• Optimizing object identification strategies.
• Using descriptive programming for greater flexibility.

84. How do you handle the maintenance of QTP scripts when the application under test changes frequently?

Ans:

They maintain QTP scripts when the application under test changes frequently, which requires a modular and reusable scripting approach. This involves breaking down test scripts into smaller, reusable components and functions, making updates more efficient. Shared object repositories and descriptive programming help manage dynamic changes in object properties. Regularly reviewing and updating object properties and implementing robust version control practices ensure scripts remain adaptable and maintainable.

85. How can a slow-running QTP script be optimized?

Ans:

To optimize a slow-running QTP script, identify and address performance bottlenecks such as inefficient loops, excessive waits, and redundant actions. In one instance, replaced static waits with dynamic waits that only wait until required conditions are met, streamlined object identification by refining the properties used for recognition, and broke down large scripts into smaller, more manageable components. These steps improved maintainability and execution speed.

86. How is the reusability of QTP scripts ensured across different projects?

Ans:

• Ensuring the reusability of QTP scripts across different projects involves creating modular, parameterized, and well-documented scripts. Using reusable functions and actions across different test scenarios promotes consistency and reduces redundancy.
