Understanding Structure-Based Testing: Key Techniques Explained

Question 1 (1 point) ' Saved g usten] > ] What is a key characteristic of structure-based testing techniques? (® They are used both to measure coverage and to design tests to increase ~ coverage. O They are based on the skills and experience of the tester. O They use a formal or informal model of the software or component. O They are mainly used to assess the structure of a specification. Question 2 (1 point) Saved [ @usen] » ] ‘Why are error guessing and exploratory testing good to do? O They will ensure that all of the code or system is tested. O They can be used most effectively when there are good specifications. O They don't require any training to be as effective as formal techniques. @ They can find defects missed by specification-based and structure-based ~ techniques.

Question 3 (1 point) Saved ] ‘Why are both specification-based and structure-based testing techniques useful? C) Both find the same type of defect. Q Because specifications tend to be unstructured. C) Using more techniques is always better. @) They find different types of defect. Question 4 (1 point) ~ Saved [5] O Listen | B What does load testing of Web applications measure? (:) Response time: how long the user waits after issuing a request until seeing the response O Stress testing for resilience to network dropouts or server failures O Scalability or ability to keep up with demand as the number concurrent users grows @ Throughput, typically measured as number of requests processed per second on the server O Usability of a browser-based user interface

Question 5 (1 point) Saved [0 uisten [ » What is the primary difference between the test plan, the test design specification and the test procedure specification? o The test plan describes one or more levels of testing, the test design ~ specification identifies the associated high-level test cases and a test procedure specification describes the actions for executing a test. ~ The test plan is finished in the first third of the project, the test design ~ specification is finished in the middle third of the project and the test procedure specification is finished in the last third of the project. Q The test plan is the least thorough, the test procedure specification is the most -~ thorough and the test design specification is midway between the two. C The test plan is for managers, the test design specification is for programmers and the test procedure specification is for testers who are automating tests.
