Life Cycle of Application Testing

Like our traditional waterfall model, application testing involves the following phases of the testing lifecycle. These phases are as follows.

• Test Design: It involves designing the test plans based on the application requirements.
• Test Development: It involves the development of manual test cases as well as automated test scripts.
• Test Execution: It involves execution of functional tests for validation of application requirements.
• Application Tuning: In involves execution of load tests and tuning application performance.

Application Testing Category

Application testing can be categorized into the following three segments.

• Web Application Testing: Web application testing involves the testing of dynamic or static websites. There are many types of testing which can be done as a part of web application testing depending on the testing need.
• Desktop Application Testing: Desktop application testing involves testing of desktop applications such as MS Office, Skype, etc. There are many types of testing which can be done as a part of desktop application testing depending on the testing need.
• Mobile Application Testing: Mobile Application testing involves testing of mobile applications such as Gmail mobile app, Skype mobile app, banking mobile app, etc. There are many types of testing which can be done as a part of mobile application testing depending on the testing need.

Application Testing Methodologies

The following are the different types of testing methodologies which can be used to ensure the required level of testing depending on the application type.

• Functional Testing or Black box testing: In functional testing methodology for any type of software application, the output result is matched with the expected result for the given set of inputs. In this type of testing since the tester has no knowledge of the code, therefore, it is known as Black Box testing.
• White box testing or unit testing: In white box testing, the tester has the knowledge of the code. Such kind of testing is often done by the developers immediately after they complete coding for any application module.
• Grey box testing: The term grey box testing refers to the mix kind of testing between black box testing and white box testing. Here, the tester can adopt the mixed strategies involving both black boxes as well as white box testing strategies.
