jasmine test wasn't run when injected string contains \

I'm currently trying to write a jasmine unit test to test that my password field does not contain special characters.

Alas, the following unit test works:

it("should display error for string:'1special char ~'", function() {
      mockControls.password.val("1special char ~");
      mockControls.confirmpassword.val("1special char ~");
      mockControls.submitpassword.click();
      expect(...)
});

But this one doesnt:

it("should display error for string:'1special char \\'", function() {
      mockControls.password.val("1special char \\");
      mockControls.confirmpassword.val("1special char \\");
      mockControls.submitpassword.click();
      expect(...)
});

When the latter unit test is run, jasmine (using resharper unit test runner in VS2013) responds with "Inconclusive: Test wasn't run"

Any clue on why this is?

note that mockControls is created like thus:

var mockControls = {
    password: $('<input type="password" id="password"/>'),
    confirmpassword: $('<input type="password" id="confirmpassword"/>'),
    submitpassword: $('<input id="submitpassword"/>')
}
