QTP Tests Using Keyword-Driven Testing

Keyword-driven testing advantages include the following:

1. In QTP, Keyword-driven testing enables you to design your tests at a business level rather than at the object level. For example, QTP may recognize a single option selection in your application as several steps: a click on a button object, a mouse operation on a list object, and then a keyboard operation on a list sub-item. You can create an appropriately-named function to represent all of these lower-level operations in a single, business-level keyword.

2. By incorporating technical operations, such as a synchronization statement that waits for client-server communications to finish, into higher level keywords, tests are easier to read and easier for less technical application testers to maintain when the application changes.

3. Keyword-driven testing naturally leads to a more efficient separation between resource maintenance and test maintenance. This enables the automation experts to focus on maintaining objects and functions while application testers focus on maintaining the test structure and design.


4. When you record tests, you may not notice that new objects are being added to the local object repository. This may result in many testers maintaining local object repositories with copies of the same objects. When using a keyword-driven methodology, you select the objects for your steps from the existing object repository. When you need a new object, you can add it to your local object repository temporarily, but you are also aware that you need to add it to the shared object repository for future use.

5. When you record a test, QTP enters the correct objects, methods, and argument values for you. Therefore, it is possible to create a test with little preparation or planning. Although this makes it easier to create tests quickly, such tests are harder to maintain when the application changes and often require re-recording large parts of the test.

6. When you use a keyword-driven methodology, you select from existing objects and operation keywords. Therefore, you must be familiar with both the object repositories and the function libraries that are available. You must also have a good idea of what you want your test to look like before you begin inserting steps. This usually results in well-planned and better-structured tests, which also results in easier long-term maintenance.

7. Automation experts can add objects and functions based on detailed product specifications even before a feature has been added to a product. Using keyword-driven testing, you can begin to develop tests for a new product or feature earlier in the development cycle.
