== Code quality
== Code quality
- automated tests
- coding standards and consistent formatting
- check for higher level types of errors (bug patterns)
== Tools for automatic code checking
- Checkstyle (https://checkstyle.sourceforge.io/index.html)
- Spotbugs (https://spotbugs.readthedocs.io/en/latest/index.html)
- Pmd (https://pmd.github.io)
- Sonarcube (https://www.sonarqube.org/)
- ...
== Checkstyle
- static analysis
- finds errors like
** references to variables with undefined value
** variables that are never used
** syntax and coding standards violations
** dead code blocks
== Checkstyle (2)
- naming conventions
- line length
- whitespace
- Javadoc comments
- annotations
== Checkstyle (3)
- can be configured to use a certain set of checks
- extendable - one can write own checks
- plugins for IDEs
[background-color = "#124990"]
[color = "#fff6d5"]
== Checkstyle examples
== Spotbugs
- checks bytecode and not the source
- looks for "bug patterns"
- example:
```
An apparent infinite loop (IL_INFINITE_LOOP)
This loop doesn't seem to have a way to terminate (other than by perhaps throwing an exception).
```
== Spotbugs (2)
- extendable
- plugins for Maven Gradle Ant
- Eclipse IDE integration
