Test tables for unit testing

[GuilhermeMLS]

Test tables are an elegant way of reducing the amount of duplicated code when unit testing. The template project could have some test table examples.

func TestFoo(t *testing.T) {
	testTable := []struct {
		testName string
		expectedErr error
		// add more variables to the test case here
	} {
		{
			testName: "it should foo bar baz",
			expectedErr: errors.New("foo"),
		},
	}
	for _, testCase := range testTable {
		t.Run(testCase.testName, func(t *testing.T) {
			// Arrange
			
			// Act
			
			// Assert
		})
	}
}

Notice that test tables don't completely replace normal test cases. There are moments we simply should not use test tables.
