+# Tests
+
+Building tests:
+
+```sh
+$ cd EVerest
+$ mkdir build
+$ cd build
+$ cmake -GNinja -DEVEREST_CORE_BUILD_TESTING=ON ..
+$ ninja install
+```
+
+`touch release.json` may be needed if it hasn't been created
+(then re-run `ninja install`).
+
+## Unit tests
+
+- `./tls_test` and `./patched_test`
+- automatically runs `pki.sh`
+- run from the directory containing the executable
+
+## Standalone server
+
+- Run `pki.sh` to build the test certificates and keys
+- use openssl_s_client to make test connections
+- run from the directory containing the executable
+
+### Standalone TLS server
+
+Tests the Server class in isolation.
+
+- `./tls_server`
+- connects to IPv4 and IPv6
+- only one connection at a time
+- gracefully terminates after 30 seconds
+- `valgrind` can be used to check memory allocations (should be none)
+- requires client certificate and supports `status_request` extension
+- s_client echos back what is typed
+
+```sh
+openssl s_client -connect localhost:8444 -verify 2 -CAfile server_root_cert.pem -cert client_cert.pem -cert_chain client_chain.pem -key client_priv.pem -verify_return_error -verify_hostname evse.pionix.de -status
