Run tests selectively (a surefire plugin feature):

# doesn't compile nor run tests
mvn -Dmaven.test.skip=true package
# compiles tests but doesn't run tests
mvn -DskipTests package
# compile/run only one test class
mvn -Dtest=<TEST_CLASS> test
# run only one test method
mvn -Dtest=<TEST_CLASS>#<TEST_METHOD> test

Find out Java CA certs file location:

But Java keytool knows the location with -cacerts option.

List all trusted CA certificates:

$ keytool -storepass changeit -list -cacerts
Keystore type: JKS
Keystore provider: SUN

Your keystore contains 128 entries

debian:ac_raiz_fnmt-rcm.pem, Jun 21, 2022, trustedCertEntry, 
Certificate fingerprint (SHA-256): EB:C5:57:0C:29:01:8C:4D:67:B1:AA:12:7B:AF:12:F7:03:B4:61:1E:BC:17:B7:DA:B5:57:38:94:17:9B:93:FA

# 1. load the server certificate
echo -n | openssl s_client -connect <HOST>:<PORT> -showcerts | openssl x509 -out <PEM_FILE>
# 2. save the certificate to the keystore file (file is created if not exists)
keytool -storepass <PASSWORD> -keystore truststore.jks -alias <ALIAS> -importcert -trustcacerts -file <PEM_FILE>
# list keystore content
keytool -storepass <PASSWORD> -keystore truststore.jks -list -v
# delete alias
keytool -storepass <PASSWORD> -keystore truststore.jks -delete
# change keystore file password
keytool -storepasswd -keystore truststore.jks
Enter keystore password: <OLD_PASSWORD>
New keystore password: <NEW_PASSWORD>
Re-enter new keystore password: <NEW_PASSWORD>
