Most of the tests pass for me:

TF_ACC=1 go test ./internal/framework/service/turnstile/ -v -run "^TestAccCloudflare" -count 1 -timeout 120m -parallel 1
=== RUN   TestAccCloudflareTurnstileWidget_Basic
=== PAUSE TestAccCloudflareTurnstileWidget_Basic
=== RUN   TestAccCloudflareTurnstileWidget_Minimum
=== PAUSE TestAccCloudflareTurnstileWidget_Minimum
=== CONT  TestAccCloudflareTurnstileWidget_Basic
--- PASS: TestAccCloudflareTurnstileWidget_Basic (2.39s)
=== CONT  TestAccCloudflareTurnstileWidget_Minimum
--- PASS: TestAccCloudflareTurnstileWidget_Minimum (1.68s)
PASS
ok      github.com/cloudflare/terraform-provider-cloudflare/internal/framework/service/turnstile        4.083s

If I run TestAccCloudflareTurnstileWidget_NoDomains I get,

=== CONT  TestAccCloudflareTurnstileWidget_NoDomains
    resource_test.go:118: Step 1/2 error: Error running apply: exit status 1

        Error: Error creating challenge widget

          with cloudflare_turnstile_widget.zxoheflslb,
          on terraform_plugin_test.tf line 12, in resource "cloudflare_turnstile_widget" "zxoheflslb":
          12:   resource "cloudflare_turnstile_widget" "zxoheflslb" {

        error from makeRequest: invalid value for `domains`: not entitled to use
        empty list
--- FAIL: TestAccCloudflareTurnstileWidget_NoDomains (0.53s)

guessing my testing account doesn't have the entitlement needed.
