How to create an assertion

Assertions are implemented in the 'assertions' folder of the tutorial-compiler directory. To implement a new assertion create a new typescript file with the name of your assertion in this directory.

Inside the new typescript file create a new class. The class has to to implement a static 'run' method as shown below. In this method you can check whatever you want.

export class YourAssertionCode {
    public static run(): void {
        ...your code goes here...
        if(somethingIsWrong){
            throw new Error("Your error message");
        }
    }
}

After this you have to add the newly created assertion to the Assertion class of the index.ts file. This file is located in the same directory.

public yourAssertionCode(): Assertions {
        YourAssertion.run();
        return this;
    }

If you want to pass arguments to this method, you have to do this in the header of the 'run' method and in the call of the method.
