On our site there is an icon that hides/unhides the menu. I created the following script to test it :
it('Hamburger Menu Click Validation', function () {
expect(Hamburger_Menu.isDisplayed());
Hamburger_Menu.click();
browser.sleep(1000);
expect(foo.isDisplayed()).toBe(false);
Hamburger_Menu.click();
browser.sleep(1000);
expect (foo.isDisplayed().toBe(true));
// expect (invisibilityOf())
})
The statement "expect(foo.isDisplayed()).toBe(false);" is copied from this website. I do not see any reason for its failure, but when I run the test I get the following error, which says that :foo.isDisplayed(...).toBe is not a function!! . How can I validate if the menu gets hidden using expect function?
