示例1: it
it("should run the validator when the value changes", () => {
var a = new ControlArray([]);
var c = new Control(null, Validators.required);
a.push(c);
expect(a.valid).toBe(false);
c.updateValue("some value");
expect(a.valid).toBe(true);
expect(a.errors).toBe(null);
});示例2: describe
describe("valueChanges", () => {
var a: ControlArray;
var c1, c2;
beforeEach(() => {
c1 = new Control("old1");
