Hello friends and greetings for the day

welcome back to another tutorial on

istqb Foundation level certification we

are in chapter 6 talking about test

tools and continuing ahead with our next

segment that is 6.2 benefits and risk of

test Automation and as a part of this

tutorial we'll be trying to understand

is it so simple or difficult to make use

of a tool

[Music]

looking at the trend most of the people

quite often think that using tools must

be simpler easier and adaptable at any

point of time and that's where it

becomes a very complicated thing to

blindly go for a tool and this

particular segment is going to help you

understand that what are the purposes

and benefits of having tool being used

into your organization and process and

at the same time we'll be also looking

at what are the complicated risk

involved which one one should look

forward to mitigate well ahead of time

before adopting a tool within the

process and project because it could

turn out to be a risk and could turn

into a disaster in your project so let's

not waste our time and quickly look at

some of the benefits quickly and then

we'll talk about the risk also involved

in using a tool so benefits are very

straightforward and uh we talk about the

benefits as simply acquiring a tool does

not guarantee success each new tool will

require effort to achieve real and

Lasting benefits for example for Tool

introduction maintenance and training

there are also certain risk which we'll

be looking into and someone should look

forward to mitigate that now potential

benefits of using test tools are very

well understood number one the time

saved by reducing repetitive manual work

and that's one of the very common

benefit of having an automation testing

tool or any tool so generally here we

are talking about the blend of using

tools and automation testing tool do

your benefits and risk will be from both

the sides so number one point is related

to repeative manual work is relating to

the automation test tool so of course we

understand that if there are tests which

we have to repeat again and again it

will certainly be very hectic to do

manually for example if you talk about

the regression testing is something

which is very good candidate of

reputation and thus consumes a lot of

time because over a period of time it is

expected to grow bigger in size thus

it's a very good candidate of automation

as well and that turns out to be one of

the key benefit of having automation

testing being in use also another

benefit we have here is prevention of

simple human errors through greater

consistency and repeatability now this

is more of like related to test

management tools or any other automation

tools as well for example if I'm talking

about automation testing tools we follow

certain Syntax for the languages which

prevents human error right because in

manual testing we say that different

users can perform it differently but

when there are scripts written it always

maintains a consistency thus it prevent

vents human errors while writing it in

terms of syntax and even when it comes

to systematic arrangement of data into a

test management tool it's more of like

the tool will only drive the things

according to the need of the tool that

is the fields to be filled up there's a

drop- down value to be picked up so

instead of people mentioning things in

Excel sheet thus tool gives you another

benefit by just having things being

managed systematically or being

consistent in their executions or

maintenance further to add here another

benefit is more objective assessment and

in providing measures uh that are too

complicated for human to drive now for

example if you remember in chapter 4 we

covered some of the coverage

measurements like statement coverage and

decision coverage when we had a simple

program we could do it easily with the

flowchart but when it is complex what if

it is a very big program then certainly

it's not something which is easy for a

human mind to do it manually in that

context we do have tools which are very

capable of doing such evaluations and

helping you get the required coverage

within no time and simply when we talk

about the linkage like Trace abilities

or tracability matrices you may not have

enough time to map 100 requirements with

respect to that of 400 test cases one by

one and that's where a test management

tool could have this capability of doing

systematic measurements or more uh

specific assessments which are sometime

very complicated without having the tool

plus to add here of course easier ACC

access to information about testing to

support test management and test

reporting of course uh having test

management tool will help you get

everything what you need at any point of

time being managing all your resources

in a very systematic Manner and at the

same time can compile things together to

build a wonderful report which can

reflect coverages and executions and

many other things related to different

uh parameters like defects risk Etc so

test management tools again adds this

benefit finally we also talking about

reduced test executions time to provide

earlier defect detection faster feedback

and faster time to Market having said

that being automation testing tool user

you do understand yourself that it is

very simple and faster if you have

automation Tools in practices because

most of your manual efforts can be

reduced and it turns into a big and fast

change into your project th releasing

tools well ahead of time also to add

here more time for testers to design new

deeper and more effective test and

compiling all the benefits together we

would say that if all together these

benefits are achieved by your tools then

certainly the testers have enough time

and more time given to them to think

about the various scenarios or adding

additional test cases rather than

wasting their time doing executions

manually so put together there are

several benefits of having tool being

used into the organization that turns

out to be a great benefit for any

organizations but they're not just

limited to benefits before or we

mitigate all the risk so let's talk

about the risk on the other hand if I

talk about the risk these are those risk

which one should understand identify

well ahead of getting or procuring a

tool for the organization or even for a

project in those terms all we are trying

to say that if these risk are identified

and mitigated well in advance your

experience of interacting with the tools

within the organization and the project

would be less risky or no risk at all

but sometime there are risk which you

understood in our chapter 5 that they

may not be mitigated but have to be

accepted so let's quickly check out what

other the risk we are talking about

related to the test tools which includes

test management tools and test

automation tools as well so number one

here the potential risk of using test

automation may include unrealistic

expectation about the benefits of tool

sometime you thought that is as simple

as downloading it from Google installing

it and getting started with it but as

you do talk about some of the

complicated tools they may not be easy

