Types of Software Testing
Feb 17th
Types of Software Testing can be defined under different categories. The most common types of software testing are are as follows.
On the basis of time testing is executed in the Software Development Life Cycle:-
Unit Testing
In the most simplest terms, Unit Testing refers to testing of individual software components or modules. Unit testing in the implementation phase can result in significant gains in software quality. If unit testing is done properly, later testing phases will be more successful.
General assumption about Unit testing is that: Unit testing is done primarily by the developers and test engineers need not know about Unit testing. But this is not the case, Unit testing is as important for test engineers as it is for developers.
Probably developers will write the unit test cases but tester’s understanding of the framework and unit testing can certainly help him/her in designing the flow for unit test cases, generating test data and making good reports. All these activities will ultimately help a tester in the long run as product quality will increase significantly because of the efforts a tester put in on the unit testing.
Integration Testing
Integration Testing is referred as the phase of software testing in which individual software modules are combined and tested as a group. It follows unit testing and precedes system testing. Integration testing is the testing of combined parts of an application to determine if they function together correctly. The ‘parts’ can be code modules, individual applications, client and server applications on a network, etc. This type of testing is especially relevant to client/server and distributed systems.
Integration Testing can be classified in three different ways based on the from where the testing is started and in which direction it is progressing.
>Big Bang Integration Testing
>Top Down Integration Testing
>Bottom Up Integration Testing
>Hybrid Integration testing
System Testing
In the most simplest terms, System Testing can be defined as the process of testing an integrated system to verify that it meets specified requirements.
System Testing phase is started after the completion of other phases like Unit, Component and Integration testing. System Testing aims at testing both functional and non functional requirements.
System testing is a black-box type testing that is based on overall requirements specifications; covers all combined parts of a system.
The following tests can be categorized under System testing:
1. Recovery Testing.
2. Security Testing.
3. Stress Testing.
4. Performance Testing.
System testing should be conducted by an independent testing organization to ensure the system is stable and meets minimum quality criteria before proceeding to UserAcceptance test.
User Acceptance Testing:- UAToccurs just before the software is released to the customer. The end users along with the developers perform the User Acceptance Testing with a certain set of test cases and typical scenarios.
Acceptance testing is designed to determine whether software is fit for use or not. Apart from functionality of application, other factors related to business environment also plays an important role.
User Acceptance Testing could be in the form of:-
Alpha Testing – Where test are conducted at the development site by the end users. Any type of abnormal behavior of the system is noted and rectified by the developers. Environment can be controlled a little bit in this case.
Beta Testing – Where test are conducted at customer site and development team do not have any control on the test environment. In beta testing, users play the role of testers. The beta test is a live application of the software in an environment that cannot be controlled by the developer.
In both the cases, these testing might be assisted by software testers.
User Acceptance Testing – prerequisites/Entry Criteria:
Before the User Acceptance testing can be done the application is fully developed.
Various levels of testing (Unit, Integration and System) are already completed before User Acceptance Testing is done. As various levels of testing have been completed most of the technical bugs have already been fixed before User Acceptance Testing(UAT).
Acceptance plan is prepared and resources have been identified.
User Acceptance Testing – Exit Criteria:
Acceptance decision is made for the software
In case of any caveats, development team is notified
User Acceptance test should be conducted by the end users of the system and monitored by an independent testing organization. The Users must ensure the system is stable and meets the minimum quality criteria before proceeding to system deployment (roll-out).

Types of Outdoor Grills
Jan 23rd
Barbecuing outside is a number a method to make excellent food and have a fab time. There are a lot of options out there for grilling. Out of doors griddles can range from the simple to the elegant.
A free standing out of doors griddle is an easy standard that works really well in places such as out of doors parks or apartment complexes. The standard griddle is just a grill and a box, with perhaps some shelves for food and tools, and handles for moving and turning a hot grill. These grills are superb for community areas because they’re easy to clean up and do not require any additional upkeep from the owner for supplying propane or gas.
griddles only get more complex than the free standing grill. Gas powered grills for the home or terrace are built with a number of components that make barbecuing outside just as if not more exciting than cooking in the kitchen. Gas grills regularly have 2 griddling levels, so it can cook beef as well as plant, and heat breads all at the same time. Some are also equipped with a stove eye, so it can cook potted food like beans.
Both kinds of griddles can be dressed up even more by rock or brick work. Once a perfect grill and perfect site have been chosen, give it an enduring, protected home in rock. This may simply be done as a weekend project. All that’s needed is a flat of bricks or rocks, a bag of cement or mortar, and some simple tools. Using rock work to house a griddle protects the outside griddle and also gives it a singular look that may make griddling outdoors even more enjoyable.
out of doors grills are available in many shapes and sizes. Shop around to discover which type of out of doors griddle is best for your outdoor setting.
