The figure below depicts the elementary execution paths for the possible control flows in source code.Įach circle is called a node and represents a statement.
#DEBUGGIN XSCOPE CODE#
Source code is executed sequentially by the CPU the order in which the different statements are executed is referred to as the execution path. Reason enough to have a closer look to debugging, I would argue. According to Coralogix, solving a bug takes 30 times longer than writing a line of code.
#DEBUGGIN XSCOPE SOFTWARE#
Debugging might be one of the most underestimated activities of a software development team. Simply stated, debugging are the activities performed to root-cause and resolve a malfunction of the software, or in short, solving that bug. This implies there is another, not yet mentioned, important and time consuming activity to be performed by a software development team debugging. However, it seems to be that on average a developer creates ~70 bugs per 1000 lines-of-code of which ~15 will find their way to the user of the software. When considering the core activities of a software development team, typical one would come up with the following activities requirements engineering, design & modeling, coding & unit testing, functional testing, system testing, acceptance testing, and not to forget configuration management and tool management & support. In a terminal, execute /Applications/Google\ Chrome.By Ger Cloudt, author of “What is Software Quality?” Image by mohamed Hassan from Pixabay Or in a command prompt, execute /chrome.exe -remote-debugging-port=9222 In the "target" field, append -remote-debugging-port=9222
Right click the Chrome shortcut, and select properties You must launch Chrome with remote debugging enabled in order for the extension to attach to it. "name": "Launch index.html (without sourcemaps)", Use the snippet below to get the whole picture (you cannot directly change the value, but you can use $eval anyway!) scopeCopy = function (scope) /app/files", The difference between scope.bla and scope.$eval('bla') is the former does not consider the prototypically inherited values. scope.$eval(expression) is very handy when you want to quickly check whether an expression has the expected value. If you are changing the value directly, remember to use scope.$digest() to reflect the changes on UI. This is exactly what you get when you are using the latest version of Batarang. Get a scope linked to an elementĭepending on whether there exists a directive that creates an isolate scope, you can retrieve the scope by angular.element($0).scope() or angular.element($0).isolateScope() (use $($0).scope() if $ is enabled). The latest selected element will be stored in variable $0 in console. Alternatively you can also click on any element in Elements tab in Chrome, for example. In many non-IE browsers, you can select an element by right clicking an element and clicking "Inspect Element".
I did a lot of breakpoints not only in my own code, but also in angular.js itself, but sometimes it is simply not the most effective way.Īlthough the methods below are very powerful, they are definitely considered to be bad practice if you actually use in production code, so use them wisely! Get a reference in console from a visual element IMHO, the most frustrating experience comes from getting / setting a value of a specific scope related to an visual element.
