// Initialize a global array
global.myArray = [];

describe('My test suite', function() {
    it('should be able to access the global array', function() {
        // Add elements to the global array
        global.myArray.push('element1', 'element2');
        
        // Access the global array
        console.log(global.myArray); // Output: ['element1', 'element2']
    });
});
