[Bug] Tests run inside arrow function are not listed and lacking names

Bug

• Version of Majestic: v1.8.0
• Version of Jest: 26.0.20
• Version of Node: v15.12.0
• Operating System: Windows 10 Pro 20H2

Reproduction:

Test evaluated inside arrow function (in order to be used multiple times with different parameters) is sometimes detected by Majestic as one, nameless test entry in GUI, or not visible at all

// calc.test.ts
import { add } from "./calc";

const testAdd = (a: number, b: number, expected: number) => {
  test(`should '${a}' + '${b}' be '${expected}'`, () => {
    var result = add(a, b);
    expect(result).toBe(expected);
  });
};

testAdd(1, 1, 2);
testAdd(2, 2, 4);
testAdd(2, -1, 1);

// calc.ts
export function add(a: number, b: number): number {
  return a + b;
}
