Windows is an exciting platform for app developers. It is creating new opportunities for creating wider customer reach and international presence. Windows app testing is comparatively simpler as one has full control over Windows applications. The only complexity lies by testing through intranet in which clients and servers are known.
There are certain things to be remembered in windows application testing. Those things are understanding the important functionality of the windows application, identifying the high risk module of the application, identifying the most important aspects of application, identifying the high risk functionality as well as most visible functionality of the application, identifying problem areas where and best publicity of the applications are obtained, collecting views of developers regarding the high risk aspects of the application and identifying functionalities of the largest financial impact of the application.

Following are the various types of testing carried out during windows app testing:
The application is either tested fully for upgrades install or uninstall procedures on different platforms. This is usually performed under different operating systems which is operating under different hardware and software environment. The following is a brief checklist for install or uninstall testing:
a. Checking whether there is a need for the support of different platforms and configurations
b. Is the installer capable of calculating needed disk space?
c. Are there any discrepancies in the amount of space as per the claims of installer for various types of installation?
d. If the installation is stopped in the midway, how much disk space will be utilized by the installer?
e. If there are any errors at the time of installation, does installation recover?
f. Can the installer repair corrupt installation?
2. Compatibility Testing
This type of testing looks at the software performance in a particular configuration which includes software, hardware, operating system, network environment and cross platform functionality.
3. Smoke testing
This type of testing is generalized functionality testing without getting into the core functionality in depth.
4. Sanity testing
This type of testing is to check whether the application is to be considered for testing effort. The system is considered unsuitable for any further testing, if the application crashes during initial use. And hence build or application is assigned for the purpose of build fix or application fix.
5. GUI or Interface testing
In the case of software or application, it is the interface that must be tested properly. Here is a small checklist for interface testing:
a. Checking whether the entire spell is correct on the interface
b. To ensure that the entire tab index is proper
c. Checking whether there is proper alignment of the label and other fields
d. Checking whether there is any sign for mandatory fields
e. Is there any proper tool tip of the elements?
f. Assuring that the application’s CSS and interface design are the same
6. Unit testing
This type of testing deals with testing program parameters as an independent functional unit.
7. Functional testing
Functionality of the application must be proper. This type of testing focuses on the output generation which suits the requirement. It can be considered as an improvisation of black box testing, which cater to the functional requirements of the application.
8. Integration testing
This type of testing is used to check integrated modules which verify combined functionality after integration. Modules may include individual applications, code modules, client and server application on a network, etc. this type of testing is relevant to client or server and distributed systems.
9. Incremental integration testing
This type of testing adopts the bottom up approach for testing. And it is mandatory on enhancements and patch applications. It can either be done by programmers or testers.
10. System testing
In this type of testing, the entire functionality of the system is tested as per the system requirement documents. It is also a type of black box testing, which is based on an overall requirement specification that covers integrated parts of the system.
11. Acceptance testing
This type of testing is done to verify whether the system meets customer requirements. It is the end user who determines whether the functionality meets their requirements.
12. Regression testing
This type of testing applies to the application in totality for the modification of functionality. Automation tools provide the needed support to cover all aspects of regression.
13. Usability testing
This part of testing focuses on user friendliness. It is tested on the basis of help documentation availability and ease of use. In this testing, system navigation is checked in.
14. Alpha testing
An In house virtual user environment is created similar to the implementation environment in this type of testing. It is normally done at the end of development cycle.
15. Beta testing
This type of testing is performed by end users or users outside the project. It is a kind of final testing before releasing the application for commercial purpose.
16. Comparison testing
Through this type of testing, product strength in terms of functionality is compared with competitor products. And in the case of version or release, the existing one is compared to change requested.
17. Performance testing
Depending on the application to be tested, it can be called as load or stress testing. This test is done to check whether a system meets performance requirements.
18. Stress testing
This testing is performed under heavy load subjecting the application to huge information, performing complex database queries, requesting heavy retrieval of information or rapid and continuous input.
19. Load testing
This type of performance testing is used to check the system’s behavior under load. The application is subjected to heavy loads in order to determine the point of degradation, the system’s response time and failure to perform the intended functionality.
20. Security testing
This type of testing is to check whether the system can be penetrated by any hacking methods. It concentrates on the system and the database security against external attacks.
