What is a Traceability Matrix / Requirements Traceability Matrix?

2006-12-24T21:13:00.000Z

The concept of Traceability Matrix is to be able to trace from top level requirements to implementation, and from top level requirements to test. A traceability matrix is a table that traces a requirement to the tests that are needed to verify that the requirement is fulfilled. A good traceability matrix will provide backward and forward traceability, i.e. a requirement can be traced to a test

Have I Tested Enough?

2006-01-04T16:15:00.000Z

One of the most intriguing and difficult questions to answer in any software development life cycle is whether the software is defect free. No matter what the level of maturity of software application, it is next to impossible to say that a software application is defect free. We can answer this question to a certain level by collecting data with regard to the performance and reliability of the

What is Testware?

2005-12-03T00:30:00.000Z

As we know that hardware development engineers produce hardware. Software development engineers produce software. Same like this, Software test engineers produce testware.Testware is produced by both verification and validation testing methods. Testware includes test cases, test plan, test report and etc. Like software, testware should be placed under the control of a configuration management

Levels of testing

2005-12-01T17:54:00.000Z

A step into the world of software testing might seem like a nightmare, with memories of unending test scriptsproviding weeks of tedious repetitive testing and mountains of problem reports. Even after apparently exhaustive testing, bugs are still found, there is rework to carry out and inevitably yet more testing. But with careful planning, software testing can go like a dream.Levels of testing:

Checklist for Acceptance Test

Writing effective test cases

2005-11-22T15:42:00.000Z

Testing cannot ensure complete eradication of errors. Various types of Testing have their own limitations. Consider Exhaustive black box and white box testing, which are practically not "Exhaustive" to the verbose as they are required to be, owing to the resource factors. While testing a Software Product, one of the most important things is the design of effective test cases. A Tester tries to

System Testing

2005-11-16T15:18:00.000Z

This type of test involves examination of all the system for software components, all the hardware components and any interfaces.The whole system is checked not only for validity but also for met objectives. The complete system is configured in a controlled environment, and test cases are developed to simulate real life scenarios that occur in a simulated real life test environment. System

Boundary Value Analysis (BVA)

2005-11-08T15:45:00.000Z

Boundary value analysis is a technique for test data selection. A test engineer chooses values that lie along data extremes. Boundary values include maximum, minimum, just inside boundaries, just outside boundaries, typical values, and error values. The expectation is that, if a systems works correctly for these extreme or special values, then it will work correctly for all values in between. An

The Testing Estimation Process

2005-10-28T15:36:00.000+01:00

One of the most difficult and critical activities in IT is the estimation process. I believe that it occurs because when we say that one project will be accomplished in such time by at such cost, it must happen. If it does not happen, several things may follow: from peers’ comments and senior management’s warnings to being fired depending on the reasons and seriousness of the failure.Here are a

Testing - when requirements are changing continuously

2005-10-21T20:30:00.000+01:00

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... - In the project's initial schedule, allow for some extra time to

Difference between Verification and Validation

2005-10-17T15:20:00.000+01:00

Verification ensures the product is designed to deliver all functionality to the customer; it typically involves reviews and meetings to evaluate documents, plans, code, requirements and specifications; this can be done with checklists, issues lists, walkthroughs and inspection meetings. You CAN learn to do verification, with little or no outside help. Validation ensures that functionality, as

Difference between Alpha and Beta Testing

2005-10-14T15:40:00.000+01:00

Alpha testing is final testing before the software is released to the general public. First, (and this is called the first phase of alpha testing), the software is tested by in-house developers. They use either debugger software, or hardware-assisted debuggers. The goal is to catch bugs quickly. Then, (and this is called second stage of alpha testing), the software is handed over to us, the

How do you execute tests?

2005-10-13T15:48:00.000+01:00

Execution of tests is completed by following the test documents in a methodical manner. As each test procedure is performed, an entry is recorded in a test execution log to note the execution of the procedure and whether or not the test procedure uncovered any defects. Checkpoint meetings are held throughout the execution phase. Checkpoint meetings are held daily, if required, to address and

How do you create a test plan/design?

2005-10-12T15:14:00.000+01:00

Test scenarios and/or cases are prepared by reviewing functional requirements of the release and preparing logical groups of functions that can be further broken into test procedures. Test procedures define test conditions, data to be used for testing and expected results, including database updates, file outputs, report results.. Test cases and scenarios are designed to represent both typical

How do you create a Test Strategy?

2005-10-11T16:41:00.000+01:00

The test strategy is a formal description of how a software product will be tested. A test strategy is developed for all levels of testing, as required. The test team analyzes the requirements, writes the test strategy and reviews the plan with the project team. The test plan may include test cases, conditions, the test environment, a list of related tasks, pass/fail criteria and risk assessment.

