Test succeeded when a panic occurs Follow

Today I had the following issue: I have written a test where I tried to access an element in a slice which is not available.
In the log I received the following error message: panic: runtime error: index out of range [10] with length 2
But: The test in the GoLand IDEA itself succeeded!?

By executing the test in the terminal I got the following output:

panic: runtime error: index out of range [10] with length 2 [recovered]
panic: runtime error: index out of range [10] with length 2

goroutine 55 [running]:
testing.tRunner.func1.1(0xaff200, 0xc0002bbba0)

panic(0xaff200, 0xc0002bbba0)
...
FAIL

Go version used:
go version go1.14 linux/amd64

I can reproduce the failure by writing a test which only panics:

func Test_Foo(t *testing.T) {
   panic("foo")
}
