Test Driven Development
The Test first development technique where the test is written before the code. One view of the technique is that it helps understand the requirement better and is not so much about validating the requirements. The basic idea is that the code once written should validate all the requirements which is achieved by a process just reverse to the conventional approach. This section covers the importance of TDD, how to put TDD in practice and the references which provide standard view of the approach.
Importance of TDD
1. The final or resulting functionalities can be delivered with ease since the code is being developed with smaller fragments and thoroughly tested. So the resulting implementation does not tend to be complex. [1]
2. The time required for product development is significantly reduced as well. One need not wait for the end to test the whole functionality. The same has been tested in bits and pieces all the way.
3. Since after every set of tests the code is being developed to pass them, the regression [1] tests actually are conducted on that piece of code. The code is written in such a way so that it can be delivered as is, so the reviews at the end tend to be a lot easier. The approach gives the code a modular view and the final code reviewer can make a sense of each module being developed.
Training Objectives/How to go about TDD
1. 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 ...

...ex methods with a large pool of data which would be nothing but the stress testing of the application developed.
9. The best practices for developing such test methods should be strictly followed for eg. in [4] it is clearly mentioned that methods should not accept any arguments and should not be committing changes to any attribute in the database.
10. JUnit test cases which use methods like assertEquals(), assertSame() makes use of the objects and not the parameters in function to determine the value being returned. So the basic framework of how JUnit test cases work should be part of the training program.

Advantage: providing more opportunity to customers to be aware of and buy UA products; increase sales in the long run.
Develop a test strategy for testing the entire application chosen in unit 3 for analysis and design. Keep in mind that testing that involves users should minimize their time commitment while obtaining essential information from their involvement. Specifically define roles, responsibilities, timing, and test strategy for each level of testing.
It is composed of several steps, it starts with observations. Observations are where a person collects known data concerning what you are going to test on. Next they formulate a hypothesis based on their observations. After they have a hypothesis they perform several experiments to prove or disprove it.
Testing must be performed on a pre-established schedule and will be executed under supervision of the qualified individual to validate the sampling; besides, must be implemented by third party testing services, and the Instruments used for analysis should be calibrated in accordance with established procedures.

The first step to define the project is to check its feasibility. After testing the feasibility, requirements are gathered. The requirements phase focuses on what the software will do in an effort that views all stakeholders, including potential users, as important sources of information. The design phase considers the overall structure of the software and defines the strategy for its development. The requirements and design phase are believed to be the most critical part of the SDLC. Any flaw in this phase may prove very expensive for further stages of the life cycle. (Catherine, 2006) Once you have the design down the next step is to build the application. Testing is another crucial stage of SDLC that determines how the application functions and if it’s effective. This phase also identifies bugs or errors that are in the software. After the finished software is fully developed and tested it’s time for the installation. Once the application...
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.
There are many solutions to these problems, but none of them are easily implemented. Each area of testing should be heavily modified. In math, for example, there is a str...
The benefits of the products for consumers are that they now have an opportunity to customized things that they may like or make something
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.
It provides significant efficiencies in cost and delivery in exchange for minimal customization and represents a shift of operational risks from the consumer to the provider.
