Quality

ConceptDefinition
BugAn issue that represents something wrong in the code. If this has not broken yet, it will, and probably at the worst possible moment. This needs to be fixed. Yesterday.
Code SmellA maintainability-related issue in the code. Leaving it as-is means that at best maintainers will have a harder time than they should making changes to the code. At worst, they'll be so confused by the state of the code that they'll introduce additional errors as they make changes.

IssueWhen a piece of code does not comply with a rule, an issue is logged on the snapshot. An issue can be logged on a source file or a unit test file. There are 3 types of issue: Bugs, Code Smells and Vulnerabilities
MeasureThe value of a metric for a given file or project at a given time. For example, 125 lines of code on class MyClass or density of duplicated lines of 30.5% on project myProject
MetricA type of measurement. Metrics can have varying values, or measures, over time. Examples: number of lines of code, complexity, etc. A metric may be either qualitative (gives a quality indication on the component, E.G. density of duplicated lines, line coverage by tests, etc.) or quantitative (does not give a quality indication on the component, E.G. number of lines of code, complexity, etc.)
New Code definitionA changeset or period that you're keeping a close watch on for the introduction of new problems in the code. Ideally this is since the previous_version, but if you don't use a Maven-like versioning scheme you may need to set a time period such as 21 days, since a specific analysis, or use a reference branch.
Quality ProfileA set of rules. Each snapshot is based on a single Quality Profile. See also Quality Profiles
RuleA coding standard or practice which should be followed. Not complying with coding rules leads to Bugs, Vulnerabilities, Security Hotspots, and Code Smells. Rules can check quality on code files or unit tests.
Remediation CostThe estimated time required to fix Vulnerability and Reliability Issues.
SnapshotA set of measures and issues on a given project at a given time. A snapshot is generated for each analysis.
Security HotspotSecurity-sensitive pieces of code that need to be manually reviewed. Upon review, you'll either find that there is no threat or that there is vulnerable code that needs to be fixed.
Technical DebtThe estimated time required to fix all Maintainability Issues / code smells
VulnerabilityA security-related issue which represents a backdoor for attackers. See also Security-related rules.
