It’s tempting to stay up all night in a futile attempt to locate the source of a nasty bug.
That said, your tests could have bugs too … Step Away
PHPSTORM DOCKER NODE DEBUG CODE
Tests can be run as the code is developed to prove a function works and spot any issues as further changes are made.
Test-driven Development (TDD) is a development process which encourages developers to write code which tests the operation of a function before it’s written - for example, is X returned when function Y is passed input Z.
Online source repositories often offer basic issue tracking, but dedicated solutions may be appropriate for larger teams and projects. Adopt an Issue-tracking Systemĭoes a bug exist if no one knows about it? An issue-tracking system is used to report bugs, find duplicates, document reproduction steps, determine severity, calculate priorities, assign developers, record discussions, and track progress of any fixes.

It becomes easier to discover where and when a bug was introduced and who should receive the blame! Online repositories such as GitHub and Bitbucket offer free space and management tools. However, most linters have code editor plugins, such as ESLint for VS Code and linter-eslint for Atom which check your code as you type:Ī source control system such as Git can help safe-guard your code and manage revisions. These are often installed as global Node.js modules so you can run checks from the command line: eslint myfile.js The popular options for JavaScript and Node.js include ESLint, JSLint, and JSHint. Use a Code LinterĪ linter can report code faults such as syntax errors, poor indentation, undeclared variables, and mismatching brackets before you save and test your code. Node.js devs are spoiled for choice with free editors such as VS Code, Atom, and Brackets, as well as plenty of commercial alternatives. Similar to a breakpoint, except the program is stopped when a variable is set to a specific valueīugs can often be prevented before you test your application … Use a Good Code EditorĪ good code editor will offer numerous features including line numbering, auto-completion, color-coding, bracket matching, formatting, auto-indentation, variable renaming, snippet reuse, object inspection, function navigation, parameter prompts, refactoring, unreachable code detection, suggestions, type checking, and more.

Typographical errors, such as g()Īn error caused by a user rather than the application, but may still incur an update depending on that person’s seniorityĪ variable to examine during debugger execution The historical list of all functions called before the error occurred For example, data loss would normally be considered more problematic than a UI issue unless the frequency of occurrence is very low When running line by line, complete execution of a command without stepping into a function it calls When running line by line, complete execution of the current function and return to the calling code When running code line by line in a debugger, step into the function being called User incompetence disguised as a bug report, typically followed by a response to “Read The Flipping Manual” Re-emergence of a previously fixed bug perhaps owing to other updatesĪ bug which is similar or related to another Rewriting code to help readability and maintenance Hard-to-trace bugs dependent the sequence or timing of uncontrollable events Where a bug is allocated on a list of planned updates The program works but doesn’t act as intended Output of runtime information to the console or a file The most-often made but least useful bug reportĪn instruction to a debugger to show the value of a variable at a point during execution How often or under what conditions a bug will occur All developers say it at some point during their career The point at which a debugger stops a program so its state can be inspectedĪ tool which offers debugging facilities such as running code line by line to inspect internal variable statesĪs in the claim: “it’s not a bug, it’s a feature”. Terminologyĭebugging has its own selection of obscure jargon, including the following: Term Fortunately, Node.js has some great tools to help trace errors. Finding that bug is another matter, and developers can spend many unhappy hours trying to locate the source of an issue. Fixing a bug is often easy - a corrected character or additional line of code solves the problem.
