Static Analysis definition
- Static analysis, also called static code analysis, is a method of computer program debugging that is done by examining the code without executing the program.
Static Analysis purpose
- One the primary uses of static analyzers is to comply with standards.
- So, if you’re in a regulated industry that requires a coding standard, you’ll want to make sure your tool supports that standard.
Static Analysis time
- Static code analysis is performed early in development, before software testing begins :
- For organizations practicing DevOps, static code analysis takes place during the “Create” phase.
Static Analysis tools benefits
- The best static code analysis tools offer speed, depth, and accuracy :
- It takes time for developers to do manual code reviews.
- Automated tools are much faster.
- Static code checking addresses problems early on.
- And it pinpoints exactly where the error is in the code.
- So, you’ll be able to fix those errors faster.
- Plus, coding errors found earlier are less costly to fix.
- Testing can’t cover every possible code execution path.
- But a static code analyzer can.
- It checks the code as you work on your build.
- You’ll get an in-depth analysis of where there might be potential problems in your code, based on the rules you’ve applied.
- Manual code reviews are prone to human error, automated tools are not.
- They scan every line of code to identify potential problems.
- This helps you ensure the highest-quality code is in place — before testing begins.
- After all, when you’re complying with a coding standard, quality is critical.
Static Analysis practice
- Static Analysis is performed in a non-runtime environment.
- Typically, a static analysis tool will inspect program code for all possible run-time behaviors and seek out coding flaws, back doors, and potentially malicious code.
- Static code analysis is a method of debugging by examining source code before a program is run.
- It’s done by analyzing a set of code against a set (or multiple sets) of coding rules.
