Most Linux distributions have the GNU Compiler Collection (GCC) installed and macOS users can get the Clang tools with Xcode. To thoroughly test this function, you want to throw at it every conceivable input: valid strings, mistyped strings (off by one or two characters, or containing invalid characters), strings that are too short or too long, blank strings, null arguments, strings containing control characters (non-text codes), string containing HTML, strings containing injection attacks (such as SQL commands or JavaScript code), and so on. Did you find any anwser that allow to run JavaScript from the browser perspective? To add the key binding, in VSCode UI menu, go 'Code' > 'Preferences' > 'Keyboard Shortcuts'. With all the arguments and expected return values in hand, you now write the tests themselves, which are pieces of code that call the function with a particular input, then compare the actual return value with the expected return value (this comparison is called an assertion): The exact structure of the code depends on the test framework you're using, and specific examples are provided later in this article. Not code written using Visual Studio. Try using the zip file instead of the installer. It contains a list of the variables defined so far in your running kernel.
