  spyOn(keyGen: { (x: T): any }): Spy<T> {
    const targetKey = keyGen(this.nameGenerator);

    assert(typeof targetKey === 'string', `${targetKey.toString()} is not valid target key`);

示例2: function

  toHaveBeenCalledWithSignature: function(): void {
    assert(this.actual.getLastCall(), 'spy was never called');

    let lastCallArgs: Array<any> = this.actual.getLastCall().arguments;
    let desiredCallArgs: Array<any> = Reflect.getMetadata(CALL_SIGNATURE_KEY, this.actual);

    assert(desiredCallArgs, 'No call signature recorded');