What is software testing methodology?

2005-10-10T18:36:00.000+01:00

A software testing methodology is the use of a three step process of:1. Creating a test strategy;2. Creating a test plan/design; and3. Executing tests.This methodology can be used and molded to your organization's needs. Using this methodology is important in the development and in ongoing maintenance of the customers' applications.

Usability Testing

The scope of this phrase, however, can

Performance measurement parameters for a tester

2005-10-04T17:20:00.000+01:00

Software testing is not about finding bugs. It's about delivering great software. No customer ever said with a straight face, "Wow! You found and fixed 65,000 bugs—that must be really great software!" So, why do many currently use bug counts as a measurement tool? The answer is simple: Bugs are just so darn countable that they are practically irresistible. They can be counted, tracked, and used

Test Case Maintenance

2005-09-30T16:10:00.000+01:00

Changes to Product features can happen many times during a product development lifecycle. These may be driven by change of customer requirements, design changes or some times as late as customer acceptance tests. Many times, making necessary changes reported by customers can be crucial. In such scenarios test cases drawn by Test Engineers can become obsolete rendering the whole effort in test

KPA in CMM

2005-09-28T16:28:00.000+01:00

The Key Process Areas (KPAs) define "building blocks" based on industry best practices. Theultimate goal is to establish "continual improvement" of the software engineering process and the resulting products. The KPAs of lower levels focus mainly on management processes (and industry minimal standards). While the KPAs of higher levels focus more on organizational and technical processes (and more

Localization Testing

2005-09-27T15:39:00.000+01:00

Around one year ago I got the shock of my life as a tester when my Lead asked me to test our product for the localized versions. I was supposed to test our product on French and German platforms and one can imagine my condition as I didn’t have a faintest idea about either French or German. That was my first encounter with Localization Testing. It was not as bad as it sounds and in fact after a

Exploratory Testing

2005-09-22T15:20:00.000+01:00

Have you ever tested a piece of software that you were not very familiar with? Also, you might not have had the luxury of ready-made test cases at hand and could not afford spending time to write them. Nevertheless you went ahead to test the product and did a quite a good job. If you remember, it required a lot of logical thinking, formulating your thoughts into test cases in real time and

What You Don't Know May Help You

2005-09-21T15:32:00.000+01:00

Some testers take it upon themselves to learn as much as possible about the inner workings of the system under test. This type of "gray box" testing is valuable, and most testers have the technical wherewithal to grasp much of what's going on behind the scenes. But it's important to recognize that sometimes "ignorance is strength" when it comes to finding problems that users will encounter.When

Spike Testing

2005-09-19T15:56:00.000+01:00

Spike Test is used in terms of Load/Performance testing. Spike Tests are tests that use real-worlddistributions and user communities, but under extremely fast ramp up and ramp down times. It is common to execute stress tests that ramp up to 100% or 150% of expected peak expected user-load in a matter of minutes rather than about an hour.

Need of Test Plan and Test Cases for testing

2005-09-17T15:13:00.000+01:00

Test Plan identifies the test activities and also defines the objective, approach, and schedule of intended testing activities, while Test Cases comprises of the test procedure, test conditions and expected result.

Smoke Testing

2005-09-13T16:02:00.000+01:00

Smoke testing is a relatively simple check to see whether the product "smokes" when it runs. Smoke testing is also sometimes known as ad hoc testing, i.e. testing without a formal test plan.With many projects, smoke testing is carried out in addition to formal testing. If smoke testing is carried out by a skilled tester, it can often find problems that are not caught during regular testing.

Difference between System Testing and Integration Testing

2005-09-12T15:44:00.000+01:00

System testing is high level testing, and integration testing is a lower level testing. Integration testing is completed first, not the system testing. In other words, upon completion of integration testing, system testing is started, and not vice versa. For integration testing, test cases are developed with the express purpose of exercising the interfaces between the components. For system

How can software QA processes be implemented without stifling productivity?

2005-09-10T15:33:00.000+01:00

Implement QA processes slowly over time. Use consensus to reach agreement on processes and adjust and experiment as an organization grows and matures. Productivity will be improved instead of stifled. Problem prevention will lessen the need for problem detection. Panics and burnout will decrease and there will be improved focus and less wasted effort. At the same time, attempts should be made to

Do automated testing tools make testing easier?

