Component testing
White box testing- unit test- done by the developer at the ocde level
Test Basis (what creates the component) and Test Objects (what we test)
Test Basis-
Component requirement
Code
Detailed Design
Test Objects –
Component
Programs
Data conversion/migration
Database Modules
Integration Tetsing
interaction between modules
Component Integration Testing – data shares/interacted of components with in module – Site selection- city selection- in address page.
System Integration Testing – a small unit of system- a small transaction in a big application SIT- Several SITs put together for System testing- in few cased SIT can be converted after System testing as well,
EX: Embedded Systems – S/w -H/w or Sw/SW etc..
3 Approaches
TDA – Top Down Appraoch
BUA- Bittom Up Approach
BBA – Big Bang Approach
Test Basis: References for deriving the test cases.

Sytem Testing(K2)
E2E testing of an applciation – to handle the e2e as everyhting works as per business/system requitrments of applciation. we hangle lots of roisk- as once the app is built we can cater teh critical things as part of hte execution.
Test Basis

ONce afte te syateme tetsig is done- non functional testing can be started
ACCEPTANCE TETSING
once all teh testinare done- it can be declared tha tclient can come anc collec the app
ISTQB- client comes to dev primises an conducts te acceptance testing int he applciation is called as acceptance testing
Typical
User Acceptance
Operational
Regulatory
Contractual
Business
Client genrally accepts the app- they specify what criteria is met and not met- so typical form of accptanc eis amade
Levels of Tetsing
Alpa Tetsing – tested by the client
Beta testing – to provide the peice ofd app to certain group and collect valuable feedback-must be conducted
(AB Testing)- cetain places- we cannot ask te endusers ex: fantasy park, amusemnt park, aerospace, safety critical- aerospace – so we ask professionals to behave like end users and collect feedback
