Mobile App Installation Testing: Ultimate Guide

Installation is a crucial aspect for the survival of any app. it doesn’t matter how well your app is working a minor flaw in installation sequence itself is enough for users to discard your app and never look back at it again. So, for the assurance, you need app installation testing.
Since we all believe in the saying that“Customer is the king” and “The first impression is the last impression”.
It is a must to keep our customers happy and leave a good impression on them. And thus it becomes very important to test your application for successful implementation to leave a good first impression on your customers.

So let us learn more about Application Installation Testing.
What is Application Installation Testing?
Application Implementation testing aka Application Installation Testing tests the successful installation of your mobile application across various mobile gadgets, models and operating systems.
Application Installation Testing is generally carried out before your application first interacts with its customers.
Application Installation Testing is the last phase of software testing life cycle (STLC).

Why should you do Application Installation Testing?
What if while installing your application, it corrupts the complete OS of user’s high-end mobile phone? FURY! Is all that you can expect.
To avoid such situations, it is a must that your application goes through an intensive round of Application Installation Testing.
Here are a few aspects that might help you apprehend the importance of Application Installation Testing.

  1. The first impression promotes the users to go deep into that thing and explore it. With an application, its implementation forms the first impression on its customers. Make sure your application is fit to be successfully installed by proper Application Installation Testing.
  2. Application Installation Testing makes sure that all the components of your application are entirely coordinated.
  3. Apart from Application Installation Testing, you cannot take application uninstallation testing lightly. After you uninstall the application from your hand-held device, it is important that all the related files are also deleted and application uninstallation testing ensures it commendably.

Type of Mobile Application Installation–Which one does your application supports?
Silent Installation: This kind of mobile Installation does not prompt any messages at the time of its installation. The related messages are saved in a log file.
Attended application installation: In attended mobile application installation, when you install your application; you are prompted and asked for various inputs. Few of the inputs that might be required from your end are:

  1. Accepting EULA/end user license.
  2. Entering the password is another input that you might be asked for.
  3. You can also be asked to give your input on various errors like internet connectivity issues.
  4. Some bigger applications can also ask you to use WiFi connection instead of mobile data for their installation.

Unattended mobile installation: In such type of installation you are not prompted during installation but if user intervention is required, it is done using an answer file where user mentions all the inputs that are required for installation.
Headless mobile installation/Network mobile Installation: Sometimes mobile networks install apps on their user’s mobile devices without having physical access to their devices. Such applications are installed from a network on a targeted mobile gadget.
Clean mobile Installation: In such mobile installation no older version of the application is installed, and it is being installed for the first time.
Automated mobile Installation: Such mobile installation is apt for applications where some prerequisite conditions are set and on meeting them the installation automatically starts.
Like for a few big applications user set a condition to be installed when the WiFi connection is on. When the application detects a WiFi connection on the gadget, it automatically installs it on the device.
Now when you know what type of installation does your application supports, its time to move on further.
Things to keep in mind before performing Application Installation Testing:

  1. Operating systems your application supports.
  2. Type of installation your application performs.
  3. The operating system on which you have to test your application.

How to perform Application Installation Testing?
Testing your application for proper installation is a must for a proper kick start of your application. Here are the steps that can help you carry out the testing properly.

  1. Check for an existing application and validate if your application checks for them too.
  2. Validate if installers draw all the instructions properly.
  3. Stop the installation process in between and check if the system returns to its original state.
  4. Manually check for the disk space and then validate if the application installer calculated the disk space appropriately.
  5. Confirm application responses for low disk space. Test if your application returns an appropriate error message when the disk space of your device is low.
  6. Test for registry changes that take place during the application installation process.
  7. Another important part that you need to consider isapplication uninstallation testing. After you uninstall the application from your hand-held device, it is important that all the related files are also deleted and application uninstallation testing ensures it commendably.

8 Formidable Challenges While Testing an Online Banking Application

Being the most complex and advanced enterprise solution, banking applications needs to be carefully considered in both functional as well as security aspects to ensure that customers and assets are protected from malware.
app testing
Internet-based electronic banking or online banking applications have become a necessity for customers. As a countless number of banking transactions happens every day, these apps need to have high level performance, with features that meets the  needs of a customer.
Few things that should be noted to constitute a consistent, bug-free, banking application:

  • The app needs a solid reporting system to keep track on daily transactions
  • Strong auditing is required to troubleshoot issues
  • It should have the capacity to adhere complex and advanced work flows
  • Banking apps should have the feature of integration with other apps such as Trading accounts and Bill-pay utility accounts
  • It should possess multi-tier functionality to support multiple user sessions

In this blog, we go through the key challenges faced while testing a Banking Application:
1) Strict Security Regulation: It is necessary for banking applications to protect customer data and private information as well as the assets. Therefore, during mobile software testing, these things should be considered by providing a secure testing environment.
A banking app should be compatible with  all operating systems, versions, devices etc. Along with iOS and Android, other versions including Blackberry and WP8 also need to be tested. Mobile testing tools that support both native and web properties should be used for wide usage.
To ensure that the software doesn’t have any flaws, the QA team needs to check both negative as well as positive sides of the system and report it before any unauthorized access happens. The bank should also use other security measures like an access validation code or one-time password for better safety. For security regulation testing, automation tools like HPWebInspect and IBM AppScan  should be used and for manual testing- Paros proxy, Proxy Sniffer, HTTP watch etc. should be put to use.
2) Complex Data: This is one of the major challenges that can occur while testing a bank application. No apps can  en sure that the back-end databases of bank system will not be affected by malware or all the data within is protected. So, it is necessary that the mobile testers need to have a pool of accounts that can be used for the testing solutions.
A bank definitely needs to have an automation tool to constantly check database connectivity and logical functions. It should be done over the virtual private network (VPN) to assure safety on its private data.
3) Active Support of Devices: About 80% of people spend their time on using mobile applications. Mobile manufacturers introduce new features on a daily basis to provide customers a better and friendly user experience. Similarly, banking apps also need to bring in revisions to offer a better experience on latest devices.
4) Privacy is Essential: Privacy plays a very important role in mobile banking. This feature defines how much secure a mobile banking app is for its users. Therefore, automated testing must be done for every single update to ensure protection for all private information. It is essential for a bank to have an automated tool system that run tests periodically without the need for a software tester to manually test each function within the app.
5) Real-time Activity: Apps should have the capacity to provide real-time updates and this is more challenging when it deals with network connectivity issues.
6) Proper Testing and Development: Bugs can affect any application and this is the reason your banking app should follow proper app testing procedure. Making  a banking application with user-friendly functioning and proper security checks require extensive revision and software testing.
7) Updated Market Trends: Consumer requirements and market trends keep changing invariably. Therefore, application features, usability etc. have to be revised and kept updated.
8) Performance Failures: Performance levels involve connectivity, infrastructure, and back-end integration. The transaction happening through the apps should be monitored at regular intervals. Also, Load and Stress tests must be performed regularly to ensure multiple support transactions on anytime.
Best Practices                                                                                                              
A few best practices that will help you manage certain challenges in testing banking applications are:

  • A clearly defined methodology of software performance testing
  • Testing that encompasses the complete work flow
  • Testing for functionality, performance and security
  • Testing of the app for UX, UI, data integrity and support multiple users

automation testing
Testing banking applications can be a complicated deal, but if the key methods and principles are placed right, then it can be beneficial with long-lasting advantages. The right blend of testers and processes are key factors of a successful mobile banking app.
