Structural Testing
Study slides of structural testing

For each testing
Explain/elaborate definition that I explained in class, make separate heading in examples are
also discussed
Explain/elaborate objectives that I explained in class, separately heading wise (make each point
as headings)
Explain each point of how to - separately heading wise (make each point as headings), I
appreciate if you support with images for explanation

All these testing are essential most and is done in all the software houses

It is done for large volume of

Input
Output
Internal tables
Commands
Disk space
Computer capacity

All these are linked to database, multi user and multi transaction
...

Objective:
The Objective of the Stress testing is that the normal and above normal volume of transactions should
be processed correctly and within time
...
Example:
Dropbox, offline emails and WhatsApp
...
Throughput means “request to transaction” and turnaround time means
“response/return” otherwise it would become the bottle neck
...

Maintain the desired turnaround time:
Users can perform their assigned task but need optimized resources
...

How to do Stress Testing:










The online systems should be tested
...
Examples: Banking transaction
Online in large volume means that all or large amount of instance are active at the same time
and batch systems with respect to pipelining, sequence oriented
...

The test data can be generated by the test group (the group that will collect the data for testing
purpose)
...

The test data can be gathered by making the database values …

But the problem that occurs is that it is a fake data and it will define the performance to some extent
but it is not actual
...

When to Use:





It is done for the applications where the turnover is very huge
...

When the applications can handle the volume of processing without failing
...


Load Testing:
The disadvantages are:



It is very time and resources consuming
In the traditional approach it should be tested before time
...
It verifies the response and the turnaround time and the design performance

How to Use?




It can be done by the by using the hardware and the software monitors (by using the monitors
which displays the performance parameters
...


But the point to be noted is that not the whole system is concerned to the performance
...
In early development process
...
In the early or late modifications
...
Bigger application have more concern of data recovery,
enterprise applications
...

Backup data is stored in a secure location
...

Recovery Personnel should be assigned and trained
...


Point to Ponder:
The backup should be tested after every 6 months
...


How to Use?
In order to use the recovery testing, consider the following points





Place the backup on physically different location/sites and both the locations should have staff
members and the place should be on unattended place
...

Test it by making a dummy disaster
...


…………………………………………………………………………………………………………………………………………………………………
...
The continuity of process is required like where the operations cannot be stopped
...
Need to calculate the cost of loss and backup cost
...

Example:
In defense, they have 100% substitute for everything they have 100% backup for equipment
...
In every country the electricity is required and is made
...
In case
of a natural disaster situation the telecommunication should be operational
...


These are the two main reasons which result in defining the necessity of considering any system necessary
for backup
...
Defense applications
...
Human related applications where the concern is of life and death
...

For the business the data, tools, application and the operating system’s, and their configurations backup
should be made then the backup is considered to be genuine
...
in banking, insurance applications the backup is necessary
...
The operation testing is related to training for the system
...
For the help of the user there are three main areas by which
the help is provided
...
Training
2
...
Documents
All these are provided by the development teams
...
But the
ideal size of the video should be of maximum 3 to 7 MBs
...

There are two types of videos
...
Context Specific help
2
...

General Help: When the user needs the help a “CHM” file is there and the user scrolls and searches the
solution for the occurred problem
...
Years back the “CHM” file were there having the
tags, tags in the video were defined
...
Word file in which the tags were defined of all the controls of GUI application
...
Word file
...

video tutorial
But it is not used nowadays it should be integrated into the video tutorial, the video tagging should be
done
...
But all these
approaches are not practical nowadays
...

Call Center:
Call center approach is applicable to those application which has the client set of more than 10
...


For Example: Many years ago when the internet speeds get heavy or slow and the user asks for help then
the respondent guide the user to open the web browser and checks some of the options and then the
internet gets better but the question is how does he/she able to guide? The answer to this question is the
“User Support Software”
...

Nowadays the call centers have software’s which have the questions like:
For Example: SAP has a customer support and have millions of customers to which they have to respond
they mainly asks for the tools and the interfaces on which they user is currently on and according to that
respond to the user
...
But when the
application is deployed to the customer the tool is not deployed, the flow, procedures and the paths is
defined clearly to the customer
...
The customer
care is also able to send the help to the customer in form of a video tutorial or recording as required to
the provided link in the manual
...
There are two types of the computer operator one the application user and other
is the call center’s help desk
...
The problem
is that the system remains in evolution, in maintenance and gets upgraded and for that the
manual also needs to be updated
...


Job Control Language:
Means the domain jargons, domain vocabulary
...
The person should be literate enough who knows the language and the
task very well
...
It can be taken as to submit
the result or the result has been submitted but want to confirm it
...



The evaluation of the completeness of the operator training should also be conducted and
ensured
...


Example: When somebody calls 117 for the phone number of Bahria University Islamabad Campus then
the respondent will confirms it and will start the recording which will be narrating the telephone number
rather than doing it by himself
...
Like if the person want to record the video and want to send both can be
done
...
Read it
Example: a voice convertor gets the pitch and convert into the desired pitch and listener will get just the
one person that attends always
...

How to Use?





When the requirements are being captured and after that at the prototype phase then the
operational manual is decided, how the user is expecting it, how the user will reach at any desired
point in the application, what are the operational difficulty, when the project will be deployed in
the organization what difficulties and problems will occur
...

It is a final year project, to make an operational trainer
...
The project should have the “Broadcast” option, want to email, the
email option should be there
...
When the feedback of the tool is asked then the most
appropriate video should be provided to the user on the feedback
...


There are many problems in the project, if the other problems are resolved then help is worthy but it the other
problems are not resolved then no matter how good and efficient the help is, it is not useful
...


When to Use?
When you know that the operations will get into production status, if the changes occur frequently then
the call center is not useful
...
Tools will be developed by the development team and the updates will be informed by the
operation to the development team and will update it and also the manual
...

One of the most wanted testing in the software houses I compliance testing, when a software engineer
gets a degree, knows all the standards and is the best programmer, and have many good qualities builds
in because he has 4 years degree and has spent a lot of money means that the person has spent money,
time and energy
...
PM expects that the person coming is a “Guru” but in
reality he/she is not, when he enters the software house many standards are given but if a heavy rule
book is given to somebody then definitely it will only be kept in shelf
...
It is inspected
by Project Manager
...

In Week 1: the naming conventions, template standards are defined to the new employee
...

In Week 3: Submission of Work
...
How to extract, conceive anything,
implement, how to get anything approved, submit anything
...
What are the activities that are conducted
from the requirements to the maintenance? Now the employee get the whole picture
...
Other than his own task
...
This is called Compliance Testing
...
In the project / system should not be effected by the people
entered into the system and the people who resign
...

Every software has its own standards
...

How much documentation is important for the system? Can a system fails because of not having
documentation? Without documentation can a software house be closed? The answer to all these
questions is “YES”
...
For Example CRESSOFT, a software house is the best example
...
But no one can totally be on agile
...

People switches from one place to another place because of either time, money or atmosphere but the
organization survives due to its firm process
...
, where the job on the code is calling, and if then else logic, have a strong
component but the environment is so impressive but there is no development for an individual
...


Objective:
Transfer of people in and out in the organization with minimum cost and maintenance of the project
and to ensure the standards
...


Security Testing;
80% of the security is done due to standards, formulas, tools, hardware’s but all these things are within
the application
...

Objective:
Simple website, SQL injection (Through scripting language) bypass the authentication level it is also the
SQL injection
...

How to Use?
Concern? Whether the user can penetrate then it is the concern if not then it is not the concern of the
teams concern by that the IT specialist will test…
...
Security
is also the major concern of the defense department of any country…
