CSTE Test Cases 1. You are a tester for testing a large system. The system data model is very large with many attributes and there are a lot of interdependencies within the fields. What steps would you use to test the system and also what are the effects of the steps you have taken on the test plan? OR You are the test manager for about to the system testing. The development team says that due to change in requirements, they will be able to deliver the system to you for testing 5 working days after the due date. You cannot change the resources (Work hours, days, test tools). What steps will you take to be able to finish the testing in time? Solution 

Improve Supervision: More reviews of artifacts or program means Stage containment of the defects.



Creation of Base Line Data which is accurate and updated.



Strict Change Management: Correct versions are tested.



Phase wise / module wise approach for the testing.



More focus on Module and Integration testing.



Add more resources.



Work With Independent Test Team.



Automation for regression testing.



Rank the functionality as per risk and concentrate more on critical functionality testing



Effective

Communication

-

Reporting

of

critical

defects

(Using

defect

tracking/management system) and resolution plan discussion with development team 

Traceability matrix of changed requirement and Impact Analysis documents creation



Test cases updating as per Changed requirement



Exit criterion is achieved , release product

2. There is one application which runs on a single terminal. There is another application that works on multiple terminals. What are the tests techniques you will use on the second application that you would not do on the first application? Solution 

Concurrency Test



Update and Rollback



3. Explain give examples of the following black box techniques.

CSTE Test Cases a. Boundary Value testing b. Equivalence testing c. Error Guessing Solution Boundary Value Analysis: If Valid Input is 100 Boundary + 1 = 101 Boundary Value = 100 Boundary – 1= 99 Equivalence Partitioning: If Valid Input is in the Range of 10 and 15 Invalid Below the Partition = 8 Valid In the Partition = 12 Outside of the Partition = 18 Error Guessing: Its testers experience to test the functionality creating such a data which may cause failure. Eg – Feb 29, 2001 4. What are the product standards for? a. Test Plan b. Test Script Solution: Test Plan: 

Scope



Objective



Assumptions





Test Environment



Tools



Schedule



Test Design



Test data Management



Communication

Test Script: 

Sequence



Source : Data Entry Operator



Script Event : Enter Invalid Input



Evaluation Criterion : Error Message Should be Displayed



Comments : Help regarding valid Input



State that it does not support to other OS and browsers, if risk is involved.



Commercial Risk : Ensure competitive look and feel , Easy Navigation



Business Risk : Ensure Transaction Correctness ,Security (data), transactions, roll back procedure etc



Proper Authorization in Place



Response time (performance)
