I have 2 microservices. In one there is a workflow, and other contains the activity. I want to write a unit test for just running the activity without depending on it’s workflow. Is this possible with TestActivityEnvironment? Is there any sample that i can refer to?
Yes you can use TestActivityEnvironment, see simple example here: temporal-java-workshop/ContentLengthActivityTest.java at main · tsurdilo/temporal-java-workshop · GitHub

Hi @tihomir ,
Facing one issue while testing my activity. My activity has two methods in it. When I test them individually, it works fine. But when I run the whole test class, one method executes with success, but other fails with following error:

You can reproduce this with temporal-java-workshop/ContentLengthActivityTest.java at main · tsurdilo/temporal-java-workshop · GitHub by copying the already present method and renaming it and running the test class.
Can reproduce. Seems an issue with calling testEnv.close() after each test method. Opened issue here.
Also updated the used sample test that runs fine and does not call testEnv.close().
Thanks for reporting this.
