CTFL-Foundation Exam Dumps : ISTQB Certified Tester Foundation Level

Incremental testing approaches involve testing components of the software in increments or steps, allowing for integration and testing of parts of the system progressively. According to the ISTQB CTFL Syllabus, version 4.0, the common types of incremental testing approaches include:

Top-down: Testing starts from the top of the module hierarchy and progresses downwards.

Bottom-up: Testing begins with the lower-level modules and progresses upwards.

Functional incrementation: Adding and testing one function at a time.

Big-bang testing, however, is not an incremental approach. In big-bang testing, all components or modules are integrated simultaneously, and the system is tested as a whole. This approach does not allow for incremental testing and integration and is therefore not considered a type of incremental testing approach​​.

Designing the test environment setup and identifying any required infrastructure and tools are part of the "Test Analysis and Design" phase. According to the ISTQB Certified Tester Foundation Level Syllabus v4.0, the activities in this phase include creating high-level and detailed test designs, test cases, and test data, and specifying the necessary test environment, tools, and infrastructure. These preparations are essential for the subsequent phases of test execution and monitoring.

To meet the test plan requirements and logical dependencies, the test schedule should start with re-tests (those that have previously failed), followed by the highest priority tests. Additionally, tests should be scheduled to create necessary test data for subsequent tests. In this case, teste(log in as admin user and create a standard user) must be done first as it is necessary to perform all other actions. Following this, testa(log in as standard user and create customer account) creates the standard user needed for subsequent actions. Then, the highest priority testd(order twoitems or more), which has failed before, should be executed next, followed by testc(create invoice for order), and finally testb(order one item)​​.
