This is not doing anything useful. It's just validating "bindata/network/iptables-alerter/002-script.yaml contains the strings that we put into bindata/network/iptables-alerter/002-script.yaml". Notably, if someone added a new field to the event and failed to quote it, this test would not catch that.

It should probably just be removed. (iptables-alerter will be going away soon anyway.)

g := NewGomegaWithT(t)

bootstrapResult := fakeBootstrapResult()
bootstrapResult.IPTablesAlerter.Enabled = true

objs, err := renderIPTablesAlerter(&operv1.NetworkSpec{}, bootstrapResult, manifestDir)
g.Expect(err).NotTo(HaveOccurred())

var scriptCM *uns.Unstructured
for _, obj := range objs {
if obj.GetKind() == "ConfigMap" && obj.GetName() == "iptables-alerter-script" {
scriptCM = obj
break
}
}
g.Expect(scriptCM).NotTo(BeNil())

script, found, err := uns.NestedString(scriptCM.Object, "data", "iptables-alerter.sh")
g.Expect(err).NotTo(HaveOccurred())
g.Expect(found).To(BeTrue())

// Unquoted YAML 1.1 booleans such as yes/no/true/false/on/off unmarshal as
// bool and crash kubectl when metadata.namespace/name must be strings.
g.Expect(script).To(ContainSubstring(`namespace: "${pod_namespace}"`))

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert both namespace fields separately.

The rendered script contains both metadata.namespace and regarding.namespace. This assertion only proves that one namespace: "${pod_namespace}" occurrence is quoted. If either field loses its quotes, the test can still pass. Assert both YAML paths separately, or assert that the quoted namespace occurs exactly twice.

Suggested test change 
-	g.Expect(script).To(ContainSubstring(`namespace: "${pod_namespace}"`))
+	g.Expect(script).To(ContainSubstring("metadata:\n  namespace: \"${pod_namespace}\""))
+	g.Expect(script).To(ContainSubstring("regarding:\n  namespace: \"${pod_namespace}\""))

In `@pkg/network/iptables_alerter_test.go` at line 35, Update the assertion for
rendered script in the relevant test to verify both metadata.namespace and
regarding.namespace are present with quoted pod_namespace values, rather than
checking only one generic namespace occurrence; use distinct YAML-path
assertions or an exact count of two quoted occurrences.
