Cargo + Maven + Two Tomcats

Recently I've been struggling to make Maven execute two Tomcat instances (with different applications on different ports). I decided to put a solution here so you don't have to discover it by yourself.

Bad Tests Good Tests - True, False and Magic Switches

Bad Tests Good Tests - Modification of Global State

For unit tests a rule of thumb is to keep them independent from each other. It is not so bad if we introduce a dependency on purpose (and explicitly declare it e.g. using TestNG dependsOnMethod feature). A worse scenario is when we are not aware of the dependency ourselves. This can bring serious problems on our heads.

A Glimpse of Awaitility

Today I had a task to first deploy a webapp and then verify whether it was properly deployed. Obviously there are things to consider:

  • it takes time till the app is deployed and started,
  • it is hard to say how long it takes.

One solution would be to wait for some safe time (2 minutes? 3 minutes?) and then check if the app responds to requests. Yes, but it would be definitely more efficient to do it in some kind of a loop, so you do not waste too much time if, for example, everything is up and ready in 1 minute 20 seconds.


This used to be my blog. I moved to long time ago.
