What is Quality? - 🧠ANSWER ✔✔Customer satisfaction? Subjective term.
What is Software Quality? - 🧠ANSWER ✔✔Measurement of how close is
actual software product to the expected (intended) product; Customer
satisfaction (to who?)
What is Software Quality Assurance? - 🧠ANSWER ✔✔Software QA is the
process of monitoring and improving all activities associated with software
development, from requirements gathering, design and reviews to coding,
testing and implementation.
What is the difference between Software Testing and Software QA? -
🧠ANSWER ✔✔Testing is mainly an 'error detection' process Software QA
is 'preventative'. It aims to ensure quality in the methods & processes.
,("Quality Assurance" measures the quality of processes used to create a
quality product)
What is Software Testing? - 🧠ANSWER ✔✔Software Testing is the process
of analyzing the software in order to detect the differences between existing
and required conditions and to evaluate the features of the software. It
involves the entire software development process:
- monitoring and improving the process
- making sure that any agreed-upon standards and procedures are followed
- ensuring that problems are found and dealt with, at the earliest possible
stage· The purpose of testing is verification, validation and error detection
(in order to find and fix the problems)
- Verification is checking for conformance and consistency by evaluating
the results against pre-specified requirements. (Verification: Are we
building the system right?)
- Validation is the process of checking that what has been specified is what
the user actually wanted. (Validation: Are we building the right system?)
- Error Detection: finding if things happen when they shouldn't or things
don't happen when they should.
, Since it isn't possible to find/fix all the bugs in a software product before it
goes to the customers why should we test? - 🧠ANSWER ✔✔To establish
and to enforce business systems of the QA Organization (Test planning,
bug tracking, bug reporting, test automation, release certification, and
others)
What is black box testing? - 🧠ANSWER ✔✔Testing without any knowledge
of the inner workings of the item being tested. E.g., when black box testing
is used to software engineering, the tester would only know the "valid"
inputs and what the desired outputs should be, but not how the program in
reality comes at those outputs. It's because of this that black box testing
can be considered validation with reference to the specifications, no
additional knowledge of the application under test is necessary. Because
this reason, the tester and the programmer can be independent of one
another, avoiding coder bias towards his own work. This process of test
design is applicable to all levels of software testing: unit, integration,
functional testing, system and acceptance. The higher the level, and
therefore the greater and a lot complex the box, the more one is forced to
use black box testing to simplify. Although this process can uncover
unimplemented parts of the specification, one can't be certain that all
existent paths are validated.
