CTAL-TTA Exam Dumps : Certified Tester Advanced Level Technical Test Analyst

The control flow graph provided illustrates the decision points for an airline's upgrade and boarding process. Decision coverage is a measure of the percentage of decision points executed during testing:

Test 1 covers the decision points: Gold card? (Yes) and Business full? (No).

Test 2 covers: Gold card? (No) and Economy full? (No).

Test 3 covers the decision that leads to being bumped from the flight, which is Economy full? (Yes) and Business full? (Yes).

From the given tests, the decision points for Gold card? (No) and Business full? (No) are not tested, leaving us with 4 out of 6 decision points covered, which is approximately 67% decision coverage.

Analysis:

To determine the correct keyword-driven input table for testing the enhancement to the social media application, we need to ensure the table adequately covers the following scenarios:

Adding existing members to a group.

Attempting to add non-existing members to a group and handling the error.

Removing members from a group.

Deleting groups only if no members are attached.

A. (Image A) - Assuming Image A correctly represents these scenarios.

Adding Members: The table should include steps to add both valid (existing) and invalid (non-existing) members to a group, ensuring the application correctly handles both scenarios.

Removing Members: The table should include steps to remove members from a group.

Deleting Groups: The table should include a scenario where a group with no members is deleted successfully.

General knowledge on keyword-driven testing.

The statement that is true about test approaches is that in a Model-based test approach, tests can be created automatically. This is confirmed by the understanding that model-based testing involves generating test cases directly from a model that describes the system functions, behavior, or both, which supports automatic test creation​​.
