Nowadays apps become even more critical to businesses’ success. Companies that admit this tendency and take actions to make the quality, security and usability of their applications main priority will gain a huge advantage. We gathered here the main tips that will help you to test your app successfully.

What functional issues of the app should be tested carefully?

The majority of users hope your app will load within a couple of seconds. If your app doesn’t launch fast enough, users will find an option and many will never return. And this will have negative effect on a user’s general opinion of your brand. Do you want such consequences? Don’t think so. Pay special attention to these key areas:

  • Sign Up and Login: if your app requires a password and user name, pay close attention to the fields and make sure it’s easy for users to enter their information;
  • Menu Options: make sure menu items like Help, About, etc. are easy to find, navigate and select;
  • Actions: any problems related to scrolling, selection, the back button, etc. may lead to trouble;
  • Connection Speed and Carrier: make sure your basic tests cover the most likely carriers;
  • Screen Size: make sure everything look good and work correctly on a range of screen size;
  • Interruptions: test how your app works when interruptions like battery power, SMS, MMS and video calls occur;
  • Error Messages: your error messages should be clear, concise and actionable in the eyes of the everyday user.

Testing aspects

So pay your undivided attention to such sides of testing as functional testing, usability testing, load testing, security testing and localization testing. Let’s dwell upon each of them.

Functional testing

Functional testing is performed to verify that a software application performs and functions correctly according to design specifications. During functional testing the crucial application functions, text input, menu functions and installation and setup are usually checked.

Typically, functional testing involves evaluating and comparing each software function with the business requirements. Moreover, functional testing also checks the software for usability, such as by ensuring that the navigational functions are working as required.The goal of functional testing is to validate the behavior of an app.

When you start testing app functionality, test early and test often – combine automated and manual testing to cover your app from every side. It is extremely important to test the functionality of your app on a line of devices. And don’t forget regression testing any time you change, remove or add a feature. Use the app like if you were a new user, disclosing potential problems.

Usability testing

The aim of usability testing is to see if a user can complete the tasks they are considered to complete. A good user experience can be ruined by a number of issues:

  • Layout and Design. Pleasant layout and design let a user to perform tasks easily. Don’t offer so many features or content that your app is hard to navigate. Everything should be easy to see and interact with on a small screen.
  • Functionality. A mobile application must give the user the corresponding functionality. If the functionality of an application looks unfinished or insufficient, customers may be lost.
  • Interaction. The flow of an app must be natural and interactions should be easy. For example, if a button is placed in the perceived ‘wrong’ location, users can become upset and leave the application. If links are too close together, they’ll be difficult to select.

Load testing

Load testing is another critical step in the successful launch of your app. If the app’s performance is slow, users will likely go to other apps and services.

  • Outside variables. Be aware of mobile carriers and data usage, which can influence the speed and performance of the app.

load testing

  • Mobile web. Users expect mobile websites to respond just as quickly as traditional sites. Be careful that your mobile site isn’t so bulky that it’s slow to load and react.
  • Access from anywhere. Mobile apps can be used anywhere. Consequently they need to be tested with various devices and carriers depending on the region to guarantee a consistent experience and load time.

Security testing

The vast mobile development introduces completely different security challenges. While most of the security tools and practices for traditional web and desktop applications can be also applied to mobile, there are some unique concerns to remember including lost or stolen devices, mobile malware, data leaks, encryption and more.

security testing

Are you ok with the following questions:

  • Confidentiality: Does your app keep private data private?
  • Integrity: Can the data from your app be trusted and verified?
  • Authentication: Does your app verify that users are who they say they are?
  • Authorization: Does your application properly restrict user privileges?
  • Availability: Can an attacker take your app offline?
  • Non-Repudiation: Does your app keep records of events?

Localization testing

Making sure that your app isn’t the gateway for a hacker is critical for you, your reputation, your users and your company. When testing, make sure your privacy policy and information about processing user data is easy for the users to find and understand. Without proper localization, companies can exclude, offend or mislead entire lots of users. Your app should be reviewed by native speakers or people who know the local area not to miss important mistakes.

Your localization testing should regard factors such as:

  • Content: Static and dynamic content like catalogs, search results, metadata
  • Dates: Is the date January 1 or 1 January?
  • Characters: Différent länguages have ðifferent set∫ θf characters
  • Postal codes: In some countries, postal codes include letters
  • Phone numbers: Different formats for different markets
  • Direction: Some languages are written left to right, others are right to left
  • Currency conversion: Especially important for retailers
  • Tax calculation: VAT, sales tax and others vary from country to country
  • Cultural context: Words and phrases may be technically translated correctly, but they could have a different implied meaning in another culture.
