Now a days most carefully planned and designed software contains some defects. The Main aim of testing is to identify these defects. It also checks faults, errors, failures, and bugs in specific designed software. It requires creating and executing many tests. Software testing is the mensuration of software quality. The quality of the specific software can be achieved by the factors such as Correctness, Reliability and Testability.
Software testing can be performed in two ways. They are
1.Conventional Testing.
2.Unconventional Testing.
Conventional Testing: In this type of testing, the testing is started after the coding.
Unconventional Testing: In this type of testing, the testing is done from the initial phase.
Software: A software application is a set-up of computer program and minimal data in order to operate a system is called software. Example-Accounting Software and Emailing Software
Project: If a software application designs for a specific client, then it is called project. Product: If a software application is design for multiple clients, then it is called a product.

Test Case: A Test case is a set of pre conditions, test scripts, input data and expected results to validate functionality in the system.
Types of test cases
1) Positive Test Case: If a test case is prepared to check what system supports to do like check LOGIN with valid inputs
2) Negative Test Case: If a test case is prepared to check what system not supports to do like to check LOGIN with invalid inputs.
TEST EXECUTION: Executing a formal test or informal test cases to confirm the business requirements and to identify the defects is called test execution.
BUILD RELEASE PROCESS: As per the build release date already planned developers will release the build to testing team along with every build release we receive 2 documents they are software requirement notes and deployment document
BUILD: An executable application is called Build
After the coding activity is complete the next process is to test the program and make sure it works correctly. First programs are tested in groups and then the entire system is tested as a complete unit (Shelly, Cashman & Rosenblatt, 1998). Our testing phase started with a few local computers that were set aside strictly for this purpose. As the project got further along other departments were brought into the picture. First they started with departments that were located at the main campus. Once those tests were complete they need to test department from off campus. The system needed to be check to make sure user records were shown so accounts could be tracked and reported if necessary. Other test included a network load test to insure it could handle the amount of computers that were going to be put on the system. Many other tests were most likely put into place before the system was offered to other departments like ours. Once the testing phase was complete it was time to move on.

Abstract— Software testing is very important element in various product accuracy. Software testing is set of activities conducted with the intent of finding errors in software. It also verifies and validate whether the program is working correctly with no bugs no not. There are basically three levels of testing- Unit, Integration and System. Unit testing referred to as testing in small whereas Integration and System testing are referred to as testing in large. Various testing techniques available for designing of test cases. This paper basically deals with various techniques available to design software testing test cases.
Software systems are discrete-state systems that do not have repetitive structures. The mathematical functions that describe the behaviour of software systems are not continuous, and traditional engineering mathematics do not help in their verification." In other words some software can be so large that thorough testing can be almost impossible and so bugs in the software can go unnoticed. An example of this was when an Atlas-Agena rocket veered off-course when it was ninety miles up. Ground control had to destroy the $18.5 rocket.
The software testing is the critical element of software quality assurance and represents the Ultimate review of the software design and coding. The main objective of testing is to find an error and to uncover the errors that are not yet discovered.
A test can be defined as a procedure intended to establish the quality, performance, or reliability of something, especially before it is taken into widespread use. As a society, people are tested at every stage in life whether it be a written or a practical exam. Since our first year in an educational institution, we are tested at least once a week for every subject we study. We continue these vital practices of testing all the way through schooling into lifetime careers. Testing is a way for the teacher or other higher position to assess the level of skill and mastery one has over a given material. This task is important to determine if the person is qualified for the next step or a next career. Arguably, the most important careers require
Integration testing comes before system testing and after unit testing has been completed. The integration testing stage will make developers aware of any errors produced due to the system or the script. The integration testing phase seeks to confirm that the integration of the components is fruitful and that it runs effectively, devise a test plan, and collect test case data produced to efficiently test that the integration is efficacious.
The initial step is to make a test and add it to the test suite. The primary motto is to make the code fail and pass after making certain changes to it. After the case has passed, another set of tests are being added and dealt in the same fashion one at a time. So one requires basic understanding of ...
Delivering a quality product is not solely down to how good the developer is, even though that helps, it is down to the quality of the original analysis and understanding of the requirement. Software testing is carried out to provide developers with a report on the quality of the program or application under testing. It allows the business to get an objective and informative view of how the product works. The purpose of testing is to resolve as many issues as possible before it is released. Each of the following testing principles help play a part but collectively they look to provide a working solution.
Software testing is a process to improve the quality of software because software which is error-free, user-friendly and provides client satisfaction is considered to be high quality software. It is a vital part of Software development in providing a quality software product i.e. bugs free. Software testing is the process of working out or calculating a system or system components to identify if it satisfies specified requirements or to identify the difference between expected or actual results. It is also defined as a process in which the business and technical requirements of the product are accordingly validated and verified. Testing of software is important to be done carefully and efficiently for deployment in order to retain
Software development follows a specific life cycle that starts with designing a solution to a problem and implementing it. Software testing is part of this software life cycle that involves verifying if each unit implemented meets the specifications of the design. Even with careful testing of hundreds or thousands of variables and code statements, users of software find bugs. “Software testing is arguably the least understood part of the development process” and is also a “time-consuming process that requires technical sophistication and proper planning” (Whittaker 71) It is important to comprehend this concept by understanding the different characteristics and aspects of software testing, and then to examine the techniques, procedures and tools used to apply this concept. This will enable the user to realize the problems faced by software testers and the importance of software testing.
... testing team validates structured and unstructured data of large volume. Obtaining timely and meaningful information is difficult, if not possible, often hampering decision making and in many cases the cost of obtaining information is prohibitive. Organizations faced with this situation must fully realize the benefits of a big data initiative, create an effective test strategy and appropriate test environment as part of their overall validation strategy.
Automated testing is a testing tool to test the software automatically rather than doing manual. It consists of pre-scripted tests to perform on software application in order to test it. We can compare both expected and actual result to generate detailed test reports. The main intention of this automation test is to decrease the number of test cases that run manually and it would not exclude manual testing all together. Once the test suited is automated, no human intermediation is required.
A software development methodology is a standard proven process which helps programmers, architects, system analysts and others to make a well controlled and an efficient progress in the high quality software development.
