Becausee testinge helpse toe guaranteee thate thee softwaree ise functional,e dependable,e ande ofe goode
quality,e ite ise ae cruciale stepe ine thee softwaree developmente process.e Withoute adequatee testing,e
softwaree maye havee bugs,e mistakes,e ande othere problemse thate affecte bothe itse usabilitye ande
performance.e Toe makee suree thate everye componente ofe thee softwaree ise adequatelye tested,e
multiplee degreese ofe testinge aree used.e Unite testing,e integratione testing,e systeme testing,e ande
acceptancee testinge aree somee ofe thesee levels.
Unite testinge focusese one testinge individuale unitse ore componentse ofe thee softwaree toe ensuree thate
theye aree functioninge correctly.e Integratione testinge involvese testinge thee integratione ofe
differente unitse ore componentse toe ensuree thate theye worke togethere ase intended.e Systeme testinge
involvese testinge thee softwaree ase ae wholee toe ensuree thate ite meetse thee requirementse ande
performse ase expectede ine ae real-worlde environment.e Acceptancee testinge involvese testinge thee
softwaree toe ensuree thate ite meetse thee needse ande expectationse ofe thee end-users.
Differente levelse ofe testinge aree requirede rathere thane simplye onee sincee eache levele hase ae distincte
focuse ande goal.e Fore instance,e unite testinge concentratese one thee software'se distincte parts,e
wherease integratione testinge concentratese one howe thosee partse interact.e Ite woulde bee
challenginge toe guaranteee thate thee softwaree ise completelye functionale ande meetse thee needse ande
expectationse ofe thee ende userse withoute thesee manye testinge levels.
Ite ise importante toe havee multiplee phasese ofe softwaree testinge becausee ite helpse toe reducee thee
chancese ofe errors.e Ite alsoe helpse toe makee suree thate thee customere needse aree fulfilled.e Everye
stagee ofe softwaree testinge helpse thee developerse toe assesse thee characteristicse ofe thee softwaree
ande evaluatee ife thee softwaree fulfillse thee demandse ofe thee cliente ore customer.e Withe thee helpe ofe
variouse testinge ite ise possiblee toe identifye thee errorse ande shortcomingse ine thee applicationse priore
toe itse deploymente ande largescalee production.e Theree aree 5e phasese ofe softwaree testing,e knowne
ase statice testing,e unite testing,e integratione testing,e systeme testinge ande acceptancee testing.
Thee 3e maine activitiese fore softwaree testinge aree planninge ande control,e analysise ande designe ande
implementatione ande execution.e Ine thee planninge ande controle stagee thee requirementse ande
parameterse ofe thee softwaree aree decided.e Thee parameterse fore completione ofe thee projecte aree
alsoe decidede ine thise stage.e Thee nexte activitye ise thee analysise ande designe wheree thee softwaree ise
analyzede ande thee blueprinte fore thee differente designe techniquese aree decided.e Thee finale activitye
ise thee implementatione ofe thee designe accordinge toe thee plane ande makinge suree thate thee cliente
requirementse aree fulfilled.e Thene thee projecte ise deployede accordinge thee demandse ofe thee
customer.e
Testinge ande qualitye assurancee ise involvede throughoute thee softwaree engineeringe processe
becausee ite letse thee developere studye piecese ofe thee codee toe seee ife ite meetse thee needede
requirementse ande ite properlye workse undere alle conditions.e Normallye differente partse ofe thee
programe ise madee bye differente developerse ande ite ise pute togethere throughoute thee softwaree
process.e Ite ise importante toe teste throughoute thee developmente stepse toe makee suree ase maye ase thee
bugse aree removed,e thee softwaree ise doinge whate ite shoulde bee doinge ande toe makee suree thee
differente piecese ofe thee softwaree worke together.e e Featuree testinge ise parte ofe thee softwaree
developmente processe wheree thee developerse accesse differente wayse ofe implementinge keye
features.e Thee aree severale reasonse whye youe shoulde doe automatione testinge whiche aree newe
builds,e dependency,e testinge ise requirede toe movee thee applicatione toe thee productione
environment,e ore thee softwaree requirese ae rollback.e Ite increasese thee qualitye becausee ite ise faster,e
cheapere ande cane bee donee moree often.e e Thee advantagese ofe thee manuale testinge ise thee testere cane
teste thee softwaree frome ae usere prospectivee ande gete moree familiare withe thee product.e Whene youe
don'te properlye teste thee softwaree applicationse thate youe develop,e theye wille havee qualitye
problemse ande youre stakeholderse ande userse wille bee verye frustratede ase theye usee thee softwaree
applications.e Goode testinge ande QAe havee toe happene fore thee softwaree applicatione toe meete thee
needse ofe thee stakeholderse ande end-users.
