How to run all test cases even if one test case fails

Question

func Test_something(t *testing.T) {
    // TEST CASE1: pass an array 
      // some logic here

    // TEST CASE2: pass an EMPTY array --> this will cause test to fail
      // some logic here

    // TEST CASE3: pass something else 
      // some logic here

I am writing some unit tests but I am not sure if it's possible to run a test Test_something that has several test cases without stopping the execution of other test cases if one fails. Or does it even make sense?

In console I would like to see something like this.

TESTCASE1: SUCCESS <message>
TESTCASE2: FAIL <message>
TESTCASE3: SUCCESS <message>

At the moment I get something like this:

TESTCASE1: SUCCESS <message>
TESTCASE2: FAIL <message>

It will naturally stop executing after TESTCASE2 fails.

I have not used GO language yet but other languages have one function for one test case. — Jirka Picek, Jul 19 '22 at 11:01
Can you provide more details about your test function. Specially the assertion of the test steps is interesting. — guenhter, Jul 19 '22 at 11:02
You can achieve that with subtests; see https://go.dev/blog/subtests#table-driven-tests-using-subtests — jub0bs, Jul 19 '22 at 11:03
When you have only one function and run log.fatal() or a similar function then it will abort in GO's native Unit Test enviroment — h0ch5tr4355, Jul 19 '22 at 11:19

with t *testing.T you may call:

t.Errorf(...): it will not stop next tests.
t.Fatalf(...): it will stop next tests.

See official doc.

You can use subtest with the help of the testing.T.Run function. It allows to gather several test cases together and have separate status for each of them.

func TestSomething(t *testing.T) {
    t.Run("first test case", func(t *testing.T) {
        // implement your first test case here
    })
    t.Run("second test case", func(t *testing.T) {
        // implement your second test case here
    }
}
