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.
Testing Environment Flow:
BRS-BUSINESS REQUIREMENT SPECIFICATIONS
SRS-SYSTEM REQUIREMENT SPECIFICATIONS
FRS-FUNCTIONAL REQUIREMENT SPECIFICATIONS
HLD-HIGH LEVEL DESIGN
LLD-LOW LEVEL DESIGN

Software Testing: It is a process of verifying are we developing a right product or not and also validating does the developed product is right or not.
Software Testing = verification + validation

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
The main protagonist for this story is Mr. Waythorn, he is the third and current husband of Alice Waythorn and the story is mostly told from his perspective. He is the main character of the story and works with Alice's second husband, Gus Varick. He is also the stepfather of Lily who is the daughter of the first husband of Alice; Mr. Haskett. He looks beyond the social stigma of marrying a woman who has been twice divorced. We see throughout the story Mr. Waythorn’s character undergoes some changes in the way he views his wife and her past relationships thereby making him a round character. Mrs. Waythorn is the antagonist of this story, it is obvious that the she has used all her marriages to advance her social standing, she redefines herself based on the level she attains, thereby refining who she is to those around her. We see all this from the perspective of her husband. After the glow of the honeymoon has died down Mr. Waythorn begins to realize that his perception of who Alice was before they got married was probably wrong. Alice is revealed to be more complicated as a character than we are initially presented with based on the perception of her current husband, so for this reason she is a round character.

Making a good and persuasive argument is very much an acquired skill. It requires much practice and perfecting. It takes more than just having passion and making good points. Just because a person is passionate about the topic or has supporting details does not mean they can make a successful argument. Much more thought and skill is required. Gordon Adams, in his letter to the Arizona State University standards committee, demonstrates this quite well. Gordon Adams writes a passionate argument, yet his argument lacks several critical aspects.
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.
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.
Software - the programs or language that controls the functioning of the hardware. Table of contents - a section on a CD that lists the locations of files to help a computer locate data.
Testing software test the absence of errors in the software, but in reality it only checks the presence of software errors but never guarantees their absence. Software testing cannot prove absolutely the absence of errors, which are detected by discovering their effect. still problems might be to decide when to end testing the software.
... 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.
Interface Testing- This form of testing would be done to make sure that the systems pass data and work fluently together.
Software Process: The process is a required part of any discussion on software development. Software development occurs over many phases, requiring many different skills. The process is a management tool for making sure that everything gets accomplished. One issue with using a process is avoiding the tendency to over-regulate or bureaucratize the engineers and thus impact their sense of respect and positive responsibility. [[1]]

Testing constitutes one of the most important aspects of software development or most important phase in the software development life cycle. Out of many different types of software testing, acceptance testing is a test conducted to determine if the requirements of a specification or contract are met. The acceptance testing is defines as: formal testing with respect to user needs, requirements, and business processes conducted to determine whether a system satisfies the acceptance criteria and to enable the user, customers or other authorized
Software testing is the “process of executing a software system to determine whether it matches its specification and executes in its intended environment” (Whittaker 71). It is often associated with locating bugs, program defects, faults in the source code, which cause failures during execution that need to be removed from the program. Locating and removing these defects is called debugging, which is different from the testing that establishes the existence of these defects. Specifications are crucial to testing because they identify correct behavior so that software failures corresponding to incorrect behavior can be identified. Failures can vary in their nature ranging from wrong output, system crash to systems using too much memory or executing too slowly. These Bugs in software can be due to untested code executed, u...
From those requirements, the test engineer must develop an adequate system-level test solution and provide a comprehensive test coverage report, which details each test case and if it was adequately tested. This report is typically made available to the customer or client to aid in understanding the risk associated with the final avionics system overall. The final test coverage report is perhaps the highest culmination of diligence, technical competence, integrity, and collegiality for a test engineer, especially when testing flight critical systems. The engineer must have the technical competence to understand the drawbacks of their custom testing systems, the diligence to correctly adhere to all communicated testing requirements, and the integrity to report any test case that is not covered in the test coverage report. Additionally, when their test system is entered to the production floor to being rigorous testing of avionics systems and a device under test (DUT) fails a test case, especially if this device is critical to flight due to schedule or cost such as a flight controller, they must have the integrity and competence to decide the fate of that DUT. This combination of these virtues, falling under virtues of thought or characters, are effectively what lead to the “good life” or flourishing for test
