Defect life cycle is a cycle which a defect goes through during its lifetime. It starts when defect is found and ends when a defect is closed, after ensuring it’s not reproduced. Defect life cycle is related to the bug found during testing. [Read more…] about What is a Defect Life Cycle or a Bug lifecycle in software testing?
What is the cost of defects in software testing?
The cost of defects can be measured by the impact of the defects and when we find them. Earlier the defect is found lesser is the cost of defect. For example if error is found in the requirement specifications during requirements gathering and analysis, then it is somewhat cheap to fix it. The correction to the requirement specification can be done and then it can be re-issued.
In the same way when defect or error is found in the design during design review then the design can be corrected and it can be re-issued. But if the error is not caught in the specifications and is not found till the user acceptance then the cost to fix those errors or defects will be way too expensive.
If the error is made and the consequent defect is detected in the requirements phase then it is relatively cheap to fix it. [Read more…] about What is the cost of defects in software testing?
When do defects in software testing arise?
Because of the following reasons the software defects arise:
- The person using the software application or product may not have enough knowledge of the product.
- Maybe the software is used in the wrong way which leads to the defects or failures.
- The developers may have coded incorrectly and there can be defects present in the design.
- Incorrect setup of the testing environments.
To know when defects in software testing arise, let us take a small example with a diagram as given below. [Read more…] about When do defects in software testing arise?
From where do defects and failures in software testing arise?
Defects and failures basically arise from:
- Errors in the specification, design and implementation of the software and system
- Errors in use of the system
- Environmental conditions
- Intentional damage
- Potential consequences of earlier errors

What is a Failure in software testing?
If under certain environment and situation defects in the application or product get executed then the system will produce the wrong results causing a failure. [Read more…] about What is a Failure in software testing?
