Software Testing and Quality Control Questions

Multiple choice technology testing

If this is the first time an automated testing approach has been used for a project, it is important to generate a metric that calculates the

  1. Cost of automation

  2. Performance of automation

  3. Value of automation

  4. Quality of automation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

When introducing automation, demonstrating its value (such as ROI and time saved) is critical to justify the initial high investment. While cost, quality, and performance are important metrics, proving value is the primary driver for adoption.

Multiple choice technology testing

Automation Index can be defined as the

  1. Effort needed to automate a set of given test cases

  2. Cost needed to automate a set of given test cases

  3. Percentage of a set of given test cases that is automatable

  4. Investment done to automate a set of given test cases
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Automation Index measures what portion of your test suite can be automated. Option C correctly identifies it as a percentage of automatable test cases. The other options focus on cost, effort, or investment rather than the core metric of automatability.

Multiple choice technology testing

The number of test cases automated divided by the total number of test cases automatable gives

  1. Percentage automatable

  2. Automation progress

  3. Automation Index

  4. Automation coverage index
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Automation Progress tracks completion of your automation effort by comparing automated cases against automatable ones. Unlike Automation Index (which measures potential), this measures actual progress toward that potential.

Multiple choice technology testing

Defects holding maximum test cases reports

  1. Defects with severity 1 and 2

  2. Defects that are keeping maximum number of test cases in wait

  3. Defects that are linked with same requirement

  4. Defects with a high priority
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This report identifies defects that block the execution of the largest number of test cases, keeping them in a waiting state. High severity or priority bugs do not necessarily block tests, and requirement linking does not measure blocking status.

Multiple choice technology testing

The following metric belongs to the Quality category of reporting

  1. Error discovery rate

  2. Problem reports by priority

  3. Defect ageing

  4. Defect fix retest
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Problem reports by priority directly reflects quality by showing the distribution of defects by severity. This quality-focused metric differs from process metrics like ageing or retest, which measure timing and workflow efficiency.

Multiple choice technology architecture

Which method causes the system to end the current activity and the calling activity,continue with the next activity on the requestor's activity list?

  1. (a) Activity-End

  2. (b) End-Activity

  3. (c) Exit-Activity

  4. (d) Activity-Exit
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Activity-End terminates both the current activity and the calling activity, then continues with the next activity on the requestor's list. End-Activity, Exit-Activity, and Activity-Exit are not valid PRPC method names.

________Check box in Obj-Save method and_______Check box in Obj-Delete method facilitate immediate write into database, without actually waiting for Commit method

  1. a. Immediate, Write-Now

  2. b. Write-Now, Immediate

  3. c. Save-Now, Immediate

  4. d. Immediate, Save-Now
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Obj-Save has a Write-Now checkbox that writes immediately to the database, while Obj-Delete has an Immediate checkbox for the same purpose. Both bypass the normal Commit method requirement when these checkboxes are selected.

Multiple choice technology architecture

Which method causes the system to end the current activity and the calling activity,continue with the next activity on the requestor's activity list?

  1. (a) Activity-End

  2. (b) End-Activity

  3. (c) Exit-Activity

  4. (d) Activity-Exit
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Activity-End is the correct Pega method that terminates the current activity and returns control to the calling activity, which then continues with the next activity on the requestor's list. This is essential for controlling flow in Pega processes. The naming convention places the object (Activity) before the action (End).

Multiple choice technology architecture

________Check box in Obj-Save method and_______Check box in Obj-Delete method facilitate immediate write into database, without actually waiting for Commit method

  1. a. Immediate, Write-Now

  2. b. Write-Now, Immediate

  3. c. Save-Now, Immediate

  4. d. Immediate, Save-Now
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In Pega, Obj-Save has a Write-Now checkbox that causes immediate database write, while Obj-Delete has an Immediate checkbox for the same purpose. Both bypass the standard Commit method queue and perform the database operation instantly. Remembering which method uses which checkbox name is key.

Multiple choice technology testing

If the impact of a defect is severe, but interim solution is available and the defect is not hindering the test process, then such a defect will fall under which category?

  1. Critical

  2. Major

  3. Minor

  4. Severe
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A Major defect is one with significant impact that still allows testing to continue, especially when a workaround exists. Critical defects block testing entirely, while Minor defects have negligible impact. The presence of an interim solution confirms this is Major rather than Critical.
