constructor(sandbox) {
			this.sandbox = sandbox;
			this.#resetMocks();
			// stub the `fireThemeApplied`` method away as it sporadically requires
			// sap/ui/core/theming/Parameters which hinders the tests' expectations
			this.sandbox.stub(ThemeManager, "fireThemeApplied");
		}
Helper class that simplifies the creation of mocks and expectations
