WhatsApp is an online message application that nearly one-third of the world’s internet users operate. As of 2023, WhatsApp has almost 3 billion (Source: BacklinkO) unique users, with the expectation that this number will only increase with time. This means if WhatsApp goes down due to any issue, all the users will be affected directly. While such instances are rare, they still call for appropriate testing of the application. And every test relies on a well-defined and comprehensive list of test cases. So, here we list down the WhatsApp test cases that are essential to the proper functioning of the system.

Automating a WhatsApp Test Case

You are trying to log into a WhatsApp account using an invalid phone number, let’s see the error notification message you should receive and how to run that test case using Testsigma.

  • The first step is to create a Project to upload the .apk file of WhatsApp.

Whatsapp testing

  • Next, go to Uploads to browse and upload the application file under the new Project.

Upload file

  • Now is the time to create test cases for our example. Head over to Test Cases under the same Project and create test cases. Select the application apk file during test case creation.

Create Test case

  • Upon successful creation of test cases, Record or manually select the NLPs that correspond to your test scenario. For us, it is to check if the logging in operation using an invalid number would show the right error message. Below image shows the configurations you have to select while recording steps.

Record Test steps

  • This is what you will see next after clicking on Record. The left side shows the application and the right side will list down the test steps.

Testsigma recorder

  • Now, start using the application side as you would use it on a smartphone. Every interaction will be captured in the right side box. We ran the recorder and got the below final test steps for entering an invalid phone number.

Test steps

  • Finally, verify if you receive the error message for trying to login using an invalid phone number.

WhatsApp is an extensively used application, used by billions of people around the world every day. Nearly 11,574 messages are exchanged on the platform every second. This figure shows how even a second of downtime can cost the company a considerable loss and inconvenience to the users. Test WhatsApp thoroughly to avoid such instances. We bring you this blog that discusses the tests to run for the application. The idea is to cover as many test cases as possible, such as application settings, about sections, profile pictures, text exchanges, chat fields, and more.

What is a test case and test scenario with examples?

A test case is a detailed set of steps to be executed, inputs to be applied, and expected results for testing a particular aspect or functionality of a software application. A test scenario is a higher-level description of a particular functionality or feature to be tested. It encompasses multiple test cases and provides a broader view of the testing process. For example, a test scenario could be checking the login feature of WhatsApp, and test cases within this scenario would be verifying if an incorrect phone number prevents the user from logging in and if the correct phone number allows the user to log in.
