 The continuous integration runs a set of [gherkin integration tests](https://github.com/open-feature/test-harness/blob/main/features).

+## TLS
+
+To run the integration tests against a `flagd` instance configured to use TLS, do the following:
+
+Generate a cert and key in the repository root
+```
+openssl req -x509 -out localhost.crt -keyout localhost.key \
+  -newkey rsa:2048 -nodes -sha256 \
+  -subj '/CN=localhost' -extensions EXT -config <( \
+   printf "[dn]\nCN=localhost\n[req]\ndistinguished_name = dn\n[EXT]\nsubjectAltName=DNS:localhost\nkeyUsage=digitalSignature\nextendedKeyUsage=serverAuth")

+build the `flagd` binary
+```
+make build
+```
+then run the `flagd` binary with tls configuration
+```
+./flagd start -f file:test-harness/testing-flags.json -c ./localhost.crt -k ./localhost.key
+```
+finally, either run the tests with an explicit path to the certificate:
+```
+make ARGS="-tls true -cert-path ./../../localhost.crt" integration-test
+```
+or, run without the path, defaulting to the host's root certificate authorities set (for this to work, the certificate must be registered and trusted in the host's system certificates)
+```
+make ARGS="-tls true" integration-test
+```
