XCTestExpectation just hangs

Question

I have no idea what's going on. I'm using an expectation in my test and it will not timeout. I've removed so much of my test that now I'm just left with:

func testItem() {
    let expec = expectation(description: "expection")
    wait(for: [expec], timeout: 3.0)
}

And it won't fail. It just hangs. Does anyone know why this might be happening?

Answer 1

If you are using XCTestCase.expectation(description:), which adds the returned XCTestExpectation to self.expectations, you should use waitForExpectations instead of wait(for:).

When using wait(for:) you should be creating your expectations using XCTestExpectation(description:).
