsoft] IIS makes [life] after development easy, which is already complex enough to be bothered by something as mundane as exposing your work over the internet.
At the time of adoption, there were not many other alternatives that were even close to being competitive when it comes to browser testing. As far as I know now to this day, there is still little competition to Selenium for what it does. Any other browser-based testing still utilises Selenium to interact with the browser.
Microsoft IIS Server is scalable if the underlying server configuration is done correctly. Use x64 edition v/s 32bit and using 32bit mode application pools are some of the tweaks to be done to make the IIS server scalable. There are too many small configurations need to be carried out in order to make a highly scalable IIS server hence not giving full score in this area.
