Software testing:
Software testing is a process of executing a program or application with the intent of finding the software bugs. It can also be stated as the process of validating & verifying that a software program or application or product:
- Meets the business and technical requirements that guided its design and development
- Works as expected
- Can be implemented with the same characteristic. .
- Process: Testing is a process rather than a single activity.
- All Life Cycle Activities: Testing is a process thats take place throughout the Software Development Life Cycle (SDLC).
- The process of designing tests early in the life cycle can help to prevent defects from being introduced in the code. Sometimes its referred as verifying the test basis via the "test design".. .
- The test basis includes documents such as the requirements and design specifications.
- Static Testing:Its done during validation process. For example: unit testing, integration testing, system testing, etc.
- Dynamic Testing: It can test and find defects without executing code.It includes reviewing of the documents (including source code) and static analysis. This is useful and cost effective way of testing. For example: reviewing, walkthrough, inspection, etc.
- Planning: We need to plan as what we want to do. We control the test activities, we report on testing progress and the status of the software under test.
- Preparation: We need to choose what testing we will do, by selecting test conditions and designing test cases.
- Evaluation: During evaluation we must check the results and evaluate the software under test and the completion criteria, which helps us to decide whether we have finished testing and whether the software product has passed the tests..
- Software products & related work products: Along with the testing of code the testing of requirement and design specifications and also the related documents like operation, user and training material is equally important..
