DevOps Foundations: Examine Your Code with Static Analysis
In this lab, you'll practice performing static analysis with two different linters (static analysis tools). By the end of the lab, you'll understand how to leverage static analysis to improve your code.
Terms and conditions apply.
Challenge
Get Started in the Lab Environment
Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!
Challenge
Perform Static Analysis with a Python Linter
You’ll examine a Python file that runs just fine, but has some room for improvement, and then execute a Python linter to lay out what those opportunities are.
Challenge
Correct Code to Satisfy the Python Linter
You'll review the results of the analysis and find a particular problem listed therein. You will then find the problem in the code, make an adjustment, and then re-run the analysis to verify that the problem has been resolved.
Challenge
Perform Static Analysis on JavaScript with ESLint
You'll execute ESLint against a JavaScript file, review the results, and disable analysis of a single line of code.
Challenge
Correct Code to Satisfy the JavaScript Linter
You'll execute ESLint against a JavaScript file, and use "autofix" to correct the problems.
