Test Cases For Mobile Application Testing

Test Cases For Mobile Application Testing / mobile app test cases: When testing a mobile application, choosing the right test cases is important. This means choosing correct test cases based on the app’s requirements, target audience, and user persona. Writing effective mobile app test cases is essential to ensure the app works properly. Test cases and test scenarios are two different things. Test scenarios are a broad overview of what needs to be tested, while test cases are specific instructions for testing something.

Writing test cases is important to ensure the optimum functioning of any application. The test cases that are written by a team are typically categorized per different levels. This is done to ensure that there are no duplicate efforts of a team being invested in a single function.

The levels of writing test cases are:

  • Level 1: This level includes the writing of test cases that are based on the available information about the product’s specification and user documentation
  • Level 2: Considered to be a practical stage, this level includes writing test cases based on the application’s actual functional and system flow.
  • Level 3: Some test cases are grouped to write a test procedure at this level. Test procedure refers to a group of small test cases and can include 10 test cases.
  • Level 4: The process is automated at this level. This helps minimize the human interaction with the system, which enables the QA to focus only on currently updated functionalities to test

Tips to Write Test Cases for Android Applications

Writing a good mobile app test case template is easy. However, it just requires hard work, determination, and clear focus. Some of the simple tips to write sample test cases for Android mobile applications include:

Mobile app test cases should be written in such a way that they allow a person to test only one feature at a time

  • One should not overlap or complicate test cases.
  • Cover all the positive and negative probabilities of the test outcomes
  • Write in simple language with exact and accurate names of forms, fields, etc.
  • Android developers should ensure they continue to create test cases when the application code is still in the writing process.
  • Test cases should be stored in version control along with the source code
  • The focus should also be on continuously integrating the new test cases.
  • Tests should be run every time the code is changed
  • Avoid using emulators and rooted devices

What to test in mobile applications?

There’s no one-size-fits-all answer to this question, as the test you should run will vary depending on the type of mobile application you’re developing. However, some general tests that may be relevant for different types of applications include:

  1. User engagement – This test measures how well the application engages users and measures engagement metrics such as time spent on the app, number of visits, and click-through rates.
  2. Navigation – This test checks how easy it is to navigate the application and whether any links or buttons are hidden or difficult to find.
  3. App performance – This test checks whether the application loads quickly and whether there are any crashes or other issues.
  4. Security – This test checks for any vulnerabilities in the application that hackers could exploit.

Mobile App Test Cases

Mobile applications are an important part of the modern world. They are omnipresent and can be used for everything from taking selfies to learning languages. However, when it comes to mobile apps, a wide variety of formats must be tested to ensure they will function properly on all devices.

In mobile apps, test cases are used to check for bugs and errors. Manual test cases for Android applications can be helpful in different scenarios, such as in-app purchases, location, messaging, and notifications.

Conducting functional testing for mobile applications is the fundamental activity of assessing that every feature in the application is responsive and working as expected.

Questions that arise when stating Mobile Application Functional Testing would usually be:

  • Can the target user perform this task?
  • Are all the features working as expected?
  • Are the features well integrated?

Since Functional Testing is based on requirements, test cases are designed for every feature and their integration. These test cases are expected to be run for each update release of the mobile application (Basic features can be automated to ease the job).

The article will focus on basic Functional Testing that is expected to be performed (most of them) on any mobile application.

Steps for Mobile Application Functional Testing

Before performing functional testing, follow the below steps:

  • Identify the functionalities that have to be tested for the application
  • Prepare the input data required for the functionality
  • Determine the expected output for the functionality based on specifications
  • Design the functional test cases for the functionalities identified
  • Execute the functional test cases on the specified build for the application
  • Evaluate the functional test results of each of the test cases for accuracy

In case of feature updates, modify the existing test case to match the latest specifications and keep the test cases compliant with requirements.

Mobile Application Testing – Basic and General Validations

Testing the Mobile Application depends on various factors:

  • Who the target audience is – Consumer, Entrepreneur, etc
  • Category of the application – Banking, Business, Education, Games, Lifestyle, etc
  • Mode of distribution of mobile application – Google Play Store, Apple App Store, Direct distribution through SDKs

Most of the below-listed tests for any mobile application can be performed as Functional Testing.

