siesta-lite/examples/nodejs/unit-tests/global_variables.t.js

Stress-free JavaScript unit testing and functional testing tool, works in NodeJS and browsers

StartTest(t => {

    MyGlobal = 'some expected global'

    // some globals are expected
    t.expectGlobals('MyGlobal');


    // some are accidental "leak", try to uncomment the following code to see
    // how the leak is detected

    // If you find a global leak, you can use this trick to catch it (uncomment the for loop below first, and run in a modern browser)
    // Object.defineProperty(global, 'i', {
    //     set : () => { debugger; }
    // })

    // t.diag('Testing simple for loop...');
    //
    // // try to uncomment this line to see the report about unexpected global - "i"
    // // please note: this feature is not supported in IE <= 8
    // for (i = 0; i < 10; i++) {}
