Jasmine 2.0 async done() and angular-mocks inject() in same test it()

My usual test case looks like

it("should send get request", inject(function(someServices) {
     //some test
}));

And Jasmine 2.0 async test should look like

it("should send get request", function(done) {
     someAsync.then(function(){
         done();
     });
});

How can I use both done and inject in one test?

Solution 1:

This should work; I ran into the same problem when I updated to Jasmine 2.0

it("should send get request", function(done) {
    inject(function(someServices) {
        //some async test
        done();
    })(); // function returned by 'inject' has to be invoked
});

Solution 2:

An IMPORTANT note is the brackets after the inject call. Eg.

inject(function(someServices) {
   //some async test
   done();
})();  <-- these brackets here important.

If you look at the type of inject:

export declare function inject(tokens: any[], fn: Function): () => any;

You can see it returns a function, so you were getting no output because you forgot to call the function!!

If you think about it, it makes sense that it returns a function, because it takes a function!

So the extra parentheses should solve all problem!

Working Example:

  it('should allow you to observe for changes', function(done) {
    inject([GlobalStateService], (globalStateService: GlobalStateService) => {
      globalStateService.observe("user", storageType.InMemoryStorage, (user: string) => {
        expect(user).toBe("bla");
        done();
      });

      globalStateService.write({ user: "bla"}, storageType.InMemoryStorage);
    })();
  });
