Слайд 2 Manual and Automated
Manual testing is the process through

Manual and AutomatedManual testing is the process through which software developers

which software developers run tests manually, comparing program expectations

and actual outcomes in order to find software defects

Automated testing is the process through which automated tools run tests that repeat predefined actions, comparing a developing program’s expected and actual outcomes.

Слайд 3 Verification and Validation
To ensure that work products

Verification and Validation To ensure that work products meet their specified

meet their specified requirements.
To ensure that the product actually

meets the user’s needs, and that the specifications were correct in the first place.

Are we building
the product right?

Are we building
the right product?


Слайд 4 Positive and Negative

our intention is
In

Positive and NegativeIn positive testing our intention isIn negative testing our

negative testing our intention is
to prove that an application

will work on giving valid input data. i.e. testing a system by giving its corresponding valid inputs.

to prove that an application will not work on giving invalid inputs.


Слайд 5 Black-box, White-box, Grey-box
Black-box Testing is a software testing

Black-box, White-box, Grey-boxBlack-box Testing is a software testing method in which

method in which the internal structure/ design/ implementation of

the item being tested is NOT known to the tester.

White-box Testing is a software testing method in which the internal structure/ design/ implementation of the item being tested is known to the tester.

Grey-box Testing is a software testing method which is a combination of Black-box and White-box Testing methods.


Слайд 6 Testing the attributes of a component or system

Testing the attributes of a component or system that do not

that do not relate to functionality.
Non-functional characteristics are:
Performance efficiency
Compatibility
Usability
Reliability
Security
Maintainability

Testing

based on an analysis of the specification of the functionality of a component or system.

Functional testing

Non-functional testing


Слайд 7 Functional testing Example #1
Verify adding of two numbers

Functional testing Example #1Verify adding of two numbers (5+3 should be

(5+3 should be 8);
Verify subtraction of two numbers (5-2

should be 3);
Verify multiplication of two number (5*3 should be 15);
Verify division of two numbers (10/2 should be 5);
Verify getting radical of some number (√25 should be 5);
Verify multiplication of some number by zero (5*0 should be 0);
Etc.

Слайд 8 Smoke testing
A subset of all defined/planned test cases

Smoke testingA subset of all defined/planned test cases that cover the

that cover the main functionality of a component or

system, to ascertaining that the most crucial functions of a program work, but not bothering with finer details.

Regression testing

Testing of a previously tested program following modification to ensure that defects have not been introduced or uncovered in unchanged areas of the software, as a result of the changes made. It is performed when the software or its environment is changed.

Sanity testing

Sanity testing is a kind of Software Testing performed after receiving a software build, with minor changes in code, or functionality, to ascertain that the bugs have been fixed and no further issues are introduced due to these changes. The goal is to determine that the proposed functionality works roughly as expected. If sanity test fails, the build is rejected to save the time and costs involved in a more rigorous testing.


Слайд 10 Performance testing
Testing with the intent of determining how

Performance testingTesting with the intent of determining how efficiently a product handles

efficiently a product handles a variety of events.
Purposes:
demonstrate

that the system meets performance criteria;

compare two systems to find which performs better;

measure what parts of the system or workload cause the system to perform badly.

Слайд 11 Load testing
A type of performance testing conducted to

Load testing	A type of performance testing conducted to evaluate the behavior

evaluate the behavior of a component or system with

increasing load, e.g. numbers of parallel users and/or numbers of transactions, to determine what load can be handled by the component or system.

Purposes
evaluation of performance and efficiency of software

performance optimization (code optimization, server configuration)

selection of appropriate hardware and software platforms for the application


Слайд 12 A type of performance testing conducted to evaluate

A type of performance testing conducted to evaluate a system or

a system or component at or beyond the limits

of its anticipated or specified work loads, or with reduced availability of resources such as access to memory or servers

Purposes:
the general study of the behavior of the system under extreme loads

examination of handling of errors and exceptions under extreme load

examination of certain areas of the system or its components under the disproportionate load

testing the system capacity

Stress testing


Слайд 13 Localization is the process of adapting a globalized

Localization is the process of adapting a globalized application to a

application to a particular culture/locale.
Internationalization is the process

of designing and coding a product so it can perform properly when it is modified for use in different languages and locales.

Localization (L10N) testing checks how well the application under test has been Localized into a particular target language.

Internationalization (I18N) testing checks if all data/time/number/currency formats are displayed according to selected locale and if all language specific characters are displayed.



Localization & Internalization testing


Слайд 14 UI Testing
The testing a product's graphical user interface

UI TestingThe testing a product's graphical user interface to ensure it

to ensure it meets its written specifications
Check if any

UI recommendations exist for the application type your team develop. Make sure dialogs you test comply with these recommendations.

Слайд 15 Compatibility Testing
Compatibility testing is used to determine if

Compatibility TestingCompatibility testing is used to determine if your software is

your software is compatible with other elements of a

system with which it should operate, e.g. Browsers, Operating Systems, or hardware.

This type of testing helps find out how well a system performs in a particular environment that includes hardware, network, operating system and other software etc.
It tests whether the application or the software product built is compatible with the hardware, operating system, database or other system software or not.


Слайд 16 Usability Testing
Usability testing a non-functional testing technique that

Usability TestingUsability testing a non-functional testing technique that is a measure

is a measure of how easily the system can

be used by end users. It is difficult to evaluate and measure but can be evaluated based on the below parameters:
Level of Skill required to learn/use the software. It should maintain the balance for both novice and expert user.
Time required to get used to in using the software.
The measure of increase in user productivity if any.
Assessment of a user's attitude towards using the software.

Слайд 22 Alfa & Beta Testing
Alfa testing takes place at

Alfa & Beta TestingAlfa testing takes place at the developer's site

the developer's site by the internal teams, before release

to external customers. This testing is performed without the involvement of the development teams.


Beta testing also known as user testing takes place at the end users site by the end users to validate the usability, functionality, compatibility, and reliability testing.

Beta testing adds value to the software development life cycle as it allows the "real" customer an opportunity to provide inputs into the design, functionality, and usability of a product. These inputs are not only critical to the success of the product but also an investment into future products when the gathered data is managed effectively.

Waterfall model

places emphasis on documentation
Waterfall model has simple approach and is more disciplined
Easily identifiable milestones and deliverables
Track progress easily due to clear stages

Inflexible: difficult to respond to changing requirements
No working software is produced until late during the life cycle.
Some problems in requirements, design and coding might be not discovered until system testing
Defects cost is high

Easily identifiable

milestones and deliverables
Testing activities like planning, test designing happens well before coding. This saves a lot of time
Proactive defect tracking – that is defects are found at early stages when they are introduced

Rigid and Inflexible: difficult to respond to changing requirements

If any changes happen mid way, not only the requirements documents but also the test Documentation needs to be updated

No working software is produced until late during the life cycle.
