Set up your project with the given starting code. The files should compile and run, but either no tests will berun, or tests will run but be failing.2. For this project, start by uncommenting the first TEST_CASE in the assg11-tests.cpp file. These are the unittests to test the functionality of your BinaryTree insert() function, the class recursive method you are toimplement.13. Add the insert() public and private prototypes to the BinaryTree.hpp header file.4. Add a stub for your two insert() member function to the BinaryTree.cpp implementation file. The publicinsert() is a void function so it can initially be empty. The private version of the function should return apointer to a BinaryTreeNode, so you should create a new node and return it initially from this function.5. Your code should compile and run now. Make sure after adding the public and private stub methods your codecompiles and runs. However, your unit tests will be failing initially.6. Incrementally implement the functionality of your insert() member functions. Most of the work is actuallydone by the private insert() function. You should try to add no more than 2 or 3 lines of code, and thenmake sure your program still compiles and runs. Start by adding code to get the first failing test to pass. Thenonce that test passes, move on to the next failing t
