Everything You Need To Know About App Testing

Introduction

Software testing, to put it simply, is the process of ensuring that your software application (web/mobile) is of the finest quality and that all of its features and capabilities operate as intended, are bug-free, and provide the best possible user experience. With innumerable apps releasing in the market, has given rise to web and mobile application testing. You may test your applications using a variety of testing techniques. To better comprehend it, let’s look at some fundamentals of testing software applications.

Different types of Software Applications:

• Web applications
• Desktop Applications
• Mobile Applications- Native Apps, Hybrid Apps, and PWAs.

We can use various testing techniques for all of the aforementioned categories of software applications. As we continue reading this post, let’s learn more about them.

Manual vs Automated Testing

Application Testing can be manual or automated. Manual testing does not involve any automation tool to execute test cases. Instead, it involves human testers who perform usability, performance testing, etc., to ensure software meets the quality standards. In manual testing, after the entire development is completed, a bug report for the full code is compiled and given to the developers for review and correction. Some manual testing includes exploratory testing, manual regression testing, and test case execution. In the early stages of development, manual testing is typically done to verify specific features in the application.

Automated testing eliminates human error from the testing process and makes it simpler and more productive for the QA team. The tools evaluate application performance automatically from the end-user perspective, saving the tester time and effort. Functional testing, integration testing, acceptability testing, API testing, unit testing, and automated regression testing, are a few types of automated testing.

Functional and Non-Functional Testing

Functional testing validates every functionality of the software application. It tests all core features of the app, its usability, and user accessibility. It also checks to see if the app shows the appropriate error messages when an error occurs. It intends to focus more on the software behavior than the app source code. It includes:

 Unit Testing: to check each software component as a separate unit and ensure that they behave as required.

Integration Testing: to check each software component as an integrated unit and ensure that they behave well when integrated with a group.

System Testing: to validate how compliant the software is or how well the individual components interact together in a fully integrated system.

Sanity testing: To ensure that any modifications or code changes in the build haven’t affected any already-existing functionalities and that the application is functioning as it should after the changes. The build is rejected for additional testing if the sanity check is unsuccessful.

Smoke testing: It runs before any functional or regression testing is carried out and only checks the fundamental components of the applications, such as login and logout, and not the entire application. Build Verification/Confidence Testing is another name for it.

Interface testing: to check how well two different software systems (interfaces), and two components are interacting with each other.

Regression testing: It is performed to check if any new feature additions have not impacted any of the existing app functionalities. Regression tests are run to determine whether the old functionalities continue to function properly following such changes. It is one of the most critical forms of testing. Cross browser testing consists of many redundant test cases. Here regression testing becomes mandatory.

Beta Testing: It is also known as user acceptance testing and it is carried out by actual users to determine how well they have accepted the finished product (application). The users’ feedback thus received becomes crucial information for making product enhancements.

Non-Functional Testing

Performance Testing: Performance testing involves evaluating how well an app performs under various conditions, such as device and network instability, slow loading speed, low battery condition, location changes, etc., to identify and promptly fix any performance-related issues.

Load testing: to check how the app behavior and performance in different workloads and high traffic situations.

Stress testing: It monitors when the system crashes or how frequently errors occur in a stressful condition in order to assess an application’s capacity to retain performance effectiveness even under challenging circumstances.

Compatibility testing: to check the application compatibility with different environments. In the case of a web application, the app’s compatibility with various devices, browsers, and operating systems is examined.

Security Testing: To uncover the application vulnerabilities, and threats to prevent security breaches and malicious attacks.

Apart from the above mentioned, there are many other forms of testing performed to achieve quality, speed, and deliver best user experience to the customers.
