Requirements changing continuously?

Work with management early on to understand how requirements might change, so that alternate test plans and strategies can be worked out in advance. It is helpful if the application's initial design allows for some adaptability, so that later changes do not require redoing the application from scratch. Additionally, try to-

• Ensure the code is well commented and well documented; this makes changes easier for the developers
• Use rapid prototyping whenever possible; this will help customers feel sure of their requirements and minimize changes
• In the project's initial schedule, allow for some extra time to commensurate with probable changes

What should be done after a bug is found ?

When a bug is found, it needs to be communicated and assigned to developers that can fix it. After the problem is resolved, fixes should be re-tested. Additionally, determinations should be made regarding requirements, software, hardware, safety impact, etc., for regression testing to check the fixes didn't create other problems elsewhere. If a problem-tracking system is in place, it should encapsulate these determinations. A variety of commercial, problem-tracking/management software tools are available. These tools, with the detailed input of software test engineers, will give the team complete information so developers can understand the bug, get an idea of its severity, reproduce it and fix it.

Test Case

A test case is a document that describes an input, action, or event and its expected result, in order to determine if a feature of an application is working correctly. A test case should contain particulars such as a
a. Test case identifier; or Test Case ID
b. Test case name;
c. Objective; or Test Case Description
d. Test conditions/setup; or Steps
e. Input data requirements, or Actions
d. Expected result
e. Actual Result
f. Test Log or Test Case Status (Pass/Fail)
Please note, the process of developing test cases can help find problems in the requirements or design of an application, since it requires you to completely think through the operation of the application. For this reason, it is useful to prepare test cases early in the development cycle, if possible.

Test Plan

A software project test plan is a document that describes the objectives, scope, approach and focus of a software testing effort. The process of preparing a test plan is a useful way to think through the efforts needed to validate the acceptability of a software product. The completed document will help people outside the test group understand the why and how of product validation. It should be thorough enough to be useful, but not so thorough that none outside the test group will be able to read it

What's a Good Design

Design could mean many things, but often refers to functional design or internal design. Good functional design is indicated by software functionality can be traced back to customer and end-user requirements. Good internal design is indicated by software code whose overall structure is clear, understandable, easily modifiable and maintainable; is robust with sufficient error handling and status logging capability; and works correctly when implemented

What's a Good Code

A good code is code that works, is free of bugs and is readable and maintainable. Organizations usually have coding standards all developers should adhere to, but every programmer and software engineer has different ideas about what is best and what are too many or too few rules. We need to keep in mind that excessive use of rules can stifle both productivity and creativity. Peer reviews and code analysis tools can be used to check for problems and enforce standards

Quality

Quality software is software that is reasonably bug-free, delivered on time and within budget, meets requirements and expectations and is maintainable. However, quality is a subjective term. Quality depends on who the customer is and their overall influence in the scheme of things. Customers of a software development project include end-users, customer acceptance test engineers, testers, customer contract officers, customer management, the development organization's management, test engineers, testers, salespeople, software engineers, stockholders and accountants. Each type of customer will have his or her own slant on quality. The accounting department might define quality in terms of profits, while an end-user might define quality as user friendly and bug free
