Allow concurrent tests with bun test

[eduardvercaemer]

What is the problem this feature would solve?

Consider the following example, where tests are not CPU bound but rather wait on other resources:

describe("async-tests", () => {
  it("waits 2 seconds", () =>
    new Promise((resolve) => setTimeout(resolve, 2000)));

  it("waits another seconds", () =>
    new Promise((resolve) => setTimeout(resolve, 2000)));
});

There's currently no way of running such tests concurrently so that it takes 2 seconds. Instead they always run sequentially and take 4 seconds in total.

What is the feature you are proposing to solve the problem?

a) A flag for bun test that runs all tests concurrently
b) A solution like jest's test.concurrently()

What alternatives have you considered?

Failed to find any alternative 🤷🏼‍♂️
