    override func setUp() {
        super.setUp()
        formatter = CurrencyFormatter()

    }
    
    func testShouldBeVisible() throws {
        let result = formatter.breakIntoDollarsAndCents(929466.23)
        XCTAssertEqual(result.0, "929,466")
        XCTAssertEqual(result.1, "23")
    }
    
    func testDollarsFormatted() throws {
        let result = formatter.dollarsFormatted(929466.23)
        XCTAssertEqual(result, "$929,466.23")
    }
    
    func testZeroDollersFormatted() throws {
        let result = formatter.dollarsFormatted(0)
        XCTAssertEqual(result, "$0.00")
    }
}
