A failure of a white box test may result in a change that requires all black box testing to be repeated and white box testing paths to be reviewed and possibly changed.

White-box testing is a software testing method that focuses on the internal structure of the code. This type of testing is often used to identify defects in the code, such as logic errors, syntax errors, and data-handling errors.
Failure in white-box testing can have a number of impacts, including:
Increased cost of development: If defects are not identified and fixed early in the development process, they can be more expensive to fix later on. This is because it may take longer to find the root cause of the defect, and the fix may require changes to more code.
Reduced quality of the software: Defects can lead to unexpected behavior, crashes, and data corruption. This can make the software unusable or unreliable, and it can damage the reputation of the software vendor.
Increased risk of security vulnerabilities: Defects can also introduce security vulnerabilities into the software. These vulnerabilities can be exploited by attackers to gain unauthorized access to the system or to steal data.
In addition to these general impacts, failure in white-box testing can also have specific impacts on different types of software. For example, failure in white-box testing of medical software could lead to patient harm. Failure in white-box testing of financial software could lead to financial losses.
To avoid these impacts, it is important to use effective white-box testing techniques. These techniques include:
Unit testing: This involves testing individual units of code, such as functions or classes.
Integration testing: This involves testing groups of units of code together.
System testing: This involves testing the entire system as a whole.
It is also important to use a variety of testing techniques, such as code coverage, mutation testing, and fuzz testing. Code coverage measures how much of the code is tested by the test suite. Mutation testing involves making small changes to the code and then checking if the test suite fails. Fuzz testing involves feeding the software invalid or unexpected data to see if it crashes.
By using effective white-box testing techniques, software developers can identify and fix defects early in the development process, thereby reducing the cost of development, improving the quality of the software, and reducing the risk of security vulnerabilities.
