testdbs

Utility package to start and stop different DBs in tests

Usage

Modify your tests

Modify the Main test function to initialize the DBs before the tests are run and to delete after

func TestMain(m *testing.M) {
	testdbs.InitDBS()
	// main block that runs tests
	code := m.Run()
	err := testdbs.Clean()
	if err != nil {
		os.Exit(1)
	}
	os.Exit(code)
}

And then in your tests you can iterate over the DBs

func TestMyFunction(t *testing.T) {
    for _, db := range testdbs.DBs() {
        t.Run(dbt.DbType(), func(t *testing.T) {
            db := dbt.Conn()
            // db is *gorm.DB
		})
	}
}

if you need to isolate DBs, e.g. run multiple tests on the same db/table you can use ConnDbName("custom") to crete a new database wit the passed name.

note: connections will be reused cross tests for every db name

func TestMyFunction(t *testing.T) {
    for _, db := range testdbs.DBs() {
        t.Run(dbt.DbType(), func(t *testing.T) {
            db := dbt.ConnDbName("custom")
            // db is *gorm.DB
		})
	}
}

running tests

As a default calling go test will only start an embedded sqlite on a temp directory, to run the tests with all the supported DBs you need to call go test -alldbs
