Testing strategy refers to a set of guidelines that aid the test design and regulates the process of testing and how it should be done. The chief components of the testing strategy are objectives and scope, documentation formats, team reporting structure, test processes, client communication strategy and so on. It narrates the general approach put forward in the process of testing. The steps of the testing strategy aids to inform the project managers, developers, and testers about the main issues faced during the testing process. The testing strategy is the chief component of software testing efficiency. The programmer should indent to provide the most efficient and effective method of testing the software while developing the testing strategy. The selection of the testing strategy contributes to be one of the most important factors to assess the success of the test plans and its estimates.
The following are a few types of testing strategies:
Analytic Testing Strategy
This strategy depends on the analysis of the factors that strongly affect the testing environment. The strategy uses formal and informal methods to access and prioritize risks that come up while running the software test. It requires an entire overview of design, requirements, and implementation of objects to determine the test motive. Additionally, the analytic testing strategy collects complete information regarding the software, the data needed for testing the software and the targets to be achieved.
Model Based Testing Strategy
This form of testing strategy tests the way the software functions according to the real world scenario, such as the functioning of the particular software in an organization, etc. The strategy identifies the domain of the data and chooses suitable test cases depending on the probability of errors in that domain. The major advantage of this strategy is that the testing will be consistent with the real world usage.
Methodical Testing Strategy
This type of testing uses the standard set of test conditions. The conditions chiefly include a quality standard, a checklist, logical test conditions and so on. The strategy includes consistent testing of defined attributes. The major demerit of this type of strategy is that it can be insufficient or can contain outdated test basis. This is mainly used to verify the reliability, usability, functionality, and performance of the software.
Process-oriented Testing Strategy
This testing strategy tests the software from the existing standards like the IEEE standard. With the help of automated testing tools, this approach checks the functionality of the software. The major benefit of this strategy is that it utilizes the skills and experience of standard creators.
Dynamic Testing Strategy
Dynamic testing strategy tests the software after retrieving the collective decision of the testing team. It also provides information such as the test cases used for testing the errors of the software and so on along with the testing.
Philosophical Testing Strategy
This strategy tests by assuming that any component of the software can stop functioning any time. This approach requires help from software developers, system analyst and users to perform the testing of the software.

When a legacy application is modernized, transaction flow may be changed to adjust to the standards and capabilities of the new platform. If tests are automated using a traditional testing tool, those user interface changes would require a significant amount of test maintenance to get tests running on the new platform. AscentialTest provides a short-cut by allowing users to develop...
