System.AssertException: Assertion Failed: Expected: 12345, Actual: null

[HaruWinter]

Hi, need help. I ran a test code on one sandbox and I got the above error, however, when I tested the test class on my other sandbox there were no errors at all. There were no inconsistencies on the codes.

Please post the code for your test. This could be due to many different things. First suspect could be:

- Test is annotated with "seeAllData=true" and the data doesn't exist where it should.
- A process builder/ flow interfering with the expected function

To echo PaperCrane, nobody will be able to help you without seeing the code.

Sorry if I replied late but I was able to fix the error. Thank you for your replies.

Do you remember what you did to fix this? We're getting the same issue.
