Why are there no changes on the test server after deployment?

Question

Software Deployment

Hello, there are 3 servers,

• DEV - for developers
  
• TEST - for testers, deployed from dev
  
• PROD - for the tester, before showing the client, it is deployed from the test.
  

After the deployment from to DEV, all new fisi and fixes are there. In jenkins, I run the deployment for the test (I don’t see any errors), there are simply no changes.
Deploy seems to pass without errors.
How can this be? Where to dig, where to look? Thanks to.

Answer 1

Em.
First of all, you need to look at the logs.
If there is not enough information there, you pick the deployment scripts and add a lot of echo there at all important points so that the logs are useful and understandable.
Then look at the logs again.
Again, there is no information on this subject at all. Jenkins can be configured very flexibly, no one knows for common phrases. Maybe you have independent jobs for deploying to different environments, maybe you have a groove pipeline, maybe something else.

Answer 2

Do you use different Git branches to deploy to DEV, TEST, PROD?
If so, maybe you didn't update the branch for TEST?