2005-09-08T17:25:00.000+01:00

Yes and no. For larger projects, or ongoing long-term projects, they can be valuable. But for small projects, the time needed to learn and implement them is usually not worthwhile. A common type of automated tool is the record/playback type. For example, a test engineer clicks through all combinations of menu choices, dialog box choices, buttons, etc. in a GUI and has an automated testing tool

Installation Testing

2005-09-05T15:15:00.000+01:00

Installation testing is often the most under tested area in testing. This type of testing is performed to ensure that all Installed features and options function properly. It is also performed to verify that all necessary components of the application are, indeed, installed.Installation testing should take care of the following points: - 1. To check if while installing product checks for the

Regression Testing

2005-09-02T15:07:00.000+01:00

Regression testing as the name suggests is used to test / check the effect of changes made in the code.Most of the time the testing team is asked to check last minute changes in the code just before making a release to the client, in this situation the testing team needs to check only the affected areas.So in short for the regression testing the testing team should get the input from the

Content Management Testing

2005-09-01T14:01:00.000+01:00

‘Content Management’ has gained a predominant importance after the Web applications took a major part of our lives. What is Content Management? As the name denotes, it is managing the content.

This is crucial to the

Rapid Testing

2005-08-30T16:31:00.000+01:00

Rapid testing means testing software faster than you do now, while maintaining or improving your standards of quality. Unfortunately, there is no simple way to achieve rapid testing. The figure shows a somewhat simplistic sketch that represents rapid testing as a structure that is built on a foundation of four components. If any of these components is weak, the effectiveness of testing will be

Introducing Automated Software Testing in your project

2005-08-26T15:51:00.000+01:00

Rules for Automation

2005-08-25T15:20:00.000+01:00

Rule #1 of automation: "If you can not logically describe what you are testing, you can't automate it."If you are testing specific items, then you may be able to do it. (e.g. Click on a specific button, check for the title of the box, fill in the box, check to make sure that the grayed out button becomes available). But for the UI test to be able to figure out that the background is not grayed

What if there isn't enough time for thorough testing?

2005-08-24T15:12:00.000+01:00

Since it's rarely possible to test every possible aspect of an application, every possible combination of events, every dependency, or everything that could go wrong, risk analysis is appropriate to most software development projects. Use risk analysis to determine where testing should be focused. This requires judgment skills, common sense and experience. The checklist should include answers to

Bug Count Vs Test Coverage

2005-08-17T13:51:00.000+01:00

Bug counts on a project speak volumes about the quality of testing for a particular product and how vigorous the test team is working to "assure quality". Bug counts are invariably a primary area of test metrics that are reported to management. What is the rationale behind drawing so much attention to the number of bugs being found through the course of a project? I

When to start and stop Testing?

2005-08-16T19:32:00.000+01:00

Testing is sometimes incorrectly thought as an after-the-fact activity; performed after programming is done for a product. Instead, testing should be performed at every development stage of the product. Test data sets must be derived and their correctness and consistency should be monitored throughout the development process. If we divide the lifecycle of software development into “Requirements

Difference between Load and Stress Testing.

2005-08-05T18:48:00.000+01:00

One of the most common misuse of terminology is treating "Load Testing" and "Stress Testing" as synonymous. The consequence of this ignorant semantic abuse is usually that the system is neither properly "load tested" nor subjected to a meaningful stress test.1. Stress testing is subjecting a system to an unreasonable load while denying it the resources (e.g., RAM, disc, mips, interrupts, etc.)

For starters, formal training and gaining experience in both:1. Manual testing, and2. Quality AssuranceTechnical:1. Understanding of systems and software2. Programming skills are helpfulSkills a good SQA person has to have:- 'test to break' attitude, - Ability to take the point of view of the customer, - Strong desire for quality, - Attention to detail. - Tact and diplomacy are useful in

Gray Box Testing

2005-08-04T13:43:00.000+01:00

Even though you probably don't have full knowledge of the internals of the product you test, a test strategy based partly on internals is a powerful idea. This can be called as gray box testing. The concept is simple: If you know something about how the product works on the inside, you can test it better from the outside. This is not to be confused with white box testing, which attempts to cover

Black box/white box testing

Black-box and white-box are test design methods. Black-box test design treats the system as a "black-box", so it doesn't explicitly use knowledge of the internal structure. Black-box test design is usually described as focusing on testing functional requirements. Synonyms for black-box include: behavioral, functional, opaque-box, and closed-box. White-box test design allows one to peek inside the

Acceptance TestingTesting the system with the intent of confirming readiness of the product and customer acceptance. Acceptance testing, which is a black box testing, will give the client the opportunity to verify the system functionality and usability prior to the system being moved to production. The acceptance test will be the responsibility of the client; however, it will be conducted with

What is Testing?

2005-07-27T16:27:00.000+01:00

Testing is the process of identifying defects, where a defect is any variance between actual and expected results.Defect can be caused by a flaw in the application software or by a flaw in the application specification. For example, unexpected (incorrect) results can be from errors made during the construction phase, or from an algorithm incorrectly defined in the specification. Testing is
