6 Background ● Partner service used Docker for developing ● Development with Docker became more complicated ● We want to run the test without setting up the docker container ● Partner service only dependent on authority service, so only we need fake-authority container now

7 Background ● Partner service used Docker for developing ● Development with Docker became more complicated ● We want to run the test without setting up the docker container ● Partner service only dependent on authority service, so only we need fake-authority container now

8 Without fake-authority ● Use authority-sdk instead of ‘fake-authority’ container ● Authority-sdk can issue FAKE PAT(Private Access Token) ● The key pair generated (↑) must also be used on the grpc server ● Put the keyID, public Key in environment variable ● If grpc server starts and environment variable is not empty (that is ‘test mode’), use already generated key Test starts E2E_FAKE_AUTH_KEY_ ID
 hoge
 E2E_FAKE_AUTH_PRIV ATE_KEY
 
 E2E_FAKE_AUTH_PUB LIC_KEY
 
 GRPC server starts if environment variable exists, fetch it

9 Some trouble ● The same test case sometimes passes and sometimes it doesn’t ( token is expired error occurred but token expires 1 day later..why ? 😭) ● authority-sdk provides some similar functions, I didn’t find which ones is appropriate for this situation

10 Some trouble ● The same test case sometimes passes and sometimes it doesn’t ( token is expired error occurred but token expires 1 day later..why ? 😭) ● authority-sdk provides some similar functions, I didn’t find which ones is appropriate for this situation because I didn’t know that Go time duration ‘ type is nanosecond

11 Some trouble ● The same test case sometimes passes and sometimes it doesn’t ( token is expired error occurred but token expires 1 day later..why ? 😭) ● authority-sdk provides some similar functions, I didn’t find which ones is appropriate for this situation I issued new subjectID every time, but authority-sdk provides better function I used WithFakePAT, but this returns PAT without digital signature
