Beginners Guide to Web Application Testing

Web applications are designed to make our everyday tasks easier. Some are created to add more spice to our lives. Users choose applications for many different reasons. One thing is the same for all though: all users expect a lot when it comes to the experience of interacting with applications. This puts pressure on developers to produce apps that work well and satisfy users.

It is not enough that you produce awesome applications that capture your users’ hearts. Since apps are there to help, they must perform to its maximum potential before they are released to users. It must then undergo a series of tests that check each aspect of the application. This is called Web Application Testing. It ensures that the application runs the way it is supposed to run in order to give the users an unforgettable experience.

Each application has unique features. Web Application Testing tests all these through broad concepts that encompass everything the app needs to satisfy the users. The following are the important concepts that have to be understood when giving the app a test run:

  1. Functionality
    Once a user chooses an app, he expects to get satisfactory results. The app should be in perfect working condition. Meaning, it has to function well consistently. All fields must accept input and submissions should work correctly. If an invalid input is made, error messages should be appropriate and redirect the user to the right action. Dead pages or invalid directs are no-no’s because they are big turn offs.

    You must also test the efficiency of your app at computing and displaying results. For apps with interactive media, the animations and audio must work smoothly so as not to interrupt or slow down the entire app while it loads. These animations are made to entertain and impress, not to be an inconvenience.

    The app’s functionality also includes how notifications and updates will be displayed or communicated to the user. The administrators’ dashboard should be functioning well in case the user needs help in the future.

  2. Usability
    Some apps may look rather difficult to handle. When you test your app, you have to ensure ease of use. You don’t want your user to spend more time being frustrated with the app than actually enjoying it. The content must be friendly for anyone, whether they are first time users or tech savvy. In order to help the user get the most out of the experience, navigation from one page to another should come easy using controls that can be understood immediately.
  3. Interface
    Appearance can be everything for some when it comes to finding the right app for their own purpose. Once a user gets turned off with how the data is arranged on the page, he may never want to use the app again, pushing him to find another one. The interface shows how the text and visuals are arranged on the page. These have to be displayed properly and in right order. They must be organized in a way that the features are accessible on the page. The terms used must be crystal clear so it won’t be confusing for the user.

    It must also ensure that data flow is smooth from one page to another. All links should be prominent, especially the link that points back to your homepage. Support channels should also be working properly and can easily be seen on the page in case users encounter a problem or in case they need a guide.

  4. Compatibility
    People not only browse through their desktop computers. Not everybody uses the same operating system or browser. Compatibility testing ensures that the application will work well in different venues. This includes display and data flow. When you do compatibility testing, think of as many scenarios that can happen in your users’ environments so you can find a solution to make them work properly in as many venues as possible.

    Some apps though were made to be compatible with only a certain browser or operating system. You must then make sure that your app degrades gracefully to still provide a great experience for your user who is using a different medium.

  5. Performance
    Your app may work differently in certain situations. There are times when some applications slow down when the load reaches or goes beyond maximum capacity. Server response time should then be tested to ensure that the app will not slow down or crash. Limits are tested over a period of time to check for the endurance of various elements that comprise the app. You may now find solutions in case something goes wrong during overload. Tools like PageSpeed Insights and GTmetrics can help you analyze and resolve those performance issues.
  6. Security
    Web apps capture a lot of data from users. Personal information, financial and work details will have to be protected because users trust you with these. Your app should keep these information private and protected from unauthorized users. Access to these data should be limited at all times, but if access is necessary, authentication should be done first.

    Your number one enemy when it comes to ensuring the security of your app are hackers. Their methods include finding any vulnerability in your codes or system. It helps to be familiar with their ways so you can identify what needs to be double checked before you release your application.
