How to Test a Food Delivery Application like Zomato

Back when delivery applications were still not a reality, people visited restaurants to buy food. But delivery applications changed everything. Life has so many conveniences because of them.

Now with smartphones, food is delivered by performing a few taps. Delivery applications like Swiggy and Zomato save time and money as they offer various discounts and offers. Food delivery applications help one to order food when one is hungry or there are no available food options.

Post-Covid we have noticed that there is a magnificent rise in online orders hence testing of these food delivery applications is now very important. If you are not clear about how to test a food delivery app, read on.

Let’s first look at the types of testing for food delivery/ restaurant applications.

Functional Testing of Food Delivery Applications

Functional testing of food delivery applications is very important to make sure that the applications fulfil the acceptance criteria by the product owners.

Functional testing includes various use cases such as:

  • installing and updating of food delivery application,
  • all fields and functionalities should work as per requirements,
  • the behaviour of the application when there is a new message or phone call
  • behaviour of the application when there is a lack of internet
  • verification of error messages when something is wrong with food delivery application
  • verification that the application should not consume too much memory and space, etc.

Also, other functional use cases include validation of different payment methods, validation of integration with third-party applications for sign-in and payment such as Google. Quick ordering functionality such as repetition of past orders, push notifications, validation of delivery executive location, validation of application behaviour when the network connection is switched between 2G,3G, and 4G, and validation of different voice control prompt.

Performance Testing of Food Delivery App

Performance testing is a very crucial part of testing food delivery applications. We need to evaluate the behaviour and stability of food delivery applications when high stress, load, concurrency, volume is applied.

Different performance testing use cases are

  • validation of application behaviour under high load
  • validation of application behaviour under peak usage
  • validation under high constant load and identification of various bottlenecks in the application

Some other use cases are optimization of various APIs, validation of response time of APIs, hardware, and resources utilization under high load. These validations need to be performed so that the food delivery app can become robust enough to handle any amount of load.

Usability Testing of Food Delivery Applications

It is done to make sure that customers are satisfied with the application experience. The design of the food delivery app should be very easy and user-friendly because the major chunk of the population which uses Zomato or Swiggy isn’t highly educated. Simple and effective design is the key to reach to a high number of customers.

Some usability use cases for food delivery applications are

  • making sure that functionalities are easy to find
  • navigation should be easy and user-friendly
  • buttons of the application should be visible
  • verification that font should be of appropriate size so that anyone can read them
  • verification that the user can undo the last operation and finally
  • the design of the application should be appealing, simple, and user-friendly

Some other use cases are validation that the registration process for food delivery apps should be very simple so that anyone can register and start using it. Addition of address should be very simple, menu navigation should be intuitive and hassle-free, validation that right images should be displayed against food items, images should be clear with proper colors.

Validation that offers and promotions should be easy to find, Bill should be understandable, delivery time and location should be easy to find, making sure that rating process is user-friendly and finally, the checkout process should be damn simple.

Compatibility Testing of Food Delivery Applications

This type of testing verifies that the food delivery application works well in different environments like OS: iOS and Android. Food delivery applications should work fine on all mobile devices with different operating systems and with different sizes. We also verify that it works well with high configuration and low configuration phones.

This is very important testing as a little bug here and there can cost lakhs to business. Hence, Compatibility Testing should be done by a larger set of people who have access to many devices to ensure that the application is compatible with all of them. A testbed of devices and configurations needs to be maintained for proper compatibility testing.

Security Testing for Food Delivery Applications

Security Testing is very important so that the personal data of customers should not be at stake. It is done to ensure that customer data is protected against all kinds of threats and attacks. Leakage of data can cost hefty fees to the business.

Some of the use cases of security testing are validation of application behaviour under cyber-attacks, validation that application should now to access the application without proper authentication, and validation of session timeout in times of inactivity.

Food delivery applications have integration of customer credit cards and other card data so security testing becomes very important otherwise customer data can be leaked.
