Who would be consulted during phase “Self Unit Testing”?

  1. TCS Program Manager

  2. Functional Track Lead

  3. Functional Consultant

  4. Technical Consultant
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

During the developer's Self Unit Testing phase, the developer (Technical Consultant) consults the Functional Consultant to clarify requirements and verify that the built logic matches the functional specifications. The TCS Program Manager and Functional Track Lead occupy higher oversight roles and are not typically consulted for unit-level testing details.

When software reliability measures are used to determine when to stop testing, the best types of test cases to use are those that

  1. Exercise system functions in proportion to the frequency they will be used in the released product

  2. Push the system beyond its designed operation limits and are likely to make the system fail

  3. Exercise unusual and obscure scenarios that may not have been considered in design

  4. Exercise the most complicated and the most error-prone portions of the system

Which of the following are disadvantages of capturing tests by recording the actions of a manual tester? i The script may be unstable when unexpected events occur. ii Data for a number of similar tests is automatically stored separately from the script. iii Expected results must be added to the captured script. iv The captured script documents the exact inputs entered by the tester. v When replaying a captured test, the tester may need to debug the script if it doesn’t play correctly.

  1. i, iii, iv, v.

  2. ii, iv and v.

  3. i, ii and iv.

  4. i and v.

Which three statements are true about debugging a process using the TIBCO Designer Tester Utility? (Choose three)

  1. Step Into and Step Out of a subprocess can be used

  2. The process definition can be changed while debugging

  3. The current process instance can be paused during testing

  4. Input data can be supplied via an xml file to the process starter
Reveal answer Fill a bubble to check yourself
A,C,D Correct answer
Explanation

The TIBCO Designer Tester Utility allows developers to step into and out of subprocesses, pause current process instances during execution, and feed test data to process starters via XML files. However, process definitions cannot be modified dynamically during an active debugging session.

The testing technique that requires devising test cases to demonstrate that each program function is operational is called

  1. Black-box testing

  2. Glass-box testing

  3. Grey-box testing

  4. White-box testing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Black-box testing focuses on validating functional requirements, ensuring that each program function is fully operational and produces the expected outputs for given inputs. Glass-box and white-box testing focus on internal program logic and code paths rather than verifying operational requirements from a functional perspective.

Multiple choice technology testing

The testing technique that requires devising test cases to exercise the internal logic of a software module is called

  1. Behavioral testing

  2. Black-box testing

  3. Grey-box testing

  4. White-box testing
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

White-box testing (also called glass-box or structural testing) examines the internal structure and implementation details of software. It requires knowledge of the code to design test cases that cover internal paths and logic. This contrasts with black-box testing which only considers inputs and outputs.

Multiple choice technology testing

Black-box testing attempts to find errors in which of the following categories

  1. Incorrect or missing functions

  2. Interface errors

  3. Performance errors

  4. All of the above

  5. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Black-box testing validates software functionality by examining inputs and outputs without accessing internal code. It checks for incorrect or missing functions, interface errors, and performance issues by testing against specifications. This approach evaluates the system from an external user perspective, simulating real-world usage scenarios.

Multiple choice technology testing

What types of errors are missed by black-box testing and can be uncovered by white-box testing ?

  1. Behavioral errors

  2. Logic errors

  3. Performance errors

  4. Typographical errors

  5. Both b and d
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

White-box testing examines internal program structures. Logic errors (like incorrect paths) and typographical errors (like variable misspellings that still compile but cause wrong execution flows) can be missed by black-box testing, which only verifies external inputs/outputs. Both behavioral and performance errors are typically checked in black-box testing.

Condition testing is a control structure testing technique where the criteria used to design test cases is that they

  1. Rely on basis path testing

  2. Exercise the logical conditions in a program module

  3. Select test paths based on the locations and uses of variables

  4. Focus on testing the validity of loop constructs
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Condition testing is a white-box technique that focuses on exercising logical conditions within program modules. It tests various combinations of condition outcomes to ensure all logical paths are validated. The approach specifically targets decision points and boolean expressions, distinguishing it from other control structure testing techniques.

Multiple choice technology testing

Data flow testing is a control structure testing technique where the criteria used to design test cases is that they

  1. Rely on basis path testing

  2. Exercise the logical conditions in a program module

  3. Select test paths based on the locations and uses of variables

  4. Focus on testing the validity of loop constructs
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Data flow testing selects test paths based on how variables are defined (assigned) and used (referenced) throughout the program. It tracks the flow of data between variable definitions and their uses to ensure coverage of data relationships. Option A describes basis path testing, option B describes condition testing, and option D describes loop testing, which are different white-box testing techniques.

Multiple choice technology testing

Loop testing is a control structure testing technique where the criteria used to design test cases is that they

  1. Rely basis path testing

  2. Exercise the logical conditions in a program module

  3. Select test paths based on the locations and uses of variables

  4. Focus on testing the validity of loop constructs
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Loop testing specifically focuses on testing loop constructs to ensure they function correctly for different scenarios. It tests loop boundaries (zero iterations, one iteration, maximum iterations, n+1 iterations) and loop termination conditions. Options A, B, and C describe different testing techniques: basis path testing, condition testing, and data flow testing respectively, which have different focuses than loop constructs.

When do you use Spring in testing?

  1. Stress Testing

  2. Regression Testing

  3. Integration Testing

  4. None
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Spring is primarily used in integration testing to test how different components work together. It allows you to load the application context, wire beans together, and test interactions between components in a near-production environment. Stress testing focuses on system limits, and regression testing checks for bugs in existing functionality.

Multiple choice technology testing

Testing which is simulated or actual operational testing by potential users/customers or an independent test team at the developers' site is called

  1. Alpha Testing

  2. Beta Testing

  3. White Box Testing

  4. Black Box Testing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Alpha Testing occurs at the developer's site by internal staff or independent testers before release. Beta Testing happens at the customer's site with actual users in their environment. The question specifies 'at the developers' site,' which is the defining characteristic of Alpha Testing.