  • Verify whether the mandatory fields are validated for correctness. They should be provided value by the user before submitting.
  • Verify whether the mandatory fields are well distinguishable from non-mandatory fields.
  • Verify whether the application functionalities meet the business requirements (test cases should be well designed for this case)
  • Verify that the application does not run into chaos in case of interruptions. For example, if there is an incoming call while the application is being operated, the application should go to the background. Upon the end of the call, it should come to the foreground and remain active.
  • Verify whether the mobile device can send, receive, and store the content of other applications while the application is being run. For example, the mobile device should be able to send and receive messages, should be able to handle push notifications of other applications, etc.
  • Verify whether the mobile device’s multi-task mode supports the application to be operated in the mode. For example, if the mobile device supports a split window so that two different applications can be run, verify whether the application can be run along with any other application available.
  • Verify all the navigations within the application.
  • Verify the sharing feature through the application. For example, if the application supports users to share content, verify the sharing functionality for all the options supported by the mobile device – Messengers, Drive, Mail, etc.
  • Verify all the modes of payment transactions that the application supports. For example, if the application supports Debit / Credit Card, Online Payment, and Paypal, validate the transaction through all the modes.
  • Verify the application’s integration with other common applications. For example, if the payment transaction is successful, the application should send the notification with the supported mode (message or mail), supporting notifications.
  • Verify that the page scrolls are adequate and that later parts of the page load correctly and on time.
  • Verify the number of rounding errors is minimal.
  • Verify all the error messages related to the network. For example: “Error: Network unavailable.”
  • Verify the application does not interfere with other application’s functionality and consume their memory.
  • Verify the application’s resume if it was suspended due to unexpected issues: system failure, hard reset, etc.
  • Verify that the application download and installation is free of significant errors and that the device meets the system requirements for the application to install and run (like space, permissions, etc.)
  • Verify that starting the application is consistent with every use
  • Verify the application behavior on the major devices and different combinations of carriers: 2G, 3G, and 4G
  • Verify the application and user manual compliance. Both should match and be consistent.

It is very much required to perform the entire functional test regression suite for any mobile application every time before launching to the market, be it the new application or the updates to the existing one. This uncovers the new functional issues and helps in delivering quality applications. The listed validations for Mobile Application Functional Testing can be considered as the checklist for any application.

Mobile Application Functional Testing should cover all features’ positive and negative scenarios. For positive scenarios, include the tests where the user can achieve the goal—for negative scenarios, including the tests that display error messages, highlighting the wrong actions and failure to reach the goal. Let’s take a look at some simpler examples.

Mobile Application Testing  – Positive Validations for Login / Logout feature

  • The registration link should be functional.
  • Users should be able to register by providing values to only mandatory fields.
  • Users should be able to register by providing all mandatory field values.
  • Activate the account with supported modes: Phone number or email
  • Once registered and activated, log in with registered details (say email address and password)
  • Logout from the application
  • Successful Password reset through the supported modes: Phone number or email.

Mobile Application Functional Testing  – Negative Validations for Login / Logout feature

  • Register with already registered account details
  • Register, leaving a few or all the mandatory fields blank.
  • Register with values in non-supported format for fields (Incorrect format for an email address, password non-compliance, etc.)
  • Try logging in without activating the account
  • Try activating after the activation link/code expires
  • Once registered and activated, log in with invalid details (invalid email address and invalid password, invalid email address and correct password, correct email address and incorrect password, either of the fields blank, and both the fields blank)
  • Password reset failure due to non-compliance, repeating old passwords, etc.

This way, the tester should be able to create tests for Mobile Application Functional Testing effectively. Functional Testing is the means to gain confidence in the application’s behavior and usage.

Test Cases For the Mobile Number Field

A mobile number field is a text box on the mobile or website that accepts text input. The purpose of a mobile number field is to receive custom SMS messages and SMS-based requests from the user without requiring them to log in or manually fill out an email address.

The mobile number field is an important part of phone numbers. It holds the digits of the mobile number and some special characters to make it unique.

  • Verify that the mobile number field should display the accepted format of the mobile number as the placeholder text for user assistance.
  • Add a valid mobile number and verify that the field accepts the correct one.
  • Verify whether the user can copy and paste the mobile number in the field.
  • Verify that the Mobile number field should accept only the numeric value by entering alphabets.
  • Verify that the Mobile number field should accept only the numeric value by entering the special character.
  • Verify by entering a number less than the actual mobile number.
  • Verify the behavior by adding more digits than the actual mobile number.
  • Verify that the field accepts the space (s) between the mobile number or not according to the requirements.
  • Verify an error message shown for the blank input for the Mobile Number Field.
  • Verify by adding only the spaces in the Mobile Number Field.
  • Verify whether the correct mobile number is saved in the database by clicking the Save or Next button.
  • Verify that the mobile number is saved by pressing the enter button after adding the mobile number in the field.
  • Verify whether country flags are shown with the Mobile Number field or not.
  • Verify whether the flag’s country code is shown with the Mobile Number field.
  • Verify the mobile number text field by entering the valid 10-digit mobile number, i.e., “9878775858”.
  • Verify the mobile number field by entering a Less than ten-digit mobile number, i.e., “898585858”.
  • Verify the mobile number field by entering more than 10-digit mobile numbers, i.e., “58585858585”.
  • Verify the mobile number field by entering the blank space between the number, i.e., “8585 85858.”
  • Verify the mobile number text field by copying and pasting the mobile number .it must be copied and pasted into the text box.
  • Verify the mobile number field by entering the 10 “Zero” in the text box, i.e., “0000000000.”
  • Verify the mobile number field by entering only ten blank spaces.
  • Verify the mobile number field without entering any value.
  • Verify the mobile number field by entering the special character
  • Verify the mobile number field by entering the character value.
  • Verify the mobile number field by entering the “0” initially.
  • Verify the asterisk symbol for the mobile number if the field is mandatory.
  • Verify the alert message when the user clicks on save without entering the value in the mobile number text box while it is a mandatory field.
  • Verify the alert message when the user enters the wrong data in the mobile number field. (Eg. Mobile Number, mobile number with character and special symbol, Blank field, etc.)
  • Verify the placeholder for the mobile number text box.
