Application Testing Tutorial (What is, How to, Tools)
What exactly is application testing?
Application testing is a sort of software testing that is carried out using codes with the goal of detecting faults in software. It is concerned with testing the complete application.
It aids in improving the performance of your products as well as lowering expenses, increasing ROI, and shortening production time.
Application testing may be conducted in several areas such as GUI, functionality, database (backend), load test, and so on.
The testing phases for application testing comprise stages such as requirement analysis, test strategy, test analysis, test plan, test execution, and issue management, among others.

Techniques for Application Testing
Software applications and solutions differ in areas like the attributes they provide and the operations they perform. As a result, application testing assures that certain software or application works effectively.
Application testing has four stages in its entire life cycle
Create test plans depending on the application's needs.
Create manual test cases as well as automated test scripts.
Carry out functional tests to check the application's objectives.
Run load testing and fine-tune application performance.
Application testing is divided into two categories.
Testing of Web Applications
Testing of Desktop Applications
| Application Testing | Types of Testing |
|---|---|
| Web Application Testing |
|
| Desktop Application Testing |

| Mobile Application Testing |

Techniques for Application Testing
Testing techniques are a distinct way to ensure that a software program has been thoroughly tested. An unorganized and ineffective testing technique might result in an unreliable output.
There are three methods for doing testing.
Testing with a Black Box
Testing in a White Box
Testing in a Grey Box
Testing with a Black Box
The Black Box Testing approach is extensively used for functional, non-functional and regression testing. The strategies utilized in black box testing are −
Testing for Equivalence Classes
Testing Boundary Values
Testing of Decision Tables
Tables of State Transitions
Testing in a White Box
White box testing is commonly used to evaluate the program code for internal security breaches, faulty or badly constructed routes, conditional loop capabilities, and so on. The strategies utilized in white box testing are −
Assessment of Code Coverage
Coverage of the Path
Testing in a Grey Box
This testing method combines both Black Box Testing and White Box Testing. It is conducted in compliance with the intent of detecting defects caused by inappropriate structural or application usage.
Application Testing Test Strategy
The Product Information, Software Requirement Specification SRS, or Use Case Documents are used to create the Test Documentation. The test is concerned with what to evaluate, how to check, when to verify, and who will check. The test plan document serves as a means of interaction between the test team and the test management.
A common application testing test strategy should include the following characteristics −
Specify the testing area.
Describe the testing purpose.
Methodology for assessing activity
Testing timetable
Monitoring and reporting of bugs
Application Testing Instruments
There are several testing tools available for application testing. The instruments you choose will be determined by the sort of assessment you intend to do.
Various tools are suggested for each platform. Application testing tools assure application speed, accessibility, and operation across a wide range of devices.
Here are a few examples −
Selenium
IBM Rational Robot
RFT (Rational Functional Tester)
Load Runner ( HP Performance Tester)
Apache Jmeter
Checklist in Application Testing
Choosing the correct Application Testing technique is a sure way to uncover application flaws. As a result, it is critical that the QA team adhere to a set of established processes in order to find greater faults in much less time.
Some of the recommended practices for application testing include −
Specify functional requirements.
Examinations and inspections
Conditions for Formal Entry and Exit
Changes in functional tests
Testing on several platforms
Test execution that is automated
Application Testing Difficulties
During application testing, the tester may face a variety of obstacles.
Only when a customer calls issues are detected.
Incapability to predict the impacts of change
There is no insight into application and operational flaws.
It takes time.
Testing of Mobile Applications
Mobile application testing, like online application testing, is centered on the same test processes and methods. The difference might be in the testing tools utilized; some typical tools in use for mobile application testing are Sikuli, TestComplete, FoneMonkey, Robotium, and others.
There are three categories of mobile applications.
People access a web application via a network such as the internet or an intranet.
Native application- It is created for a particular platform and is installed on a computer.
The term "hybrid application" refers to an application that includes aspects from both the web and native platforms. Consider Facebook.
You can utilize simple CSS, HTML, JS, and so on for the majority of mobile platforms.
Test Case Examples for Mobile Application Testing
A comprehensive mobile testing application approach involves device and network architecture, targeted device identification, and a powerful mixture of manual and automated testing tools to handle both non-functional and functional testing.
Items to evaluate for a mobile application are −
Installation
OTA
Wi-Fi
Data Cable
Bluetooth
Uninstallation
Application logo
Splash
Low Memory
Visual Feedback
Exit Application
Start/Restart of Application
Test Case Examples for Mobile Application Testing
As the amount of mobile and devices grows, so does the evaluation of mobile apps. Evaluating a mobile application differs greatly from testing a desktop-based online application. The most prevalent difficulties encountered during mobile testing are as follows −
Complete test coverage
Fragmentation management (different O.S version, processor, memory)
There is no test plan.
Time Constraints
Physical gadgets are lacking.
Platform and operating system variety
Summary
Application Testing involves testing the complete application, which necessitates the use of a variety of approaches, resources, and methodologies. Application testing prior to go-live is important to the success of a software product.
