Is It necessary to Test the Software OR what is the reason to test the software.

To answer the earlier query (s), let's look at the nature of application testing. The group is a application testing service provider. testers provide valuable information & ideas on the state of the method. This information helps to reduce ambiguity about the method. For example, to pick whether to launch a product, decision makers require to know the status of the product, including such aspects as the product complies with the requirements, the usability of the product, any known risks, the product conformity to any legislation applicable, etc. The application testing allows an objective assessment of the degree of method compliance with the requirements & specifications.
Tests confirm that the method complies with different requirements, including functional, performance, reliability, security, user & so on. This test is done to be sure that they are building the right method. In addition, testing validates that the method under development is what the user needs. In essence, validation is done to be sure that they are building the right method. In addition to helping make decisions, the application test information to support risk management.
Application testing helps improve product quality. While finding faults / mistakes is one of the purposes of testing application, not the only purpose. It is important that application testing to confirm & validate that the product complies with the requirements & specifications. Quality improvements help the organization to reduce costs of post-release support & service, while generating customer goodwill that might lead to increased revenue opportunities. Moreover, in situations where products must be sure compliance with regulatory requirements, testing of application to enable to preserve the organization of legal responsibility for verifying compliance.

Why Do Client find bugs that is missed by Tester?

Here's a familiar scenario: Testers take months or more, facts of a product. One time the product is launched, users document bugs that were found by the test team. The obvious query that arises is - how did the test team miss out on these issues?
Here are a lot of the reasons why users capture issues that the application testing team may have lost.

Diffrence between Quality assurance,Quality control and Testing

Software Testing is one of the techniques of quality control. Other techniques include quality control, inspections, and reviews, walk-through of work products such as requirements, design, code and documentation.
Quality control aims to make sure that the quality of work and quality results will be constructed before work is completed. Quality control focuses on the ability of a method to produce or distribute a product or service quality. QC's purpose is to select the quality of work was completed after the work is completed. For the application quality assurance function may involve control of the application against a set of requirements and confirm that the application meets the requirements defined. QC analyzes the results of a method to select the extent to which conforms to expectations. The "control" in the QC is based on detecting issues with a product, or the capture of "poor quality" before sending to customers. Put another way, when there's cases of quality control "poor quality" implies that the group has invested resources and time to produce a product that has poor quality built in.

Agile Development

Agile is a program development technique in which program is developed in short timeboxes. Each timebox called Dash. Each race is usually 30 days. little or little change function will be developed in each dash. They must plan the activities of Dash in the beginning of sprinting. Also before leaving each dash, the new code has gone through some tests.A little group of people will be working on plenty of specific characteristics only. Each gizmo consists of atleast one project manager, a developer, a Tester. One of them will be assigned as Manager of the virtual machine characteristics. Function will be built separately. And the function will combine with the main developed only if the feature is stable. It is not necessary that a team member to work on the same property. Two times they do, they can move to another team characteristics.

Test Strategy

A test strategy is a system that describes the test portion of the application development cycle. It is created to tell project managers, testers & developers on some key issues in the testing system. This includes the aim of testing, new methods of control functions, the total time & resources needed for the project, & the testing surroundings. In the testing strategy describes how the risks of stake holder products are mitigated in the levels of proof, the kinds of tests are performed in the testing levels, & that the entry & exit of the application criteria.The test strategy is created based on design development documents. The design document is the main system used &, sometimes, the conceptual design document can be viewed. The design documents report the application functionality is enabled in the next version. For each set of design development, an appropriate test strategy must be created to test the new feature sets. The purpose of a test strategy is to clarify the main tasks & challenges of the test project. Test Test Architecture approach & are other terms used to report what I am calling the test strategy.