Ie likee toe createe teste planse thate teste worst-casee scenarios.e Testinge edgee casese ande boundarye
conditionse helpse youe finde manye ofe thee worst-casee scenariose whene youe aree testing.e Thesee
testse finde errorse thate tende toe bee criticale withe ae highe priority.e Thesee aree errorse thate muste bee
fixede beforee thee producte ise shipped.Testinge helpse reducee errorse ase testinge wonte eliminatee alle
errors.e Noe mattere howe muche testinge ise donee ite wonte catche alle thee errors.e Evene ife errorse aree
caughte theye mighte note bee fixede ase ite maye causee worsee ore additionale errors.e Whene
organizationse properlye teste theire softwaree applicationse theye increasee thee qualitye ofe thee
applicationse theye develope whiche providese moree valuee toe theire customerse ase theire customerse
usee thesee softwaree applicationse toe solvee theire businesse problems.Automatede testinge shoulde
bee ane essentiale parte ofe anye organization'se testinge ande QAe processes.e Automatede testinge doese
note catche everye bug,e bute whene organizationse updatee theire softwaree applicationse ande makee
changese toe them,e runninge automatione testinge cane helpe toe catche anye bugse thate mighte havee
beene introducede ine thee softwaree applicatione update.e Ite ise goode practicee toe alwayse havee
automatione testinge toe ensuree thate buge fixes,e patches,e softwaree applicatione updates,e etc.e doe
note breake othere arease ofe thee code.e Thise helpse toe increasee thee qualitye ande robustnesse ofe thee
codee beforee ite ise movede toe production.e testinge ise verye importante toe thee developmente process.e
Thee softwaree needse toe bee testede withe reale worlde data.e Thee systeme shoulde alsoe bee testede bye
thee ende userse ande theree feedbacke wille bee thee moste valuablee indicatore ofe howe thee softwaree ise
performing.e Doinge appropriatee performancee testinge helpse thee organizatione toe ensuree thate
theire softwaree applicationse wille performe ase expectede evene duringe heavye volumese ande loads.e
Noe onee likese usinge ae slowe application.e Ife ane organizatione doese note appropriatelye
performancee teste theire softwaree applicatione ande ite ise slow,e userse ofe thee systeme wille gete
frustratede withe ite ande note wante toe usee it.e whene youe aree testinge theree aree differente typese ofe
stagese beforee thee testinge becomese successful.e Ensuringe thate everye stepe workse oute properlye ise
verye importante becausee youe don'te wante toe rune intoe anye issues.e Ife youe doe happene toe rune intoe
ane issuee ine ae certaine areae thene youre cliente woulde havee ae complaint.e Softwaree testinge
identifiese bugse ande issuese ine thee developmente processe soe they'ree fixede priore toe producte
launch.e Thise approache ensurese thate onlye qualitye productse aree distributede toe consumers,e
whiche ine turne elevatese customere satisfactione ande trust.e Testinge ise necessarye ine ordere toe
providee thee facilitiese toe thee customerse likee thee deliverye ofe highe qualitye producte ore softwaree
applicatione whiche requirese lowere maintenancee coste ande hencee resultse intoe moree accurate,e
consistente ande reliablee results.e Ie ame alsoe ae bige fane ofe Unite ande segmente testing.e Testinge
segmentse ofe youre codee firste helpse youe toe bettere pinpointe wheree thee initiale bugse ande QAe
issuese aree ine youre softwaree applications.e Oncee eache segmente ise tested,e youe cane thene movee toe
