How to run testify setup/teardown with table tests using stretchr/testify in golang?

I'm using testify for testing. I've set up a suite for my tests. However, I'm having trouble using the set up and tear down features when using table tests. Is this by design?

package workflows

import (
    "testing"

    log "github.com/sirupsen/logrus"
    "github.com/stretchr/testify/suite"
)

type UnitTestSuite struct {
    suite.Suite
}

func (s *UnitTestSuite) SetupTest() {
    log.Info("setup")
}

func (s *UnitTestSuite) BeforeTest(suiteName, testName string) {
    log.Info("before test")
}

func (s *UnitTestSuite) AfterTest(suiteName, testName string) {
    log.Info("After test")
}


func (s *UnitTestSuite) Test_TableTest() {

    type testCase struct {
        name string
    }

    testCases := []testCase{
        {
            name: "1",
        },
        {
            name: "2",
        },
    }

    for _, testCase := range testCases {

        s.Run(testCase.name, func() {
            // logic ...
            // NOTE that the SetupTest and BeforeTest do not get called for each test here
        })
    }
}

func TestUnitTestSuite(t *testing.T) {
    suite.Run(t, new(UnitTestSuite))
}

When I run the TestUnitTestSuite I get the following output:

=== RUN   TestUnitTestSuite
--- PASS: TestUnitTestSuite (0.00s)
=== RUN   TestUnitTestSuite/Test_TableTest
time="2021-04-17T07:49:28-04:00" level=info msg=setup
time="2021-04-17T07:49:28-04:00" level=info msg="before test"
    --- PASS: TestUnitTestSuite/Test_TableTest (0.00s)
=== RUN   TestUnitTestSuite/Test_TableTest/1
        --- PASS: TestUnitTestSuite/Test_TableTest/1 (0.00s)
=== RUN   TestUnitTestSuite/Test_TableTest/2
time="2021-04-17T07:49:28-04:00" level=info msg="After test"
        --- PASS: TestUnitTestSuite/Test_TableTest/2 (0.00s)
PASS

Note that setup and before test appear only once in the output even though there are two tests being run.

Is there a way for me to automatically run SetupTest (or some alternative) prior to each of my table tests?

Testify released in v1.8.2 these interfaces to be implemented and be executed at the SubTest level:

func (s *Suite) SetupSubTest() {
    fmt.Println("start subtest")
}
func (s *Suite) TearDownSubTest() {
    fmt.Println("tear down subtest")
}

In your case, you can use the SetupSubTest() to add you the setup logic to be execute before each table test.

This is the intended behaviour of how testify works. The Setup/Before/After are called for the TestSuite rather than per subtest (table test case). There is a Github issue here.

You can just call s.SetupTest() within the loop before you do the actual test.
