SDLC

Question 1

Describe the idea creation stage of the SDLC? When does it happen?

Answer 1

1st stage

investigate the market and form hypotheses about the product

Question 2

What is the requirement formation stage of the SDLC?

Answer 2

specific requirements for the application are defined

what should be implemented?
what are the limitations of the system under development?

Question 3

Describe the design stage of the SDLC? When does it happen?

Answer 3

it happens after the requirements have been formulated

• the architecture of the software is formulated through documentation, tech specs or layouts

Question 4

In which stage of SDLC is the application created?

Answer 4

Development and testing

Question 5

What happens during the development and testing stage of the SDLC?

Answer 5

• code is written
• testing is carried out
• corrections are made according to feedback

Question 6

What are the final three stages of the SDLC?

Answer 6

Release: software becomes available to end users
Maintenance: maintaining the application’s functionality and fixing bugs on an ongoing basis
Discontinuation: the app becomes outdated and is no longer supported

Question 7

What does the QA Engineer do during the idea creation stage?

Answer 7

• understand the product
• analyze the product logic
• find issues with the logic
• start making a list of user scenarios to test

Question 8

What does the QA Engineer do during the requirement formation stage?

Answer 8

• analyze the requirements for completeness, consistency and testability
• suggest improvements
• start compiling test documentation

Question 9

What does the QA Engineer do during the design stage?

Answer 9

• make sure the project implementation corresponds to the original requirements
• work on test docs
• design test cases for automation
• start estimating the amount of time required for testing

Question 10

What does the QA Engineer do during the development and testing stage?

Answer 10

• finish the test docs
• test the product
• continue designing automated tests
• make the final decision on whether functionality is ready and officially sign off on the release

Question 11

What does the QA Engineer do during the release stage?

Answer 11

• conduct regression, smoke and sanity testing
• check that the product functions according to requirements in a production env
• collect feedback from end users
• retest bugs found in the production environment after devs fix them

Question 12

What does the QA Engineer do during the maintenance stage?

Answer 12

• process feedback from users by replicating, verifying and retesting after devs fix bugs
• test upgrades and new features

Question 13

What does the QA Engineer do during the discontinuation stage?

Answer 13

check that only expected functionality was removed and that the rest of the app works as expected

Question 14

In which type of software development is each stage done step by step and the next phase can’t start before the previous one?

Answer 14

sequential

Question 15

What are the 3 types of sequential software development

Answer 15

• waterfall
• v-model
• spiral

Question 16

Describe the waterfall model of sequential development.

Answer 16

• project activities are broken down into linear sequential phases
• each phase depends on the deliverables from the previous one

Question 17

In what scenarios is it useful to use the waterfall model?

Answer 17

• product requirements are set and unlikely to change in the near future
• the result of the project is known in advance
• when product development can be broken down into sequential stages

Question 18

What are the drawbacks of the waterfall model?

Answer 18

• less flexible
• can increase the financial cost of the project dramatically

Question 19

Describe the core values of the agile principles.

Answer 19

• respond to changes more than following a plan
• talk to the team and customers daily
• deliver working software as frequently as possible

Question 20

What is the scrum methodology?

Answer 20

• work broken down into sprints
• tangible goal for every sprint to deliver some part of the functionality
• team discusses and agrees on which items they intend to complete during the next sprint, as well as possible workflow improvements that can be made

Question 21

What are the 4 stages of the scrum workflow?

Answer 21

Sprint planning
Development and testing
Demonstration: my bug demos
Retrospective: reflect on the previous sprint

Question 22

What is the role of the QA Engineer during the sprint planning stage?

Answer 22

assess the amount of work and the difficulty of that work from their POV

Question 23

What is the role of the QA Engineer during the development stage?

Answer 23

• help design product requirements
• compile test docs
• test any new functionality for the first release

Question 24

What is the role of the QA Engineer during the demo meeting?

Answer 24

like the bug demos at Carehive! presenting the work done

Question 25

What is the role of the QA Engineer during retrospectives?

Answer 25

think about how to make the testing process more efficient

Question 26

Explain what each of the numbers mean in software versioning IDs - Version 4.3.2

Answer 26

4 - major
3 - minor
2 - revision

Question 27

What type of changes happened in a version release that went from 3.3.2 to 4.3.2?

Answer 27

global changes in the app (major)

Question 28

What type of changes happened in a version release that went from 4.3.2 to 4.4.2?

Answer 28

important improvements made to the app (minor)

Question 29

What type of changes happened in a version release that went from 4.3.2 to 4.3.3?

Answer 29

minor modifications (revision)

Question 30

Explain what a build is in software development.

Answer 30

taking all the programming pieces (like Lego blocks) and instructions and turning them into a working program

3 developers are building different parts of a lego castle

assembling all of the legos from each developer into the final castle to play with is a build (release build)

Question 31

What is an important difference to note between build numbers and version numbers?

Answer 31

build numbers are used internally while version numbers are what the users actually see
