Transcripts

Hello friends and greetings for the day

welcome back to another tutorial on istb

Foundation level certifications we are

in Chapter 2 talking about testing

throughout the software development life

cycle and continuing ahead with our

second segment that is 2.2 test levels

and test types and as a part of that as

it is a big topic we are still

continuing with

2.2.1 that is test levels and as a part

of this tutorial we'll be picking up the

next level of testing which is component

integration

testing so in the very new labus of

istqb foundation level the board has

merged the integration testing level

into two different parts that is

component integration testing and system

integration testing so don't be worried

and don't be surprised that where is the

integration testing level however in the

reality also the integration testing is

now being conducted into multiple levels

like component integration or system

integration and it's all about that so

that's where in this new syllabus you

will not find a topic called as

integration testing but I will still

give you a quick outline that what does

that even mean but as of today's Trend

we do not have it uh as a standalone

level it just happens at different

further levels so today we are talking

about component integration testing and

component integration testing as the

name suggests is all about inter

interactions or interfaces or

integration between two or more

components within a same module sometime

it can be between modules as well but as

far as it is just limited to two

particular components so in order to

talk about component integration testing

the synonyms what we use for

Integrations are even called as

interfaces interactions or

Communications which are just another

name for integration testing so it is

mainly to test the interfaces or

interaction between the components of a

system also component integration

testing is heavily dependent on

integration strategy approaches like

bottom up top down or big bang

approaches so first of all uh what could

be a quick example to talk about what

should I call it as in component

integration now component integration as

the name suggests it is more of like the

interaction between two or more

components which happens within an

application so one of the right example

is given on the screen right here and

the example here we are talking about a

signup form or a form which allows you

to register yourself on different

websites and here if you notice we have

got three important Fields what we are

talking about that is country state or

Province and city now we all have

experienced filling up this form

ourselves at some of the other time and

we know very well that this particular

option allows us to select a country

first then after selecting a country

then the the state list or Province list

gets optimized or gets listed with those

States and province which are as per

your country selected similarly if I

continue further the states being

selected after that the city list will

be published and without that you cannot

proceed ahead now even if you fill up

all the three Fields And if you go back

to the country and change the the value

of the country then the other two fields

that is state and city will be cleared

and reset to select value now that

totally makes sense and understands that

what exactly interaction is all about

between components so if I consider each

of these drop down Fields as an

individual component I'm having some

kind of interfaces some kind of

interaction or some type of integration

between these components that means

they're not independent anymore but the

other the one set of field depends on

other set of fields value if the value

is incorrect or value is not selected

the other fields will not show show you

any value at all and such examples what

can be very well and easily referred to

what is component integration testing

but is that something which is mandatory

to be conducted in all levels or all at

all type of applications answer is

absolutely not it is not mandatory

subjected your application or your

system have such features embedded in it

then you will conduct this level

otherwise you will move to the

integration level itself which is more

of like the combination of two or more

modules together but not the entire flow

but just two or more modules maybe three

or four and then try to test their

Integrations or interactions yes that's

a slight difference between component

integration and integration testing the

component integration testing is about

interfaces between two or more

components within the same application

or within the same module but

integration testing in general is

interfaces or communication between two

or more modules of an application and in

that context integration can also be

conducted even if you don't have

component integration testing the reason

why istqb has decided to remove that

level from our discussion because

integration is just not one activity to

be conducted it can be between

components it can be between different

parts of system or it can be within

systems that means between systems so

system integration will be the next

level we'll be talking about and

Integrations can happen at many places

not only that if I talk about web

services like apis like rest apis or

soap UPI apis which is like application

programming interfaces now these are

also interfaces thus integration testing

is even conducted here and very well

required to integrate to that of the

application so that the right request

has been processed and right response

has been received and displayed on the

application too so put together there

are such things which we will be talking

one by one keeping this this particular

tutorial simple and to the point we just

limited to component integration the

next topic will be talking about a

system testing following that we will

talk about system integration so that

you can have a wonderful and very

detailed explanation of each one of them

so that's all from this particular

tutorial team should you have anything

else feel free to comment below I'm

always there to address your queries and

answer them well till then keep learning

keep exploring keep understanding the

context thanks for watching the video

team and happy

learning
