String Known Value Checks

The known value checks that are available for string values are:

`StringExact` Check

The StringExact check tests that a resource attribute, or output value has an exactly matching string value.

Example usage of StringExact in an ExpectKnownValue plan check.

func TestExpectKnownValue_CheckPlan_StringExact(t *testing.T) {
    t.Parallel()

    resource.Test(t, resource.TestCase{
        // Provider definition omitted.
        Steps: []resource.TestStep{
            {
                // Example resource containing a computed string attribute named "computed_attribute"
                Config: `resource "test_resource" "one" {}`,
                ConfigPlanChecks: resource.ConfigPlanChecks{
                    PreApply: []plancheck.PlanCheck{
                        plancheck.ExpectKnownValue(
                            "test_resource.one",
                            tfjsonpath.New("computed_attribute"),
                            knownvalue.StringExact("str")),
                    },
                },
            },
        },
    })
}

`StringRegexp` Check

The StringRegexp check tests that a resource attribute, or output value has a string value which matches the supplied regular expression.

Example usage of StringRegexp in an ExpectKnownValue plan check.

func TestExpectKnownValue_CheckPlan_StringRegexp(t *testing.T) {
    t.Parallel()

    resource.Test(t, resource.TestCase{
        // Provider definition omitted.
        Steps: []resource.TestStep{
            {
                // Example resource containing a computed string attribute named "computed_attribute"
                Config: `resource "test_resource" "one" {}`,
                ConfigPlanChecks: resource.ConfigPlanChecks{
                    PreApply: []plancheck.PlanCheck{
                        plancheck.ExpectKnownValue(
                            "test_resource.one",
                            tfjsonpath.New("computed_attribute"),
                            knownvalue.StringRegexp(regexp.MustCompile("str"))),
                    },
                },
            },
        },
    })
}
