Basic TypeScript Project in Visual Studio 2015

1. Create a new TypeScript project in VS 2015.

• Remove app.ts file.

2. Add greeter.ts file.

• Add breakpoint to greet function

• Uncomment code to invoke greet

• Press F5 to debug.

  class Greeter {
      constructor(public message: string) {
      }
  
      greet(): string {
          return "Hello " + this.message;
      }
  }
  //new Greeter("World").greet();

3. Install Jasmine packages.

   Install-Package jasmine
   Install-Package jasmine.typescript.DefinitelyTyped
   

4. Add greeter.spec.ts file.

   /// <reference path="greeter.ts"/>
   /// <reference path="Scripts/typings/jasmine/jasmine.d.ts"/>
   
   describe("Greeter", () => {
   
       describe("greet", () => {
   
           it("returns Hello World", () => {
   
               // Arrange
               var greeter = new Greeter("World");
   
               // Act
               var result = greeter.greet();
   
               // Assert
               expect(result).toEqual("Hello World");
           });
       });
   });

5. ReSharper will run the tests, but it cannot debug them.