to use and thus they may need a proper

training proper time given for people to

learn about a programming language or

maybe sometime it could be hectically

involved in configuration on the servers

or setting it up together to in order to

start using it so it's not necessary

that uh every single tool is very user

friendly sometime you need to really

know in and out about the Technologies

before making use off a tool also to add

uh inaccurate estimations of time cost

effort required to in reduce a tool

maintain test scripts and change the

existing manual test process see all the

three aspects have been discussed when

we talk about the cost time and effort

required to roll out a new tool one

should really understand however let me

remind you these are the responsibility

of the test manager that is to select a

tool and roll out a tool into the

organization so the team will not be

involved but manager given that they

have wide experience of such tools they

would be already taking care of that but

the cost time and required should be

calculated because you cannot expect

your team to be well groomed with any

type of tool blindly so you must give

them enough time cost involved in buying

the tool or doing the training

mentorship Etc you cannot expect return

on investment right from the day one of

getting a tool right and effort the team

has to apply those effort they have to

get used to it they have to get you know

practicing with it and that's where they

start returning the benefit so never

underestimate the things related to cost

time and effort uh with respect to

rolling out a tool for the first time or

if you are already having manual test

cases and you want to migrate to

automation the efforts are different so

all these can be taken into a risk the

next one here is using a test tool when

manual testing is more appropriate is

it's not a fashion to use a test tool

it's just that it's a need so if you

think your organization is really

wasting a lot of time doing it manually

and there is a solution you have a

budget you have enough approvals for

that then you can certainly go for it

okay it's just more about the need it's

not that if your manual is doing better

than automation then you still adopt

automation tool unnecessarily spending a

cost so it's very important to take all

this point into account also to add here

uh relying on a tool too much that is

over Reliance so over Reliance simply

means that you bought a watching washing

machine automated washing machine and

you thought that when you leave for work

the machine will roam around your house

and pick up the dirty clothes and start

washing them not that doesn't happen

right so it's more of like letting you

know that a tool will only do what you

instructed to in fact there will be

still some manual efforts required

writing the scripts giving the data

defining the control flow and then even

clicking the play button which is to run

the script right so exactly the same

thing no over Reliance on the tool tools

will only do what you ask them to do and

they still need the

prerequisites okay the next one here is

the dependency on the tool vendor which

which may go out of business retire the

tool sell the tool to a different vendor

or provide poor support most of the time

it's not necessary that the tool only

creates the problem in your project

sometime the tool provider could also be

a problem sometime becoming a very big

brand and buying the tools from these

big Brands could be a challenge because

they do not take care of the feedbacks

the support tickets Etc uh when it comes

to the need of the organization so

sometime having poor response or

sometime you bought it from a new vendor

just because he was was giving you

promotions and a lot of offers and

tomorrow he shut down his office okay or

retire the T saying that oh we are no

longer maintaining it we not giving any

kind of updates on this so you are stuck

because your project is ongoing and half

of your script is already there in the

script uh in the tool so you must

evaluate the vendor strengths weaknesses

and their support on your tickets before

getting the tool the next one here is

using an open source software which may

be abandoned u meaning that no further

uh updates are available or as internal

cence may require quite frequent updates

as of further development so open source

tools as we all understand it's a freear

people don't really have to pay a cost

for it all you need is a GNU license and

you can go ahead and use it which is

public open license and uh the problem

with this these type of tools is that as

they're freeware they're not charging

you anything so they may suspend it any

time or they may not look L not not look

forward to give you any kind of updates

right or sometime to frequent updates

that means you have to take care of the

configuration parallely which could be

an extra overhead so that's where we

need to keep all these things into

account and then mitigate them or have

some plan of action for them before

blindly opting for it also to add here

the automation tool is not compatible

with development platforms sometime it

may happen that you buy a tool X and you

know that you are testing an application

based on Java and then X does not

support Java so you are almost done

there right so you must always do a PO

which is proof of concept to check that

the tool which you're looking forward to

adopt does it work with your technology

does it work with your platform or even

sometime the operating systems can be

taken into this account for example you

have a tool which you are working on

Windows 10 tomorrow Windows releases

Windows 11 and your windows says no no

this tool doesn't work on Windows 11 so

your company is going to migrate to 11

but some of your tools are not capable

or compatible with that so all these

part part basically comes into this

point itself the technology the language

what you use into your development uh

whether the tool is capable of testing

it and the base platform where you're

going to install it right and last but

not the least choosing an unstable tool

that did not comply with regulatory

requirements or safety standards so

again from the software and Hardware

industry point of view both the points

are mention here that even the

compliance is equally important the

regulatories what is recommended

recomended what is not recommended so

your legal team your security team will

be interfering now and then evaluating

and asking you what are the policies of

this tool can we protect it or will this

retain our data so those regulatories

and compliances are important and same

goes with the hardware industry or

Automotive Industries where we are very

very restricted to the use of tools what

we can make use of in our projects so

put together these are all those risk

which we should take into account prior

to getting a tool not after that and if

you can plan for mitigation and have

some mitigation action handy that's

where you go for a tool okay so put

together that's all from this particular

tutorial team and should you have

anything else feel free to comment below
