Compilation error on Remix IDE

I am trying to compile my contracts on Remix IDE. I am getting error in the test contract:

pragma solidity ^0.5.3; 
contract STFB5 { 
    function transferToFallback(address payable _to) public payable { 
    function() external payable{ 
    function getBalance() public view returns (uint) { 
        return address(this).balance; 
    constructor () payable public{ 


pragma solidity ^0.5.3; 
contract F5 { 
    function() external payable { 
        // send / transfer (forwards 2300 gas to this fallback function) 
        // call (forwards all of the gas) 
    constructor () payable public {} 
    function getBalance() public view returns (uint) { 
        return address(this).balance;

contract testSuite { 
    /// 'beforeAll' runs before all other tests 
    /// More special functions are: 'beforeEach', 'beforeAll', 'afterEach' & 'afterAll' 
    F5 obj1; 
    STFB5 obj2; 
    function beforeAll() public payable { 
       uint a = 100; 
       obj1 = new F5{value: a}(); 
       obj2 = new STFB5{value: a}(); 
    function initialValueofObj1ShouldBe100() public returns (bool) { 
       return Assert.equal(obj1.getBalance(), 100, "initial value is not correct"); 
    function initialValueofObj2ShouldBe100() public returns (bool) { 
       return Assert.equal(obj2.getBalance(), 100, "initial value is not correct"); 

But I am getting the error:

contracts/STFB5_test.sol:28:21: ParserError: Expected ';' but got '{' 
obj1 = new F5{value: a}(); 

Somebody please guide me.
