When performing sanity test on mobile application what all criteria should be taken into consideration

In the fast-paced world of mobile applications development, it is crucial to ensure that the apps we develop are reliable, user-friendly, and free from critical defects. One way to achieve this is by conducting a sanity test on the mobile application before its release. A sanity test, also known as a smoke test, is a high-level test that aims to verify the basic functionality of the application. In this article, we will explore the key criteria to consider when performing a sanity test on a mobile application.


As the mobile app market continues to grow exponentially, users have come to expect seamless experiences from the applications they use. To meet these expectations, it is essential to conduct thorough testing, including sanity testing, which ensures the basic functionality of the app is intact. By considering various criteria during the sanity testing process, developers and testers can catch potential issues early and deliver a high-quality mobile application to the end-users.

Understanding Sanity Testing

Sanity testing, also referred to as smoke testing, is a subset of regression testing that focuses on quickly checking the fundamental features of the application. The goal is to identify major flaws or defects that could hinder the app’s basic functionality. It is typically performed after the completion of a software build or integration of new features. Sanity testing helps verify if the app is ready for more extensive testing and subsequent release.

Criteria for Performing Sanity Testing

When conducting a sanity test on a mobile application, several critical criteria should be taken into consideration. Let’s explore each of these criteria in detail:

a) Installation and Launch

The installation and launch process of the application should be smooth and error-free. The app should install without any issues and launch promptly, allowing users to access its features effortlessly.

b) Navigation and User Interface

A mobile application should have an intuitive and user-friendly interface. Testers should evaluate the navigation flow and ensure that users can easily understand and navigate through the app’s various screens and features.

c) Core Functionality Testing

The core functionality of the application must be thoroughly tested during the sanity test. This includes verifying that key features, such as login, registration, search, and basic interactions, are working as intended.

d) Network Connectivity

Mobile applications often rely on network connectivity to fetch data or interact with web services. Testers should ensure that the app behaves gracefully in scenarios of weak or intermittent network connectivity, displaying appropriate error messages or fallback options.

e) Performance and Responsiveness

The performance of the application plays a crucial role in delivering a satisfactory user experience. Testers should evaluate the app’s response time, loading speed, and overall performance to ensure it meets acceptable standards.

f) Battery Consumption

Mobile devices have limited battery life, and users expect apps to be efficient in their power consumption. Testers should assess the app’s impact on the device’s battery life and identify any excessive battery drain that could negatively affect the user experience.

g) Compatibility

Mobile applications are designed to run on various platforms and devices. It is essential to test the app on different devices, screen sizes, and operating systems to ensure compatibility across a wide range of configurations.

h) Error Handling

Error handling is a critical aspect of any mobile application. Testers should examine how the app handles errors, such as input validation failures or network timeouts, and ensure that appropriate error messages are displayed to the user.

i) Security and Data Privacy

Mobile applications often deal with sensitive user data. Testers should verify that the app follows best practices for security and data privacy, such as encrypting sensitive information and implementing secure communication protocols.

j) Usability Testing

Usability testing helps evaluate the overall user experience of the application. Testers should focus on factors like ease of use, clarity of instructions, and the overall intuitiveness of the app’s features.

k) Localization and Internationalization

If the mobile application targets a global audience, it should support localization and internationalization. Testers should verify that the app displays content correctly in different languages and adapts to various cultural preferences. For example Chicago app developers should abide by Illinois state laws at all times.  

l) Documentation and Help

Clear and comprehensive documentation and help resources are essential for users to understand the app’s features and functionalities. Testers should assess the availability and quality of documentation, ensuring it is easy to access and provides accurate information.

m) Integration Testing

Integration testing ensures that the mobile app works seamlessly with external systems, APIs, or other third-party components. Testers should validate the integration points and interactions, checking for proper data exchange and error handling.

n) App Store Guidelines Compliance

For applications intended for distribution through app stores, compliance with the respective app store guidelines is crucial. Testers should ensure that the app adheres to the guidelines set by the target app store, covering aspects like content policies, user interface requirements, and security guidelines.

o) User Acceptance Testing

User acceptance testing allows real users to evaluate the app and provide feedback from their perspective. Testers should consider incorporating user acceptance testing as part of the sanity test to gather valuable insights and identify any usability or functionality issues.


In conclusion, conducting a sanity test on a mobile application is a vital step in ensuring its basic functionality and usability. By considering the outlined criteria during the sanity testing process, developers and testers can identify potential issues early on, address them promptly, and deliver a high-quality app to the end-users. Remember, an app that passes the sanity test stands a better chance of meeting user expectations and achieving success in the competitive mobile app market.


Q1: How is sanity testing different from other types of testing?

A1: Sanity testing focuses on quickly checking the basic functionality of the application, whereas other testing types, such as regression testing, aim for more extensive coverage of features and scenarios.

Q2: Can sanity testing replace comprehensive testing?

A2: No, sanity testing is a subset of testing and should be complemented with other types of testing, such as functional testing, performance testing, and security testing, to ensure thorough coverage.

Q3: When should sanity testing be performed?

A3: Sanity testing is typically performed after a software build or integration of new features to quickly verify the app’s basic functionality before proceeding with more extensive testing.

Q4: How long does a sanity test usually take?

A4: The duration of a sanity test depends on the complexity of the application and the number of features being tested. It can range from a few minutes to a few hours.

Q5: Can automated testing be used for sanity testing?

A5: Yes, automated testing can be employed for sanity testing, especially for repetitive or routine checks, to save time and effort during the testing process.
