To detect software failures so defects can be corrected.

When one defect hides the presence of another defect.

Process of checking if software meets business and technical requirements.

Process of confirming that software is built correctly as per specifications.

International standard for software quality characteristics.

A mistake in software code that causes incorrect behavior.

When a number exceeds storage capacity in programming, causing errors.

Testing can show presence, but not absence of errors.

A testing phase to verify software modules against specifications and design, ensuring total coverage of requirements.

A phase that tests interactions between software modules to ensure they work together as designed.

A process to confirm that software meets business requirements and is error-free before integration with hardware.

A type of testing that evaluates the complete and integrated software system to ensure compliance with specified requirements.

An assessment to verify that separate systems function together correctly after integration, focusing on interactions and dependencies.

Occurs when the observed behavior of the software does not match the expected behavior, impacting functionality.

The cause of an error in a system, originating from defects in software or hardware.

A system state that can potentially trigger a failure, indicating there's something wrong in the code or logic.

The overall probability that a system will perform its intended function without failure.

The probability that a hardware component will fail during operation.

The probability that a software component will produce incorrect outputs.

The probability that a system user will make an error while operating the system.

For two independent components: P(S) = P(A) + P(B). If replicated: P(S) = P(A)^n.

Techniques to prevent faults during the safety lifecycle of a system.

The ability to keep functioning despite faults or errors present.

An example of failure due to a software error related to data type conversion.

Automated oracles used in class testing to verify method outcomes.

A mechanism that checks if outputs from programs meet expected results.

An oracle providing approximate results for limited test inputs.

An oracle using statistical properties to analyze outcomes.

Compares results across multiple executions for similarity.

Uses the same model to validate system behavior.

Difficulties in capturing complex inputs and outputs for testing.

The process by which results from tested software are evaluated by the oracle.

The process of identifying and fixing bugs in software code.

The process of executing code to identify bugs under known conditions.

Testing is systematic; debugging is exploratory.

A mechanism to determine if a test has passed or failed.

Testing performed by individuals not involved in development.

Challenges include being viewed as a beginner's task and often an afterthought.

It’s impossible to completely test a system for all bugs.

Programmers often find bugs, but may miss many.
