Modularity-driven testing

Modularity-driven testing is a term used in the testing of software.

Test Script Modularity Framework

The test script modularity framework requires the creation of small, independent scripts that represent modules, sections, and functions of the application-under-test. These small scripts are then used in a hierarchical fashion to construct larger tests, realizing a particular test case.

Of all the frameworks, this one should be the simplest to grasp and master. It is a well-known programming strategy to build an abstraction layer in front of a component to hide the component from the rest of the application. This insulates the application from modifications in the component and provides modularity in the application design. The test script modularity framework applies this principle of abstraction or encapsulation in order to improve the maintainability and scalability of automated test suites.

Let us discuss the modular framework architecture…

The core is the Master driver---This only consists of the calling business cases like—

login Create user Define attribute Logout The login module is again summation of 3-4 generic functions….like--

Open Application Set user id set Password Click on Ok/submit The data for this will come from Data table

The Module(business specific) might call an function which is not generic for other module but can have some functions which are generic in nature

say…

Write Customer Name in the text box is a generic function..where this is a type of setting a textbox with a specific value…this is generic across the application.

But if the test case is …

give 5% discount if the customer location is from Kolkata but 10% if he is from Hyderabad This type of function is still generic but specific to that module only.

This way the Modular specific function is build.all this is called in the business level and sequentially called in Script level.

so the structure is…

Driver Script-consists of high level business level statements…

Business Module-Consists of generic functions from generic function library or business specific functions from Business function library.

Common Functions:-Consists of all level of common functions.

Business Specific Functions: A library where all business specific functions resides.

Recovery Functions: A Function library where all types of recovery functions resides.

Data Table: Set of data for the testing.
