What is Defect Life Cycle or Bug Life Cycle in Software Testing

We have seen the Software Development Life  Cycle in one of our previous blogs. V-model, Iterative models are examples of how software can be developed. The Software Test Life Cycle is a part of the Software Development Life Cycle. And the Test Life Cycle  is used for System Testing and for User Acceptance Testing. The Test Life Cycle […]

What is Defect or Bugs or Faults in Software Testing

Defects are the most visible part of the Software Test Process. Defects found in Production/Live environment and by customer are termed ‘Failures’. Any testing team is evaluated by the number found during testing and the failures encountered by the customer. If the customer encounters a vast number of failures, the efficacy of the testing team […]

ISTQB -User Acceptance Testing(UAT)

User Acceptance Testing (UAT) We have so far in our blogs looked at Unit testing, Integration testing and System testing in detail. In today’s blog, we take a look at User Acceptance Test or UAT for short. UAT comes after System testing. Though the application has undergone these different tests, the customer (the king/queen) has […]

ISTQB- System Testing

 System Testing or Functional Testing System Testing is the next level of testing after Unit and Integration Testing. In System testing,  end to end testing is conducted in an environment representative of the live or production environment. The test cases are based completely on the Functional Specification. And an independent test team(independent of the development […]

ISTQB – Integration Test Strategies

Integration strategy stands for HOW individual modules will be combined together during Integration testing. The individual modules can be combined together in one go or they can be joined one by one. A decision on how to put the pieces together is called the Integration Strategy. There are 3 strategies – Big Bang, Top Down Integration & Bottom […]

ISTQB – Unit Testing & Integration Testing

Tests conducted by Developers In our blog on V-model, we looked at how for every phase in the SDLC,  a corresponding testing activity was introduced. So we have Unit Testing,  Integration Testing, System Testing and  User Acceptance Testing. Of these, the Unit Testing and Integration Testing are primarily the responsibility of the Development team. The […]

ISTQB – Different Test Types

In our blog on V-model, we looked at how for every phase in the SDLC,  a corresponding testing activity was introduced. So we have Unit Testing,  Integration Testing, System Testing and  User Acceptance Testing. And  each of these different test levels have a specific objective or goal eg. at Integration testing, we focus on the […]

ISTQB – Test Levels

Test Levels In our previous blog we understood how the V-model extends the waterfall model with the testing activities that need to be completed later in SDLC. And for every development activity we saw a corresponding testing activity. And how the test phase for a given level began during the corresponding  software development activity. During the Requirements phase, testers reviewed […]

ISTQB V-model of Testing

In the traditional waterfall model, which is a linear or sequential model, each activity in the software development life cycle is more or less complete before the next stage begins. The Requirements phase kicks off the project. In the Requirements phase, requirements were collected or elicited from the Customer and captured in a document called […]

ISTQB Software Test Life Cycle

Software Test Life Cycle or the Software Test Process The Software Test Life cycle addresses the Testing aspect of the Software Development Life Cycle. It includes all activities from Test Planning, writing test cases, test execution to QA sign-off. Many organizations have a team that is independent of the Development team or a part of the […]
